De humidifier | Mumsnet

Posting for traffic. I detest sleeping in a warm room in summer. Does anyone use a de humidifier to help make the room more bearable for sleeping ? It's a small room 13ft by 13ft

No but I do have one elsewhere.

I’m not sure how it would make the room significantly cooler tbh, it creates its own heat with the motor. It also isn’t loud but if you’re not used to white noise that’ll bother you.

It won’t make the room cooler, I use one in the winter for damp and it actually releases a bit of heat

I have a small bedroom too that's getting warm at night. It's not a cheap solution (but it's one that will last years and totally worth it) but I would unequivocally suggest a Dyson Tower Fan - Tower as opposed to regular round shape as it covers a wider area.

How would this work? I have a dehumidifier and it makes any room/area quite warm when in for any substantial period of time. If it’s in a bedroom, it needs to be turned off and room aired for a few hours before that person goes to bed to avoid the room being an oven.

A dehumidifier will make the room warmer. You want a fan.

Why would you buy a dehumidifier for £70 plus and not a fan?

I have a mobile a/c unit that is the size of a fridge! It can be quite noisy but was a godsend last summer when it was still 26c at night.

We have a quiet tower fan but it just circulates the warm air

Dehumidifiers don’t cool the room. Ours gets warm and has the opposite effect.

Off topic, but aircon for 26degC . Why? What are you setting it to? Ours doesn’t go on unless it’s over 32C (some of us in our house happily hang out until 35 but others pike early). When on it’s set to 25. Even then though we don’t have it on overnight. Ours is zoned and has bedrooms as one zone but I always thought that was so they could be excluded and you just have living areas done if people are not spending time in bedrooms during day so as not to waste cooling rooms not being used?

But how do you think a dehumidifier will cool the air?

caulkheaded · 17/04/2022 14:55

You need ac or another fan - that isn’t the way dehumidifiers work (unless you’re about to say you live in a jungle and that’s why it’s not.

Insurance company put one in our kitchen following a really bad leak which wrecked the floor. The noise was like having the extractor fan on full blast, horrendous! Had it for a week, so glad it's gone!

That’s not typical for most dehumidifiers. Ours is very quiet.

We have a dehumidifier, it makes room warmer as it sucks the moisture out of the air. It isn't a coolant.

Quiet as it is I can't imagine sleeping in a room with it on.

Alwayswonderedwhy · 17/04/2022 15:04

Our dehumidifier makes the room warmer. Just use a fan.

Is assume it was heavier duty than a normal domestic dehumidifier. A shop locally had one in its basement, looked nothing like my Ebac dehumidifier and was a lot louder.

Love my dehumidifier but it warms rooms rather than cools them, which is handy in the winter, and I turn it off in the summer as there's no point leaving it on when all the windows are open.

Dehumidifiers turn water vapour into liquid water. SInce water vapour has more energy than liquid water they also give out heat and more heat from the motor and inefficiencies. To cool the room you would need to do the opposite - evaporate water. So hanging a wet towel in front of a fan will cool the room (and make the air damper). Like most things it’s thermodynamics.

I like the bedroom to be cold, 16c is my perfect temperature for sleeping. I have the window open in winter but last summer nighttime temps didn’t drop much lower than 26 some nights and it was just too warm for me to sleep.
