Ah, so temperature is, as I thought, the problem. If it's a
sunny day the conservatory could get the length of 25º, but
at night it'll go down to maybe 12º depending on the
external temperature. But we don't tend to keep the house
that warm as a whole either: 17º is about the maximum I'd be
comfortable with in my bedroom at night.
