Efficiency within a model group will tend to vary by the size (capacity) of the unit. Some products like furnaces may also be affected by installation orientation (horizontal upflow or downflow) or even by the nozzle used in installation as is the case with and oil furnaces.

Jan 15 2020 · As defined in the Code of Federal Regulations (CFR)furnace means a product which utilizes only single-phase electric current or single-phase electric current or DC current in conjunction with propane or home oil and which (1) Is designed to be the principal source for the living space of a residence; (2) Is not contained within the same cabinet with a ...
Jul 29 2014 · Today DOE will take the first step toward establishing energy efficiency standards for new natural gas compressor units by issuing a Request for Information. Gas compressor units are estimated to consume over 7 percent of end use in this country and improved will provide meaningful savings and reductions in ...
However if the furnaces efficiency is 50 percent then the actual heating value of fuel oil is 140000 BTUs x 0.5 (efficiency) = 70000 BTUs. In other words when a gallon of oil is burned 70000 BTUs of heat is actually available to the user.
Example: A natural gas water heater with an EF of .57 and a fuel cost of $0.00000619/Btu 365 X 41045/.57 X $0.00000619 = $163 For electric water heaters including heat pump units
Energy in fuel enters the boiler (energy input 100 percent). From the boiler 4 percent of heat loss is through radiation and convection 18 percent is in flue gasses and 3 percent is in blowdown. Energy in medium (e.g. steam) exits the . output ( thermal ) is
