Heat Recovery Ventilation or HRV is forced ventilation which recovers most of the heat that would otherwise be lost in the vented warm air. A crossflow heat exchanger is used to transfer heat from outgoing air to incoming air.
- HRV provides fanned ventilation at much lower run cost, as much less heat is lost to the outdoors.
- HRV units may be diy constructed.
- HRV can be combined with earthpipe warming and cooling.
- HRV is often combined with filtration to reduce airborne dirt ingress, reducing the amount of housecleaning required.
