New oil fired baseboard system

KBP&H_3

After 6 years of dealing w/ propane $ and a 87% eff hot water boiler,, it's time to tear it out and change to oil that will end up costing me HALF as much as propane to run... Starting fom scratch-- 78,000 BTU load of four hanging zone valves and 1- 1" return, one 50 gallon direct fired water heater    nothing else in the boiler room ,,, who  has the best way to go with this,, so input please.. from THE WALL'S top guys... as follows, boiler   ?    ,buffer tank   ?  , control setup   ?   ,thermostats or RTU's,,,, let's see  THE WALL's best options......

I'm assuming

the BTU figure is from a heat-loss calc, right?



If that's the case, I'd go with the 3-section Solaia. This is a 3-pass, low-mass cast-iron  Biasi-based unit that has a Net output of 79,000 BTUH. You can get it with Beckett (AFG or NX) Carlin or Riello burners. It heats up quickly and, like all 3-pass boilers, is easy to service.



Here are some pics of one such boiler we installed with a Triangle Tube 40-gallon indirect.



Definitely go with outdoor reset. Not sure if you'd need a buffer tank.
