Heat Recovery Ventilators provide an energy efficient way to bring in fresh filtered air while removing stale air.
A heat recovery ventilator (HRV) brings in fresh air from the outside, preheats the incoming air during the winter and precools the incoming air during the summer. It can provide clean fresh air every day while helping to keep energy costs low.
The American Lung Association recommends HRVs and sealing of air leaks to protect your health while conserving energy.
Tight buildings reduce energy costs by keeping in the heated or air conditioned air. But tight buildings without adequate ventilation trap humidity and pollutants so they feel “stuffy”, aggravate allergies and cause general discomfort for you and your family. Moisture damage to windows and other parts of the building shell can result when humidity is too high.
Heat recovery ventilators have long been popular in Canada and are becoming popular in the USA. In fact, Canada has a national ventilation law. In 1992 there were more than 125,000 units sold here.
