A. They are alternate fuel providers that may be able to save you money on the Natural Gas you use to heat your home. They sell you the NG at a fixed rate over the year. Duke sells you the NG at different prices thru the year based on their actual cost at the time of delivery.

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.
