About Mechanical Ventilation & Heat Recovery (MVHR)

It is important to keep the air fresh and healthy and to avoid condensation and damp in an airtight dwelling. An MVHR system will do this for you.

It works by extracting warm air from the kitchen and bathrooms and retaining that heat to distribute around the property. It can lead to reduced heating costs and a healthier air quality.

The vents on the system are connected to a central fan unity with a heat exchanger and is usually only fitted to new build properties, but it is possible to retrofit in some circumstances.

You can see a working display of an MVHR system in our Eco-Centre.
