Product Description
Mechanical Ventilation/Heat Recovery (MVHR). This heat recovery unit is designed for the energy efficient
ventilation of houses and similar dwellings, conforming to the latest requirements of the Building Regulations
document F 2010.
The unit is designed for continuous 24-hour extract ventilation of stale moist air from bathrooms, toilets, utility
rooms and kitchens. As the stale air is extracted, a heat exchanger within the unit transfers up to 93% of the
extract air’s heat, into the supply air entering the bedrooms and lounge. This provides significant energy
recovery, reducing household heat costs, and providing the optimum comfort conditions.
In addition, some models will have features that maintain a constant airflow independent of the blocked filters.
