Electric heaters are the devices which converts the electricity in to heat. Heating element in the electric heater is the electrical resistor and it works on the principle of Joule heating. Electric heaters differ in the way they deliver the heat to the environment, following are the types of electric space heaters:
Convection Heaters:
This heater operates by air convection currents circulating through the body of the appliance, and across its heating element. This heats up the air, causing it to increase in area. A convection heater may have either an electrical heater element, hot water coil, or steam coil.
Fan Heaters:
It contains an electric fan to speed up the airflow and this is also called as forced convection heater. This reduces the thermal resistance between heating element and the surroundings faster than passive convection, allowing heat to be transferred more quickly.
Radiative Heaters:
Heating element in these heaters is usually packaged inside a glass envelope and this element emits the infrared radiation that travels through air or space until it hits an absorbing surface, where it is partially converted to heat and partially reflected. This heat directly warms people and objects in the room, rather than warming the air. These are very useful in the places like garages and the basements.
Heat Pumps:
This uses an electrically driven compressor to operate a refrigeration cycle that extracts heat energy from the outdoor air and upgrades its temperature to a level high enough to use for space heating.
Storage Heating:
A storage heating system stores electricity which is available at night times and this electricity is stored in clay bricks which is released as heat during the day when required.
Domestic Electrical Underfloor Heating:
These systems are called as radiant heating systems. When the current flows through the conductive heating element, the material gets heated, then the heated material heats the flooring until it reaches the right temperature set by the floor thermostat. The flooring then heats the adjacent air, which circulates, heating other objects in the room by convection. This form of heating gives the most consistent room temperature from floor to ceiling compared to any other heating system.
The above are the various types of space heaters.
