MVHR systems
An MVHR (Mechanical Ventilation with Heat Recovery) unit is a system providing fresh filtered air into buildings whilst retaining 95% of the heat energy already used in the building.
Air is taken from kitchens, bathrooms, and utility rooms and the outgoing air passes through a heat exchanger, transferring its heat to the incoming fresh air.
If something's not right and we're responsible, you can raise a repair in your online account, under the 'Manage repairs' section. You'll find a section for MVHR under 'Renewable energy'.
You can also raise a repair through our chatbot or by giving us a call on 0800 652 0898. If your repair is an emergency, please call our out of hours team on the same number, who will be available day or night.
If we're responsible for your MVHR we will:
- Service your unit every 5 years
- Replace the filters when needed
To help get the most out of your MVHR we recommend you:
- Keeping your MVHR always running as this is when it works best
- Wiping down the intake and extract areas with a damp cloth to help remove any dust build up
