Hot water boilers are equipment used for heating water, intended to supply hot water to homes for daily consumption and to ensure an efficient heating system in homes or commercial buildings. They can be powered by different energy sources, such as natural gas, electricity, wood or other fuels. Hot water boilers are essential for ensuring an efficient central heating system or for providing hot water for domestic use.

   Boilers can operate on the principle of heat exchange, transferring energy from the fuel to the water in the heating circuit. Depending on the type of fuel used, boilers can be classified into:

1.Gas boilers       – The most common and efficient, which use natural gas to heat the water.
2.Electric boilers – They use electricity to heat the water, often used in homes where there is no access to natural gas.
3.Wood or pellet boilers – They use solid fuels and are a popular option in rural areas.
