The amount of ash doesn't bother me, but the extra coal burned does. Last year I went through 4.5 ton. That heated a 2,000 square foot house at 73 and heated all our DHW, that's with 2 teenage daughters.
I must admit I forgot to say one thing. There is one slight difference from last year, maybe not so slight. I am going to blame not telling you this because of the hour at which I submitted my question. The gasket on the lid to the hopper was hanging on by a thread, so I removed it and planned on reinstalling later when I figured out what ot glue it back on with. So right now it has no gasket. would this create the problem. I thought I had read that so long as the lid was in place it would not bother. Maybe I'm wrong, I've bben told that several times (been married 25+ years).
Also, does Kasey Casa produce their own coal or do they jsut break it and sell, buying from whomever they can get bulk , raw coal from?
