How Air-Source Heat Pumps Work by the U. S. Department of Energy

Electric Air Source Heat Pumps

Air source heat pumps are a type of heat pump which utilize outside air as a heat source to heat or cool. Air source heat pumps are more efficient than oil, gas, and electric heating in mild climates but they are less efficient than ground source heat pumps. Why? Ground source heat pumps receive energy from the ground which is warmer than the outside air in winter. Air source heat pumps cost less to install than ground source pumps as they avoid the installation cost of a ground loop.

A heat pump transfers heat energy from a cooler to a warmer location. A heat pump uses the refrigeration process and transfers low temperature energy to a refrigeration loop, compresses the refrigerant to a high temperature, and transfers this heat to the hot water and heating distribution syste. In the summer this same energy removes it from the home. Systems normally range from a single 4kW unit to multiple units with a single controller producing around 300kW.

Daikin Altherma provides an air source heat pump system
that uses renewable low-carbon technology instead of conventional
fossil fuel boilers.
