Although it is cold - I actually don't feel cold enough to put the heating on yet (but then in my last house I had no central heating at all so I am hardy). Will normally stick a jumper on or a pair of socks first.
poohshunny - I had that problem with my radiators. You probably just need to rebalance them (you undo the screw on the other side). Only problem is, you will probably need to rebalance the whole lot. I did my own though, so no reason why you can't.
Though I've just moved house and it's the first time I've used it here, it would seem my thermostat reads low, I set it to about 17/18degrees, switched on the heating, went out for half hour and then come home to a sauna!!!
Mental note now made to set thermostat lower than I think it needs to be :)
