Fueled by electricity, heat pumps are used to either heat or cool your home by transferring heat between two reservoir. In the warmer months the heat pump acts like an air conditioner, moving heat from inside your home to the outside. During winter, heat from outdoors is transferred to the interior of your home. Manufacturers believe that even on a 32* - Fahrenheit day it produces enough heat to warm a home. Dale tends not to agree with this and feels that this is when your home's furnace should come into play, unless you have heat pump with inverter technology and is designed to go into the negative temperatures.
