As we have learned how to seal up our homes to keep out cold air in winter and hot air in summer, we have encountered the problem of getting fresh air into the home. When houses were drafty, had no insulated windows, were poorly insulated and weatherstripping was never used, fresh air was not a problem. Plenty was coming in the home. Trouble was, it was costing more to provide the heating or cooling. Tightening up the home reduced those costs but created bad inside air.

Fresh air intakes were the answer to the situation. With fresh air movement controlled, we could move out stale, moist air and bring in fresh air. This created a better balance. Outside air is, however, just as cool in the winter and warm in the summer as it was.

So a method was developed to allow the warmed, outgoing air to heat the incoming fresh air. That method is accomplished with heat recovery ventilators. Simply put, heat recovery ventilators act much like automobile radiators. As the needed fresh air comes in, it can be heated through an exchange system up to an amazing 85 percent by the outgoing stale air.

This saves energy by utilizing air that has already been warmed and heating incoming air. As the outside air goes into heat recovery ventilators, it is kept separate from outgoing air. Only the heat transfers; the pollutants and humidity go out. Incoming air becomes warmed  or cooled and the heating and cooling system does not have to work as hard.

Colder climates, such as ours in  Massachusetts, get the most benefits from heat recovery ventilators due to longer winters than more southern climates. Energy savings can often be substantial by using the exhaust air to heat the fresh air.
