Could you have under sized radiators and thus (on paper) would need

Could you see an estate agent going through a full set of heat loss

Bo but these days, I could almost envisage a regulation stating that
they have to do so to prove that the rads are correctly sized, and that
in the absence of such calcs, the heating would have to be described as
"partial" as a butt-covering exercise!
