Residual heat as an engine for sustainable heat generation.The Circulair is a High Temperature heat pump. Ideal for central heating and hot tap water in stacked housing, care and utility. The Circulair runs on conventional central heating temperatures: 80 degrees centigrade supply and 60 degrees centigrade return.A small step for you, a big step for making your building more sustainable. Replace the central heating boiler with a high temperature heat pump. Use the heat from the ventilation air and leave the pipework and radiators unaffected, as well as the residents.The question is not whether you save energy, but how much. Circulair is an innovative transition technique in which residual heat from the ventilation air is reused for the heat demand. The principle is very simple: the exhaust air ducts are connected to the Circular unit on the roof. The High Temperature heat pump uses this heat as a source to heat the collective central heating water and hot tap water. Reduses Circulair is very suitable for sustainable heat generation in existing apartment buildings, care institutions and small utility buildings. It means saving a lot of energy without major interventions.Plug & playOne of the biggest opportunities that Reduses Circulair offers is the application for existing buildings. This is because the infrastructure of the existing central heating system is retained, so that major interventions are not necessary and there is no inconvenience for residents / employees. The Circulair is also good news for installers and contractors, because its clever design makes it easy to plug & play.
