In my home country it seems underfloor heating is very popular, hence my question. The apartment has two gas heaters which should be more than enough, though I must say that having gas burning in the room where I sleep does not something I am eager for. There are combo AC units but I haven't had yet the chance to put them to test.
From my observation the real issue is poor insulation. I still have to make up my mind about whether it is because cold weather is a novelty here or because constructors just go with the cheapest option.
Mitch, you sound very harsh. Keep it down a notch and go chase some other Scientology forum if that's what entertain you. We value your advice and your experience but you don't need to make yourself unpleasant.
