Started looking at wood and pellet boilers recently for my new house and heard good things about the EKO boilers. I see they are on sale at newhorizoncorp website for a good price. Do you know if it's ok to install this to heat a house since they don't seem to be EPA certified. How much cleaner burning and more efficient are the new EPA certified wood boilers? Would I have a problem with code compliance in NH installing an EKO boiler in a shed away from the house? From what I've seen, there is a big price difference between this boiler and other similar size boilers costing around $10000. I plan on installing water storage to make the system more efficient since the house is small and well insulated.
