VGU 250 is an extract ventilation unit with active heat recovery. It is typically used in single-family dwellings for production of domestic hot water.
The unit extracts warm, humid air from e.g. kitchen, bathrooms and utility room. The energy from the extracted air is then recycled for production of domestic hot water. This process is so efficient that the unit only consumes 1/3 of the energy used by traditional water heaters.
The unit contains a 230 litre hot water tank and has an extra heating coil. This can be combined with solar panels, oil, gas, district heating or other forms of fuel and thereby increase the production of domestic hot water.
The VGU 250 unit has a simple control system that is easy to operate.
