You Should Know
YSK - for all the things that can make your life easier!
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Opposite actually. Combustion of most organic molecules react oxygen with hydrocarbons to produce water vapor. Fire is humidifying.
Most released vapor is likely expelled out the chimney, plus due to increased humidity capacity of hot air it likely absorbs some from the home (especially with a fireplace, likely cooling down by absorbing water much faster than conducting its heat away) in some way before being expelled. A setup like this also likely causes a negative pressure, drawing air from outside which is also likely dry if it's winter cold.
Also, water vapor released through the chimney is lost energy (even if the steam isn't hot, moist air has more thermal capacity than dry air because water).
@bluGill
I find it unlikely that your dehumidifier would be catching fire in a fireplace. If that's where you're storing it, though, I'd ignore the recall.

Not if it is a ventless heater which is what o was responding to.
There is a comment about ventless, but you responded at the same level rather than to it. Your comment was ventlessless.
Arrgh, my mistake .
This explains why ventless heaters and fireplaces produce, in addition to toxic exhaust gasses, enormous amounts of water vapor. Enough to make it condense on your windows and walls.
1 pound of propane burned will produce 1.6 pounds of water.
In the short run the heat of combustion lowers the relative humidity (not absolute, but nobody every measures that). However most buildings lose heat faster than water vapor and so the continued combustion needed to keep warm eventually raises the humidity.
Now tell them why both AC and your heater are effective at dehumidifying the inside of your car so somebody can post a TIL.
The important thing is that how dry the air feels is based on how much water the air has in it as a percentage of how much it can hold (humidity as a %) and that colder air can hold less water.
Heating air is fairly straightforward. The air starts off cold and moderately humid (1 unit of water but the air can hold 2, meaning 50% humidity, a pleasant amount) and it is then heated up until it can hold much more but doesn't have any extra water added to it (1 unit of water in the air still but now it can hold 4, giving only 25% humidity, very dry feeling).
AC takes outside air (let's say 50% humidity with 2 units of water in the air and the air could hold 4) and cools it down, thus reducing the water capacity of it and forcing water to condense out of it (down to 1 unit of water in the air out of 1, with the other unit of water now being condensation dripping out of the system; the air is now at 100% humidity). This cold air then warms up inside your car as it fights with the warm air already in there, and this formerly cool air now has a greater capacity for water without increasing the amount of water in it, leading to a lower humidity (still 1 unit of water in the air, but now warmed up a bit so it can hold 3 units, giving only 33% humidity!).
I hope this makes sense and is helpful
Probably because it's conducted heat from your heater core and it's not fire directly heating your cabin. Water from the combustion is expelled through your exhaust. ¯_(ツ)_/¯
