boiler efficiency by 4% to 6%. Using an air heater to raise the com-bustion air temperature is commonplace with utility boilers but is almost never done with packaged boilers. The nec-essary ductwork is expensive and can affect the low-NO. x. performance of the Boiler owners often cannot operate a boiler if the emissions are out of compliance.
The efficiency rating of your boiler should be taken as an ideal level, and plants should work to make their boiler's operational efficiency as close to this rating as possible. The operational efficiency of a boiler is an expression of the percentage of heat energy generated from the heat energy input.
FEMP has calculated that the required ENERGY STAR-qualified residential gas boiler saves money if priced no more than $1,389 (in 2017 dollars) above the less efficient model. The best available model saves up to $2,265.

INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER
Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.
