Important Notes

1. 1

   A pool thermal blanket must be used. Pools without a thermal blanket, or pools uncovered for most of the day, could require heat pumps more than double the size calculated above. The higher the required pool temperature above ambient temperature, and the more wind over the surface, the greater the energy required.

2. 2

   Summertime use is defined as more or less September to March pool use.

3. 3

   A pool filtration pump run time (heat pump run time) of up to 12 hours per day might be required. For a shorter daily runtime the heat pump size should be increased.

4. 4

   A 15°C water temperature increase implies that if the unheated pool is currently at 16°C, the heat pump will be able to heat that pool to 31°C (16°C + 15°C).

5. 5

   Indoor pools also require a thermal blanket. Without one the heat pump will try to heat both the pool and the room, requiring significantly more power and causing high humidity and water condensation.

6. 6

   Inverter pool heat pumps only become more efficient than standard heat pumps when not running at 100% output power. Therefore we recommend going as large as the budget or power connection allows.
