Condensation , perfect storm.

[Count Steer]

More for my own reference than anything. Just plugged it in, started automatic setting (I’m guessing) and the starting point for humidity was 64%.

This is probably higher than normal as I’ve poached some eggs, got a load of washing in the machine and I’m currently descaling the coffee machine.

Primary reason for buying the dehumidifier is to speed up clothes drying which is already quite speedy as I used a Dry soon (iirc) heated airer. I’d like to think I’d get turbo drying speed with both running

Once it's switched off and restarted the next day, the RH starts at 80+! (Due to the condensation inside, which is why there's a cycle for storage, to dry it out).

I also use a couple of small RH meters so I can see roughly if the rooms are reasonably uniform ie no static damp areas.

I'm pretty much keeping the house <60 RH now.

I bought a couple of the 25L Meaco Which Best Buy's for the 'damp' side (road side) of the house, and they're working hard now the weather is turning - we're emptying the downstairs one daily.

Also got a 12.5L one for our bathroom to keep the damp/mould down, which is also doing well. I'm chuffed One for the garage is likely to appear soon...

My third dehumidifier arrived today, I now have Meaco, Ebac and a small silent night branded thing which does a bedroom well but not much more.
I've had the Ebac for a while, it's an 18l model and does extract a fair amount but it's got a much publicised AI smart control that makes little sense. I think it's designed to manage condensation which is odd as it was sold as a special version for DIY. The upshot of that is it keeps switching off when humidity is over 70%.
The Meaco also has an AI smart control but helpfully I can set a target and override the AI to dry clothes, much better.

The Meaco I've got in the garage/workshop has a drain "spout" so I've fitted it with a length of tube and run it outside to drain away - no worries about emptying it daily. (and it would need it - I can fill up a 5l bottle with de-ionised for the ultra-sonic overnight.)

For anyone who wants to get really nerdy I found this interesting, I knew all of the science in here but hadn't seen anyone put it together like this.
Upshot is the dehumidifier may use 200W of electricity but it will pump 800W of heat into the room. I have noticed rooms getting warmer than they should and this explains it but I found it still makes things more comfortable in summer, I don't have aircon like this American chap but I am certainly considering a split system now even if it's not going to cool the air.

Watched it all. Nicely explained.

I checked the dust filters on my ProBreezes today. The kitchen one wasn't bad but the bedroom one...really needed a clean. Lots of lint, but not too surprising for a bedroom.

The manual says clean every two weeks, which I thought was OTT but I'd say it's about right.

I assume all makes have some sort of filter. If you haven't checked yours for a while I suggest you do. (Particularly if you leave them running in a shed or garage with a drain fitted for long periods).

[Count Steer]

LOL. Prompted by Silly Car I just ordered another dehumidifier direct from Probreeze. 20% off! Woohoo!...

....which makes it exactly the same price as Amazon (with10% off!) but with £3.99 added for next day delivery.

Price fixing? Surely not.

Still, nice to cut Amazon out of the loop.

Edit: Oh no it didn't! Just had shipping confirmation and it's shipping with Amazon.

I can see how a dehumidifier in the house would need regular checking,but there's never anything I can see comes out of the filter in my garage Meaco. I give it a blow out the odd time for the sake of it.

Yes. I guess it depends what you're doing in the garage/shed really. As I mentioned, the kitchen one wasn't bad (tiled floor) but the bedroom one had a fair amount of lint on it after a couple of weeks.

Just thought it was worth a mention/remind, just in case. It can't help the efficiency if they do get a bit clogged up and some probably don't get checked from one year to the next.

Yes. I guess it depends what you're doing in the bedroom.....

Pillow fights,amirite?

A smidge of dampness in the air tonight


PXL_20251213_185926686.jpg

I had a burst pipe in the garage last year and the humidity wasn't that high.

[Nordboy]

My double garage seems pretty watertight (it's a garage so has doors etc, never really watertight) and there's no visible damp anywhere, but the last week I've noticed that there's the start of mould on some of my textile bike kit. There definitely seems to be moisture in the air. i've kept the door open today to try and get some fresh air in but may well have to either heat the garage or get a dehumidifier.

If I have to go down that route, any recommendations?

[Count Steer]

I've got 3 Pro-Breeze dehumidifiers and v pleased with them.

If you leave the door open and the humidity is high outside,then it'll just add to the damp.

My problems began when building regulation dictated my oil fired boiler must be housed outside instead of happily ensconced in the garage. My solution was to run a radiator in the garage and improve the insulation,so there's not such big temperature differences between cold snaps and mild weather which is perfect for condensation.
This works well most times to keep the humidity in check,but for those time when it gets out of hand,then the dehumidifier gets pressed into use.
I use the same Meaco as @Tricky which doesn't cost the earth to run. Loadsa stuff earlier in the thread.

I use a weather station thingy so I can read the temp and humidity in the garage from the house. This allows me to spot any rise and nip it in the bud.

[Skub]

@Nordboy I meant to add. I have a little blower sitting on top of the radiator. The fan activates when the radiator heats up. This gently moves the air about,which also seems to help in my case.

Dessicant dehimidifiers are better for very cold spaces but they cost a lot more to buy and run and I haven't seen any domestic ones for sale. Mould doesn't grow well at very low temps so a standard compressor version shoud help.
Avoid Peliter (solid state) dehumidifiers, much less efficient and usually sold as small cheap units but I've seen a bigger version in Lidl this week. If you pick a box up and it doesn't weight as much as a fridge then it's probably the wrong one.
I've tried different brands and found Meaco is good but maybe a bit pricey for a garage, I have a couple of own brand 12l ones form Morissons and Tesco that work well and cost about £100. You'll need to plan what to do to empty them as the tanks can fill quickly, most can attach a small hose that runs out of the door so it doesn't need emptying.

[Count Steer]

As a rule of thumb it helps if you can maintain >7°C in a space. I have a couple of greenhouse fan heaters with thermostats for the unheated conservatory but that can get a bit spendy on electricity. The panel heater in the cabin is set to 7°C too.

[Rockburner]

Another vote here for Meaco. I'm sure I've posted the details somewhere in this thread.
