Keeping Energy Efficient Using a Heat Recovery Ventilator in Your Nashville Home So you’re livin’ large in a northern zone, i.e., anywhere northwest of the Florida panhandle. Ok… you’re maybe slightly further north. And you’ve heard how beneficial indoor air ventilation can be for indoor air quality. But, you think to yourself, “won’t all my warm air just float away if I expand my ventilation?” That’s where the Heat Recovery Ventilator comes in. With two fans set at opposing sides of your house—one for blowing in fresh air, the other for blowing out stale air—the heat recovery ventilator directs air through many ducts past the heat exchanger. Now the heat exchanger is similar to a cop at a checkpoint, checking to see if the stale air contains heat. If there’s heat in the outgoing stale air, it moves it to the incoming fresh air, but continues to push the contaminants and odors down the duct. Now you can benefit from ventilation that touts high energy efficiency. The heat recovery ventilator is ideal for colder climates. It’s also ideal for newer or remodeled, tightly-sealed homes that could contain pockets of stale and/or contaminated air. If you reside in a warm zone, you may want to look into getting an Energy Recovery Ventilator instead. If you live in the Midwest, you’ll most likely benefit from having both.
