Use a stove with a balanced flue.Hi all
A bit of background: I live in the Brecon Beacons surrounded by a lot of trees and a stream, all of which I presume lends to the high relative humidity (RH) in my house. It often sits in the 70% region and sometimes even creeps above 80%. In times of high RH, opening the window is counter productive and causes it to rise. We use a dehumidifier when it's at its worse.
We have a wood burner in one room, which does not have a direct (external) air feed. It's not been in long, but it does do a good job of reducing the RH. We'll soon be installing a further two wood stoves. I totally see the sense in direct air in as much as it will minimise drafts, and negate the need for a vent which would let copious amounts of cold air into the house...
But when it comes to humidity I can't get my head around it. No direct air to the stove means more air changes and air circulation in the house (I think?), which could be looked upon as a good thing. But then again, it also means more air coming from outside, where the humidity is higher, so perhaps it isn't such a good thing. And maybe that's all too basic a way too look at it anyhow.
I wondered if anyone out there has a better understanding of the science behind this and could explain which option is best and why, when it comes to humidity?
Air drawn in may be moisture rich but that direct into stove and then expelled.
