Combination boiler (definition)

Combination boiler - This boiler, which is capable of operating on two or more types of fuel or performing several functions at the same time, such as heating and hot water production (DHW). This type of boiler can be equipped with several combustion chambers or burners, which allows the use of different types of fuel, such as gas, diesel, pellets or wood, making the heating system more flexible and economical.

Combi Boiler: Key Aspects

• Flexibility in fuel choice: The user can choose between different fuel sources depending on availability, cost or ease of use.
• Energy efficiency: Combination boilers can automatically switch between fuel sources, optimising the system's operation for maximum efficiency.
• Multifunctionality: Combination boilers are often used for space heating and hot water supply at the same time. Such boilers can have a built-in boiler or operate on the principle of flow heating.
• Examples of use: Boilers that can switch between gas and electric, or use wood and pellets, are examples of combination systems.

Advantages:

• Economical: Possibility of using cheaper fuel or its combination to reduce operating costs.
• Reliability: A backup fuel source ensures uninterrupted operation in the event of problems with one of the fuel types.

Main characteristics:

• Fuel types: most often, combination boilers operate on a combination of gas, electric, solid (wood, coal, pellets) or liquid fuel.
• Flexibility in use: Thanks to the ability to switch between fuel sources, a combination boiler allows you to choose the most affordable or cost-effective option depending on the situation.
• Efficiency: such boilers increase the overall reliability of the system, as they can be used in case of interruptions in the supply of one of the fuel sources.
• Application: combination boilers are popular in country houses and at sites where a constant supply of one type of fuel is not always possible.

Combination boilers allow you to reduce heating costs, provide backup fuel, and increase the energy independence of the system. They are especially useful in regions with unstable supplies of one type of fuel or when it is necessary to ensure flexibility in the operation of the heating system.
