What is heat recovery ventilation?

Proper ventilation is a critical part of a healthy environment for your building and home inhabitants. Toxins can get trapped inside without enough fresh air to replace the air circulating throughout the home and can make you uncomfortable or even sick. You can open a window to let in fresh air but it is not a practical thing to do during the hottest or coldest months of the year and it will let in pollen and other allergens. A heat recovery ventilator, or HRV, will help keep your air fresh without letting in too much hot or cold air and unwanted particles.

The HRV is best-suited for both colder climates and dry or desert areas because the HRV takes heat from inside your home or building and transfer it to incoming fresh air. Energy recovery ventilators (ERV) are more suitable for humid climates with mild winters. The HRV process enhances the comfort of the inhabitants and also controls moisture and condensation that occurs in winter that can cause damage to windows, insulation and furniture.

Another excellent benefit of HRV is that it allows the user to control how much fresh air is entering the home so you can adjust it based on current environmental conditions. If your home or business is located next to a restaurant or some type of factory you would not want undesirable odors coming into your space. If the system is designed well the fresh air intakes can be located away from the sources of the odors and pollutants. The exhaust locations can also be located away from sensitive areas if it is too moist and may cause damage or have family and customers breathing in unpleasant odors and pollutants.
