Current indoor humidity?

[ExtraSlow]

How many times have I complained about my humidifier?
Anyway? With the cold snap we are about to get, what's your current indoor relative humidity?

We can do a discussion too, but mostly I just want to see what people are able to maintain.

Mine is 30%, and humidifier is set to run 100% of the time the furnace is in a heating cycle. My heating cycles are quite short though, which means there isn't that long for the humidifier to work.
Also never use bathroom exhaust fans during showers or anything. Never run the furnace ventilator fan. Kitchen hood fan very rarely.

Happy weekend!

Sitting at 26% at my thermostat with the humidifier set to a minimum setting on my nest ( you don’t actually choose a % with Nest).

My windows have a tendency to freeze up though which drives that set point.

I use my hood fan and bathroom fans religiously.

[bjstare]

Ours is around 25%, and if I'm not mistaken our house humidifier is off entirely (although, we have a little humidifier in my daughters room so it gets closer to 30%)

[Darell_n]

Mine is at 32% and dropping. I you have a good humidistat it will have a remote sensor to mount outside and adjust the indoor setting according to outdoor temperatures. I don't imagine my humidifier will energize for the next week or so, looking at the forecast. Also noteworthy is having my furnace fan on constant allows me to run the humidity quite a bit higher without destroying the wood casing on my cheap windows. Cochrane is forecast for a low of -44 on Tuesday night, so I will need to get the RH down in the 20's if I don't want massive ice buildup on my windows and inside the bedroom closets, that are cantilevered in my house.


This is from my radon detector in the basement, so humidity is higher there than the main floor.

Nests humidifier setting is comical lol. But it works haha.

Normally 36%, but cranked it up to 46% the past week as the entire family has been sick and wanted to make it a bit more comfortable.

That said I do have frost control turned on the ecobee, so once outdoor temp gets to -11, it reduces it to a max of 28% to avoid frosting windows. One of my favourite features of the ecobee actually.

23%. I dont have mine set on at all. The water line was shared with the fridge icecube maker, and when its line burst, i just shut off that supply line altogether. I should probably hook it all back up one of these days.

Do you actually have to cock your head 90 degrees to look at your ecobee?

[sabad66]

Yup, it’s a trade off for having a feature rich thermostat

But seriously not sure why it did that. Pic looks right side up on my phone, not sure how to fix that if I uploaded as an attachment

This thread is almost as great an idea as the "Any Psychro's Out There?" thread that I was about to start! But, since you beat me to it... I guess this one will have to do.
I was looking for a refresher on how to read a Psychrometric Chart to compare the absolute humidity from the outside air at -19° & 70%RH with the inside 20° & 40%RH. I'm trying to most effectively get my humidity down by using my HRV. I vaguely recall it's something about drawing lines along the wavy lines etc, but that's about it... It's the most relevant thread derail of 2020!

More on your topic... I have a "Certified Green" tight house and as a result, I can't get it below 35% pretty much no matter what I do. The unreliable dial on the wall says about 30% but my weather station says it's currently 41%. The water to my humidifier is literally shut off and we always use bathroom fans although rarely use stove hood fan (because, like all stove fans, it's 123dB).
I find some condensation on the windows if its above 40% but I try to get the levels down for a couple days before a real cold snap so I don't get ice and I'm using my HRV to do that.

Humidity in my kitchen has increased with a few showers and doing some dishes.

Same. Ours is always around 36-40%, never kicks the humidifier on and we run bath fans for 30 minutes after we shower.

My humidifier hasn't worked in 3 weeks, currently 23% goes up to around 30% during meal prep and dishes

[The_Rural_Juror]

32% with circulation on all the time. I have to direct air towards the windows to stop the frosting.

[The Cosworth]

My ecobee says 18% right now based on the -22 reading. I never thought about circulating more and putting it higher. I'll have to give it a shot.

Psychrometric Chart

Now there's a term I haven't heard in a while and could have went the rest of my life without hearing it again.... haha

[sabad66]

Well I caved and turned off frost control and set to 40%. With the entire family still sick, the 18% humidity in the house has been killing us. I’m sure the windows will frost up this week but whatevs

ah, good to know. I've got an ecobee that defaults to 36% and my windows are a disaster.

if you have really old windows, i would set that Window Efficiency factor to 1 which will limit your humidity down to like 20% or something.
