Condensation , perfect storm.

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

I’ve got one of them as well, dries my laundry out nice and quickly, I’ve no tried it in the pantry, only room which appears to suffer from damp, what with being subterranean, but very pleased and the resulting water keeps the iron topped up

@Nordboy I meant to ad. 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.

I’ve just invested in some Smart Air Boost radiator fans, they have exceeded expectations in terms of distribution of heat from radiators and increasing overall room temperature, more than happy to endorse them although I’ve noticed they have started to go back to non-sale prices. I paid £60 for an XL (Currys) and £85 for three standard ones (High Street TV, should have been £100 but the Honey extension on Safari managed to load a £15 discount).

Already got 2 solutions that do work;

I've got a Meaco, but when running it costs close to a fiver a day so it quickly got boxed up and put in the shed, if I could seal up the garage and not need to go in and out during the week I've no doubt this would settle down once all the humidity has been pulled out of the air but we use the space.
Similarly I've got a 300w tubular heater in there, but that got switched off when the electricity prices went through the roof some years back

Our spare room is used to dry clothes and has a pulley hanging from the ceiling for when bedding is done. It was always a cold room and window was dripping with condensation in the morning. Wife bought a dehumidifier in the sales and its been brilliant. Its on all night and does not run away with the electricity/ Window condensation has gone and the room feels warmer.

This is the little bugger

Called a 'Sheila Maid' apparently. I miss the one we had at the last house in the utility room/darkroom. (Previous owner kitted it out with double sink, lab taps etc as a darkroom + washing machine, drying rack etc).

Weather here is really damp at the moment, last 3 days have been reasonable temps but everything is wet due to the humidity. Don't think it helps living next door to a huge wood, round here always seems more damp/wet than other more open areas. Anyway was farting about with the bike the weekend and was worried about the condensation but doesn't seem bad in the garage at the moment. Then I remembered the first 15 years of my riding my bikes all lived outdoors under covers and ridden in all weathers, so decided to not worry as whatever happens won't be as bad as that I'll start to worry if the GSXS ever makes it to Mr Orange/Mr Blue classic territory!

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?

I got myself a thermpro and chucked it in the garage. 87% humidity, that's pretty damn wet in my book?

So, I'm going to have to go down the humidifier route I think. That's a £100 I could have done without spending but if I don't I can see everything being covered in mould.

It costs to solve the problem regardless of which way you skin the cat.

You can run the dehumidifier a lot,or permanently.

You can employ some form of heat,then the humidifier is needed less frequently.

Either way will do,but they both cost something.

I think I prefer the second method,especially if I'm out there doing any work.

As a dehumidifier removes water it releases energy, so a 100W dehumidifier could provide the equivalent of 200W* of heat.
* I don't remember any accurate figures.

+ Ventilation. At 87% it's probably damper than outside!

(I used to use a greenhouse fan heater in the otherwise unheated conservatory because of condensation, but now I just leave some of the upper, small windows open and just don't use it in winter. Seems to do the trick).

Cant be arsed scrolling back but would a diesel heater not be of use. Is this not pumping dry heat into the garage. The Chinese ones can run on various fuels so probably red diesel is best choice. They are on a thermostat also and costs next to sod all to run.

Iirc diesel generates a lot of extra moisture?

Yep, water is a natural byproduct of burning any hydrocarbon fuels, that and CO2, assuming complete combustion otherwise you end up with carbon monoxide… So it is the same with paraffin, oil, propane, butane etc. Key in damp environments is adequate airflow to expel the waste gas & vapour before the latter condenses on a cool surface.

All of those years spent with a science teacher must have ingrained some knowledge

S'why you have the exhaust outside of the building you're tyring to heat, which is a double win as it solves the dying from carbon monoxide poisoning problem at the same time.

Why would anyone be so stupid to have that inside?

For the same reason idiots still put disposable bbqs in their tents at night... Darwinism in action

I bought a 30l pro breeze which I put on in the garage last night. It's been running all night and the moisture has dropped by nearly 10%, which is a reasonable start I guess? Still a fair way to go though as it's still 82% humidity in there

It'll go up and down, you'll never "fix" the humidity at one level.

It'll probably do something like 10% on day 1 and the % drop a bit as the humidity drops for each day after that - weather dependent though.

That's a whole lot of moisture in your garage. If you check the humidity level outside you might find opening the door for a while (with the de-humidifier off, obvs) and ventilating/airing it helps reduce the level a bit before running the d-h again. Assuming it's not slashing down outside.

based on what's happening so far I'd say 10% is about right. Outside is currently 90% here at the moment so it's always up against it a bit. I'm not worried about it being really low, just lower than it is at the moment. Already I can feel the difference in there.
