Wolf FGB-28 condensing gas boiler, single-circuit, wall-mounted 8616023

Modern heating with Wolf FGB-28 boiler

The Wolf FGB-28 condensing gas boiler is a single-function suspended unit designed for efficient and reliable heating. Its compact dimensions and modern design make it ideal for various spaces, both in new and modernized buildings. Utilizing advanced condensation technology allows for maximum heat recovery from flue gases, resulting in lower operating costs and a reduced environmental impact.

The FGB-28 boiler stands out with its high efficiency (up to 94%) and the ability to work with different types of gas. Solid construction with high-quality materials – including an aluminum heat exchanger – guarantees long life and trouble-free operation. The built-in weather compensator and the possibility of remote control (with additional accessories) provide user comfort and optimization of the heating system.

• High efficiency: Condensation technology allows for achieving high energy efficiency, reducing gas consumption and heating costs.
• Compact dimensions: Enable installation in limited spaces, e.g., between kitchen cabinets.
• Versatility: Compatibility with different types of gas (natural gas, liquefied gas) provides installation flexibility.
• Durability: Construction with high-quality materials guarantees a long service life.
• Built-in safety features: Safety valve and expansion vessel ensure safe operation of the boiler.
• Control: The built-in weather compensator allows automatic adjustment of the heating power to weather conditions.

Construction and operating parameters

The Wolf FGB-28 boiler is characterized by a well-thought-out design that ensures easy installation and maintenance. It is equipped with a heat exchanger made of aluminum, which provides high thermal conductivity and efficient recovery of heat from flue gases. The modulating burner allows for precise adjustment of the heating power to current needs, which translates into energy savings. The device operates with a nominal diameter of the supply and return pipes of 3/4 inch (20), and the gas connection has a diameter of 1/2 inch (15). The minimum working pressure is 0.3 bar, and the maximum inlet gas pressure is 25 mbar. The boiler also has a built-in manometer to facilitate monitoring the pressure in the installation and an on/off control signal for integration with external control systems.

The use of a constant temperature difference between supply and return increases heat condensation, increasing the efficiency of the device and reducing scale buildup on the heat exchanger. This ensures that the boiler operates efficiently for a long time, minimizing the need for maintenance.
