If you are planning to build a new pool and want to save energy, water, and chemical use, as well as reduce equipment costs, consider the following:
- Site the pool to maximize solar gain during the times of year when the heat is most desired.
- If the site is windy, use wind breaks—fences, vegetation, etc.—to reduce convective heat loss.
- Select a pool cover that you know you will use. This may be a solar pool cover with a manual reel, an automated pool cover, solar rings, or a liquid pool cover.
- Select a filter that is appropriately sized for the pool.
- Invest in a variable-speed pool pump and program the control to run for only as long as is needed to filter the pool’s water.
- Include a solar pool heating system if you want increased comfort or to extend the swimming season.
- Address other energy uses around the pool. For example, LEDs can be used for in-pool and peripheral lighting.
If you already own a pool and are looking to make it more efficient, compare your pool to the pool described above. Could it benefit from a wind break? Are you using your pool cover regularly? What type of pump is used and how is it controlled?
