Heating Equipment Specialized Center
Having a comfortable temperature environment for a living has been one of the essential needs of humans throughout history, and this need has become more prominent in the third millennium with the mechanization of life through the utilization of heating equipment in buildings and engine rooms.
Humans have always adapted their way of life to the changing seasons and have tried over the centuries to discover and create new methods to ensure their comfort in various conditions.
Heat is only one factor that creates comfort in our lives, but it often plays a significant role in our planning and economic costs, to the extent that we even pay attention to the geographical area and assess the fuel resources of that area to achieve comfortable heating.
The production and supply of various essentials and practical equipment for heating in buildings and central engine rooms have long been of interest to engineers and both small and large companies that manufacture heating equipment.
Over time, many factors have come together to enable the selection and use of the best product for creating comfortable heating in any building. In this article, we intend to introduce various types of heating equipment and facilities for buildings and boiler rooms, as well as how to calculate, select, operate, and use them.

Heating Equipment Introduction
The earth is warming up, and this phenomenon has reached its peak in the present era with the increasing production of greenhouse gases. However, it is no secret that climate and weather changes can lead to very hot summers and very cold winters, and we must always be prepared to face harshly cold winters.
1. Combi Boiler
One of the independent heating equipment in the cold seasons is the combi boiler, which can alone play the role of a small engine room in homes and office buildings.
In terms of placement, combi boilers are divided into floor-standing and wall-mounted types; based on the environmental conditions and the heat required for each unit, both wall-mounted and floor-standing combi boilers can be used in a building, with the difference that wall-mounted combi boilers are smaller and can be easily installed in the interior of the building, such as the kitchen.
Generally, the task of the combi boiler is to provide hot water for consumption and to provide the necessary heat for heating radiators in residential or office units. With a combi boiler, there is no longer a need for a central engine room, and consequently, the exorbitant costs of piping and supplying boilers, burners, etc. for the construction of building heating equipment and central engine rooms are eliminated.
Today, companies that supply combi boilers produce and manufacture their products with the highest performance and thermal efficiency, and with minimal fuel consumption (which is usually gas, diesel, or both).
They always try to gain more advantages in competition, and they also make consumers and builders independent of the construction of central engine rooms for buildings with less than 30 residential, commercial, and office units.
Wall-mounted and floor-standing gas combi boilers are divided into two categories: fan-equipped and fanless. The presence of a fan in combi boilers allows smoke and toxic gases from combustion to be easily discharged, even through horizontal chimneys.
Combi boilers can be equipped with one, two, or three heat exchangers and they have different efficiencies depending on the project needs.
Combi boilers with two heat exchangers use one heat exchanger to provide hot water for consumption and the other to provide the necessary heat for radiators.
Iran Radiator, Butan, Chauffage-Kar, Lorch, Baxi, Garm-Iran, etc. are Iranian-based companies that manufacture their products according to the latest standards and technologies of the world, and among the high-quality, non-Iranian manufacturers in this field, we can mention Vaillant, Ariston, Bosch, etc.

You can explore and compare various models of steel radiators from popular brands in the steel radiator section of the DamaTajhiz HVAC store.
2.3. Panel Radiator
Panel radiators are another type of radiator that is produced in a single piece of different lengths. These radiators are themselves a subset of steel radiators and transfer heat evenly. Panel radiators, in addition to their elegance and even heat distribution, are compatible with all types of decorations and can be installed from both sides.
However, it should be noted that due to the steel material of these radiators, there is a possibility of rusting and perforation in the long term, especially in very humid environments.
Aluminum, steel, and panel radiators share two things in common; first, they need to be installed by a technician, and second, they need a combi boiler or boiler to provide hot water inside them.
However, electric radiators have solved these problems, so that by simply plugging these products into an electrical outlet, you can enjoy their pleasant warmth.
2.4. Electric Radiator
Electric radiators are produced in different capacities and appearances; using these radiators in areas where there is a shortage of fossil fuels such as gas and diesel can be a suitable solution.
Electric radiators are also produced with a beautiful appearance that is compatible with the taste of users and consumers, and also with modern and extremely stylish designs, so the consumer can make the best choice based on the decoration of their home.

2. Water Tank
Hot water tanks are installed in central engine rooms to provide hot water for domestic and sanitary purposes. Their operation is as follows:
Coil Hot Water Tank: Coil hot water tanks are produced in horizontal and vertical configurations and feature a coil (a set of copper tubes shaped like the English letter U). The hot water from the heating system flows through the coil of the tank. The heat from the hot water is then transferred through the walls of the copper tubes to the water inside the tank, warming the water.
Double-Walled Hot Water Tank: Double-walled hot water tanks are installed horizontally in the engine room and have two separate walls. The first wall is actually the body of the main tank, which is surrounded by another wall. The water from the heating system circulates between the two walls, warming the inner wall, which ultimately leads to the heating of the domestic water inside the tank.
Note: When installing a horizontal coil hot water tank in the engine room, ensure that the coil can be removed for annual servicing and potential repairs.

These heating equipment are produced and supplied in various types of hot water unit heaters and steam unit heaters, and in wall-mounted, ceiling-mounted, and industrial forms. Unit heaters have advantages that distinguish them from radiators.
Due to having a ventilation fan, unit heaters have very high heating power. This high heating power helps to distribute heat evenly in large spaces and even with high ceiling heights.
Also, ceiling and wall-mounted unit heaters occupy much less useful space than other heating equipment. Unit heaters can throw air vertically and horizontally and have a high speed in heating the desired environment.
You can explore and compare various models of unit heaters from popular brands such as DamaTajhiz, Saran, Saravol, Saba Afarin, etc., and learn about calculating the required capacity in the unit heater section of the DamaTajhiz HVAC store.
7. Air Curtain (Air Door)
You might have seen and wondered why in many passages, banks, clinics, and generally most public places the entrance door is constantly opened and closed or open at all times. That's where an air curtain device is installed which throws air toward the floor with a relatively strong airflow.
You may not be able to see the device, but the air that is thrown down (or up) is clearly noticeable. An air curtain is a device that is usually installed above the entrance door and, by throwing air vertically towards the floor, separates and prevents the mixing of the air inside the environment and the air outside.
Some of the advantages of air curtains include preventing the entry of dust and airborne particles and preventing the entry of insects into the environment. Also, air curtains save energy consumption by preventing the escape of conditioned air from the relevant environment (cold or warm air).
You can explore and compare various models of air curtains from popular brands in the air curtain section of the DamaTajhiz HVAC store.
