Boiler heat loss is the loss of money if your.
Thermal oil heater efficiency calculation.
2019 11 28 general formula for oil consumption per hour of oil fired boiler.
140 000 x 90 percent 126 000 btu gallon for heating oil.
Even adjusting for efficiency heating oil still produces more heat per gallon than propane.
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.
Acfm is assumed to be at the average air temperature.
This is the measure of the energy efficiency of a system s ability to change the thermal conditions of an area based on the ratio of energy input relative to energy output.
It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output.
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.
Fluid temperature ranges from 40 f to 200 f.
Smart thermostats can also improve the efficiency of your heating and cooling system.
Fluid properties are used at the average temperatures.
Liquids are considered incompressible.
Calculation assumes true counter flow.
Boiler efficiency 100 heat exported by the fluid water steam heat provided by the fuel 1.

Cop is expressed as.
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.
Cop thermal output btu hr power input kw 3413 btu kwh or.
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.
Boiler efficiency is in general indicated by either thermal efficiency or fuel to fluid efficiency depending the context.
Cop the change in the heat level of an area the energy consumed.
