Air Source Heat Pumps
An air source heat pump (ASHP) is a heating and cooling system that uses outside air as its heat source and heat sink. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. When used as a space heater air source heat pumps are usually called "reverse-cycle air conditioners".
In domestic heating use, an ASHP absorbs heat from outside air and releases it inside during winter, and can often do the converse in summer. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 80°C.

Famous quotes containing the words air, source, heat and/or pumps:
“Enthusiasm produces the most cruel disorders in human society; but its fury is like that of thunder and tempest, which exhaust themselves in a little time, and leave the air more calm and serene than before.”
—David Hume (1711–1776)
“There is no such source of error as the pursuit of absolute truth.”
—Samuel Butler (1835–1902)
“Coal is a portable climate. It carries the heat of the tropics to Labrador and the polar circle; and it is the means of transporting itself whithersoever it is wanted. Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comfort brings its industrial power.”
—Ralph Waldo Emerson (1803–1882)
“the rusty
Pump pumps over your sweating face the clear
Water, cold, so cold! you cup your hands
And gulp from them the dailiness of life.”
—Randall Jarrell (1914–1965)
