So with winter coming up I thought I'll see what options there are. Last few days has been cold. I have ducted heating (gas) and apart from it taking forever to warm the house in the morning, its also super expensive.
Things I thought of doing:
close the vents on the cooling as they aren't being used. The heating vents are different.
Closing doors to rooms that isn't used in the morning and make sure they seal well
Install a few panel heaters in the house and always keep them on when its cold (possibly timers with Home Assistant)
Are those even worth doing or are there some better things to do
people who say "put on a jumper" are either very tough, or live in top notch well insulated and well orientated homes, or just simply don't know what cold temperature actually is.
