Swimming Pool Energy Saving Tips
It is important to note that a heat pump will not heat a pool as fast as a large gas or electric pool heater. If the pool water is
allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it
is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan
to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the
temperature setting of the control several degrees to minimize energy consumption.
Pentair offers the following recommendations to help conserve energy and minimize the cost of operating your heat pump
without sacrificing comfort.
1. The American Red Cross recommends a maximum water temperature of 78° F. [25° C.]. Use an accurate pool
thermometer. A difference of 4° F. [2° C.] , between 78° F. and 82° F. [26° C. and 28° C.], will significantly increase energy
consumption.
2. Carefully monitor the water temperature of your pool in the summertime. You can reduce heat pump usage due to warmer
air temperatures.
3. During the winter or when on vacation for longer than a week, turn off the heat pump.
4. Find the proper setting on the heat pump temperature control and use the Keypad Lock function to discourage further
adjustments.
5. Set the pump time clock to start the pump no earlier than 6:00 AM during the pool-heating season. This is the time when
nightly heat loss balances.
6. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or
fencing.
7. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat
loss, conserve chemicals, and reduce the load on filter systems.
