The DURATECH® heat pump has to be installed outside and will heat the pond all the year round. It draws its heat from the surrounding air. It works in the reverse of a refrigerator
The DURATECH® heat pump will even work with outside temperatures as low as -5°C.

CONSTRUCTED FOR DURABILITY AND LONGEVITY

Using advanced and high quality materials like PVC and “Duranium®” for the heat exchanger means it can resist to erosion from salt in the water.

Also, the “Duranium®” heat exchanger is oversized to improve efficiency and reduce noise.
