How do Heat Pumps Extract Heat from Cold Temperatures?
At absolute zero (-273.15 °C) particles have no energy and are completely motionless but as the temperature increases particles start to vibrate and kinetic energy is created. It is this energy that heat pumps extract and turn into heat. This is why heat pumps are often used in very cold conditions and are practical for heating homes in a huge variety of different climates. What may seam cold to us is still brimming with potential energy for the heat pump to extract!
