The Combi is a Combinated heat recovery ventilation appliance. It is equipped with high efficient supply and extract air fans, and a counter-flow heat exchanger with an efficiency of up to 95%. The Combi includes an automatic bypass for passive cooling.
The air source heat pump heats the supply air and domestic hot water, prioritising the hot water. The enamelled steel hot water cylinder can as an option be connected to a second heat source, eg. solar panels.
The unit is delivered with a F7 supply and G4 extract air filter and Optima 312 controller.
Combi 185 BP is suitable for dwellings, where a high heat recovery rate and a low energy consumption are requested, while energy of the extract air is used to heat the supply air and the domestic hot water. The energy is recovered in the counterflow heat exchanger first and then the heat pump uses the residual energy. Combi 185 BP can deliver an air volume of up to appr. 325 m3/h at an external pressure of 100 Pa.
