Why is my PoolMaster Heater not heating the pool?
- TTyler HamiltonJul 28, 2025
If your PoolMaster Solar Heater isn't heating the pool, ensure water is flowing through it by checking the flow at the pool return. For optimal heating, the heater needs full sun exposure for about 10 hours daily. Using a solar or pool cover at night can help minimize heat loss. Also, consider that your pool size might need more Solar Heaters.
