Good to know it will fit! 800lbs wow... I guess that some are more.
I get my coal from the the chimney sweep energy corp. http://www.chimneysweepenergycorp.com
5.50 baged or something like 5.25 baged for 2400lb's. #40lb bags. I contacted Cornwall coal last year they are cheaper and deliver baged and bulk.
What can I expect to pay for a VF3k with water coil and aquastat controls? Around $4K ?
