A Wilnow solar heating system can be used to heat a small domestic pool or an Olympic-size public pool, and everything in between.

If you are in the process of designing or building a new pool then now is the ideal time to consider installing a solar thermal system. If you already have a pool we can simply retro-fit the system without the need to change your existing heat sources.

A typical solar pool heating system will consist of four key components: Solar collectors, pipe work, heat exchanger and control system. The specification, location and method of installing the parts will vary depending on the particular application.

A southerly-facing pitched roof or wall, or a flat roof, are ideal locations for solar collectors to be mounted on. Collectors can be installed on an east or west-facing but the total collector area will need to be increased to compensate for the lower energy levels.

Shading, aesthetics, roof condition and accessibility will all be considered when selecting a position for the solar collectors.

Once the pool's energy demand has been estimated (based on pool design, operating temperatures, usage and location) and the collector location identified, the number of collectors required can be specified. As there is a fixed amount of solar energy available to the collectors, the larger the collector area the more energy will be absorbed.

If the area of collectors installed is too small they will not be able to heat the pool to a usable temperature. If the area of collectors installed is too large, not all of the energy available will be used and therefore part of your investment will be wasted.
