Thanks for everyone's responses to my last post.
I am getting an estimate on replacing my New Yorker boiler. I'm interested in using a system other than oil. My New Yorker that is power vented (no chimney) is noisy and smells of exhaust. It may be because the power vent comes on right when the furnace fires up and not before as I think it is supposed to.
Anyway, the estimate will be for a Buderus high efficiency condensing boiler. My question is will this be cost effective in the long run if I only have forced hot water baseboard (finned copper)? I've heard that the higher temps reduces condensing, therefore lowers efficiency? How much would this lower my efficiency and would it still be a good decision?
