Wolf FGB-K-28 condensing gas boiler, dual-function, wall-mounted 8616025

Modern heating with Wolf FGB-K-28 boiler

The Wolf FGB-K-28 condensing gas boiler is an advanced heating solution combining high efficiency with compact dimensions. It is ideal for both newly built and modernized homes, providing thermal comfort and savings. The device is dual-function, meaning it is responsible for both heating the rooms and producing domestic hot water. Its construction based on German engineering guarantees reliability and long life.

Efficiency and savings

Condensing technology allows for the recovery of heat from exhaust gases, which translates to higher device efficiency and lower gas consumption. The energy class A for both heating and domestic hot water confirms its energy-saving character. High CWU rated power (27.3 kW) ensures comfortable access to hot water even when using multiple draw-off points simultaneously. XL performance profile guarantees optimal operation in various working conditions. Additionally, modulated burner operation allows adjusting the power to current heating needs, further reducing operating costs.

Construction and installation

Compact dimensions (408 x 650 x 310 mm) make it easy to install the boiler even in limited spaces. Built-in components such as the expansion vessel, safety valve and condensate siphon simplify installation and reduce the number of additional components. Thanks to the universal air-flue connection (DN 60/100), the boiler is compatible with various chimney systems. The built-in weather compensator allows automatic adjustment of the room temperature to the weather conditions, and the ability to remotely control it using the Smartset application (optional) provides full control over the heating installation from anywhere. It is worth mentioning the aluminum heat exchanger – lightweight and efficient in heat conduction.
