Types of Central Heating Hot Water Boilers with Components and Parts
Central heating hot water boilers (CH Boilers) are key components in heating systems for residential, commercial, office, and industrial buildings. These devices heat water using various energy sources such as gas, electricity, or fossil fuels, and then distribute heat through piping to radiators, fan coils, and other heating equipment. Given their critical role in providing adequate heating, choosing and using them requires careful review of technical and performance aspects.

1. Steel Boilers
Structure & Performance: Made from high-grade steel alloys with excellent resistance to high pressure and temperature for high-capacity systems. Thicker walls extend lifespan and improve energy efficiency; anti-corrosion/thermal coatings protect against environmental effects.
Application: Ideal for large industrial projects, large commercial buildings, and sites requiring stable, continuous heat supply.
Advantages: Long lifespan, pressure/corrosion resistance, suitable for large/industrial systems needing high reliability.
2. Cast Iron Boilers
Structure & Performance: Traditionally cast iron with strong thermal properties; modular sections allow easier maintenance and replacement.
Application: Common in small-to-medium residential and commercial buildings seeking reasonable efficiency and low maintenance costs.
Advantages: High rust/corrosion resistance, more affordable than steel, simpler installation/maintenance, suitable for small–medium scales.
3. Condensing Boilers
Structure & Performance: Recover latent heat from flue vapor to raise efficiency and lower fuel consumption.
Application: Favored in modern/green projects prioritizing energy savings and environmental impact.
Advantages: Very high efficiency, reduced fuel use and emissions; ideal for eco/economic designs.
4. Electric Boilers
Structure & Performance: Heat water using electricity; environmentally friendly, no fossil fuel, no complex venting, easy to install.
Application: Where natural gas access is limited or emission reduction is a priority.
Advantages: Easy installation, clean operation, no chimney, simple upkeep.

2) Key Points for Selecting, Installing, and Maintaining Boilers
Heating Capacity: Must match the building’s heat load. Incorrect sizing increases energy use, lowers efficiency, and shortens lifespan.
Material Quality: Durable steel/cast iron with anti-corrosion coatings directly affects service life and performance, preventing premature failures and costs.
Safety Systems: Equip boilers with safety valves, high-limit thermostats, and auto shut-off to prevent incidents (explosion, gas leaks, electric shock).
Installation: Professional installation and proper site/venting ensure optimal performance and safety.
Periodic Maintenance: Inspections, heat-exchanger cleaning, and safety checks increase lifespan, reduce energy use, and prevent sudden failures.

3) Specialized Customs Clearance Notes for Hot Water Boilers
Tariff (HS Code)
Hot water boilers fall under HS Code 8403.10.00 for central heating water boilers. Knowing the code is essential for accurate import duties and clearance costs.
Required Documents
- Invoice: main document showing price and sale details.
- Bill of Lading: shipping document specifying dispatch and delivery details.
- Certificate of Origin: identifies the production country.
- Customs Declaration: complete info about the goods and import conditions.
- Inspection Certificate: may be required to confirm quality and international compliance.
| Item | Short Description | HS Code |
|---|---|---|
| Central Heating Hot Water Boiler | Hot water boiler for central heating systems | 8403.10.00 |
Final classification depends on capacity, fuel, working pressure, heat-exchanger/condensing type, and manufacturer documents.
4) Exporting and Importing Countries of Hot Water Boilers
Importers
Iran imports mainly from China, Turkey, Germany, and Italy due to their expertise and product quality.
Exporters
Iran is expanding production capacity and exports to neighboring and some Middle Eastern countries. Although volumes are lower than imports, the trend is rising with improved technology and quality.
5) Import and Export Volume of Hot Water Boilers
Imports: High volumes due to increasing demand for quality heating systems and growth in construction/industrial projects; demand rises in colder seasons.
Exports: More limited, depending on quality, price, and market demand; expanding as domestic product quality improves.
Clearance of specific goods is possible if special permits are obtained.
