How to Repair Boiler
A boiler is a closed vessel, which is filled with water or other fluid for heating. The heated liquid vaporizes and then exits the boiler for to be used for various processes of some heating applications.
The pressure vessel inside the boiler is made of steel, or sometimes it is made of wrought iron. Stainless steel is never used for boilers, but it is usually used for the superheater section of the boiler.
In the live steam models, brass or copper is used for the firebox because it has higher thermal conductivity. However, the higher price of copper often makes it an uneconomic choice and cheaper substitutes are available.
In the Victorian age, the only material used in for boilers was the highest grade of wrought iron. In the domestic water heaters, cast iron is used. These types of heaters are also known as boilers, but they just produce hot water and not steam, and so they run on very low pressure.
The brittleness of the cast iron makes it impossible for the boilers to function properly. Earlier, boilers were the cause of many serious injuries and various property destructions due to poor engineering. The brittle and thin metal shells would rupture, while the poorly welded seams would open up, which lead to violent eruption of the steam. The large boiler explosions would demolish the entire building.
Sometimes, due to some problems in the boiler, it can stop functioning properly. Here are some simple steps on how to repair boiler.

Once you re-lit the pilot light, give sometime for the boiler to heat again. Keep a check on the amount of heat that comes from the radiator. If you know that there is enough heat, but not as much as before, then there is a problem with low pressure....
