In general, what temperature do you keep your house living areas at during
the winter?

70 F. During the day when nobody is home I'll set it back to 68.

If it's windy outside, I might set it for 71 F overnight.

My two outside thermometers read 11 and 14 right now. During the past
couple of weeks it has got to -4 F.

Down to -12C again tonight - Was up to 0C (32f) today - as high as 11C
the last few days - and highs in the -20C range for the last few
weeks. With winds hovering around 60kph today it felt a lot colder
than the thermometer indicated, with a bit of lake effect snow blowing
around.

Duringthe day we keep it around 18C, then after dinner when sitting
around watching the news or TV programs we often bump it up to 22 -
then down to 17 or so overnight

If I'm home and it's sunny and not too windy and outdoor temp is 25 - 40
I'll set the indoor temp to 69.

Two story, 1975, brick exterior on first story, second story could use
more insulation on walls. Original Pella windows. Forced air natural
gas (original furnace, standing pilot, natural draft combustion exhaust,
single stage). Drum humidifier. Main floor humidity reading of
somewhere between 30 - 40%. Furnace fan runs 24/7.

About the same as mine, but I replaced the original aluminum frame
windows with LowE2 glass in Rehau vinyl framed windows about 20-25
years ago. Much tighter and better insulated. Replaced the furnace
with a 2 stage mid efficiency furnace about 20 years ago. The DC fan
saved a lot on the hydro bill.

In the summer my AC will struggle to get to 73F and 50% humidity when
its 85F and 65% humidity outside. There have been times when it's like
75-80 F and 75% humidity outside in the summer. When it's like that
outside, 73F feels cool, even cold (initially). Condensation has formed
on windows *on the outside* a few times. It would feel uncomfortable
(too warm) right now if it was 73F inside.
My AC can keep the house uncomfortably cool in 30C weather, even
with 85% humidity but we generally don't keep it very cool.
Electricity is too expensive at peak time
