Condensation on windows this morning
There was condensation on the outside of my windows this morning - something I've noticed a fair bit after replacing the windows late last year.
2 hours 30 of heating so far this month, with the thermostat set to either 16 or 16.5 while I'm in and 14 when I'm out.
It's presently 17 down and 20 up, the heating's been off since 7 AM (it came on for 30 minutes as it fell to 15.5).
