So I've decided the best thing given my situation is to get a new boiler, the oil situation has to be removed. I've met with 4 contractors and 3/4 recommended 95% AFU Lochinvar Knight boilers. The quotes range from $6695 - $7650. FYI I have to use propane because natural gas does not come out to my house. I'm curious about people's opinions of Lochinvar here because I've noticed there aren't many! One contractor recommended 105,000 BTU the others 150,000. The house is roughly 4,000sq ft including the basement and at present there is "attic space", but more like the other side of the second floor; it will be renovated as such. Thus I need to account for that extra heating in my boiler purchase now. The current water heater is upstairs venting out a completely different chimney than the boiler. None of the contractors recommended an indirect water heater. Would that save me money...hmm although it would cost more to buy a new one? I have to make this decision quickly...first snow was yesterday! I had one other contractor who didn't do any sort of evaluation really, the others mostly measured the floor board space and checked out where the new piping was going to need to go, or where it could go. The one who didn't recommended a 100,000 BTU Dunkirk. They had the cheapest quote. Oh and the Lochinvar's are self-modulating. Any opinions or experience with Lochinvars?
