Thermal Oil Heater Efficiency Calculation

Boiler efficiency is in general indicated by either thermal efficiency or fuel to fluid efficiency depending the context. 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. 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.

Thermal oil heater efficiency calculation.

It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output. Boiler efficiency 100 heat exported by the fluid water steam heat provided by the fuel 1. Use a smart thermostat. 3600 thermal power fuel calorific value boiler thermal efficiency.

Boiler heat loss is the loss of money if your. Even adjusting for efficiency heating oil still produces more heat per gallon than propane. Cop thermal output btu hr power input kw 3413 btu kwh or. Smart thermostats can also improve the efficiency of your heating and cooling system.

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. The comparison thus far has focused purely on the amount of heat equivalent amounts each fuel produces. Cop the change in the heat level of an area the energy consumed. Calculation assumes true counter flow.

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. Fluid properties are used at the average temperatures.

Taking a 10 ton oil fired boiler as an example its thermal power is 7mw. Liquids are considered incompressible. Air is assumed to be dry at atmospheric pressure and at zero elevation. 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.

Fluid temperature ranges from 40 f to 200 f. Cop is expressed as. Only sensible heat transfer occurs.
