High Efficiency Steam Boiler? — Heating Help: The Wa

Stack Temperature It really boils down to stack temperature. (Pun intended.) It's conservation of energy. Whatever heat goes up the stack doesn't go into the heated space, A high efficiency furnace or boiler sends it's combustion products out at less than 200 F, but even an "efficient" steam boiler might have a stack temperature of 300 F or more.

The first floor is a separate apartment and has its own steam boiler. My question concerns the boiler sizing. From reading the posts I know it is very important to size a steam boiler based on the connected load. The connected load is 180 square feet steam. There is a boiler rated at 158 square feet steam and the next size is 271 square feet steam.
