• Ability to replace a damaged section and easier maintenance compared to steel boilers.
• More affordable price and warranty for cast iron boilers compared to standard steel boilers.

MI3 Cast Iron Boiler Capacity Calculation 

• To estimate the required boiler power, first multiply the building’s useful floor area by 100 (kcal), then add 6,000 kcal per residential unit to account for domestic hot water. For example, for a building with 2,500 m² of useful area and 15 apartments, the required heating power is: 340,000 kcal = (15×6000) + (100×2500).
• To calculate the required cast iron boiler capacity based on number of units, floor area, building usage, presence or absence of a swimming pool, etc., you can consult DamaTajhiz experts.
• Usually, after the above calculation, up to 20% is added as a safety factor to the calculated boiler capacity.
• The most important consideration when using cast iron boilers is the working pressure limitation and the need to seal the joints between boiler sections after installation.
• If there are more than 6 apartment units, using 2 central heating boilers in parallel, each with 70% of the required capacity, ensures reliable heating and hot water supply.
• Installing a thermometer and manometer on each boiler to display water temperature and system pressure is mandatory.
• Also, installing an immersion thermostat with a temperature range of 30 to 90°C (or 30 to 110°C) for controlling boiler temperature and sending on-off commands to the burner relay on each boiler is required.

• Since all main boiler room equipment, including the central heating boiler, is installed on pre-built concrete foundations according to layout plans and exact locations, it is necessary to prepare the required concrete foundations according to defined dimensions and standards before installing main boiler room equipment, including the cast iron radiator boiler.
