The best thing about Solar Power Is that it has an unlimited potential. Learn how to generate domestic solar power, easily and save $1000’s on utility bills. You just need to know how to make your own renewable energy source and today I am going to tell you exactly how to Generate Solar Power.
If you want to learn how to generate domestic solar power, you’ll need to learn some basics on how exactly do Solar Panels work. This way, the entire procedure will be much easier to handle.
The process starts with Solar Modules. They are the main components exposed directly to sunlight. Their main function is to convert the sun’s energy into usable electrical power for your home appliances. To get them correctly installed, solar modules are to be mounted on a steel frame and positioned on your roof top. Power produced by the solar modules is converted from Direct Current (DC) to Alternating Current (AC) through a inverter. Usually, Alternating Current (AC) is the usable electrical power that we need to power the home appliances.
Next, the electrical power transfers from the inverter to the electrical service panel. The electrical service panel is used for distributing the electrical power to different parts of your house for use.
The unused electrical power produced by the solar panels will then be brought into the grid all the way through the utility electric meter. As a result, the meter will be made to spin backwards and this establishes a credit with the utility company in offsetting future usage. This method is known as Net Metering and is completely approved by State Level Electricity Policy.
Learning how to generate domestic solar power isn’t really a difficult task. You don’t require many skills beyond being able to handle wiring & basic tools with care and safety measures.
The raw materials required for building solar panels include:-
All these raw materials can be easily picked up by you from the local hardware store. Photovoltaic cell is the only component that you might have to search online and it can be found easily on eBay.
Quality directions that are easy to follow are vital to find when trying to generate solar power. This will make the building process less stressful and make you happier that you made the choice to do it yourself. Online is just one of the places you are able to find some of these manuals. We have reviewed the best guides available to help you to learn how to build your own Solar Panel System for electricity. Go ahead and check them out NOW……learn how to generate domestic solar power and STOP paying for electricity…FOREVER!

Where can I find a ball-park figure for having central heating installed (UK)?
Are there any sites that will give me an idea how much it will cost to get a central heating system installed in a three bedroom house? There is no mains gas, so it would have to be oil fired or Solar Powered.
There is a new type of electric central heating which can be used with the water filled radiators conventionally associated with a gas boiler. Sorry I have no details on price. Although I’ve hears solar power is expensive to install but saves you money subsequently.
Solar Power Is the energy of the future. Learn how to get the cheapest solar powered lighting systems. A few of the numerous advantages of Solar Energy are first and foremost its free, easy to exploit and is capable to provide more energy than what is needed by most homes and businesses.
You may be aware that a commercially sold Solar Lighting system will have its worth in thousands of dollars. But, did you know you can go solar for a fraction of that cost?
Why Go Solar?
Solar Panels are made up of small Pv Cells, also known as Photovoltaic cells. The PV cells capture sun light and store it in a battery. The energy stored in the battery is then converted into usable electricity using an inverter. Solar power is a renewable resource of energy and free to harness once you have installed solar panels.
Installing ready made solar panels can be pretty expensive and can cost you anywhere from $10,000 – $18,000 to solar power you entire home. You can Solar Power Your whole house for a fraction of this amount if you learn how to build solar powered lighting systems. Building such systems from scratch is cheap and easy; all the necessary raw materials can be easily bought from the local electrical or hardware store. This also cuts down on any further impact on the environment as the solar panels do not go through any manufacturing processes.
Going Solar Is Easy!
Various kits are available to download from different vendors that will teach you to Build Solar powered lighting systems. The downloaded kits include steps for calculating the actual electricity that you need from solar panels based upon your electricity bills. Once you have that information you can start building your own solar panels, typically you can easily build a 100 watt Solar Panel in a day very easily.
Now, that’s not something very substantial, but when you can easily redo the whole process over and over again, you can completely go off-grid with a few days of work and perhaps sell back the extra power back to the utility company. Now, how is that for a change? You’ll get a check from the utility provider!
Save Heaps!
Once you install solar powered lighting systems, they will pay for themselves many times over the course of their life. Generally, solar panels have an average lifetime for 25-30 years requiring no to little maintenance. So, you do the math here and calculate how much you are set to save!

Can Solar Thermal Power solve the worlds energy problems?
According to this link Europe uses 4,000 terawatts of energy but in the normally unusable deserts of North Africa and the Middle East 630,000 terawatts fall unused. If solar thermal plants covered the desert about the size of Austria it could power the whole entire world. The technology is cheap and includes an ability to store the energy for nighttime needs. If all this is possible why are Earth are we not employing this clean, cheap, abundent source of energy?
Solar thermal could do just that at affordable costs. Solar thermal can now produce electricity at as low as 8 cents a watt, and that would be improved by the economy of scale of mass production of the solar plant components.
1% of the Sahara desert could power the whole world.
1% of the deserts in the American southwest could power the whole country.
And solar photovoltaic efficiencey is not stuck at 10% as someone answered. It is closer to 20%.
And that efficiency is rapidly improving and the cost of making solar panels is falling just as rapidly. Solar panel industry experts say they are just a few years away from being at grid parity with coal and gas power plants.
In fact, Nanosolar is already there, being able to produce solar panel complete systems for less money than it takes to build a coal power plant.
And then there is the cost of the coal and the pollution from it.
http://www.brightsourceenergy.com/
“Nanosolar’s founder and chief executive, Martin Roscheisen, claims to be the first Solar Panel Manufacturer to be able to profitably sell solar panels for less than $1 a watt. That is the price at which solar energy becomes less expensive than coal.
With a $1-per-watt panel,” he said, “it is possible to build $2-per-watt systems.
According to the Energy Department, building a new coal plant costs about $2.1 a watt, plus the cost of fuel and emissions, he said.”
from http://www.grinzo.com/energy/index.php/category/solar/
Concentrating Solar Photovoltaic Power plants and solar thermal power plants in the southwest should be a large part of our future energy system.
Shows how we could have 69% solar power in the U.S, by 2050, spending less in taxpayer dollars than we spent building the internet and high speed information highway, and in about the same 35 year time frame.
And by spending about 1/8 as much annually over those years as we now give oil companies in subsidies.
“I’d put my money on the sun & solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.” Thomas Edison, 1931
Solar thermal plants can store heat, which will generate steam driven electricity at night.
“Solar thermal power plants such as Ausra’s generate electricity by driving steam Turbines with sunshine. Ausra’s solar concentrators boil water with focused sunlight, and produce electricity at prices directly competitive with gas- and coal-fired electric power.”
“All of America’s needs for electric power – the entire US grid, night and day – can be generated with Ausra’s current technology using a square parcel of land 92 miles on a side. For comparison, this is less than 1% of America’s deserts, less land than currently in use in the U.S. for coal mines.”
Some of the arguments against wind and solar just don’t make sense, like the argument that they are too intermittent, or not constant.
“There are areas in Denmark and Germany who use more than 40 percent of their electricity from wind. From what I have read, they are less concerned about the intermittency than we are in the United States even though we aren’t at 1 pecent yet. Why? Because we are told by the fossil fuel guys, hey, can’t use wind, can’t use solar, what about the intermittency. If wind gets up to 40 percent of the electricity we use and solar gets up to 40 of the electricity we use, the other percents of electricity we need can be made up from the fossil fuel plants that are still there. If they are run less at full power, they can last a long time. That can be your electricity `battery.’”
“Using mirrors to focus the sun’s heat on one of any various heat-to-electricity converters seems to have separated itself out as being the cheapest form of solar power.”
“Solar energy is the great leveler (unlike oil, which has been the great divider) between the haves and the have nots). No one owns the sun. It can’t be drilled or mined or tied up in financial derivatives.”
(See Here Comes the Sun, February 17, 2007, Commentary, Chipstocktrader.com)
Green Wombat has several articles about solar thermal plants in California and Arizona. California has 9 small pilot plants that were built in the 80s and 90s. They produce 355 megawatts. Two larger plants have been approved for the Mojave Desert at 355 and 500 megawatts. Another is to be built near San Luis Obispo at 175 megawatts. Two or three others are in proposal stage, at up to 800 and 900 megawatts, for two of them.
http://blogs.business2.com/greenwombat/
from the Scientific American article:
“The greatest obstacle to implementing a renewable U.S. energy system is not technology or money, however. It is the lack of public awareness that solar power is a practical alternative—and one that can fuel transportation as well. Forward-looking thinkers should try to inspire U.S. citizens, and their political and scientific leaders, About Solar Power’s incredible potential. Once Americans realize that potential, we believe the desire for energy self-sufficiency and the need to reduce carbon dioxide emissions will prompt them to adopt a national solar plan”
“The huge reduction in imported oil would lower trade balance payments by $300 billion a year, assuming a Crude Oil price of $60 a barrel (average prices were higher in 2007). ”
Together with Wind and other renewable, we can go to clean energy, while ultimately improving our economy as well.
http://www.setamericafree.org/blueprint.pdf
A Blueprint For U.S. Energy Security
From the SetAmerican free document above.
The total of all oil-related external or “hidden” costs of $825 billion per year. This
total is nearly twice the figure authorized for the Department of Defense in 2006.
To put the figure in further perspective, it is equivalent to adding $8.35 to the price
of a gallon of gasoline refined from Persian Gulf oil. This would raise that figure to
$10.73, making the cost of filling the gasoline tank of a sedan $214.60, and of an
SUV $321.90.
And then there’s the $300 billion oil adds to our trade imbalance annually.
You think that makes for a good economy?
There is an unbelievable amounty of disinformation about the potential of renewable energy.
cheapest solar power How to Build Very Cheap Solar Panels and Wind Power Generator and Cut your Electricity Bills by 90%
Solar heating is an excellent way to meet your energy demands through renewable sources that not only help you with reduced costs of operation but also make you go green and reduce your carbon footprint. With Solar Energy, one of the simplest things to do is to use it for heating purposes, and solar heating is increasingly gaining acceptance of people who want to save money and be environmentally responsible citizens. Solar heating doesn’t require you to first convert solar energy to electricity, which can be costly and inefficient for the present technology. Therefore solar heating presents a wonderful opportunity to tap into the infinite potential of the sun to run our lives.
The best thing with using solar heating is that you get lots of incentives, depending on where you live. You can get direct tax benefits and also indirect incentives that will ultimately result in lowering the price even further. This is one reason why you should consider this option seriously right now. Solar heating can be used for a number of sources of your everyday use. Solar heaters provide an excellent way to get a continuous supply of hot water to your home. You can use solar heating not only to heat water but also to heat the space and keep your home warm.
Another important area in which you can use solar heating is your pool for example. You will be surprised to know the amount of energy used by your pool for staying warm and inviting. Why not save on some electricity bills and use solar heating for this purpose? Apart from your pool, you can also get your solar heater installed for ready hot water anytime. The best part about solar heating is that it is quite cheap, which means you will more than cover up for the initial one time installation costs that you incur by running the system for a few years. You can greatly save on the electricity that your house consumes and also do your part in saving the planet in the same step. You couldn’t have asked for a better deal, and there could be no better time to adopt solar heating than now!

I am looking into a installing solar water heating system. Any concerns I need to be aware of ?
Reputable companies or companies to avoid.
What is a standard installation cost ?
Standard warrantees ?
Most Solar Installers are fairly regional, covering a couple of states at most due to travel costs.
I’d start by doing a google search with your town or state and the words “Solar Water Heater“. You may also find some help on the web site for the magazine “Home Power” http://www.homepower.com
Installers can sometimes also be found in the yellow pages.
As for price that varies too, my guess would be about 2-5 thousand dollars. You need to “do the numbers” and calculate the pay-back time. Odds are that it will take many years to get your money back.
Warranties are a function of the installers and are usually only good for as long as that installer is in business.
Things to be concerned about are: 1) You must take care of the system, they require yearly maintenance (mine needs 3-8 hours each year). 2) You will usually be cutting holes through your roof, this adds a bit of risk and, as with #1 can require more maintenance. 3) Hail, you will now have a large sheet of glass (or two) on your roof, don’t forget to check you insurance and upgrade it if the collectors are not currently covered in your policy.
Radiant Floor Heating Radiant Floor Heating for hardwood floors?
gonna get new engineered hardwood floors over concrete floor, thinking of heat between. i only have a electric heat baseboards in my condo, would i save money or benefit if i also get the radiant heat???
you have to do your homework on this. not all hardwood floor is usable with radiant heat. you have to make sure it is before you buy it.usually with radiant heat they bury it in the concrete. there is an electric heat grid that can be put over concrete but again you have to check if it is compatible with the type of flooring you are planning for. good luck

A house is designed to have passive Solar Energy features. Brickwork is to be incorporated into the interior of the house to act as a heat absorber. Each brick weighs approximately 1.8 {rm kg}. The specific heat of the brick is 0.85 {rm{J}}/{rm{g}}cdot {rm{K}}.
How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1700 gal of water?
you make it confusing with all the {rm} stuff… write it like this next time…
1.8 kg / brick
0.85 J/gC.. or 0.85 J/gK… ok?

While fears of global warming may or may not be misplaced, the fact remains that winter is still a fact of life, especially in the northeastern United States. During the cold winter months, few things seem as welcoming as a warm home, cozy rooms, and comfortable living space. There are times however when it seems as if the thermostat may be turned up to 70 degrees, but your comfort level is still nowhere near comfortable. In order to provide the best possible alternative to living in a comfortable home, today’s market offers a wide variety of home heating systems. Many still run on the same principle of heating the air, however. Depending on your budget, requirements, and personal preferences, selecting the right home heating system goes a long way in not only providing comfort, but also in providing savings on home heating bills. It may be time to start considering a radiant floor heating system for a number of reasons.
First used by the Romans and Koreans for heating their bathhouses and palaces, radiant floor heating is today one of the best options you can select for warming up your home interiors effectively and efficiently. The primary characteristic of radiant floor heat is that it generates the heat from beneath and within the floor panels. Instead of heating the air in the room by continuously recirculating and heating the air, the surfaces are now heated. The heat therefore comes from the heated surfaces that heat objects in the room (such as you) directly.
Whether you are building a new home or renovating your old one for the oncoming winters, you can install radiant floor heating systems within an economic budget and suited to your specific needs. Some of the main advantages of radiant floor heat over traditional air heating include:
Heating is accomplished through direct heating of objects. Consider the fact that heated air is always moving. One of the myths of heating is that heat rises. This is not true. Instead, hot air rises. Add to that the fact that your body loses heat to colder surfaces and you can see that heating a room can be a lot like aiming at a moving target.
Air is not recirculated so there is a reduction in dust particles and allergens. Colds and other airborne viruses thrive at room temperature in closed environments. This is why many people get sick in the winter. With radiant heat, air circulates naturally in a space.
Less energy is spent reheating the air, saving you money. Whether you use heating oil, propane, or something else to heat your home, if you are heating through convection, you are using energy to constantly reheat the air. Radiant heat instead keeps a surface hot, eliminating heat sinks in a room. Then it directly heats objects. Money is saved on reheating.
When radiant heating was first introduced in the early 20th century, systems tended to be hydronic; in other words, they employed heated water to heat surfaces. The tubing used was copper so if the copper tubing somehow broke, it rendered the entire radiant floor heating system inoperable. The cost of replacing the pipes tended to be prohibitive, especially since by this time, convection heating units were affordable.
The invention of PEX was a catalyst in bringing back radiant heating as a viable, affordable alternative for indoor climate control. PEX is a cross-linked polyethylene material made of medium to high-density modified polyethylene with improved properties. PEX tubing have been used in the United States since the 1980s. This has become the most widely used material in flexible plumbing piping. It is manufactured by the extrusion process in sizes from ¼”-2″ diameter to copper tube sizes and OD controlled (CTS-OD) dimensions. The thickness of the tube is based on Standard Dimension Ratio 9 (SDR 9) values. Such pipes are available in coils and straight lengths. This kind of tube has less effect on environment than other materials of its kind. Also, it is easier to repair when a leak occurs, unlike the copper tubing of the past. Radiant floor systems that were once left unrepaired could now be made fully operational again.
Some features that are labeled on the pipes include the manufacturer’s name or trademark, standard to which it conforms (ASTM F876, F877, AWWA C904 and/or CSA B137.5), tube size and CTS, material designation code (PEX0006), pressure/temperature rating(s) and SDR9 and also ASTM fittings designations approved for use by the tubing manufacturer. In PEX tubing, an oxygen barrier must be used if there are ferrous components in a radiant heating system. If an oxygen barrier is not used in these systems, the ferrous components will rust.
Hydronic radiant heating systems with PEX tubing are reliable and easier to maintain. In order to take full advantage of what radiant heating has to offer, the system should be comprised of a boiler or hot water heater, manifolds, pumps, thermostat, PEX tubing, and either gypcrete or wood panels. Hydronic systems can be installed under any flooring type, though sometimes the height of the floors needs to be adjusted. With some recent inventions, the process has become much easier; as such products are lightweight and allow the tubes to be fitted into pre-cut wood panels.
With PEX tubing, anyone can take advantage of radiant floor heating systems in their homes. The benefits in terms of comfort, health, and money saving will make up for the cost of replacing your old convection air heating system.
You might be surprised to know that the idea of using Solar Energy is relatively "modern". ancient writings are scientific technology Egyptians and Chaldeans who knew so well developed exploiting solar energy in more simple. We have finally reached the stage where most of the senses is in effect, slowly and steadily, and we use the same knowledge in the form of solar thermal energy to conserve our natural resources.
Natural resources of energy The most powerful is never exhausted, solar energy takes the place of honor alongside with wind and hydro. The use of intelligent methods and judicial options to take advantage of these powerful sources of energy are among the main priorities for Many companies in the environment, and many progressive governments.
Solar thermal can be used not only to heat but the same energy can be used to generate electricity. You can even store up to a certain point, so it may be the heat can be produced for several hours after sunset. This is done by heating substances underground sand Special and use the heat later. parabolic solar collectors can heat water and air. The pumps are used to move the liquid and air to the required average in the pipes.
Energy Solar thermal production of renewable energy and a continuous source of thermal energy at a cost effective way is one of the forms, which are implemented successfully in many buildings commercial and business eco-innovation and households. You can also use solar energy to drive Turbines to generate enormous electricity by the use of powerful solar concentrators and solar collectors.
The extraction of bio-fuels, as oil rigs occupy valuable land that can be used for agricultural purposes. This is certainly not in the case of the creation a Solar Thermal Power plant. Just a couple of hectares of land can be used to establish a fully functional hassle free plan that produce electricity for heating and lighting effects on the condition of sunlight around.
What impact would the use of solar thermal albedo to meet a substantial part of the world's power needs?
I'm interested in this as a contribution to global warming. I heard several commentators refer to this as problem in passing, but can not find sources on the scale of the problem. I am also interested in the impact energy production from sources that create heat of combustion, such as nuclear and biofuels and geothermal energy which has published many heat time.

Using Solar Power to heat your water is one of the most practical and cost effective ways to harness energy from the sun. Solar Thermal Systems absorb the sun’s heat and use it to heat your residence’s own hot water needs. In general, the solar thermal system will easily heat water to 140ºF or higher matching the range of its traditional hot water tank counterpart. Effective systems can collect up to 70 percent of the sun’s energy that reaches them and transfer it to you.
In general there are two types of active water heating systems: direct and indirect.
Direct Solar Water Heating
As implied, direct systems capture the sun’s heat in collectors to directly heat a household’s water supply. The system consists of collector pipes filled with water that are linked to an insulated Storage Tank usually located inside a home. As the sun heats the water inside the pipes, the water flows into the storage tank. Although direct systems are more efficient that indirect ones, they require more maintenance to keep the pipes clear of mineral deposits. Direct solar thermal systems also work best in warmer climates where the system is less prone to freezing.
Indirect Solar Water Heating
Indirect systems do not heat the water directly rather they use fluid with a low-freezing point to absorb radiant energy from the sun. Also termed closed-loop systems, an indirect solar water heating system absorbs the sun’s rays into heat pipes evacuated of air which in turn heats up the pipe’s thin copper laminate located on the back of each pipe. The collection array consists of multiple heating pipes that are mounted and tilted to maximize solar collection.
Often glycol (an ingredient in antifreeze) runs through adjacent pipes within the array and heats up via contact with the copper laminate. As the temperature in the pipes rise, the heat activates a pump that circulates the glycol fluid through a heat exchange coil in the water tank. That coil, in turn, transfers its heat to the water tank and voila, hot water is produced.
Solar Pool and Hot Tub Heating Systems
Solar pool heating systems work on a similar principle to a direct system Solar Hot Water Heater. However, because the water can heat up too much in a solar thermal system, the collector’s glazing is often removed. Using non-glazed pipes or a heating system that resembles a flat black mat prevents the pool water from becoming super-heated as well as reduces costs to the overall system.
While solar pool and hot tub heating systems often are exempted from federal and state monetary incentives and rebates, they often pay for themselves within 1–5 years (depending mostly on where you live).
Radiant Heating Systems For Your Home
You can also use a solar hot water (or thermal) system to heat your home. Rather than transferring the heated water to a domestic hot water heater, the solar hot water system can connect to a radiant floor and/or wall panel radiator.
You can make the collection and distribution system as simple or complicated as you like depending on your location, climate, and intended use. Most radiant heating systems use the collection array to heat water and store it in a large thermal collection tank so that you have enough heat to last at least throughout the night. A general rule of thumb is to have a collection tank that can store 1½ to 2 gallons of water for every square foot of solar collector. That water, in turn, is piped via plastic tubing under floors to create an effective heating system.
Radiant Floor Heating systems have many advantages. They are typically 40 percent more efficient than a forced air heating system and can be zoned so that each room has its own thermostat. Furthermore, radiant floors distribute heat beneath your feet where it naturally rises providing a cozy and evenly distributed heated living space.
Tips for Installing Solar Hot Water Systems
Solar Hot Water Heater Tips for Cooler Climates
In cooler climates during the colder times of the year, an indirect solar hot water system can help lower your energy costs by working as a water preheating system rather than an outright water heater. Preheated water reduces the load on your other energy systems to heat the water.
Another trick to increase the system’s efficiency is to wrap your water tank with an insulation blanket to keep the water sufficiently warm and further minimize the need to rely on traditional power sources to heat your water. (Note that not all water heaters need an insulation blanket. Many of the newer energy-efficient models come with a thicker layer of insulation inside the tank that eliminates the need for additional insulation).
Where to Place a Solar Thermal Collection System
Like other types of Solar Energy systems, solar hot water heating systems work best on south-facing walls with full sun exposure. Because of the collector tubes’ type of construction, the outside elements have less effect on its performance compared to a Photovoltaic collection system; a bit of shade on the thermal array will have a less noticeable impact.
Work with a Solar Pro
As with any solar power upgrade, consulting with a solar professional can help you evaluate your potential savings and determine the type of solar hot water system that’s best for you. Solar Thermal Panels come both as stand-alone collection arrays and as integrated building panels. A solar pro can size your system and help you compare the different options for the collection panels and water tank you may need. And remember, solar domestic water systems often qualify for federal, state, and local tax credits and rebates!
Which is more efficient: electric or solar heating?
I recently did an experiment on this. According to my model, solar panel heating is more efficient. Is this the results that should happen? Why is it more efficient (just a brief little explanation if possible)?
Don’t confuse “green” or cost with engineering efficiency. The efficiency should be calculated as the amount of energy converted into temperature increase of the air or the water (total mass of, say, water times the specific heat of the water time the delta T) divided by the amount of heat put in. If your experiment uses the same mass of water for the solar heater and for electric heater, then heat gained is directly proportional to the delta T (higher delta T = higher efficiency). Then the hard part is figuring out how much heat was put in. With the electric heater, this is straight forward, just calculate Kw-hours or joules. For the solar heating, it is a little more difficult to measure how much heat went in. I would guess that Electric could be more efficient because, with a good design, virtually all the electric power could be converted directly into heating water (with some heat going into the container and some going into radiation heat loss). With solar, there may be more heat going into the container and maybe more radiant heat loss. On the “green” side, the sunlight is free.
Pex Tubing Tube WHAT IS THE SPACING FOR RADIANT FLOOR TUBING?
What is the required spacing between pex tubing in a slab of concrete for optimum performance of a Radiant Floor Heating system?
I did this in the mountains of Colorado using 12 inch spacing and had good results without a heat calculation. The spacing is not ‘required’ but recommended depending upon manufacturer. Most do 12 inch since the wire mesh that you attach the pipes to have 6 inch spacings. The ‘runs’ should be no more than 300 feet long and try to get them as even as possible. The shorter the runs the more even temperature the slab will be when it operating. If you can plan your areas to have a ‘hot’ run next to a ‘cooler’ run of pipe that is best. Like making a big spiral with the pipes 2 feet on center and then halfway reversing and going back the other way so you maintain the spacing but have that hot, cool, hot, cool runs of pipe. This is done because the pipe is transferring heat as it circulates and towards the end of the run can be noticeably cooler. Therefore a floor that is more evenly heated. Always have a closed cell insulation under the pipes. It will still work but it is quite a bit more expensive to run. Hope this helps. By the way this is a great heating method.

What in the World is Pex and Why Would I Use It?
PEX Update Here’s How to use PEX by a bona fide DIYer!
In my last article about my tankless water heater I made several references to as to using PEX. Since I figure not a lot of people understand or even know what PEX is I thought I’d devote this article to a little education for the DIY weekend warrior that may be considering changing over his water heater, but, may not want to get involved with copper and soldering and flux, etc. DIYers, it’s time to look like a hero, again!
What the heck is PEX?
Lets start with a little background about PEX. Here’s some info from Wikipedia:
“Cross-linked polyethylene, commonly abbreviated PEX or XLPE, is a form of polyethylene with cross-links. It is formed into tubing, and is used predominantly in hydronic radiant heating systems, domestic water piping and insulation for high tension electrical cables. It is also used for Natural Gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries. Recently, it has become a viable alternative to polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) or copper pipe for use as residential water pipes. PEX tubing ranges in size from 1/4-inch to 4-inch, but 1/2-inch, 3/4-inch, and 1-inch are by far the most widely used.”
Ok, so we’re not talking about using it for natural gas or offshore drilling, but, we are interested in using it as domestic piping, maybe even for radiant heating, hmmm? Why would we want to use PEX? Here are some of the benefits:
PEX can be used for hot or cold water AND it has fittings to make it adaptable to copper and PVC.
PEX is incredibly FLEXIBLE! This is one of it’s shining properties for us “less talented” DIYer’s. I don’t know how to sweat a copper elbow and really don’t care to learn. But, PEX can be bent into a radius (for example, 3/8″ pipe may be bent to a 4″ radius and 1/2″ pipe to a 5″ radius). Huh, no sweat. (Get it?)
Since less fittings are required there are less points at which a leak can happen. Smart, no? Obviously, the more fittings the more potential “problem” areas. Take out the fittings, take out the leaks.
PEX is also less likely to burst. It’s flexibility also gives it the ability to expand and contract.
If, for some reason you need to repair it, there are easy to use kits that you can purchase.
PEX has all the typical fittings as well, like shutoffs, elbows, etc
Making the Connection
PEX general has two methods for installing it. One is compression (too much work) and the other is insertion (yup, much easier). You don’t even have to use that stinky glue and cleaner like you do for PVC! This is living large.
You’ll find that it comes in rolls, typically 100ft., or in lengths that are generally 10ft. long. If you desire you can get it in red (for the hot water) and blue (for, duh, the cold water) or you can stick with plain old white and mark them yourself.
PEX is generally recommended for interior or buried projects, but, I would check with either the manufacturer or your plumbing supply house for any exterior ideas you may have. PEX piping is freeze damage resistant and can expand and contract as water freezes and thaws within the tubing. No tubing material is freeze-break proof, however, and PEX should be installed using the same locally-prescribed insulation requirements to prevent freezing of any plumbing system.
PEX is the snaps!
One of the best reasons I enjoy using it is the ability to “snap and go”. Just measure your length of pipe, snap it into any connector you using and “go” on down the line. I would also recommend laying it out in a dry run first to determine what types of connectors you may need, if any.
Well, PEX warrior, it’s time to engage and go forth! Your friends and neighbors will stand in awe at your prowess and marvel at your courage. Talk your local supplier and see what you think. The hero in you will emerge.
Soooo, that’s how to use PEX. To get information on my tankless water heater click on the link in my bio.

Solar collectors conditioning systems using solar radiation heating of individual rooms use of Solar Panels. There are many uses of solar warming air, and we can even build using a home help from online sources. This is one type of Solar Thermal system where air is heated in the collector radiation from the Sun and are either transferred directly to the interior space or the medium as a rock bin.
Solar panels are used to operate of such systems. Solar panels heat air which is then transferred in one room. The main component of this system includes solar panels collector duct system and diffusers. In warm air can to work with or without fan. Without fan Air is distributed by the action natural ventilation system.
In agriculture, the food produced sometimes must be kept in warm places, especially during the monsoon. Solar air heater works here. It may increase the temperature of the room so that it is properly heated. Thus the product can stay safe and will not break, because of the humidity.
In a solar heater air works much the same way works as solar collectors. Heater is outside the space open, so that can capture sunlight. He usually consists of solar panels but people use different things. Some used aluminum beverage cans and paint them black. Then they are the board and fit in one frame. Panels or containers should have holes in them, connecting each other so that air travel through them. Hence the cold air from the room by moving boxes and hot air enters the room causes fever. Thus, a solar Air heater is very economical way to heat the room. Instead to use expensive equipment, heating, which require much electricity is definitely a cost effective solution.
The solar heating panels offered by HeatingOnline are manufactured by U.S Solar Heating. They are constructed of high quality lightweight aluminum and polycarbonate heating surfaces. Solar heating is a great way to reduce your heating costs in the winter and provide soothing warm air whenever the sun is out.

Swimming Pool Heat Pumps – A Great Way to Heat Your Pool
It’s a fact – most swimming pools are never at optimal swimming temperatures, and while much of the time the cold shock of the water can be an exciting part of the fun, it’s also great to have the option to warm things up a little. This is where swimming pool heat pumps come in – they’re an opportunity to invest in your home while adding to the fun of family memories, as the kids will never want to leave the healthy fun of the water behind.
There are a number of ways to heat a pool, including the use of swimming pool heat pumps, gas or Solar Panels. Swimming pool heat pumps don’t generate heat. Instead they use electricity to capture heat and move it from one location to another. As the swimming pool’s water is circulated by the pump, it is passed through a filter into which a heat pump is incorporated. The heat pump’s fan draws outside air in, directing it over an evaporator coil containing a liquid refrigerant agent. This agent absorbs the air, becoming a warm gas that then passes through a compressor, becoming hotter as its particles are pushed more closely together.
Passing then through a condenser, which transfers the gas’s heat to the cooler water coming from the other end of the heater device, the gas returns to liquid, and goes back to the evaporator to repeat the cycle. The water returns to the pool, dispersing through it and adding to the pool’s overall warmth.
What this means is that swimming pool heat pumps work better than other kinds of inground heaters for pools, like the kinds that require solar panels. This is because, while they might initially cost a bit more than other heating solutions, their cost is less when seen in the long term because they are less effected by things like weather changes and the absence of sunlight. They’re also likely to last a lot longer than such solutions, as they’ve been refined in their design over many years, while most other in ground pool heaters are in their technological infancy.
The biggest concern when installing swimming pool heat pumps is whether the job’s being done by a qualified professional – obviously any device involving gas and heat coils is not one you want poorly installed, especially if you have kids running around. Also, proper installation can optimize the functionality of the pump.
After this concern, you need to consider whether, regardless of the initial price of installation, you can afford to have a swimming pool heat pump running and eating up electricity. As efficiently as it may operate, if your kids are left unchecked running the heater they could well rack up phenomenal bills unless you establish some way to regiment the amount of power the device uses. Consider buying a pool pump timer to cut off power use at a particular number of kilowatt hours. About the Author

One of the major consumers of electric power in the average home is the water heater. It’s on all day keeping water hot for the dishwasher, washing machine, tub, and shower. All homeowners are aware of this, but short of the significant cost of replacing the hot water tanks with the newer instant on demand water heaters, they feel that little can be done. But there is a solution; solar collectors. The technology for how to Make Solar Power collectors has been available for years, but few know about it. These solar collectors are clean and green devices that will heat water with negligible expense. They operate in the following manner.
Sunlight enters a collector through a glass interface to warm a heat exchanger. Cool water flows into and fills the heat exchanger. The water is heated in the exchanger and kept warm until it is needed. When an output spigot is opened, warm water flows from the heat exchanger, and cool water enters to replace it. These heat exchangers are extremely efficient and work to provide hot water whenever the system receives adequate sunlight. The following steps describe the processes involved to make solar power collectors.
1. Build a frame for the collector by cutting pine studs into two 3-foot lengths and two 4-foot lengths. 2. Screw the ends of the 3-foot lengths into the ends of the 4-foot lengths to create a rectangular frame. 3. Lay out a rubber mat onto the floor and cover it with aluminum foil. 4. Place the wooden frame on top of the foil. 5. Screw the rubber mat onto the wooden frame. 6. Lay the heat exchanger inside the frame. 7. Lay the piece of glass on top of the frame sandwiching the heat exchanger inside. 8. Caulk the glass to secure it to the frame. 9. Connect the heat exchanger inlet to the cold water source. 10. Connect the heat exchanger outlet to the hot water source. 11. Position the solar collector at a slight angle to the direct sunlight 12. Turn on the cold water. 13. As the heat in the heat exchanger rises, water from the heat exchanger outlet willrise as well.
The supply of hot water from smaller solar collectors is usually enough to supply a shower or the needs of a small bathroom. Areas with greater demand such as kitchens and laundry rooms will require that you make solar power collectors that are larger. Use caution when working at the collector’s output end. Water temperature can be as high as 110 degrees Farenheidt – scalding hot!

camper conversion?
We’ve just bought a Renault T35 (old ambulance) for converting into a cheap and cheerful camper. The shower is going to be one of those solar showers that don’t need a pump or electricity. The toilet a portaloo. I’m considering adapting another solar shower to run the tap in the kitchen sink. But I still need electricity to power a small fridge and cooker/hob.
Is a leisure battery what I need?
How do I install it (Or other device)?
Will it charge from the alternator when the van is running?
If not what’s the best way to charge it?
Thanks x
You need a deep cycle battery and probably a higher output alternator. Get a kit that will have the parts and instructions on how to charge from van when hooked up and engine is running. Check with camper/van stores or auto supply stores for the kit you need.
If you have been considering having a solar heating system installed to help save money on energy bills, chances are you have put the thought to the back of your mind now that winter is here, thinking that solar heating only works during the months when the sun is shining.
But you would be wrong because solar heating is not just for summer! The belief that Solar Panels only work in sunny conditions is not a myth, it is just an outdated fact.
These days the panels used are powerful vacuum tube models that are unaffected by a lack of sun or cooler air temperatures. The vacuumed structure of the panels allows them to pull in whatever Solar Energy is available even on cold or dull days. They can absorb enough energy to provide hot water for eight months of the year and then assist with the running of an existing traditional system during the winter.
A solar heating system can save money on heating bills as well as helping to maintain the environment by using a natural source of power to assist traditional heating methods. The systems are considered very reliable by the majority of users says a survey conducted by the Department of Trade and Industry.
If you have put the idea of having a solar heating system on the back burner until the summer then reconsider! The system will bring advantages even in the winter, and the sooner it is installed, the sooner you could start seeing the cost benefits.
Contact your local Solar Heating Installation company and book a no-obligation survey. Choose one that is experienced and has been established for a number of years and if possible one that has been recommended to you.
Solar heating is not just for summer; it provides year-round benefits for your wallet and for the environment.

Does anyone know of a company in the St. Louis area that services Solar Heating Panels?
I bought a house that has solar heating panels on the roof but are currently not hooked up and was looking for someone to come look at them and see if the are in working condition and hook them back up.
Solar water heating systems use Solar Panels, called collectors, which for maximum efficiency are fitted on the roof of the house, in case of an apartment the side which receives the most sunlight. The basic function of solar water heating panels is to collect and store the heat from the sun and use it to warm water which is stored in a hot water tank.
Solar water heating panels use free heat from the sun to warm domestic hot water; it is not used in heavy industries as it is unable to provide the required quantity. A conventional boiler, immersion heater, or geyser may be used to make the water even hotter, or to provide hot water when Solar Energy is unavailable. Adding a heater is totally up to the discretion of the home owner; you may or may not find it necessary.
There are two types of solar water heating panels; they are evacuated tubes and flat plate collectors. Flat plate’s collectors can be fixed on the roof tiles or integrated into the roof. Both evacuated tubes as well as most flat plate collectors have a life expectancy of over 20 years, thus making them an good long term investment.
Solar water heating panels need around 5 square meters of roof and receive direct sunlight for the main part of the day. However, if you do not have a south facing roof and if you have enough space, you could install two panels, one facing east and one facing west – but this will make installation process more expensive and certainly more tedious. The solar panels don’t always have to be mounted on a roof; they can be fixed to a frame on any flat area that receives direct sunlight too.
The use of solar water heating devices is becoming very popular for many home owners in places such as France, Spain, Italy, Australia and the United States. One of the prominent reasons for the increase in popularity is attributed to government incentives for financing renewable energy projects, and also because of more efficient and affordable designs, are being developed every day. There are many benefits of using solar energy to provide with hot water, with the main benefit being the reduction in electricity bills.
