What is a Unit Heater?
A unit heater is a heating device that is widely used for warming large areas such as workshops, warehouses, and gymnasiums. In certain cases, unit heaters can also be used for cooling purposes. Accordingly, their primary role is to generate heat. Essentially, a unit heater uses essential components such as a coil and fan to provide heating or cooling of the surrounding environment.

 Operating Mechanism of a Unit Heater
When a unit heater functions in heating mode, hot water or steam flows through coiled pipes, known as the coil, which is in a spiral configuration within the heater. Simultaneously, fans installed at the back of the coils draw air into the system. Once the air temperature changes, it is then dispersed into the space. When used for cooling applications, cold water circulates through the coils. Like in the heating process, the fans behind the coils transfer the cooled air into the environment. This increase or decrease in temperature relies on heat exchange. In this mechanism, air flows around the coil, transferring heat from the side with a higher temperature to the side with a lower temperature through the coil’s surface. For example, when warm air is required, a high-temperature fluid moves through the coils, while cooler air flows around them. Under such conditions, heat from the fluid is transferred across the coil walls to the air, thereby raising its temperature.
  
Components of a Unit Heater
Coil: The coil is one of the fundamental elements of a unit heater. Copper coils are used if the system is designed for water circulation. However, seamless steel coils are if steam is used.
Fan: The fan is positioned behind the coils and is responsible for drawing air into the heater, facilitating the temperature change process, and distributing the air throughout the desired area.
Body: The outer shell of the unit heater, known as the body, consists of all internal components and plays a role in the heat transfer process. Due to its importance, the body is generally constructed from steel of suitable thickness with a layer of oven-baked coating to enhance its strength.
Electric Motor: The electric motor is responsible for receiving electrical energy and sending it to other sections of the unit heater. Typically, the electric motors of unit heaters are in single-speed types; however, variable-speed motors can be used upon request.
Air outlet damper: These adjustable dampers are blades, located at the air outlet of the unit heater, allowing users to control the heated or cooled air based on their needs.
Heat Supplier: A boiler or hot water generator, installed in the boiler room, supplies the necessary hot water or steam for heating the air.
Chiller: If the unit heater is also used for cooling applications, a chiller system provides the required cold water to lower the air temperature.
Piping and Fittings: The pipes and fittings linking the unit heater to the heating and cooling sources carry the heated or cooled fluid from the heat source to the coils. After the temperature change, it is returned to the tank.
 
Different Types of HiWater Unit Heaters
Unit heaters are generally divided into several categories based on different factors, including:

Based on Type: industrial and residential.
Based on Installation Location: floor-mounted, wall-mounted, and ceiling-mounted.
Based on Airflow Direction expelled from the unit: Horizontal, vertical, and circulating.
Based on Fan Type: blower fan and exhaust fan.

Advantages of Unit Heaters
In general, using a unit heater offers a wide range of benefits. Some of the most notable and important benefits of unit heaters include:

In heating and cooling the environment, its strong airflow capability, combined with hot or cold air distribution, causes rapid operation, causing a quick desired temperature.
Even heat distribution.
Minimal space requirement compared to other systems with similar functionality.
These units perform efficiently not only in small spaces but also in large places with high ceilings.
When operating in heating mode, unit heaters do not require a chimney.
And so on.

 
Disadvantages of Unit Heaters
As you know, every product and device has its own advantages and disadvantages, and unit heaters are no exception. However, one key aspect is that engineers in the manufacturing field frequently provide solutions to solve these drawbacks. By applying these measures, the negative effects can be significantly reduced, while the advantages become even more prominent. Moreover, some benefits may make the drawbacks less noticeable. Overall, some of the disadvantages of unit heaters include:

These units cannot be used in areas where air moves freely.
It is not possible to install an air purification filter on these devices.
Unit heaters may not function effectively in environments with high humidity.
These units generate a high amount of noise.
