System efficiency measure of the percentage of potential energy contained in a fuel source that actually gets delivered as heat within a home heating system i e an 85 efficient system wastes 15 of its heating potential.
Thermal oil heater efficiency calculation.
Even adjusting for efficiency heating oil still produces more heat per gallon than propane.
Cop the change in the heat level of an area the energy consumed.

Boiler efficiency is in general indicated by either thermal efficiency or fuel to fluid efficiency depending the context.
2019 11 28 general formula for oil consumption per hour of oil fired boiler.
Air is assumed to be dry at atmospheric pressure and at zero elevation.
Use a smart thermostat.
Calculation assumes true counter flow.
Fluid temperature ranges from 40 f to 200 f.
3600 thermal power fuel calorific value boiler thermal efficiency.
Smart thermostats can also improve the efficiency of your heating and cooling system.
The comparison thus far has focused purely on the amount of heat equivalent amounts each fuel produces.
In thermodynamics the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy such as an internal combustion engine a steam turbine or a steam engine a boiler furnace or a refrigerator for example.
Cop thermal output btu hr power input kw 3413 btu kwh or.
Fluid properties are used at the average temperatures.
Acfm is assumed to be at the average air temperature.
It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output.
Cop is expressed as.

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.
For a heat engine thermal efficiency is the fraction of the energy added by heat primary energy that is converted to net work output secondary energy.
