It's been lovely and sunny today, with a chilly northerly breeze. This meant the front of the house was nice and warm (and we sat on the balcony it the afternoon), and the back was chilly and windy, meaning we got 3 loads of washing dry!
We've got the heating off as we don't want it coming on yet, as the house is mostly quite warm, though drops lower if we keep the windows open for a bit too long. It soon heats up when we close the windows though, hence not needing heating.
It's only our second autumn in this house. I think the heating went on in October last year. Once the house doesn't reheat itself to a comfortable level on its own once windows are closed we'll turn it on to be controlled by the thermostat.
We do tend to have the bedroom window open all year. We have a 2.5 tog duvet for most of the year (swapping for a bedspread in summer).
As for @cardibachpersistently saying 'medicate it' like a stuck record, it's not always easy to get the right mix of hormones with HRT to sort all issues. Sometimes you'll just be left with symptoms, no matter what. HRT doesn't necessarily solve everything.
As for central heating smelling? That shouldn't be a thing. I'd suggest a service / heating system replacement!
