Hello Everyone, I've been lurking and learning for sometime and figured I would join in. I'm starting construction on a highly insulated ICF home soon (basement to ceiling in ICF) and I'm thinking of going with an Eko boiler with 1000 gallons of storage. I live in rural Alberta and have all the wood a guy could ever want at my door step. This area also has several coal mines within an hour of town and I was thinking coal might help reduce my wood chores. I know almost nothing about coal but did read one thread referencing brown coal for these boilers. Apparently brown coal is one of the lowest BTU coals and the local coal here is thermal coal which I would guess is a high BTU coal. Anyone have experience burning coal in wood/coal burning boiler? I would like to supplement with coal but it sounds like our local coal may be a little too skookum for an Eko boiler. Thanks for any input!
