Up to 93% Heat Recovery
MHRV heat exchangers reclaim thermal energy from extracted air, dramatically reducing heating load.
Asthma & Allergy Safe
G4 and F7 filters scrub pollen, mould spores, and diesel particulates before air enters your home.
Clean, Quiet Installation
Dust-free drilling, rigid insulated runs, and premium European units that operate at a whisper.
The Science Behind the Savings
At the core of every MVHR system is a cross-flow heat exchanger. Outgoing warm stale air and incoming cold fresh air pass through a compact core — side by side but never touching. The warm air heats the cold air before it reaches your rooms, recovering up to 93% of the heat that would otherwise be lost to the outside.No Mixing — Only Heat Transfer
The two air streams remain completely separate. Only thermal energy crosses the boundary — never moisture, odours, or contaminants from stale air.
Fresh Air In, Stale Air Out
Cold outdoor air enters the exchanger, gets pre-warmed, and is quietly distributed to living spaces and bedrooms. Stale air from kitchens and bathrooms is expelled outside.
Continuous and Silent
The system runs 24 hours a day at low speed — maintaining clean air quality without any fans you notice or windows you need to open.
