How a Heat Recovery Ventilation System Works
Part I –Improving the Air Quality of your Home
> Two fans are installed.
> One fan draws the warm stale and polluted air from the living areas of your home through the HRV system to be released outside.
> The second fan draws a continuous stream of cool fresh air in through the system to be distributed throughout your home.
Part 2 -Saving you Money
> As the warm air being expelled moves through the HRV system and passes the cool fresh air being drawn in, heat is transferred from the outgoing stale air to the incoming fresh air.
> HVRs can recover up to 70-80% of the heat in the exhaust air.
