I feel like my house needs a bloody good airing, but it's soooo cold and my heatings on!

I always have bedroom windows open, but can shut all the doors. My downstairs is very open plan, so quite tricky.

Oh yes, ten minute blast so that moisture does not build up

No but then I live in a draughty victorian terraced house and I figure in the winter it airs itself!

definitely, gets rid of condensation/ smells! Only a few mins tho'

Yes - every week.....

Yep. Every morning - 30 minutes with all upstairs windows open and duvets on window sills (if it isn't raining).

Yes, several times a day. DH thinks it is necessary to leave front or back door wide to the wall everytime he goes out to check the car, put the car seat in, put the bins out, put something in the shed, fetch/chop logs, split sticks, etc. etc. His 'I am going out and may be some time' forays are often extended by a blether with the next door neighbours. 44 years I have been trying to break this habit!!!

no - would love to, but have storage heaters, so would lose heat and not be able to replace it.

Yes, I hate it when it feels all stagnant and stale in the air. Luckily we got over enthusiastic with the boiler and radiators that it is like a sauna again after 20 mins

Yes. I leave bedroom windows open all day and do a quick 10 mins downstairs too. It drives DH mad, money flying out the window...etc (yawn)
