Our house gets pretty bad condensation in the winter. Most of the upstairs bedrooms get a fair amount of water on them and the window ledge in our bedroom sometimes has a small pool of water on it, not helped I'd have thought by as the radiator is below the window so warm one side of curtains/cold the other.
To help we open a window when showering which generates a shit load of steam, furkin horrible in this weather and drives me nuts thinking how much we pay to heat the room only to let the cold air in We also mop/hoover (special hoover for the job) the water up on all the windows. I did buy a dehumidifer and it does pull a fair bit of water out of the air but without leaving it on pretty much all day we are fighting a losing battle and I'm not sure how much this will cost to run long term. We leave the bedroom windows open a tiny crack to help with ventilation.
Yesterday Mrs was moving furniture about in the living room and discovered 3 spots of mold. 2 small ones by back patio doors, 1 bigger one behind an armchair to the right underside of the front window in the corner.
The house is a 70's house and there are no airvents in the walls at all, so I'm guessing ventilation could be a big source/problem. Should I get some put in or open windows more? Will this help as I'm guessing there is a fair amount of mosture in the air outside at the moment.
Heating we have our heating set on about 21C but thermostat is in the living room so this room is always warmer than rest of house. Should I have it up higher to try and heat the windows/walls more? Does heating make much of a difference?
Drying clothes - we do this a fair amount as we have a 9 month old so our washing loads having increased about 10 fold this winter, not much we can do there really.
What are my best options for preventing this?
Ta in advance
