I have a Heat Recovery Ventilator, do I still need a Plusaire?
Definitely yes. A Heat Recovery Ventilator (HRV) works by bringing in as much air as it blows out, it is what is called a balanced system. Without this balance the HRV would not work. Unfortunately houses also exhaust air with fans, clothes dryers, central vacuums etc., so the house is exhausting more air than it takes in. For every cubic foot of air that leaves a structure, a cubic foot of air is required to replace it. Since the HRV is a balanced system it will not add the extra air that is needed. A Plusaire is designed to bring in warmed air at a rate equal to or greater than the rate at which the house is using it. Q: I have a new house that is tight, what benefit would a Plusaire give me? A: A tight house costs less to heat than one that has more leaks but the air within the house is more likely to be stale and condensation is likely to be more of a problem. Excessive condensation can lead to mould and mildew building up in corners and areas that do not have a regular air flow. P
