new boiler choice in New Hampshire
 
Built an insulated "mudroom" -- ready to relocate & replace my 18 yr old Trianco Heatmaker with a non-condensing propane boiler. I have a small house, good windows, moderately well-insulated and baseboards. I did a heat load calc for 78 Delta T and came up with 56,000 BTU not including domestic hot water. Only 2 adults in the house, no dishwasher.

If possible, I would like it to make domestic hot water, as well as central heating.

I have been quoted on Buderus, Triangle Tube, Biasi Riva. It's so hard to sort it all out. All quotes are in the $9000-$10 grand range.

With the Buderus GA124 & Biasi Riva I will need a separate electric water heater. The Triangle Tube Solo 110 Prestige Excellence is a combi unit, but it's condensing, and I will never get the extra efficiency I'm paying for.

Any one have suggestions / experience with these? Alternative suggestions?

thanks in advance, RW

I'd recommend the Weil McLain Ultra 80, with an indirect water heater. Its a condensing boiler. But you would be surprise at how much of the higher efficiency you do get. There are many myths that condensing boilers don't do well on high temp baseboard. they are however, just myths.

Thanks for your answer.

What do you think about aluminum heat exchangers?

The aluminum blocks/cores/heat exchangers work fine. Have quite a few in, and no problems from them being aluminum.
