I am not a huge fan of heat pumps but I have had them in the past. There is no magic to a heat pump but it does in fact extract heat from the outdoor air and move it inside the house, put simply it is a air conditioner in reverse. We as human beings are very sensitive to small changes in temperature and there is plenty of heat in the outside air when we perceive it to be cold outside. There is no measurable heat at negative 460 degrees fahrenheit but at say 20 degrees fahrenheit there is a shit ton of heat available. Here is a quote from the Trane website,
"Think of a heat pump as a heat transporter constantly moving warm air from one place to another, to where its needed or not needed, depending on the season. Even in air that's seems too cold, heat energy is present. When it's cold outside a heat pump extracts this outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing heat from your home.
One advantage of a heat pump is that it moves heat instead of generating heat, giving you more energy efficiency. Also, it is powered by electricity, so you can save substantially on fuel consumption. For example, a Trane XL20i heat pump is among the HVAC industry’s most efficient, with a rating up to 19.00 SEER and 9.00 HSPF .
Note that heat pumps are best for moderate climates, and a supplemental heating source may be needed for lower temperatures. As a year-round solution for home comfort, Trane heat pumps can become a key part of your matched system. An independent Trane dealer can help you decide if a heat pump system is right for you."
