Electric heaters generally have the following components. They are housing, a resistance and a control device that is used to protect the device from overheating. There are some heaters which also have a ventilation mechanism which in turn is used to direct the heat that is produced.
It is true that electric heaters should be installed by qualified professionals but when compared to other options, the installation of electric heaters is comparatively easier. Only a few accessories are required for the installation of electric heaters.
Electric heaters are overall less expensive when compared to oil or natural gas heaters. They require less expensive equipment and they have a cheap installation cost. However, there are some who are of the opinion that the electricity used in electric heaters pushes up the running cost. But when compared with other kinds it will be seen that from all aspects, using an electric heater is cost-effective. It needs to be mentioned here that electric heaters have a lower maintenance cost as well.
Another advantage of electric heaters is that they are hundred percent efficient. This means that the amount of power that is put into the system is converted into heat. On the other hand natural gas and other forms of combustion systems do not provide such a kind of efficiency and the tendency is such the efficiency decreases as these systems become old.
