How does MVHR work?

In wet rooms, such as kitchens, bathrooms, W.C’s and utility rooms, extract points are installed to remove the warm, moist air. The air that has been extracted, before it is exhausted to outside, it is used to temper the incoming air into the building via a heat-exchange block within the unit. The fresh, filtered, pre-warmed air is then supplied into the habitable rooms such as the bedrooms and living room. The heat exchanger can transfer up to 92% of the heat recovered into the fresh incoming air.

How are the ventilation rates calculated?

Typically, the minimum ventilation rate is calculated by multiplying the total internal floor area by 0.3 l/s/m². The boost rate is calculated by assigning the following vent rates to each wet-room, and then adding them together. (kitchen 13l/s, bathroom 8l/s, utility 8l/s, WC 6l/s)

What to do if my home gets too warm?

During the summer months, there is a summer bypass system. This means that the intake air will not be tempered as it is diverted around the heat exchange block. This can help in reducing the indoor temperature.
