Pool heat pumps
Understand COP, inverter operation, cold-weather performance, sizing and installation before comparing current pool heat pumps.
Plan the decision before comparing equipment
A heat pump is usually a temperature-maintenance decision before it is a brand decision. Begin with the lowest air temperature in which you expect it to operate, the pool’s exposed surface area and how consistently you will use a cover. Then compare manufacturer performance tables at conditions resembling your season—not only the warm-air rating printed most prominently.
