    Heat rate (efficiency) - Wikipedia

    A 100% efficiency implies equal input and output: for 1 kWh of output, the input is 1 kWh. This thermal energy input of Therefore, the heat rate of a 100% efficient plant is simply 1, or 1 kWh/kWh, or 3.6 MJ/kWh, or 3,412 Btu/kWh To express the efficiency of a generator or power plant as a

    However, if a furnace is rated at 100,000 BTUs and is 92% efficient, then the heat output will be 92,000 BTUs (100,000 x .92). It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output. Use a Smart Thermostat. Smart thermostats can also improve the efficiency of your heating and cooling system.
