The efficiency of a heat pump is determined by its coefficient of performance (COP). The COP is a measure of how much heat the heat pump can generate for every unit of energy it uses. A COP of 1 means that the heat pump is 100% efficient. A COP of 2 means that the heat pump is...

The air-source method is by far the most common—and affordable—way to operate a heat pump. And because it uses electricity to transfer heat, rather than burning fuel, a heat pump is much more energy efficient than most other heating appliances, typically using 50 percent less energy. ...
heat pump, is an efficient and convenient way for homeowners who don’t have ductwork to heat and cool their home. Unlike central air conditioning systems, which feed air through a system of ducts and vents, ductless systems are installed directly in the room they’re intended to heat or ...
unit's efficiency in moving heat from the air to the swimming pool water. Similarly, if it is cooling the pool, cleaning these coils will make the unit efficient at transferring heat from the pool to the air. A clogged coil minimizes airflow as well as the movement of heat in either ...
Additionally, previous energy-saving modifications to the home, such as upgraded insulation, energy-efficient windows and even ENERGY STAR®qualified roofing may also reduce the peak heating and cooling capacity requirements of the system that is required, potentially reducing cost. ...
THERMAL ANALYSIS OF AN AIR-TO-AIR HEAT RECOVERY UNIT FOR REDUCED ENERGY CONSUMPTION IN BALANCED VENTILATION SYSTEM The dual duct cold deck air-handling unit is actually less expensive because it does not require a heating coil and can be downsized to a small degree. Energy-efficient approach for...
How Does a Heat Pump Work? A heat pump is an energy-efficient alternative to a traditional heater because, unlike a furnace, heat pumps don’t generate heat. Instead, they extract heat from the outside and redirect it inside, and vice versa. ...

It’s not immediately obvious, but a Stirling engine is a reversible heat pump. If you put a heat source on one side and a cold sink on the other side, you will get mechanical power out of the shaft. What isn’t obvious, is that if you use an electric motor to put mechanical powe...
