Condensing boiler, wall-mounted, single-function GCB-S57S CRYSTAL III 20 kW WKJ57S1000000/PLDT

Modern comfort and savings with CRYSTAL III

The TERMET CRYSTAL III condensing boiler is a proposal for those looking for an efficient and reliable heat source. This single-function model with a power of 20 kW is perfect for both newly built and modernized heating installations. Thanks to advanced technology, the CRYSTAL III boiler provides not only high comfort but also real savings in fuel consumption.

Efficiency and durability in every detail

The heart of the boiler is a modern heat exchanger made of stainless steel. Its construction guarantees high efficiency and corrosion resistance, which translates into a long service life of the device. A cylindrical stainless steel burner with low NOx emissions (class 6) takes care of the natural environment, minimizing harmful substances in exhaust gases. Additionally, the boiler is equipped with a highly efficient circulating pump and a fan with smooth speed control, which allows for optimal adjustment to the current heating demand.

• High efficiency: Thanks to condensation technology, the boiler utilizes the heat contained in the exhaust gases, resulting in lower heating bills.
• Durable construction: The stainless steel heat exchanger provides corrosion resistance and a long service life.
• Ecological combustion: The low-NOx burner takes care of clean air.
• Quiet operation: Advanced technological solutions ensure acoustic comfort.
• Cascade possibility: The boiler can work with other devices in a cascade system (up to 4 boilers), allowing you to increase the heating power.
• Open-Therm communication: Allows remote control of boiler parameters from the room controller – for full control over the temperature in your home.

Versatility and easy installation

Compact dimensions and the possibility of wall mounting make the CRYSTAL III boiler perfectly fit into various interiors. Electronic flame modulation allows for precise adjustment of power to current heating needs, and a complete safety system guarantees safe operation. Additionally, the boiler works with DHW tanks, which allows you to prepare domestic hot water (requires an additional NTC sensor – catalog number Z 0960 00 10 00). Thanks to this solution, you can enjoy the comfort of hot water all year round.
