So do I. I've ben told to burn kiln dried logs, not coal at all, but all my heating is run off the fire, the logs are barely warming the radiators, and I have to throw another one on every half an hour. I'm almost out, and there's no way to keep the fire going overnight when it's coldest. Only managed to keep it burning for 6 hours yesterday, which did very little to warm anything.

Avoid 10 however you can, it's dire. I can't find anything.
