Condensation On Your Windows? An HRV Can Help!

January 7, 2019

It seems that at least in some ways, we’ve gotten too efficient at building the homes we live in and finding condensation on the inside of your windows is a good example of this. Water vapour condenses on the colder glass of an inside window. This relative humidity can cause some moisture-related problems, although there is an innovative way to treat this problem – a Heat Recovery Ventilator (HRV). These HRVs are a great way to lower the indoor relative humidity and decrease that unwanted condensation that shows itself on the inside of your windows. If you live in a climate where heating the inside of the home is a seasonal and frequent occurrence, this will eliminate unwanted condensation. These units are especially helpful since they also keep the air quality in your home high without adding large numbers to your energy bill. There are two air streams and both the exhaust and outdoor air pass through a heat transfer module. Not only can these HRVs eliminate unwanted condensation, they can also recover 70 to 80 percent of the heat that would otherwise be lost in exhaust air and transfer it back into the house. Finding the right unit is part of the key to getting the most from one of these HRVs. It’s a great idea to look for one that has an automatic humidity sensor that can kick the ventilation rate up a notch or two when someone is taking a shower or doing something else that would create a high humidity level in the home.
