Increase energy efficiency of your home by extracting heat from bathroom exhaust air and applying it to fresh outdoor air which is then distributed into bedrooms and living areas of your home. This also decreases the level of odors, chemical vapors and naturally occurring gases that become trapped in tightly sealed homes.
If your home is air-tight and energy-efficient, it may need more fresh air. An energy-recovery ventilator is one way get it without sacrificing efficiency. Sealing air leaks and adding insulation are two important ways of conserving energy in your house. But some homes may be so tightly sealed that they don’t allow in enough fresh air for a healthy environment. To allow adequate fresh air into your house you might need some type of ventilation system. Energy-recovery ventilators remove stale, polluted air from homes and replace it with fresh outdoor air.
In an energy-recovery ventilator, the heat exchanger transfers a certain amount of water vapor to the incoming air. A heat-recovery ventilator transfers only heat. Because an energy-recovery ventilator transfers some of the moisture contained in the exhaust air to the usually less humid incoming winter air, the humidity of homes with energy-recovery ventilators tends to stay more constant. This feature also keeps the heat exchanger core warmer, minimizing problems with freezing.
