Not many people know about the advantages of a Heat Recovery Ventilator (HRV) but they are extremely beneficial in our climate. Over the last few decades, building standards have advanced to a point where we can construct homes that are extremely airtight—increasing efficiency and helping lower monthly energy bills. However, an unintended consequence of these upgrades was the loss of fresh air ventilation in homes. As all the small gaps and open spaces were closed up, the ability to filter in fresh air throughout the home diminished.
Adequate home ventilation is extremely important because we need to replace the stale air in our homes with fresh air from outside. Without proper ventilation, moisture can accumulate in your home and create health hazards with mould and mildew. Odours from cooking or general living can contribute to stagnant indoor air and appliances like gas ranges can leak poisonous gasses into your home.
Often, people will open some windows to let fresh air in, which works when the weather is nice but can be counterproductive in the winter—exchanging the stale air for fresh air comes at the expense of letting all the heat escape.
Think of an HRV as having an open window in your home to bring in fresh air without the drawback of letting warm air escape. When the unit is installed, heated air passes through the unit on its way outside, while fresh air comes in through an intake valve. The heat from the departing air is transferred to the fresh air—preheating it so it doesn’t enter at the outside temperatures. Most HRV units are able to capture up to 80% of the heat from the exhausted air.
As we head into the autumn season, think about adding a Heat Recovery Ventilator to your HVAC system to increase home comfort during the winter months.
