Heat pumps for
outdoor swimming pools

  • Heat pump for outdoor swimming pools HPP heat pump

Extend the swimming pool season with Dantherm's new HPP heat pumps, specifically designed for heating small and medium sized outdoor pools and spas.

Pool heat pumps operate by taking the heat from the surrounding air and use it to heat the pool water.

Dantherm's HPP heat pump can produce up to five times the energy it consumes. The low energy consumption coupled with high heat production makes the HPP heat pump an environmentally friendly way to heat swimming pool water.

HPP heat pumps are designed to work all year round at air temperatures above 3°C. In this way you can extend the pool season by several months.


The HPP heat pump has an integrated controller with a touch-screen user interface. The basic functions are: 

  • Heat pump ON/OFF
  • 24-hour time clock
  • Timer ON/OFF
  • Parameter adjustment
