What Is a Ducted Electric Heater?
A ducted electric heater is a device that heats air and warms objects by means of electric power.
Usually connected to a duct (a pipe that controls air flow), it raises the temperature of an object by heating and feeding air into it. It is often used for rooms such as workplaces and offices. They can be connected to the ducts of a heating and cooling system and incorporated into the central heating system of a building.
Many products use electric heating wires and are characterized by their simple structure. Because they use electricity, they are easy to install and can be used anywhere there is an electricity supply. However, it should be noted that if the unit price of electricity is high, operating costs may be high.
Some products can also circulate indoor air, helping to improve indoor air quality. Some products are also available that introduce outside air.
Uses of Ducted Electric Heaters
Ducted electric heaters are used in a variety of applications. The following are some of the uses of ducted electric heaters:
1. Residential heating
Ducted electric heaters are used as central heating systems in homes. They primarily distribute air through a central heating unit and ducts to heat different rooms in the home. This is a common heating method in cold regions and countries.
2. Commercial buildings
Ducted electric heaters are used to provide heating over a wide area in large facilities such as commercial buildings, factories, and warehouses. In these facilities, ducted heating systems can provide uniform heating for different sections of the building. They are also used in office buildings and hotels in combination with central air conditioning to provide a comfortable environment.
3. Public facilities
Ducted electric heaters are used to heat school classrooms, gymnasiums, and a variety of other facilities. They are often integrated into central air conditioning heating systems to maintain each classroom at the proper temperature. They may also be used to control room temperature in hospitals and medical clinics, and in public swimming pools.
Principles of Ducted Electric Heaters
Ducted electric heaters use electrical energy to heat air and distribute it through ducts to individual rooms in a building.
Usually, electric heating wires or electric heating coils are built in as heating elements. These components consume power and generate heat through resistance. The heat generated by these heating elements can heat the surrounding air.
Ducted electric heaters often incorporate a device called an air handling unit. The air handling unit draws air in with a fan or other device and regulates the air through filters and humidity control devices. This produces clean, comfortable heating air.
Heating air is delivered through ducts to each section of the building. Ducts are often concealed within walls and ceilings, and are structures that effectively control air flow by retaining heat as needed. Each room has an air supply outlet from the duct from which the heated air is released.
How to Choose a Ducted Electric Heater
When choosing a ducted electric heater, it is important to consider several factors. The following are factors to consider when selecting a ducted electric heater:
1. Location
The design requirements for ducted electric heaters vary depending on whether they are installed outdoors or indoors. Outdoor installation requires protection of power wiring, etc., and indoor installation is less expensive. After determining the installation location, select the product accordingly.
2. Power supply voltage
Ducted electric heaters operate on a specific supply voltage. It is important that the power supply voltage of the installation location match the operating voltage of the selected heater. Typical power supply voltages are AC110V or 1φAC110V and 3φAC220V.
3. Power
Power requirements for ducted electric heaters depend on the heating capacity of the heater. It is important to calculate the heating capacity based on the required heating capacity and select a ducted electric heater capable of heating sufficiently. Power requirements for electric heaters are specified in the product specifications.
4. Dimensions
Ducts for centralized air conditioning, for example, are designed based on the required heating and cooling capacity and the required air volume. The dimensions of this product are often chosen to match the installation space while conforming to the duct. Especially when installing in ceilings, make sure that the height and width of the product are within the allowable range.
