In this installation by Green Building Store, the MVHR unit is hidden away in a kitchen cupboard and the ducting is left on display as an attractive contemporary design feature
1 How does mechanical ventilation and heat recovery tech work?
Wendy: MVHR offers year-round, whole home ventilation that removes stale air, condensation and pollutants, whilst recovering heat that you can pump back inside. Moistureladen air is extracted from wet areas, such as kitchens and bathrooms. The warmth from this is recovered via a heat exchanger, passed onto a new filtered supply and put into the rooms in your property, creating a healthier living environment for the household. It significantly improves the indoor air quality and reduces energy usage.
Clarissa: It means you recover up to 95% of the heat you would otherwise lose, perhaps saving a third on heating bills and your lungs the trouble of filtering pollutants.
2 Why is MVHR important in new build properties?
Stefan: Ventilation is critical for airtight buildings. In fact, the risk of black mould triples when dwellings are being efficiently insulated and made more airtight.
