Dehumidifier icing up?

[Feelingonesway]

I have a Seago YL-2007. Bought new this year. All working well - well was - but on one of my visits to the boat today I found it all iced up (Chichester). Now I know its buddy cold at the moment but anyone else have this problem? I am sure there will be answers about putting a heater bar in the boat but... seems a bit overkill?

Maybe its just me being bemused but I didn't expect it to ice up so badly. I know it was only 3-4 degrees C today but I am guessing its been frozen up for a week or so since I last went to see the boat.

My first experience of these things was this winter, so I'm still coming to grips with it. There have been a couple of times when I have gone down to the boat, found the de-hum running when I got there but not a drop of wetness in the drain tank. It probably has coincided with the coldest spells. Recently I have taken to running an oil-filled radiator on a very low setting, alongside the de-hum. That seems to have worked.

I seem to remember a thread or a google search saying, their quoted efficiency is at normal house temperatures and as the temperature falls they get less and less efficient. This may be why some have a hot gas bypass feature. I was advised to get one with this feature for my boat.

Make sure you have a heater on in the area as well, that will help it work. Not sure if it will stop it freezing, but it will not be working at very low temperatures.

all compressor dehumidifiers become increasingly less efficient below 15 degrees C. The air in the dehumidifier also is colder than ambient air, so greater risk of icing.I think from a quick look at specs of yours, if under 15 degrees, it turns off the compressor for 10 in ever 40 minutes, leaving the fan running, to try and reduce frosting. This is obviously not going to work in freezing temperatures.


For use in cold temperatures, you really need a hot gas compression dehumidifier (still will suffer decreased effectiveness at under 15 degrees) or an absorption or desiccant dehumidifier, which doesn't have a compressor, and will remove water vapour even at low temperatures.
For use on a boat, an autostart, which means it will restart automatically after a power cut is also a very useful function

My cheap and cheerful solutiuon to this problem is to use a mains timer switch...on for an hour, off for an hour, and repeat. Gives the ice time to melt. Seems to work.
