Why do you need it to be cooler than 18c?

They're trying to heat it.

You’re replying to somebody from the UK. They want it warmer than 18C inside. In winter it is typically much colder than this outside so they’re saying their heating won’t get the house warmer than this even if windows are only cracked open.

I think they want more than 18c. 18c is pretty cold to sit in for a prolonged time.

At 18C I wouldn't even put on a sweater. People need to stop being so wimpy. 10C is a good target temperature during the winter.
