Mini (non electric) dehumidifiers... anyone tried?

I've been umming and ahrring about getting an electric dehumidifier, and I've read the posts on MSE about condensation, mildew/mould etc. They seem to be the way to go, and I've read they cost just pennies to run, but my OH remains unconvinced. He thinks only the small low wattage ones would be cheap to run.
The thing is, we only have storage heaters which are expensive to run and are only placed centrally, not in the bedrooms. We can't afford to put them on until we start getting really cold snaps, then we keep all doors open to try and circulate the warm air around. The double glazing is old and starting to break down, and the house only has a plastic panel under the windows rather than brickwork, with no windowsills. We get mildew/mould on the little-used north-facing bedroom walls.
My point is, the mini non-electric jobbies seem popular according to this thread, but are they man enough do you think to sort those rooms out? Maybe double up in each bedroom? :rolleyes:
