What is the Genvex Combi?

The Genvex Combi 185 is a Passive House Institute certified combined heat recovery ventilation unit with air-source heat pump. 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 Genvex Combi can provide heat recovery ventilation at all times, even when the heat pump is delivering hot water, and has a COP (coefficient of performance) of 4.5. It is an all-in-one compact unit, meaning the system’s components are integrated. The air source heat pump heats the supply air and domestic hot water, prioritising the hot water.

The 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 311 control.

Where is the Genvex Combi Suitable?

Combi 185 S/LS is is particularly well suited to highly insulated homes and passive houses (of up to 300 square metres), where a high heat recovery rate and a low energy consumption are requested.

The 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 S/LS can deliver an air volume of up to appr. 325 m3/h at an external pressure of 100 Pa.
