HELP me choose a natural gas chimney vented boiler
I have baseboard heating and need to replace my 1983 Weil McClain boiler. It is currently an input of 140K BTUs and output of 110K BTUs. One plumber came to give me an estimate. He only measured the baseboards and supposedly just factored in a 10% heat loss with no assessment of the house. He recommended a Peerless mi-04 unit with 105K BTUs. I want a unit that is built to last that has a good history of minimal problems (does that exist?). And how do I know I am picking the right size without doing a heat loss assessment. Is there a way to just guess? I live in an old 1910 home that has been renovated in the 80s.
Can I get opinions on Peerless owners or plumbers?
I welcome any thoughts on Crown, Burnham and other other brands that use gas and are chimney vented. I am not interested in direct vent or too high efficiency since I do not believe my chimney is lined. Please provide model numbers if possible. I am having a hard time picking within the same brand line. What makes one better than another other than efficiency? Thanks in advance!!
