Our general experience is that solar heaters tend to boost pool temperatures by about 2-3°C and they do extend the swimming season.
important to understand that the Pooled Energy system only controls your solar
heater operating times ...that is, it turns the heater ON and OFF. There may not be enough solar heat available
to reach the desired temperature. The heating derived from the sun depends on
the weather, the air temperature, the time-of-day, the size of your solar
heater, its orientation and its efficiency.
If you want more reliable temperature management, you will need to purchase a gas or heat-pump, booster heater. These can also be managed by the IPC but please discuss sizing, cost and integration with us.
