Yes there will always be cool air moving across the floor to the stove. I haven't noticed much of any difference after hooking up an oak.

Do you mean at all? As in the OAK isn’t worth the trouble, or particularly about the floor air?

On really cold days I notice the bedroom walls sweat a lot. I have new windows, but the house in 1950, so I’m guessing no wall insulation. It’s 1950 brick or stone, and plaster. I’m really hoping that the OAC is a noticeable improvement.
The moisture on the walls from the humidity compensating on the cold walls. Lower humidity in the house would help. Proper wall insulation would help. Proper bathroom and cooking fan usage will help. An OAK is not a cure for this, but you still should install one for other reasons.

Shoot. I was hoping...

I did solve the issue the few times it happened with the dehumidifier, but it just seems odd to run a dehumidifier in one end of the house and a humidifier in the stove room.

I was thinking it was the outside wall pulling “snow air” through trying to feed the stove. It only happens slightly when near 0 and for sure when it gets negative, and only on the far outside wall.

For me I don't think it changed much of anything. But for some people it is needed. I can't say if it would help you or not.

Don't run the humidifier. If you have moisture on the walls and windows you don't need it.
 
In the stove room it isnt so much apparent. In far rooms is where it is more noticeable. It isnt do or die, but it does make a difference.

Yes absolutely some houses it will make a huge difference. Others it sont change much

You have a high humidity problem and you are running a humidifier? I think you answered your own problem. The humidity you are seeing on the surface of the walls is minor compared to the damage the humidity is causing inside your walls. No humidity is migrating in, there is no humidity to come in if it is zero outside. It is all frozen. The humidity is from in the house going out.

The oak will prevent/reduce air from being pulled through leaky walls or around windows . Thereby not increasing humidity in far rooms . Only use a kettle or pan on stove when humidity drops below 30%

I have a below grade set-up. half basement. we also have a fresh air duct for the water heater and the furnace. I tend to leave the door to the utility room open a crack for the stove, thinking the fresh air helps combat sucking from the rest of the 1900 sq ft split level

Yes and no. In the stove room it gets somewhat dry, but probably not 30% ever. I’d say there it gets 40-50%. I was worried about my acacia/teak hardwood floor in that room, so if it dipped to 40% I would turn on a little humidifier but no kettle. The area I live in does remain pretty wet. Now that I’ve heard 30% it’s got me thinking otherwise :)

Acacia is a very stable wood I wouldn't worry about it. I also wouldn't worry about it being to dry until it drops to 30% or so.

That’s good to know. Here I was worried about below 40 or even 50%. I’m not even sure it can get below 30% here :)

Thanks!

50 is about as high as you want to go.

I just checked and I’m around 60%. Of course no stove on, because it’s 70 degrees today, but the outside is 35% humidity. Dehumidifiers are now on...

And that is why you have moisture issues

When u go to put your oak in go to your local tool rental and get the proper size hole saw for concrete. You will thank yourself

I don't get how the humidity inside is 60% inside when its 35% outside. Something else is going on there. Maybe I'm missing something?
 
Good thing we found another dehumidifier just yesterday on Facebook Marketplace!

Look up the dehumidifier recalls. Millions were recalled for fire hazard. I only found out when mine started to catch fire. Luckily I was home and smelled it before it was too late.

He's running a humidifier.

Not to beat this topic to death ,but definitely confirm the 60% ( that’s really dangerous for kids or anyone with compromised health issues) that’s mushroom farm levels . 40-43% is what I try to keep my basement where my stove is ( i use a kettle ) occasionally I’ll sleep downthere anything around 50% and I’m wheezing and coughing

Its the ambient temperature. Inside air is close to 70deg which will hold more moisture and then give a higher percentage reading. Lower outside air cannot hold as much water - hence lower percentages. Relative humidity is a bit of a wonky term, that's why dew points are a better source for water vapor in the outside air.

That’s what I was just reading, but thanks for that. Water condensation on the far walls at below zero temps is making sense too, as I read the science. That’s why they recommend lower humidity at colder temps.

I try to keep my hygrometer around 50%. Around here it’s just too hard to get much lower. And yesterday it was 35% outside but quickly climbed to 60+%. Right now we are sitting at 88% outside.
