Domestic hot water module for hygienic drinking water
Comfortable domestic hot water technology for the domestic hot water preparation
The PAW Friwa modules heat potable water comfortably and hygienically operating on the principle of a flow-type water heater. With various nominal diameters, they are optimally adapted to your needs. In addition, the powerful
plate heat exchanger heats the water only if necessary. Unlike conventional domestic hot water tanks, the water in our Friwas is not used for energy storage and is not stored as domestic hot water for hours or days. The energy
necessary for heating the domestic water is provided by a buffer tank which can be heated via various systems.
This can be solar systems, solid fuel boilers or conventional oil or gas boilers. Also, domestic hot water modules and heat pumps can be efficiently combined
with each other. The Friwa modules are also optimally suited for an application in combination with a solar thermal system. This means, the cooling of the heating water in the efficient plate heat exchangers improves the
efficiency of the solar circuit. Thanks to the cold return, the medium temperature of the solar circuit can be reduced.
Advantages of the PAW domestic hot water module "Friwa":
High energy utilisation due to high-efficiency pumps
Domestic hot water module available with or without circulation
The types FriwaMidi, FriwaMaxi and FriwaMega are cascadable. To cover larger withdrawal flow rates, such as in the hotel industry or in hospitals, the basic module without a circulation line can be extended to a double,
triple or quadruple cascade by using a pipe set.
