Heat Recovery Ventilation or HRV is forced ventilation which recovers some of the otherwise lost heat. 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.
