I am looking for a boiler and wondering if anybody has any recommendations. Boilers are not common at all in these parts so I am pretty much limited to internet research and purchase Purpose: -Run radiant floor hydronic system -Snow melt for concrete stairs and sidewalk in the future (300-400 sq/ft) -Already have a direct vent gas water heater that will handle DHW duties -Will handle roughly 1/3 of heating load of house, fireplace does the rest. Will kick on at night and off/on during day depending on outside temp. -Have water-to-air coil and blower to heat detached garage. Very high intermittant heat load, when I am in there I turn it on, when I leave I turn it off. 4-car Desires: -natural gas -simple, cheap, reliable. Don't want anything too fancy -all of the electronic controls and increased price of a mod-con turns me off to the idea -outside air intake (think they call it sealed combustion??) -prefer power/direct vent to outside wall -would consider a standing pilot, but a electric ignition is preferred -staged output would be nice but not opposed to having two smaller boilers instead (Murphy hates me, spares are good...) Coldest design day heat loss of the house is 200k BTU (very large old house). Average with the fireplace going is around 40k BTU. Garage is around 60k BTU on the coldest design day but would likely average in the 30k range. With cheap natural gas prices and the low heat load with the fireplace going the operating savings of a 95% over an 80% efficient boiler will never pay back the increased cost of the initial purchase.
