Gas Condensing Boilers with a Built-in (Integrated) Tank

Gas condensing boilers with a built-in (integrated) tank, or hot water reservoir, provide constant and inexhaustible hot water heating comfort. The heating function is the same as with boiler-and-tank sets. Their main advantages are the small size and the way they heat hot water – that is, once the water in the tank runs out, the boiler works on the principle of instantaneous (flow-through) water heating. The best-selling boiler in this segment is clearly the Protherm Tiger Condens 20/26 KKZ 42.

Frequently Asked Questions

• What does a boiler with a built-in tank mean? The hot water tank is built directly into the body of the boiler, so there is no need for a separate tank or its connection – the solution is more compact and easier to install.
• What volume does the built-in tank have? These are usually smaller volumes (e.g. 40–60 l) compared to standalone tanks – for very high simultaneous hot water consumption (several bathrooms at once), consider a set with an external tank instead.
• Who is this solution suitable for? Mainly for apartments and smaller households where there is no space for a separate tank and normal hot water consumption at one draw-off point is sufficient.
• Can a different type of hot water preparation be chosen? Yes – we also offer boilers with instantaneous heating, boiler-and-tank sets with a larger external tank, or boilers with the option to connect a tank as needed.
