There are many different uses for solar energy. One of the most commonly perceived uses is to generate electricity directly with the use of photovoltaic panels. However, the truth of the matter is, this is not the most efficient way to capture solar energy is through taking advantage of the solar thermal energy the sun produces. Some power stations now use solar thermal energy to generate electricity, however in this case we are more interested in capturing solar energy directly for heat, with solar pool heaters. In the past, when energy was cheap, most consumers used electricity or gas to heat their pool. However, those days are gone, and with concerns over global warming there prices are set to increase year on year. So how do you heat your pool, after all a cold pool isn't half as inviting. This is where solar thermal energy comes in, and capturing that energy to heat your pool to a warm ambient temperature. One form of solar pool heaters, are solar covers. These basically look similar to bubble wrap, just on a much larger scale. The cover allows solar energy into the pool, however the cover has insulating properties which then keep that heat within the pool. Solar covers are great, they help to keep the pool clean and also generate some heat. However, to get the pool to an ideal temperature, more heat is required. Solar thermal energy can do this, but in a more concentrated form such as a solar water heater.

Solar water heaters capture more solar heat within the smallest space possible, amplify the heat from the sun and insulating against heat loss. Using a solar water heater will provide you will all the heat you'll need.

The video below is of an example of a solar water heater which would be ideal to be used a pool heater. This particular design is known as a passive solar water heater. The video shows how simply the solar heater can be produced and put to good use immediately. The parts required to build a solar water heater can be sourced from any local hardware store.

How To Build a Pool Solar Water Heater

One of the first parts to purchase is a suitable water storage vessel, the tank should be black to absorb as much solar energy as possible. The volume of the tank will be calculated on the size of swimming pool you wish to heat. This is where the heat is captured.

Is It Practical To Make You Own Heater?

Building solar pool heaters is a realistic project for anyone with even only a basic knowledge of DIY skills.
