This tubular fireplace grate heater has a large surface area heat exchanger in a compact design, with a fan or blower (fans and blowers are not the same) to multiply the effect of natural convection. This is a very basic tubular blower that sits under a grate and heats the air being pumped through it from the heat of the coals.
An electric fireplace is an electric heater that mimics a fireplace burning coal, wood, or natural gas. Electric fireplaces are often placed in conventional fireplaces, which can then no longer be used for conventional fires.

An electric heater is an electrical device that converts an electric current into heat. [1] The heating element inside every electric heater is an electrical resistor , and works on the principle of Joule heating : an electric current passing through a resistor will convert that electrical energy into heat energy.
Portable fan heater A Japanese kerosene fan heater that burns kerosene for fuel. It contains an electric fan and computer controls. Electric fan heater. A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1]
Most air conditioners have a COP of 2.3 to 3.5. [4] When talking about the efficiency of heat engines and power stations the convention should be stated, i.e., HHV (a.k.a. Gross Heating Value, etc.) or LCV (a.k.a. Net Heating value), and whether gross output (at the generator terminals) or net output (at the power station fence) are being ...
