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.
apply to low-income energy efficiency programs.2 As described below, energy efficiency administration encompasses all the functions related to the planning, oversight and management of energy efficiency programs, including decisions on what programs to fund with ratepayer dollars.

air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a …
The Department of Energy (DOE) establishes energy-efficiency standards for certain appliances and equipment, and currently covers more than 60 different products. Authority to undertake this effort was granted by Congress, and DOE follows a four-phase process when reviewing existing and developing
efficiency of a boiler orfurnace (< 0.3 million Btuh), which is the heattransferred to the conditioned space divided by the fuel energy supplied. Combustion Efficiency (Ec) ANSI Z21.13 1991 Measures the ability of aboiler to burn fuel Ec = 100 — flue loss (or the %ofheat input rate) Thermal Efficiency (Er) HYDRONICS INSTITUTE 4 June 1989
E c ≥ 88.5. Large Oil-Fired Steam. >2,500,000 Btu/h and ≤10,000,000 Btu/h. Oil. Steam. E t ≥ 85.5. *Both thermal efficiency (E t) and combustion efficiency (E c) are based on 10 CFR Part 431.86 - Uniform test method for the measurement of energy efficiency of commercial packaged boilers.
