What is the fundamental operating principle of a heat pump that makes it more efficient than a resistance heater?
-
A
It generates heat through combustion more efficiently
-
B
It moves heat from one place to another rather than generating heat, delivering 2-4 BTU of heat for every BTU of electrical energy consumed
-
C
It stores solar energy and releases it as heat on demand
-
D
It uses a fuel cell to convert hydrogen into heat with high efficiency
