Our user-friendly, set-and-forget controller allows you to run the heater along with the existing water filtering schedules of your pool or spa.

How does it work?
The Calitec Pool/Spa Heat Pump Heater must be installed after the filter and circulation pump. The heat pump's flow switch detects water circulation and activates the heater when the water temperature is below the set point. Once the desired temperature is reached, the heat pump turns off. Similarly, when water circulation stops, the heat pump automatically shuts down.
