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] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any fan, create a degree ...
Salamander heater. A salamander heater is any of a variety of portable forced-air or convection space heaters, often using kerosene or propane as fuel but also requiring electricity, [1] [2] used in ventilated areas for worksite comfort. Salamander heaters are most often found at construction sites. [3]
In the United States, Underwriters Laboratories' UL 1278 [11] (for portable electric space heaters) and UL 1042 [12] standards (for portable and fixed baseboard electric heaters) certify heater safety. Although the General Services Administration had Specification W-H-193 [13] for
The heating plate elements in this type of regenerative air preheater are also installed in a casing, but the heating plate elements are stationary rather than rotating. Instead the air ducts in the preheater are rotated so as to alternatively expose sections of the heating plate elements to the upflowing cool air. [1] [2] [3]
When filling a kerosene heater, there is an opportunity for the fuel to vaporize and create an odour in the air. This is why it is important to fill the heater in a garage or outdoors. When a kerosene heater is first ignited, it takes a few seconds to a few minutes for the fuel to mix with the air in the perfect ratio for complete combustion.
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 ...
