MECHANICAL VENTILATION HEAT RECOVERY (MVHR)

Mechanical Ventilation with Heat Recovery (MVHR) is the next stage to make a home comfortable. With building regulations continuously improving a buildings thermal efficiency by pushing for more insulation, better glazing and air tightness, a home should still be able to breath.

​

The benefits of MVHR should not be underestimated:

 - A Rated units

 - Extraction of warm, moist air from bathrooms, kitchens, utility rooms & WCs

 - Supply of pre-warmed filtered air to living areas and bedrooms

 - Full summer bypass to prevent over heating in the summer

 - Automatic and manual boost functionality for get rid of unwanted smells
