for decentralized hot water
The domestic hot water station BM-F is used as a home station for the multi-storey and single-family homes.
Decentralized hot water production:
The domestic hot water is heated only during the request through a stainless steel plate heat exchanger in the flow principle. In heating systems with buffer, the heating water, according to the pressure loss during the dispensing process,
by means of a central controlled circulating pump pumped through the heat exchanger.
The station can be connected directly to a secondary district heating network or CHP system.
Proportional controler PM-TD with thermostatic adjustment and internal differential pressure control, for quantity and temperature-dependent control of DHW heating.
The proportional controler ensures a constant DHW temperature regardless of the quantity taken, the heating water temperature or the tap intervals.
A universal mounting distance 110 mm for surface water meter and a universal mounting distance 110 mm for heat meters to 1.5 Qn are integrated in the distribution cabinet.
The flow temperature control is performed by a thermostatic control valve. The adjustable control range is between 30-60 °C, with maximum temperature limitation. The factory setting is 45 °C.
(Optional can be installed a control valve with actuator for outside temperature regulated controls.)
By default, a circulator with 130 mm length is assembled. Alternatively, a high-efficiency pump (energy-efficiency class A) are mounted.
When overheat protection acts a safety temperature limiter, the circulating pump switches off when exceeding the maximum temperature.
