The heat flow rate can be calculated as h = (4.2 kJ/kg oC) (1000 kg/m3) (10 liter) (1/1000 m3/liter) ((100oC) - (10oC)) / ((30 min) (60 s/min)) = 2.1 kJ/s (kW) The 24V DC electric current required for the heating can be calculated as

• ### Boiler Efficiency Calculation: a complete guide

Aug 29, 2017 · The calculation of boiler’s fuel efficiency boiler should consider the consumption amount of fuel used, so it is very appropriate to be used as a point of boiler economic analysis. Direct Method There are two popular methods for calculating the fuel efficiency of the boiler; the direct method and the indirect one.

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.
