Question 1

How do I size a heat pump for my swimming pool?

Accepted Answer

Enter your pool length, width, and depth (or volume directly), select your climate zone and whether the pool is indoor or outdoor, set your target temperature, and indicate if you use a pool cover. The calculator estimates heat loss and recommends the correct iSPA model with estimated monthly running costs.

Question 2

What COP do iSPA pool heat pumps achieve?

Accepted Answer

iSPA pool heat pumps achieve COP ratings from 5.98 to 7.52 at standard test conditions (A27/W27). Under optimal conditions COP can reach up to 14.05.

Question 3

Does using a pool cover reduce heating costs?

Accepted Answer

Yes, significantly. A pool cover reduces evaporation losses by 40-50%, which is the largest source of heat loss in most pools. The calculator adjusts its recommendation based on pool cover usage.
