We had a neighbour once who liked to tell us how their thermostat never went on until the first of November.
I would shamefully nudge ours on the second week of October.
We don’t keep a warm house (18 is as high as it gets) but I love the smell that comes through the vents that first time you turn the furnace on. Old burnt heat smell.
It feels fantastically warm as the hot air rushes through the house. Then two days later I grimace at how cold it has grown.
