MVHR in your home
A heat recovery system provides a constant supply of clean fresh air into your property without losing heat by extracting moisture and stale air.
It is essential to ensure that the system receives the correct ongoing servicing and maintenance to enable it to function properly for the health of the occupants, the fabric of the building, the minimizing of running costs and to save heat within your property.
The Important Job Of A Heat Recovery System
Air Quality
Maintain a good level of indoor air quality for you and your family.
Environment
To contribute to a comfortable indoor envrionment all year round
Reduced Heating Costs
To help reduce your heating bill by re-using otherwise lost heat
What Is It And Why Is It There
A centralised fan unit is situated in your property which draws the stale moist air from your bathroom, kitchen, WC, utility & en-suite rooms removing it from the property through the circular grills located in the ceiling. The extracted air passes through the centralized fan unit's heat exchanger, allowing the supply air coming into the property to recover the heat being extracted.
The air is moved around the property at a low level continuously 24 hours a day, 7 days a week. Your home is ventilated without the need to open windows which can let in noise, fumes and can compromise security.
It will prevent the build-up of moisture in the house, remove steam/condensation and odours during bathing and cooking and prevent black mould forming on the walls, behind cupboards etc. It will also stop the dampness that you can get in your cupboards and wardrobes on close and furnishings caused by poor ventilation.

The importantance of Heat Recovery
Operating Your System
Your MVHR system is designed and installed to work with little to no intervention or operation. Once commissioned and set up correctly it will provide balanced supply and extract to your home.
The low ventilation continuous airflow is calculated based on the size of your home and occupants with a boost facility operated by a manual switch, light switch and some operated by in-built humidity sensors.
How Much Does It Cost
Your system uses very little energy to operate , it is not a heating system, it recovers upto 95% of the heat within the air in your home and will lower your heating costs as you are not wasting energy heating your room to open windows and expel warm air.
Keep Your System Working
Filters should be cleaned by hoovering every 60-90 days depending on outside environmental conditions. Replace filters every 12 months and have a cleaning service.
If you notice a lack of extraction, dust and dirt around the bedroom and living room grills, noise from the unit and poorer air quality then it is time your system is serviced.
