Hello I'm hoping someone can help me decide on two things; the first is which natural gas boiler to have installed. Based on all measurements and calculations (and all contractor recomendations), my home requires a boiler about 100,000 BTUs. I'm considering the Peerless MI-04 (105,000) and the Crown Aruba 3 series. Both are similar, but the Crown has stainless steel burners (lifetime warranty), while the Peerless has "aluminized" burners (no warranty). Both are very similarly priced, so that is not a factor. Any thoughts as to which is better (easier to maintain, easier to service, more reliable, etc.)? Both are very similar with respect to efficiency. Second, for either model, should I get a standing pilot or electric ignition? I realize the pilot is slightly less efficient, but I hear the electric ignition may not be as reliable. Thoughts? Oh yes, my existing boiler (Repco) is too old, too large (150,000), and in need of repair. I don't want to sink any more $ into it. Lastly, I'm getting an indirect fired water heater (probably the PP-40), which I do not have now. Thanks in advance for your help.

i am trying to find a boiler/water heater that will do 2 thing in one unit where boiler water does not mix with domestic hot water i know baxi luna has that but feed back was not that great and one more thing would it damage a tankless water heater if i use it as a boiler ( pipes and radiators are black iron) i know how to hook it up i just thought that it might be a cheaper option
