Heat Recovery Ventilation (HRV)
In recent years, building and renovation techniques have changed considerably, in response to rising energy costs. On average, space heating account for about 65% of a home or commercial building’s energy use. Improvements to windows, doors, insulation, and other technologies mean that buildings are “tighter” than ever before. The average building constructed today is many times more resistant to air leakage than one built in 1985. If a building has been renovated, extra insulation and better windows have almost surely been added, in an effort to minimize the loss of heated or cooled air.
Tightening a building’s air envelope is good for energy costs, but can be bad for the occupants. Here in Winnipeg, the cold winters and hot summers mean that we tend to spend a lot of time indoors, and buildings that aren’t well ventilated can become too humid, and the interior air susceptible to growth of microbes and other pollutants.
The lungs of your home
The solution? Heat Recovery Ventilation (HRV). In most jurisdictions, the Building code will require a building have a complete exchange of interior air with fresh air from outside every two to three hours. A HRV will allow this ventilation to take place by passing the interior and exterior air through a heat exchanger, minimizing thermal loss by balancing the temperature between the two.
A good HRV system can increase thermal efficiency of air ventilation by more than 90%, resulting in an interior climate that is comfortable, healthy, and economical.
Reliable Heating and Air Conditioning has considerable experience with HRV units of all sizes, working in conjunction with all types of heating and cooling systems. We can help you calculate your needs, source an appropriate unit, and have our on-staff technicians install it and fine-tune it to your application’s specific needs. Your home or workplace will be healthier and more comfortable, and your monthly energy costs will go down.
