Have to agree with MajorDanby. The physics is clear, heat loss is proportional to temperature differential, so for economy turn off when not required. No ifs, no buts.
Perceived comfort is a different matter and some people may not feel comfortable until the thermal mass has stabilised at the required temperature. Thus for comfort, they may prefer to maintain a higher base level of heating, even though it uses more energy overall.
Just to be pedantic (there’s always one) an object cannot emit cold, only absorb or emit heat. Although of course, it feels as if cold is being emitted even though in fact heat is being absorbed. Sorry, I will shut up now.
