It's pretty chilly in Melbourne, Australia tonight and I've just remembered our central heating is on the blink. Makes a funny noise just as the fan starts pushing through air and then switches off and restarts the cycle 30 seconds later. It's only blowing out cold air so I guess the gas isn't igniting.
My office is sufficiently warmed by 6 computers but for the rest of the house I've turned on the oven in the kitchen.

It's 4:30am so the current trend of the temp is DOWN
