HRV
Heat Recovery Ventilators
As our homes become more energy efficient, they become more hazardous to our health.
The problem? Allergens and harmful indoor fumes from paint, plastics, carpets, adhesives, and household products stay trapped inside today’s tightly sealed, well-insulated houses.
Although you’re saving money by conserving energy, you’re paying a much greater price with your health. Polluted indoor air can cause respiratory irritation and worsen allergy symptoms for everyone inside.
It’s a risky tradeoff, and one that can be avoided.
The Heat Recovergy Ventilator (HRV) makes your home a healthier environment by replacing polluted, stale air with fresh clean air from outside. This system heats your home with maximum efficiency, and provides the additional benefit of heat recovery and a delivery system for air conditioning. You breathe better air indoors and enjoy the financial benefits of an energy efficient home.
How Does It Work
At the core of an HRV is the heat transfer module. Both the exhaust and outdoor air streams pass through the module, and the heat from the exhaust air is used to pre-heat the outdoor air stream. Only the heat is transferred; the two air streams remain physically separate. Typically, an HRV is able to recover 70 to 80 percent of the heat from the exhaust air and transfer it to the incoming air. This dramatically reduces the energy needed to heat outdoor air to a comfortable temperature.
Benefits of a Heat Recovery Ventilator
- Brings a continuous supply of fresh, filtered outside air into the home
- Exhausts environmental contaminants for improved indoor air quality
- Saves energy by recovering heat from exhaust air in the winter
- Cools incoming air in the summer
- Controls excess humidity
