Condensing boiler, wall-mounted, single-function GCB-S57T CRYSTAL III 25 kW WKJ57T1000000/PLDT

Modern comfort and savings with the CRYSTAL III condensing boiler

The condensing boiler, wall-mounted, single-function GCB-S57T CRYSTAL III 25 kW is an advanced heating solution combining high efficiency with user comfort. It is ideal for both new and modernized installations, providing efficient heating and real savings. Thanks to the flame modulation technology, the boiler adapts to the current heat demand, and the soft ignition function guarantees quiet and reliable operation.

Efficiency and advanced technologies

At the heart of the boiler is a modern stainless steel heat exchanger, characterized by high efficiency and durability. The device has an energy class A, which translates to lower heating bills. The OPEN-THERM communication system allows remote control of the boiler parameters from the room controller – full control over the temperature in your home. The ability to work in a cascade system (up to 4 boilers) makes it a good choice for larger facilities.

• High efficiency: thanks to the use of flue gas heat, the boiler achieves high energy efficiency.
• Flame modulation: precise adjustment of power to current heating needs.
• Quiet operation: soft ignition function and fan optimization ensure acoustic comfort.
• OPEN-THERM system: remote control of boiler parameters for greater convenience.
• Cascade possibility: connection of up to 4 boilers to increase heating power.
• Cylindrical burner made of stainless steel: reduces NOx emissions (class 6), caring for the natural environment.

Construction and application

The CRYSTAL III boiler is equipped with a highly efficient circulating pump and a fan with smooth speed control, which translates to optimal energy consumption and quiet operation. The cylindrical burner made of stainless steel minimizes the emission of harmful substances, meeting strict environmental standards (class 6). The boiler is compatible with DHW tanks, a NTC tank sensor (cat. no. Z 0960 00 10 00) must be purchased separately. Thanks to its compact dimensions, it is easy to install even in small rooms.

The CRYSTAL III boiler is an investment in thermal comfort and energy savings – an ideal solution for every home!
