I am thinking of getting a steel container for storing machines and chems
if I insulate it and put in a heater do you I would get a problem with condensation
cheers Jim
Used to have one that I stored my motorbike in.
I'd think a good layer of insulation should be enough to prevent the frost getting a hold, although if as bad as a couple of years ago it might not be quite as certain.
You could use a convector heater on intermittent timer, although if it's the same as the one I had you'll have to drill a hole to feed the power cable through.
