roduct description
VP18 is a ventilation unit with active heat recovery that also produces domestic hot water.
VP18 is intended for air volumes of up to 425 m
3
/h at 100 Pa external counter-pressure.
The ventilation draws humid and vitiated air out of the dwelling via bathroom, lavatory, kitchen and
utility room. It introduces fresh air into living areas such as living room, bedrooms and study. Cold
outdoor air gets heated via the heat pump by warm extract air.
The integral heat pump utilises energy in the extract air to produce domestic hot water. The hot water
tank has been fitted with a 1.5 kW supplementary electric heater that will help heat up domestic water
when hot water consumption is high.
In the winter, the heat pump can be used to heat the supply air during periods in which no domestic hot
water is being produced. The supply air can be heated up to 34 °C.
As the heat pump is reversible, in the summer it can be used for cooling supply air. VP18 can cool
supply air by up to 10 °C. However, it does not function as an air condition unit as it operates with
relatively low air exchange. Cooling the supply air removes humidity from the indoor climate. This
provides comfort for users of the dwelling, even at high indoor temperatures. VP18 can cool and
produce domestic hot water simultaneously. Cooling of supply air is therefore essentially "free of
charge".
