AHS' Automatic Coal-fired Stoker Boiler
I'm considering buying an Alternate Heating Systems (AHS) Automatic Coal-fired Stoker Boiler for my low pressure steam system - who installs these in the Boston area? Do I need to get the ASME boiler because it costs $2000 more than the non-code one? If oil prices remain much higher than the other fuels, I foresee a great mass exodus from oil to coal - the opposite of what happened 40 years ago. Of course, the coal burners now are 85% efficient and burn as clean as gas.
I've calculated that I would save $800 this heating season if I converted from oil to coal. The conversion would pay for itself in several years. I've talked with my burner service and he didn't want to talk about it for some reason. Your input would be gladly appreciated.
