Space heater is a one of most important tools to endure coldness in winter. A space heater is a self contained device for heating an enclosed area. Space heating is generally employed to warm a small room in the house, and is usually held in contrast with central heating, which warms many connected spaces at once. The reason people choose space heater is because the cost of space heater is lower than the central heating. Space heater are usually portable or wall-mounted, and may use natural gas or propane as its energy source, but are most commonly powered by electric.
Space heater can be divided into two categories where one of them is that transfer their heat primarily by convection and another one is transfer the heat by radiation. The convection heaters, heating elements either warm the air directly or heat oil or another filler, which in turn transfers heat to the air. The example of convection heater is Big buddy heater. The air then warms the objects and people in the space. Convective heaters are suitable for providing constant, diffuse heat in well-insulated rooms. Oil heaters warm up slowly but do not reach dangerous surface temperatures while wire-element heaters that fan assisted can be reach desire temperature and can warm up the air more quickly. The example of radiation heater are Dimplex compact electric stove and Dimplex electric fireplace insert.
The Radiative heaters or halogen heaters usually comprise tungsten filaments in heat-resistant quartz envelopes, mounted in front of a metal reflector in a plastic case. They operate much like halogen light-bulbs, but radiate their energy primarily in the infrared spectrum. They convert up to 86% of their input power to radiant energy, losing the remainder to conductive and convective heat. The main advantage of radiative heaters is that the radiation they produce is absorbed directly by clothing and skin, without first heating the air in the space. This makes them suitable for warming people in poorly-insulated rooms, or even outdoors like a hall or garage.
The space heater that powered by electricity usually has ceramic or Nichrome heating elements, and may be fan-forced with a blower or a squirrel-cage fan to improve heat transfer. These often employ efficient heat pumps, which use reverse-cycle air conditioning to transfer heat to the inside from the outside. The other type of energy source is natural gas such as propane, butane, or liquefied petroleum gas. They may be convective or radiative, in the latter case by heating a matrix which then emits infra-red radiation. Gas heaters burn their fuel in air and produce carbon dioxide. In well-insulated rooms the oxygen concentration may drop and carbon monoxide may accumulate to toxic levels due to incomplete combustion. For this reason gas
heaters should be used only in rooms with adequate ventilation. But new technologies such as Big buddy heater and Portable Kerosene Heater have an ability to control the carbon monoxide level in the room.
As conclusion the space heater business should consider the type of space heater and its operating manual. This is important for the seller to suggest the most suitable space heater for their customer and provide the safety guide to operate the space heater. The knowledge from the seller will increase the customer trust and this will turn them into loyal customer. Beside that the basic technical skill about the space heater is really worth to help the customer if they have a problem with their
space heater.
Therefore I suggest 4 most compliance space heater:
Dimplex compact electric stove
Dimplex electric fireplace insert
Big buddy heater
Portable Kerosene Heater
