We need to replace our 17 year old oil boiler that recently developed a crack. our heat loss calc is roughly 90,000. Heating with hyro air - 1 air handler in basement next to boiler, the other in the attic, quite a distance away from boiler. Current hot water in tankless coil, but we will replace with an indirect (40-50gallons). Two story house approx 2400sf in New England with typical NE winters. My question - would a low volume boiler like the Utica trifire be a good option given our system? i like the installer, but not sure about low volume and the Utica trifire. I do not know if we would be better off with a buderus given the two air handlers and the fact that one is far away from the boiler. i also have friends who swear by buderus with their same hyrdo air type set up. Would really like to see some fuel savings. Thanks in advance for any comments.
