Mechanical Ventilation with Heat Recovery
Fresh air without the heat loss
About Mechanical Ventilation with Heat Recovery
Mechanical Ventilation with Heat Recovery (MVHR) systems provide constant fresh air throughout your home while recovering up to 95% of the heat that would otherwise be lost through ventilation. Essential for well-insulated, airtight homes.
Key Benefits
Heat Pump Costs (After BUS Grant)
MVHR works best in airtight homes with heat pumps. These heat pump costs show the savings from a complete system.
| Property | Heat Pump Size | HP Net Cost | Annual Running |
|---|---|---|---|
| 1-2 bed | 5-6 kW | £0 - £2,500 | £610 - £720 |
| 3-bed semi | 8-10 kW | £500 - £5,500 | £610 - £720 |
| 4-bed detached | 10-12 kW | £3,500 - £10,500 | £610 - £720 |
Helpful Guides
Our Installation Process
Ventilation Design
We calculate air change rates for every room and design a ducting layout that ensures optimal airflow distribution.
Unit Selection
We select an appropriately sized MVHR unit based on your home's volume, occupancy, and airtightness level.
Installation
We install the MVHR unit (typically in a loft or utility room), run ducting to all rooms, and fit supply/extract valves.
Commissioning
We balance airflow rates in every room, set up boost controls for kitchens and bathrooms, and commission the heat recovery function.
