Fellars, Getting ready to can the oil-fired boiler for good. It's only 10 years old but I refuse to buy more oil. Which would be the more reliable stand alone system to use with hot water baseboard and a domestic coil? A pellet boiler or wood gasification boiler? I have a pellet fireplace insert I can use as a backup. Keeps the downstairs toasty and the upstairs at least 60 on cold days but no heat to basement. I am considering the Harmon Hydroflex 60 which I can get for around $5,000 but if a wood gasification system is more reliable I would consider that as well. Watcha say?
