Purchasing Energy-Efficient Large Commercial Boilers

FEMP has calculated that a 3,000,000 Btu/h gas-fired hot water commercial boiler meeting the required combustion efficiency level of 95.0% E c saves money if priced no more than $79,100 above the base model. The best available model saves the average user more: $94,300 in lifetime energy costs.

Furnaces and Boilers | Department of Energy

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.

Improve Your Boiler's Combustion Efficiency

the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas less combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a steam value of $4.50/MMBtu, the annual cost savings are: Cost Savings = Fuel Consumption x (1 - E1/E2) x steam cost
