Domestic hot water

Comfortable domestic hot water technology for your needs!
Our domestic hot water modules Friwa heat potable water comfortably and hygienically operating on the principle of a flow-type water heater. The powerful plate heat exchanger heats the water only if necessary. Other than in conventional domestic hot water tanks, the water is not used for energy storage and is not stored as domestic hot water for hours or days.

Easy preparation of domestic hot water
The energy necessary for heating the domestic water is provided by a buffer tank which can be heated via various systems, such as solar systems, solid fuel boilers, conventional oil or gas boilers or heat pumps. In addition, the Friwa modules are very well suited for an application in combination with a solar thermal system.
