HRV - Heat Recovery Ventilation

Heat Recovery Ventilation systems are an excellent way of bringing in fresh air and removing stale humid air. HRV systems rated for 1500 square feet cost about $700 - $1000 (not installed). HRV systems operate by replacing the exhausted air with fresh outside air. The outside air is warmed up by going through an heat exchanger which is heated by the warm air being exhausted. HRV's can be installed in any home.
