Choosing A Heat Recovery Ventilation Unit
What is an MVHR Heat Recovery System?
The main advantage of a mechanical ventilation system is with heat recovery (MVHR) is to remove stale air from your house, recover a percentage of heat from it, add the heat to fresh air and pump it back into your house.
How does a heat recovery system work?
Inside your heat recovery unit is a air-to-air plate heat exchange cube. This cube is constructed from layers of heat absorbing material. The layers provide two separate air paths, one for extract air, and the other for supply air. The airflows do not touch each other, only the heat is thermally transferred from one air path to the other.
A quick couple of notes about heat recovery cubes.
Why choose a Heat Recovery Ventilation System?
The more insulated (air tight) your house is, the more you will benefit from having mechanical heat recovery ventilation. A well insulated house without ventilation will generate a huge amount of condensation and create a terrible indoor environment. Installing a heat recovery system will not only eliminate condensation build up by extracting stale air from your house, it will recover the heat from the stale air and pump fresh heated air into your house, vastly improving your indoor environment.
Which Heat Recovery Ventilation Unit Do I chose?
Heat Recovery Units are generally chosen based on how many wet rooms you are extracting air from. Here is a list of the common sizes:
