21oC in winter, off in summer. I ain’t going to waste energy when you can just close the window if you are cold.
I don’t have aircon either, not that I would be able to afford it even if I did have it.
Oh and the thermostat lies anyway and is actually just on or off so. 30 minutes in the morning and 1 hour in the evening. Well except last winter where I decided food was more important than warmth and just turned it on when necissary to keep the place habitable.
