Energy efficient homes of today should have high levels of insulation, built as close as possible to airtight standards and contain a central ventilation system with heat recovery.
The AXCO range of mechanical ventilation systems with heat recovery (MVHR) are designed to recover up to 95% of the heat normally lost through open windows, trickle vents and other break-out points i.e extractor fans in a building structure.
Fresh air is continuously drawn into the home via a low energy heat recovery ventilation unit, located in the roofspace/utility area of the home. The ventilation unit filters the incoming air and removes any pollutants and insects. once it has been passed through the heat exchanger within the ventilation unit , the warm, clean fresh filtered air is distributed around the home, using a series of routed ducts to each habitable room (i.e. living room, bedroom etc…)
Air from the wet rooms (i.e. bathrooms, kitchens, wc’s and utility areas) are continuously extracted and filtered back through to the ventilation unit, where the heat from this air is transferred into the fresh incoming air.
A standard extract fan will vent warm air to the atmosphere. The property will then have a higher energy efficiency rating and comply with current building regulations. This is calculated by using the SAP appendix Q.
