Establishing an Energy Efficiency Recommendation for

Energy National Test Standard, 10 CFR 430 March 1984 Measures (at steady state) the annual heating 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 …

Improve Your Boiler's Combustion Efficiency - Energy

Typical boiler efficiencies are 80 percent for natural gas-fired boilers, 75 percent for biomass-fired boilers, and 83 percent for coal-fired boilers. The calculation of effective electric efficiency is the CHP net electric output divided by the additional fuel the CHP system consumes over and above what would have been used by a boiler to produce the thermal output of the CHP system.
