I am currently finishing my basement in my 100+ year old 2-story home. As part of the project, I will be changing the gravity-fed radiant heating system into a in-floor radiant system for the first floor and basement, with a "homerun" set-up for the radiators on the second floor.
I just sold my Weil-McCalin 140,000 BTU boiler, and want to replace it with an energy efficient model. My home heat-loss calculations show a heat loss of 40,000 BTU/Hr. Yes, the previous boiler was overkill, and so were the monthly bills (the boiler temp was never more than 105 degrees- it was set to 170- the house was just already hot before the boiler got anywhere near that).
Anyway, I am looking for a 50K BTU efficient boiler. I have found two models that fit my needs-
Peerless Purefire PF-50 http://www.e-comfortusa.com/products...as-boiler/2084
Peerless PI-N50-N http://www.alpinehomeair.com/viewpro...ctID=453061902
I'm sure there are other brands out there. Anyway, these two units are similarly priced, but other than the fact one has a 3" vent and the other a 2" vent, I really can't tell what the difference is.
Any help is apppreciated.
