Flexit WH4 is a combined system - it combines four system units to provide ventilation, hot water and underfloor heating to a building. It is capable of air exchange up to 370 m3/h (operating point: 240 m3/h). 

The heating capacity of the unit is up to 4 kW, combined with a 3 kW electric shroud for additional hot water support, making it most suitable for small, energy-efficient new buildings that do not require high heating output and have limited space for technical space. Unlike standard air-to-water heat pumps, it does not require a separate outdoor unit - all units are located indoors.

Main advantages:

• The unit continuously exchanges air at your desired temperature throughout the building;
• A complete plant that combines everything needed for heating and ventilation of the building, requiring less consumption;
• An environmentally friendly and future-ready CO2 reagent;
• Helps to keep the room cool on hot summer days by using the cold return air to cool the supply air. Outdoor air is also used to cool the room at night, when the indoor air is warmer than the outside air;
• High tank capacity of 197L, able to produce hot water even during heating. The water is heated to +65°C only by a compressor;
• Controlled by the Flexit GO app.
