n.apparatus that extracts heat from a liquid that is at a higher temperature than its surroundings; can be used to transfer heat from a reservoir outside in order to heat a building
Aiming at the totaleconomyofthesystem, the economies of the engineand the gas-heatingpump are analyzed respectively. And the power and economy of gas-heating pumps are coordinated.
Much of the avoided energy consumption will come from the switch to carbon-neutral district heating (rural households will switch from oil, natural gas, and electric heating to heat pumps and biomass burners).
Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).
In addition, the U.S. has experienced an unseasonably mild winter, giving furnaces a welcome respite and their owners lower heating bills, making the higher payment at the pumps a little more palatable.
