Make a Swimming Pool Solar Heater


Using the sun to heat your swimming pool is one of the most practical applications of free solar energy. You can use a solar water heater to extend your swimming season and retain the pool warmth overnight without having to think about the costs. Swimming pool solar heating systems can heat a large amount of water each day, and are quite capable of keeping the pool temperature at 80 to 85 degrees even in moderate sunshine.

Fitting a solar pool heater is also a good way of adding value to your home.

Buying a ready-made solar water heating system could cost you anywhere from $2,000 to $4,000 depending on collector size and installation costs. But you could build your own swimming pool solar heater for an average-sized pool for under $200, including materials and an extra recirculating pump.

Swimming pool solar heaters are plumbed in to your existing filter system. While the filter is working during the day the pool water is passed through the solar collectors and returned to the pool. It is possible to have a system without any moving parts, such as a recirculating pump, but this is governed by the daily sunshine activity locally.

The solar collector panels are typically installed on a roof in a position to receive the maximum amount of direct sunlight. Ideally the collectors should face the mid-day sun and be at an angle equivalent to your latitude minus 10 to 15 degrees. Several factors will influence the size of the collector panels, but it will be at least 50% of the pool surface area. Increase this to 75% if the collectors are laid flat or facing west. It is not unusual for the collector area to be the same as that of the pool when the site is shaded badly or exposed to strong winds. Because solar collectors tend to take up a lot of space, it is often better to mount them on a frame on the ground or even a suitable fence.

There are several factors which can influence a solar heater installation, including:

  • Weather and sunlight availability.
  • Building codes and safety regulations.
  • Size of the pool.
  • Length of the swimming season.
  • Required pool temperature level.
  • Solar collector efficiency.

You really need the help of an expert to design your swimming pool solar heating system when considering these factors, because only a suitably-qualified person will have the necessary expertise to give you the right plans for making your swimming pool solar heating system work properly for you.

It is very easy to make and fit your own swimming pool solar heating system and you need no special skills or tools. Your local hardware store should have all the necessary materials. But, as always, there are experts that will make your job easier and safer, and the project planning stage much more complete. We have no hesitation in recommending one group of professionals who have produced a simple set of plans and a comprehensive set of clearly illustrated instructions to guide you throughout the build in making your solar swimming pool heater.
