## What is a unit heater and what is its use?\r\nAra supplies wall heater units and ceiling heater units in two types of steam heaters and spa heaters. Unit heater is an environment heating device that can quickly heat the environment with existing water or steam by its blower fan.\r\n## The main components of the heater unit\r\n · Heat exchanger: The heat exchanger or coil unit heater is responsible for transferring heat from the heat source (hot water, steam or electricity) to the air. This converter is made of seamless copper and steel pipes.\r\n · Fan: is responsible for distributing hot air to the environment. This fan passes the air over the heat exchanger and sends it to the environment. The fan or propeller used in the heater unit is axial or centrifugal type.\r\n Vanes: The air outlet valve in front of the device, or the heater unit damper, transfers hot air uniformly and in different directions to the intended space.\r\n · Controller: The temperature and operation of the device is adjusted through this part. It is actually a kind of thermostat to adjust the fan speed and the amount of air coming out of the heater unit.\r\n · Body and structure: a metal sheet enclosure with electrostatic paint coating, inside which the coil and propeller and damper are installed.\r\n\r\nHeater unit components\r\n\r\n### Advantages and disadvantages of unit heaters\r\nUnit heater is used as an efficient heating system in large and industrial spaces such as sheds, workshops, sports halls and warehouses. In the following, we will take a closer look at the advantages and disadvantages of the unit heater.\r\n\r\n### Advantages of unit heater\r\n Fast and effective heating: One of the biggest advantages of the unit heater is its ability to heat large spaces in a short period of time. Using powerful fans, these devices spread hot air quickly in the environment, especially in spaces that need immediate heating, such as warehouses and production halls, unit heaters show high heating efficiency.\r\n Saving installation space: These heaters are usually installed on the ceiling or on the wall. This feature makes the floor space of buildings not occupied at all, which is very important in industrial and commercial environments. Installing a wall and ceiling heater unit at a height not only preserves useful space; Rather, it facilitates the distribution of hot air throughout the environment\r\n Variety in heat sources: Another advantage of unit heaters is their flexibility in choosing a heat source. These devices can work with hot water, hot oil, steam or even electricity. This diversity in heat sources allows the user to choose the right type of heater unit according to the conditions and access to energy sources. For example, in areas where there is access to boilers, a heater unit would be a suitable option, while in areas with strong electricity, an electric heater unit would be used. take it\r\n Accurate temperature control: heater unit
