MVHR
Provides fresh filtered air into a building whilst retaining most of the energy that has already been used in heating the buildingWith Building Regulations moving towards better-sealed homes, the need for mechanical ventilation is growing. Moving air around the home and enabling good air change rates is critical to maintaining a comfortable and healthy living environment. If air movement is stifled, your home will become stuffy which, in turn, can lead to health problems (asthma, lethargy and so on).
ABOUT MVHR
MVHR extracts warm stale air from bathrooms, toilets, utility rooms and kitchens which then passes through a heat exchanger unit before being expelled to the outside atmosphere. At the same time, it draws fresh air from outside which passes through the same heat exchanger and therefore warming it up to be delivered as warm fresh air to living or working areas.
In effect, recovering heat energy rather than letting it go to waste.
The installation of MVHR in a building will also affect the heating system design. One of the effects of heat recovery ventilation is to equalise the temperature throughout the building. Therefore it is important to prioritise the heat supply to the rooms that should be warmer.
If the building is of a sufficiently high standard then it might be only necessary to put heat directly into certain rooms. In contrast with conventional building standards, in very low energy and Passivhaus buildings, it can be pragmatic choice to put all or some of the heat requirement in through the ventilation system. Again, it is vital that the system is designed with a clear understanding of the design requirements when ventilation air heating input is to be considered.
