The humidity in my house is over 70%, and we have condensation on windows all day and moldy. I have been trying my best to get it down but it wont go, and I am confused why its not. I just wondered how best to do it when its now winter, and we are keeping heating off to save money, so house is cold.
- I have a positive input ventilation system blowing air in from the attic space, which should be pushing humid air out
- We put clothes outside to dry (we have a canopy for shelter) and not much on radiators - kids towels after showers in evenings. Finish clothes off in tumble dryer but thats vented outside.
- Have a bathroom extractor fan
- Have an extractor fan above oven
- We keep some windows like my bedroom and bathroom windows open slightly to get air in
- Outside humidity is 52% at 13C.
- Attic space is 64% at slightly higher temperature than outside
- upstairs in house varies between 69% to 74% at 17C to 18C.
So inside the house is much higher than outside, even though we have windows open.
Thing is, house is freezing due to posi vent and then of course windows open, and no heating on. Its 16C at the moment. Windows soaking from condensation still even next to open window.
I cant believe there is so much water in the house. The shower in the evening would produce a lot, but we have an extractor fan and bathroom window open.
Should we close the bathroom door AFTER showers to stop humidity entering rest of the house? The shower is the only major source of water vapour I can think of.
I would like to close our windows to keep heat in, but then humidity goes up, mid-70s.
Is all the humidity because we keep heating off most of the time? We treat ourselves in the evenings and put heating on for a few hours. Should we keep the heating on a lot more, keep the house warmer, windows closed, to evaporate off condensation? but then it all goes into the air so humidity would still be high and that will be expensive these days.
So I am looking for the best practice to keep humidity low, whether its a cold or warmer house? I dont know what else I could do.
Thanks
