I was talking to someone today who has a large apartment building and is heating it with two new efm 520's. The cost to heat it with oil was $26K per year, so I'm guessing it uses a lot of coal.
During the conversation, she mentioned that it had an ash removal system, created by the Amish, using grain equipment and it works very well.
I've had alot of people ask about such a system, but never knew that one existed; not at a reasonable cost, anyway.
Our efm dealer, Perry Webb, has any information necessary, in case anybody is interested in this system. I don't know the cost.
