HRV – Heat Recovery Ventilator | ERV – Energy Ventilation Ventilator

Todays homes are being built to more and more exacting standards especially in cold climates like Alaska. What that means is they are what we call “tight” homes or homes in which there is very little air leakage in or out of the home.

While that is great for efficiency reasons it can be very dangerous for the occupants health unless proper equipment is installed. HRV (heat recovery ventilation) or ERV (energy recovery ventilation) systems deliver fresh air to a home’s interior.

What do HRV’s and ERV’s do and how they work?


The fans on HRV (heat recovery ventilator) and ERV (energy recovery ventilator) units pull fresh air into a house while exhausting stale air out of the house at the same time. In most cases, the fresh air is delivered into the living areas such as the family room and bedrooms, while warm moist polluted air is taken out of areas such as kitchen, laundry, and bathrooms.

While doing this, the heating recovery ventilator or HRV, and energy recovery ventilator or ERV, pass the fresh air coming in and the stale air flowing out through the unit housing. Inside the HRV or ERV unit the heat from the warmer air exiting from inside the house warms the cooler air being drawn in from outside as it passes by each other. The air however is not mixed in any way inside the HRV which would contaminate the clean air.

An HRV (heat recovery ventilator) and an ERV (energy recovery ventilator) do basically the same thing, except an ERV is designed to allow some of the moisture of the inside air to remain by allowing a minimal mixture of air snide the unit.

Why use an HRV or ERV?

52_grande~v~Venmar_AVS_-_Novofit_1_5_HRV_-_available_in_Quebec_onlyThere are many critical reason to use a quality air exchange and heat recovery system in your home. Air quality is number one. Statistics consistently show that many airborne sicknesses and illnesses are transmitted through polluted air. They also show that the indoor air quality of most homes is very poor and is well below health quality standards. Dirty moist polluted air that cannot escape your home poses one of the greatest health threats to your family.

Mold is another hidden danger in many homes. Once again, contaminated moist air is the main cause of mold growing in homes. Homes that are too “tight” without proper ventilation systems are breeding grounds for mold spores and make the perfect incubator for all kinds of sicknesses.

Many allergies are caused or at least amplified by living in and breathing in environments with polluted and dirty air. Pet dander, smoking, wood smoke, and other irritants are greatly amplified when recirculated inside a home where people are living, breathing, showering, and cooking with little or no fresh air circulation. this is especially true in climates like Alaska where home are closed up tight for long periods of time.

For these reasons as well as many others a quality HRV or ERV system in a must for homes in Alaska. These systems have proven to increase health and air quality for the occupants living there. We have several HRV and ERV choices and we can help with designing a system for you.
