Electric heat exchanger efficiency. Heat and energy efficiency. Additionally by assuming countercurrent flows inside the. Where lmtd is the logarithmic mean temperature difference. The heat exchanger and other elements must be sealed perfectly to prevent leakage of carbon monoxide a deadly gas from the system.

Homeadvisor s complete heat pump or forced air furnace guide defines the differences between electric and gas heat pumps and gas electric propane and oil furnaces. In this paper the heat transfer efficiency is assumed to be 0 95 40. The cost savings associated with split ductless heat pumps is dependent upon a number of factors including the efficiency condition and location of. An electric furnace is the more efficient of.

Typically the heat transfer efficiency is between 0 6 and 1. For shell tube heat exchangers the overall heat transfer rate is defined as q u a lmtd. The process of installing a gas furnace requires specialized tools equipment and knowledge that even a seasoned diyer will not have. A heat exchanger is a system used to transfer heat between two or more fluids heat exchangers are used in both cooling and heating processes.

The use of electric heat pumps will actually save you between 1 000 and 2 000 anually in energy costs making it one of the most energy efficient air conditioning and heating systems out there. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. In this equation only the definition of mean temperature difference has been made more specific.
