My heating is set at 21°C (70F) for daytimes and 16°C (61F) for the night time, so it doesn’t come on at all during summer, and a lot of spring (UK). During winter when it gets colder out (like below about 6°C/43F) I will usually need to whack it up by a couple of degrees, or give it a little extra blast in the morning to warm up. Its an old building (late 1800s) and my flat has external walls on three sides, and a cold empty basement below, so it can get quite cold when the outside temperature drops.
Edited to make it clear i mean my heating thermostat, because I realised most people here are talking about AC and that’s very rare in homes here.
