Air exchange systems are a necessary addition to your home, as they aid in purifying your indoor air without losing energy. With ventilators, you have two options to consider: a heat recovery ventilator (HRV) and an energy recovery ventilator (ERV). Neither of them is right for every situation, which is why it’s important to be able to differentiate between the two so that you can choose the perfect complement to your indoor air conditioner and heating unit.
What Is an HRV?
An HRV is a device that pulls in fresh air from the outside while expelling stale air from the inside. It also captures heat during the process to prevent energy loss. HRVs are perfect in cold areas and in homes with excessive humidity during the heating season. This ventilator also eliminates much of the moisture in the indoor air, rendering interior spaces more comfortable.
What Is an ERV?
This device works the same way as an HRV, except it transfers some of the moisture from the air going out to the air coming in, which helps keep the humidity in your home at a consistent level.
In other words, an ERV recovers both heat and moisture. This feature is useful if your house normally has dry air during the heating season.
During the hottest months, its ability to limit the amount of humidity coming into your home helps increase your comfort indoors. Running it along with your AC can translate to improved air quality and decreased cooling load.
Which One Is Better?
As mentioned before, neither an HRV nor an ERV is right for everyone. Each home is different, and so are the people living in it. If you want to reduce your home’s indoor humidity, then go with an HRV. If you’d like to recoup the moisture in the air as you purify it, then opt for an ERV.
