Not that I 'like it colder' - but, as I said, I think that most of us probably expect/accept/tolerate short-term downward excursions in temperature during Summer which are colder than the temperature we would expect to maintain during Winter.That doesn't seem to happen very often but if it does then it is cold. ... Conversely - you are saying that you like it colder in the Summer than Winter.
That's probably a red herring. My house is quite large, but the bits of it that I usually (can afford to!) heat routinely to reasonable temperatures are very probably no larger than yours. The rest usually gets minimal heating!My place isn't as large as yours.
Kind Regards, John
