Mechanical Ventilation with Heat Recovery (MVHR)
| ENERGY SAVING TRUST ADVICE: | |
| Best Practice: | New Build |
|
Recommended: |
Major refurbishment |
Incorporates supply and extract ventilation in one system. Warm air is extracted from wet rooms via ducting through a heat exchanger before being exhausted to the outside. Fresh incoming air is preheated via the exchanger and ducted into habitable rooms.
Advantages:
- Controlled, preheated fresh air is provided throughout the house
- Polypipe MVHR appliances are SAP Appendix Q listed and Energy Saving Trust compliant
- Increases energy efficiency of the property by reducing heating demand
- Filters incoming air from outside
- Discreet installation
Mechanical Extract Ventilation (MEV)
| ENERGY SAVING TRUST ADVICE: | |
| Best Practice: | New Build |
|
Recommended: |
Major and minor refurbishment |
Continuous low rate extraction from wet rooms using a central appliance. Incorporates a boost facility to extract pollutants and supply fresh outdoor air at a higher rate.
Replacement air is drawn into the property using background ventilators.
Advantages:
- Easy to install
- Provides continuous 'low-level' background ventilation
- Simple operation
- Discreet installation
Exhaust Air Heat Pumps (EAHP)
| ENERGY SAVING TRUST ADVICE: | |
| Best Practice: | New Build |
|
Recommended: |
Major and minor refurbishment |
As with MEV appliances, exhaust air heat pumps continuously extract air from wet rooms. Heat energy is extracted from the exhausted air to provide space and hot water heating*.
* Check with the manufacturer that the appliance has the capacity to heat the property prior to installation.
Advantages:
- Provides a combined ventilation and heating solution
- High coefficient of performance (COP) compared to other heat pump technologies
