Determining & Testing Boiler Efficiency for Commercial

2016-4-12 · efficiency. Boiler efficiency, in the simplest terms, represents the difference between 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 will result in substantial fuel savings.

Understanding Wood Boiler Efficiency and EPA Ratings

Oil and gas boiler efficiency is somewhat comparable to EPA accepted wood fueled boiler efficiency ratings, but the comparison is far from perfect. Due to the more consistent nature of the wood pellet fuel and the near complete elimination of human operation, tested wood pellet boiler efficiency will more closely match actual field use than

Maximizing Small-Boiler Efficiency | HPAC Engineering

Figure 1 depicts a typical efficiency curve for a condensing boiler relative to return-water temperature. Two main points can be gleaned from Figure 1. First, operating a boiler with a return-water temperature above 140 F yields a peak thermal efficiency of roughly 88 percent. That means it basically is performing like a non- condensing boiler.
