Sondex HW

Small Wallmounted District Heating Unit for Hot Domestic Water:

Sondex HW is an instantaneous water heater for one-family houses and apartments. It’s space-saving and is easy to install in e.g. cupboards, technical rooms or in utility rooms.

The unit is supplied with our own highly efficient brazed heat exchanger, in which the sensor of the thermo-valve is placed securing an exact control of the water temperature, a minimal wait for the hot water and calcium control.

Sondex HW refrigerates the district heating water effectively and grants a big quantity of hot water, which is heated successively, while tapping.

The temperature of the hot water is controlled by a thermo-valve, factory set at 50-60°C.
This setting is consumer as well as environment friendly, as the temperature is kept below the critical limit for calcium deposit in the domestic water.
