A. The HP is designed to heat the air about 20 degrees each time the air goes through the system. A gas or oil furnace is designed for a 40-70 degree temperature rise as the air passes thru the furnace. So if you maintain 70 degrees in the home, a heat pump will put out about 90 degree air depending on the outside temperature. Since the normal body temperature is 98.6 degrees this 90 degree air feels cool to us.  In comparison a gas or oil furnace normally warms the air to between 110 - 140 degrees or higher and therefore it feels warm to us.  

A. A heat pump pulls heat out of your home in the summer, just like an air conditioning system.  In the winter, the heat pump captures heat from the outside air and transfers it to your home.  (Yes, even cold air has heat energy in it.)  A blower fan then pushes this heat through your ductwork and your vents.
