Currently the outside temparature has not exceeded 16C for several days,
and
has dropped much lower at night. The house has remained mostly above 21C
with
a low point of 18C overnight.

The difference is due to solar gain, and general occupancy of the house,
good
insulation, and not due to any deliberate heating.

Yes.
and how does that effect what I said?
