There are a lot of options for heating the room. The most famous are heating with a gas boiler , an ordinary stove or a coal boiler. And what did you hear about the electric duct heater?
What kind of beast is a duct heater?
An electrical duct heater is an appliance that serves to heat air in a room through a supply air system. It has pipes (channels) through which hot air circulates. It is by its heating that the channel heater is engaged. In the open metal case there is a metal spiral (TEN), which, under the action of an electric current, creates an electrical resistance. It subsequently converts the energy that has appeared into heat. By the way, this device is called an electric heater in another way.
The channel heater is used in industrial premises, for example, workshops, garages. This is a relatively inexpensive type of heating in the installation. By the way, in many models it is possible to set the required power. Experts recommend buying electric heaters only with built-in protection against overheating (thermostat). This will help to avoid the risk of fire.
Types of electric channel air heaters
Basically, these are standard products that differ little from each other. The most popular type is a round duct heater. The body is made of a sheet of steel in the form of a round tube, where there is a switching box with a metal spiral and terminals for connection to the elements of the electrical circuit.
The rectangular duct heater is respectively used as a heater in rectangular duct ventilation systems. It can be used as the main heater where this system is available, or as an additional heating device.
