Hi i am new to this forum. I just bought the Logwood indoor boiler (YBOC36) made by Marathon heater company (from NY) does anybody else have one?? Are you happy with the unit? I bought this boiler for the reason that it can burn coal and wood. There are plenty of coal mines around this part of PA so getting coal is not a problem. What can I expect from this unit? Am I going to be happy or wish I bought somthing else???
