A pool heat pump warms your water by pulling heat from the air around it, not by making heat. It uses electricity to run a fan and a compressor inside a sealed loop. You don't burn fuel or use heating coils directly. Instead, the system moves existing heat from the outside air into your pool water.
The standard rule for pool heat pump sizing is 0.31 kW per m³ of water for summer-only heating. Extended seasons or colder climates require 0.39 kW per m³.
