Whilst buildings are now made more airtight than ever before, this consequently results in lower ventilation.
Mechanical Ventilation Heat Recovery is a system which employs a cross flow or counter-flow heat exchanger between the inbound and outbound air flow providing fresh air and improved climate control.
The (warm) stale air from the wet rooms and the (cold) fresh air from the exterior both pass through a heat exchanger, in opposite directions and without mixing.
The heat contained within the extract air is transferred to the incoming fresh air, which is then introduced back into the living areas of the building. Heat Recovery Ventilation does not produce heat, but minimises the amount of heat which would otherwise be lost through ventilation, with degrees of efficiency varying between 90 – 95%. In doing so, it reduces the amount of heat that needs to be produced to keep a house warm.
