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.

Are modulating burners really worthwhile? - Heating Help

The most common turndown ratings in commercial boilers range from 3-1 up to 10-1. Turndown is how far the burner firing rate can be lowered and still effectively fire. For instance, a 3-1 turndown burner means that the burner will be able to drop to 33% of its firing rate.
