      BOILER EFFICIENCY GUIDE - Cleaver-Brooks

      key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

      Is a high efficiency, condensing gas boiler the best

      Aug 13, 2018 · For example, a 30-year old boiler might be 70% efficient, meaning that for every dollar you spend on gas, 30 cents of heat escapes through the chimney or vent pipe. In comparison, a condensing boiler may provide up to 96% efficiency, which means that only 4 cents of heat escapes. That’s a big difference!

      Oct 01, 2018 · This results in increased boiler efficiency. Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy will be carried away by the flue gas. On the other hand, the boiler system takes in cold water, heats it to steam, and uses
