The weather here is totally crazy... for the second time this month I've had to turn my heating off completely for a whole day. Usually I leave it on at very low all the time in the winter, and only occasionally need to turn it up higher. A couple of days ago it was very cold and I turn the heating up, then when I came home last night at about 8, it was like an oven in here. I still haven't needed to turn it back on yet. The temp outside right now at 5pm, is 11C, which is about 50F, compared to a few days ago, when it was near zero at this time of day. Not that I'm complaining though, it'll mean I'm using less gas.
Look at all the fun I'd miss if I had thermostaically controlled central heating. ;-)
