Healthy Home Showdown: ERV vs. HRV

Healthy Home Showdown: ERV vs. HRV


The Healthy Home trend is gaining serious traction as building envelopes become tighter, leaving builders wondering which devices are best suited to market a healthier home.

More builders are constructing tight homes in response to energy efficiency concerns, but a tight home can lead to stale air. And that can have adverse health effects. Mechanical ventilation systems allow fresh air to cycle into airtight homes.

Proper ventilation is key when marketing a Healthy Home, because it can improve indoor air quality (IAQ) while turning stale air into fresh air.

The problem is deciding which type of ventilation system works best for your projects. But you can breathe easy, because TecHome Builder is breaking it down for you.

Energy Recovery Ventilation (ERV) works well in colder climates with no excess humidity and warmer climates that have high outdoor humidity.

ERVs have a year-round application. In conditioned homes, when it is more humid outside, an ERV limits humidity coming in. During winter, the system limits the amount of moisture expelled.

An efficient ERV can reduce the load on the home’s air conditioning system by removing humidity in the air before it is sent into the AC or dehumidifier system.
