Hello fellow reefers i have a serious question

[Delphinus]

I would think no, but maybe your furnaces just simply provide enough volume turnover to prevent humidity buildup. Being that they are high efficiency, theoretically they cost less to operate than mid efficiency, and therefore you might get more air turnover per dollar spent on heating than, say, I do. In my case the HRV gives me air turnover without having a huge impact on my heating costs. There is a bump of course but much smaller than it would be without an HRV.
