The recent innovations have drastically influenced the development of Bainbridge furnaces, thus bringing in a sea changes in techniques applied. These adaptations are done to cater to the ever increasing needs of the humanity. As wood and coal are a scarce commodity now, the focus shifted, to use a much cheaper, abundantly available fuel for a furnace. The Bainbridge electric furnace eliminates the use of any fuel, as device basically converts the electrical energy supplied to it, to heat energy. The conversion mechanism is carried out by the heating coils. The coils produce high temperature when electricity is passed through them. The air near the coil becomes very hot. There are many mechanisms to direct this hot air to warm a certain part of the room or the whole house. As the electric furnaces have eliminated the need for combustible fuel, it is also called as the electric heater.
Depending on the method of distributing the hot air, there are variety of heaters. The heaters commonly found are the radiative types, the convection heaters and more recent one is the forced convection heater.
In a radiative heater, the heating element is enclosed in a glass bulb. The heat is directed away from the element, by making use of the reflectors. The heat ray is emitted in all directions. When these rays, hit the wall of the room, certain amount of heat is absorbed by the wall and rest is reflected again. This continues, and a certain area of the room is more warmer than the rest. Since it is more directed, the excessive heat can cause the objects in the vicinity to get ignited. These find a use for the garages, where only small select area needs to be heated.
The convection type of heaters are popularly called as the electric fire. In these systems, the hot air near the electric coils, moves up through the vent holes provided. Since the air in the room is cooler and dense, the air coming from the vent spreads through the room by the property of diffusion. This type of heating is more effective when it is used for a closed room. This takes longer time to heat the room and has no dangers of ignitions, as the warm air occupies the room slowly. There is no noise involved during the operation.
The forced convection heaters, make use of fans or blowers to move the hot air more quickly. The blower exerts more pressure on the air, making it more warmer. The heating achieved is more swift, because of the blowers employed. It is noisier when compared to convection type of heaters.
The electric furnace is slowly gaining popularity, over the typical gas fueled domestic furnaces. These are very famous for its independent operation. One does not need to switch it on or off. All the controls are done automatically by the device itself. The thermostat supervises the room temperature, and automatically switches on or off depending on the minimum and maximum temperature settings.
