Application:Our DHW units FW-E 60 are heating the domestic water centrally and are supplying it via hot water pipeline to the domestic water tapping points. A buffer tank is necessary in order to provide the required heating water quantity for heating the domestic water! The DHW water is only heated when "Just in Time" is requested. There is no storage of hot water!
Water heating:The DHW water is heated in the fl ow-through principle only during the request via a stainless steel plate heat exchanger. A special heat exchanger design allows high tap rates and a low return temperature to the buffer tank.
High effi ciency pump:The DHW volume fl ow (speed controlled) is delivered by a high-effi ciency pump from the buffer tank to the plate exchanger for the heating of water.
Control function:The central control element is the electronic controller. This ensures a constant domestic hot water temperature.
Sensors:Fast and very precise control processes are made possible by the use of state-of-the-art sensors. A fl ow sensor according to the vortex principle, determines the fl ow rate and the hot water temperature. Accurate and fast reacting PT-1000 temperature sensors measure the temperatures of: cold water, buffer tank fl ow and circulation return.
Housing:Stylish EPP insulating housing with design front panel.
Circulation module Z3 / Z4 (optional):A drinking water high-effi ciency circulation pump is controlled intelligently (according to pulse, time and temperature) and speed-controlled by the electronic control system (integration on-site).
