|Howie - insulation/ventilation is the best answer, but it's a biggish job and

Ah. I like the greenhouse-heater idea. We have one of those beds
with a base made of 2 sections, wooden frame covered in fabric. I
could stick a heater in there and it will heat the bed (a bit),
whilst radiating warm air away from it all around (including next
to the problematic outside wall. Would this work I wonder?

All good points. Thanks. I have a dehumidifier - but I don't want
to run it in the bedroom. I might be able to find a place for it
on the landing though. I WAS going to sell the damn thing!
