Dehumidifier

Post by Clarkey » 10 Mar 2016, 18:36

Thought I'd share the below...

Although my garage is generally dry, I went the other day and my bike frame was damp... I guess when it’s humid outside the air gets into the garage then the moisture settles on the cold frame which isn’t good.

This probably happens more than I realise, as the next day it had dried out again leaving no real trace.

Making my garage 100% airtight would probably be quite difficult, lol, so I planned to get a dehumidifier to keep on top of it.

When I was researching, I noticed Amazon had a current offer, and they’re still available at that reduced price

Background info : there are two general types of dehumidifier, compressor or desiccant - in short desiccant are generally better for the UK – but full details here: http://www.ecoair.org/desiccant-or-compressor.html

The two currently on offer are the same make, and almost identical specification (maximum draw per day, physical size, storage capacity etc).  The Simple model has basic controls, the Classic model having fancy controls… to be honest although I was initially quite tempted with the Classic model, the more I read up the more I saw the Simple one seems to be better value as underneath they do pretty much the same thing:

Both of them have a 2 litre container, but also have an ‘auto-drain’ option, which is basically the ability to plug a hose into the back of it, which can gravity drain if you can put it somewhere suitable.

Also both seem to have a humidity sensor (i.e. they turn on when it goes above a particular threshold, and stop when they bring it down again)

For myself however - after reading the questions and answers on amazon I realised the Classic cannot be used on a plug timer as you need to physically press the ‘on button’ each time it gets power – the ability to use a timer plug is a key feature for me, so I bought the Simple model.

Simple - £102, instead of £150 - http://www.amazon.co.uk/dp/B00474K8SY" onclick="window.open(this.href);return false;

Classic - £127, instead of £169 - http://www.amazon.co.uk/dp/B008BZVCVM" onclick="window.open(this.href);return false;

I put the one I bought in my garage yesterday, and it drew about 1.5 litres in 5 hours on eco mode – they say keeping it on maximum all the time can shorten the life of the machine, so I’ll just put it on eco mode every day

Ventilation will get rid of condensation, you must have a cold water feed in there put some lagging round pipes if you do

The car park at work is well ventilated.
But my bike still got covered in condensation when i used to work nights?

Have to have a look for a water pipe i guess?

I just presumed it was damp night air and the fact the bike was cold?
As thats how condensation used to work.

If you leave the garage door open it will sort the problem.

Heating the whole garage would take a lot of power as the heat would leave fairly quickly, and much of the moisture would simply raise into the ceiling then fall again when you turned it off - a dehumidifier draws the moisture away

Of course more will enter so you need to use it fairly regularly, but that'd be worse with a heater

great idea clarkey ..are you going to use it permanently during the wet weather/ winter ? will running costs be much ?

Do you have a traditional garage ? brick walls proper roof etc or is it a concrete type with the asbestos type corrugated sheets on top .

My friend at the latter type and he also had the same damp issue as you , He got some of the expanding foam and sealed up at the eaves. Ran a draught excluder round the doors and laid a cemented fillet around the base on the inside. These seemed to do the trick and made it much more drier.
Maybe you can solve the damp in the summer by doing some work on it ?

Mositure will travel to the coldest place.
Put a sink drain pipe 12" long through the wall on the north side of the building at 45deg downhill from in to out. Run metal rod through it. Water will condense on the rod and run out the building through the drain pipe.
