How does Mechanical Ventilation Heat Recovery (MVHR) work?
Step 1
Dirty, stale air is continually extracted from all the wet areas (Kitchen / Utility / W/C / etc) by the heat recovery unit, through unobtrusive white steel ceiling or wall mounted extract valves.
Step 2
This air then makes its way through a smooth bore anti static radial ducting system (75mm or 90mm), directly back to extract manifold by directly connecting each inlet/outlet there is zero leakage from there then back to the heat recovery unit via galvanised rigid ducting. Before being discharged outside, it passes through the counter flow heat exchanger giving up its heat to the cold fresh air coming into the house.
Step 3
The warm highly filtered supply air is then pre heated using the heat recovered from the extraction and re distributed (up to 96% efficiency) ensuring no cold draughts, which must be avoided.
Step 4
The supply air is now delivered through the smooth bore 75mm / 90mm radial ducting, through ceiling or wall mounted supply valves by the heat recovery unit, to all the habitable rooms (Lounge, Dining Room, Family Room, Study, All Bedrooms) resulting in whole house ventilation.
