How a combination boiler works
A combination boiler combines the production of heat for radiators or underfloor heating with hot water preparation for household purposes. In contrast to systems with a separate hot water storage tank, the water in many combination boilers is heated as needed, which reduces or completely eliminates the need to store hot water. Thermostats and controls intelligently control the temperature so that energy is only supplied when needed.
The central unit contains burners, heat exchangers and control technology. Modern condensing boilers use exhaust heat to generate additional yield, while older models without condensing technology are less efficient. The exact mode of operation can vary depending on the fuel (gas, oil, solid) and type, but the basic principle remains the combination of heating and hot water functions in one device.
Types of combi boilers
Combi boilers are available in different versions: gas-powered combi boilers, oil-powered models, multifuel variants and modern electrified ones systems. Gas combination boilers are common in many regions because they are compact and efficient. Oil heaters are still an option in areas without a gas connection. Newer hybrid solutions combine fossil fuels with renewable sources or support solar systems.
