    This video shows you step by step on how to build a Heat Recovery Ventilator (HRV) that can expel stale indoor air to the outside, and draws in fresh air from outside to be distributed throughout the home.A Heat Recover Ventilator (HRV) is integrated into the duct work in a home, usually located near the furnace.These are very efficient, recovering and transferring as much as 80 percent of the heat energy contained in the outgoing air. So they increase the supply of fresh air for your home but also recover much of the heat energy you’ve already paid for thereby saving money on heating bills.
