Not for me, George. I'm neither a stoic nor a Spartan, so I have had the central heating running for about 16 hours a day for the past two days. Prior to that (it turned bitterly cold here a couple of days ago), I would turn it on manually in two-hour bursts as needed. When the cat comes in at 13:00 instead of 02:30, I know that it is cold outside !
