DamaTajhiz Double-Walled Horizontal Hot Water Tank 300 Liters

Guide to Selecting and Purchasing the 300-Liter Horizontal Double-Wall Hot Water Tank from Damatajhiz

The 300-liter horizontal double-wall hot water tank from Damatajhiz is a 300-liter tank designed to supply domestic hot water, suitable for use in apartments, residential buildings, offices, and commercial establishments. Please read the provided details and contact the sales experts in the heating equipment and boiler room section of Damatajhiz to experience a satisfactory and beneficial purchase from this dynamic company.

In general, various types of double-wall tanks are used to supply hot water for buildings by utilizing the hot water from the boiler. As the name suggests, the double-wall tank is made of two layers (constructed from high-quality galvanized steel), where the inner layer carries potable city water (through the inlet water pipe) and the outer layer circulates the hot water from the boiler. By transferring heat from the boiler water to the city’s potable water in the second layer, the double-wall tank provides hot and hygienic water for the building’s residents.
The 300-liter horizontal double-wall hot water tank from Damatajhiz is designed to be installed horizontally in boiler rooms of low-unit buildings. Double-wall tanks, besides being more cost-effective than coil tanks, do not require a separate circulation pump to circulate the hot boiler water in the heating layer of the tank.

Features of the 300-Liter Horizontal Double-Wall Hot Water Tank from Damatajhiz

One of the features of the 300-Liter Horizontal Double-Wall Hot Water Tank from Damatajhiz is its ability to heat a large volume of water in a short time, even without using a circulation pump (due to the gravitational flow of the hot boiler water), which makes it ideal for places such as residential apartments, offices, swimming pools, and any location requiring hot water. A challenge with double-wall hot water tanks is that if there is a small hole or leak between the two walls, it is usually impossible to repair, and fixing such tanks can be difficult.

• Body Material and Capacities
  The body of the Damatajhiz hot water tank is made from high-quality galvanized steel and is available in capacities ranging from 300 to 1500 liters.
• Double-Wall Tank Capacity
  Proper calculation and determination of the thickness of the galvanized steel sheet used in the construction of the double-wall tank, based on capacity, working pressure (water pressure inside the tank), and international pressure vessel standards, is crucial.
  Other factors that are important in determining the proper thickness of the sheet used in making both coil and double-wall hot water tanks include the working temperature (temperature of the fluid inside the tank) and the corrosion coefficient of the water used in the double-wall tank.
  

  Hot Water Tank Capacity for Quick and Approximate Calculations

  Building Type	Tank Capacity (Liters)
  Residential (up to five residents)	189 – 283.5
  Residential (over five residents)	472.5
  Apartment Complexes with Shared Tank	189 per apartment unit
  Hospitals (per bed)	46
  Schools (per student)	1 – 2
  Offices (per employee)	4.7
  Factories (with shower needs, per worker)	28.3

  To estimate the required capacity of the double-wall hot water tank (considering the number of units, usage type, demand factor, and simultaneous consumption coefficient for each unit), a capacity of 100 to 200 liters per unit is typically considered.
• Internal and External Wall Thickness
  The thickness of the galvanized sheets in the external wall of double-wall tanks ranges from 2 to 3 millimeters, while the internal wall ranges from 4 to 6 millimeters depending on the tank’s capacity.
  Note: The internal wall thickness of the double-wall tanks is generally thicker due to the higher water pressure entering the internal layer of the tank.
• Quality Control
  The galvanized steel sheets used in the construction of Damatajhiz double-wall tanks are among the best available, and are thoroughly inspected before entering the manufacturing process; after welding and completing the tanks, they are tested for quality by a supervisor before being shipped to customers.

Installation Tips for Tanks

• Installation of a safety valve (temperature and pressure) for all double-wall tanks is mandatory.
• If the internal wall of the double-wall tank or the coil of the hot water tank is punctured, water from the building's water supply system will leak into the heating system, causing overflow from the expansion tank on the building's roof!

Practical Tips for Ordering and Purchasing the Horizontal Double-Wall Hot Water Tank from Damatajhiz

• The minimum required height between the top of the water tank and the boiler room ceiling is 30 cm.
• Please note that the final diameter of the double-wall hot water tank is obtained by adding 10 cm to account for the outer wall.
• When purchasing double-wall tanks, pay attention not only to the capacity and dimensions but also to the material, sheet thickness, and warranty.
• Before ordering a horizontal double-wall hot water tank, make sure it can pass through the boiler room door and that there is enough space for installation and operation. If a tank with different dimensions is needed, determine the dimensions before ordering.
• Double-wall hot water tanks are more likely to start corroding at the dished ends (heads). This is due to micro-cracks and stress that are created during the manufacturing process of the heads, which are not visible to the eye. Therefore, using thicker sheets for the heads can extend the tank's lifespan by up to 5 years.
