Bosch and Junkers – older condensing boilers with built-in storage tank
This category includes the previous, still available generation of Bosch and Junkers condensing boilers with an integrated hot water storage tank – the CerapurAcu (ZWSB) and CerapurModul (ZBS) lines, including the solar variant CerapurModul Solar. A built-in storage tank means that the boiler and hot water heating are in one compact body, which saves space compared to a separate storage tank. These models are suitable especially for replacing an existing boiler of the same generation, or for customers looking for a proven Bosch/Junkers solution at a more favorable price.
