Electric fireplaces are often placed in conventional fireplaces, which can then no longer be used for conventional fires. [1] They plug into the wall, and can run on a "flame only" setting, or can be used as a heater, typically consuming 1.4 to 1.6 kW to heat a 40 m 2 room.
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term flue meant the chimney itself. [1] In the United States, they are also known as vents for boilers and as breeching for water heaters and modern
The flue system is composed of two flues, the inner flue and the outer flue. The outer flue draws air into the bottom of the sealed firebox to allow for combustion. The inner flue draws hot exhaust gasses from the top of the sealed firebox and vents them directly to the outside of the structure through either an adjacent wall or roof.
Some fireplace units incorporate a blower, which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room.
The heat pump uses an electric motor to drive a reversed refrigeration cycle, that draws heat energy from an external source such as the ground or outside air (or the interior of a refrigerator) and directs that heat into the space to be warmed (in case of a fridge, the kitchen). This makes much better use of electric energy than direct ...

Lighting is also a good candidate for demand response , with many control systems providing the ability to dim (or turn off) lights to take advantage of DR incentives and savings.
