Most homeowners consider having an air-tight home to be like a badge of honour, as they should, but it comes with its challenges. Having a properly sealed home is great for efficiency, but it limits the amount of fresh air that circulates throughout your home. A Heat Recovery Ventilator, better known as an HRV system, allows you to reap all the efficiency benefits of having an air-tight home while still providing you with an endless cycle of fresh air.
How does it work?
An HRV system exchanges the stale air in your home for fresh outdoor air. The system captures the heat from the outgoing indoor air and uses it to preheat the incoming fresh, cool air. Heat Recovery Ventilators are designed to work in conjunction with your forced-air heating system and the pre-existing ductwork in your home to disperse a constant flow of fresh warm air.
What are the benefits?
The biggest benefit that HRV systems have to offer is that they drastically improve the air quality in your home. During the winter, we have to spend a lot of our time indoors, and if your home is properly sealed, that means you aren’t exposed to very much fresh air. HRV systems allow you to get all of the benefits of fresh air without sacrificing heat like you would if you were to open your windows. This constant flow of fresh air will reduce a lot of the negative impacts caused by dry indoor air that Canadians suffer from during the winter.
When should I turn on my HRV?
This is one of the most common questions we get from homeowners about HRVs, and it’s a valid concern. Some people believe that HRV systems should only be used in the winter, and others think that they should be used all year long. Technically neither answer is wrong, but we suggest using your HRV system anytime all of your windows and doors are closed. The system can cool the incoming air during the summer in the same way that it heats the air during the winter, so you won’t be sacrificing efficiency during the summer months either. Regardless of when you are using your HRV system, just remember to shut it off if you are going to open the doors or windows so that you don’t waste energy. It’s best to run the systems on “minimum” or “vent,” but we find many homeowners prefer the 20/40 setting because it only runs the system for 20 minutes of every hour.
