Heat recovery ventilation works independently of your normal heating system. These flow past each other without mixing physically but the heat is drawn from the stale air to the cold air, which is then fed back down into the pipes and into the rooms. The stale air, minus its heat, is then expelled into the atmosphere.
What is an HRV in HVAC?
What is an HRV? A Heat Recovery Ventilator is a system that exchanges the stale indoor air with fresh, outside air. During the heating season, an HRV also captures the heat from the exhausted air and transfers it to the incoming air, preheating it before it enters the home.
Should HRV run in winter?
In winter, set the dehumidistat just low enough to prevent condensation on windows. Do not shut off or unplug your HRV. This can result in high humidity levels, which can lead to mould and mildew growth and unhealthy living conditions.
What should my HRV be set at in winter?
If you are using an HRV, then a good rule of thumb would be to set the winter time humidity level to 30% and then monitor your moisture levels.

Does an HRV clean the air?
An HRV is a controlled ventilation system that helps reduce high humidity, pollutants and odours by replacing stale air with fresh warm air. All Genuine HRVs have two fans and an in-built “Air to Air” Heat Exchanger, which transfers available heat from the exhaust air stream to the cold fresh air supply.
Does HRV Have filters?
HRV systems also contain filters that keep particulates, such as pollen or dust, from entering your home. Airtight homes equipped with HRV systems will also have substantially lower energy costs per year than having ventilation without heat recovery.
Is HRV or ERV better?
The best option between an HRV and an ERV depends on your climate and specific needs. If your house is too humid in winter (above 60% RH) then an HRV is the better choice, as it would surely get rid of excess humidity while an ERV would tend to keep it at a high level.

What does a heat recovery ventilator do?
A heat recovery ventilator system (HRV) is ideal for homes located in colder climates, where there is excess moisture during heating season, since the unit allows to get rid of it. A HRV system supplies continuous fresh air from outside in the house.
A heat recovery system can work via a ventilation system which is positioned at the top of the building. Rather than just draw the stale air out and replace it with new stuff, it first of all works to draw the heat from the outgoing air and passes it to the air which is coming in.
Do you need a heat or energy recovery ventilator?
Strictly speaking, no , you don’t need heat recovery to live comfortably. Every home, however, needs ventilation of some kind, and just letting inside and outside air mix has several disadvantages.
How does a heat recovery ventilation system work?
In a heat recovery ventilation system, as the exhaust air travels back to the furnace, it passes through a copper heat exchange coil. The coil collects heat from the air and transfers it through the unit to the fresh air supply. This recovered heating energy is then used to warm the fresh air before it is distributed through the home.
