The drinking water heating pump SensoTherm BTW 300 from Brötje is an ecological product with a high quality. At the same time, it offers ease of use and a good functionality. The pump can heat up drinking water up to 62 °C without an immersion heater. By using the existing room air reservoir, it warms up the drinking water at a low cost. An integrated PV contact takes care of the additional private use of power from photovoltaic systems. The SensoTherm BTW 300 can be operated in circulatory air operation as well as in extraction mode; in the circulatory air operation, it dehydrates the room at the same time. The operation unit can be removed from the pump and mounted to the wall – thus it adapts to the requirements of different rooms.
