MVHR – Mechanical Ventilation with Heat Recovery

MVHR is a whole-house mechanical heating and ventilation system designed to supply fresh air and extract stale air continuously from the property.

The way MVHR works is to pump clean, fresh air into the system via ducting, whilst extracting stale, moist air from the kitchen and bathroom. The heat from the moist air is stored and filtered and the excess is expelled through the chimney whilst the clean air is filtered and warmed, then passed to the living and bedrooms.
