Powerful and economical gas boiler for a private house

WOLF FGB-28 is an efficient gas boiler designed to heat water circulating through the home heating circuit. Thermal power of 27.3 kW allows using this unit for heating homes and offices up to 218 m². Thanks to the carefully thought-out design of the chamber, which ensures the most complete combustion of gas fuel, and the condensing principle of operation, the WOLF FGB-28 boiler is considered one of the most economical in its power class. Working at full load, it consumes only 2.63 cubic metres of gas per hour.

Features and Benefits

In addition to efficiency, this boiler is characterized by high reliability of components and assemblies, which ensures uninterrupted operation of the heating system. It has copper piping and a cast aluminium alloy heat exchanger, while the hydraulic block is made of composite materials. Built-in safety systems protect the equipment from almost all possible troubles, including an extinguished flame, lack of traction, a drop in gas pressure, freezing, etc.

In addition to private houses, Wolf condensing boilers can be installed in apartment buildings with shared chimneys. The manufacturer also guarantees their full compatibility with solar collectors and heat pumps. The boiler can be automated by installing an external temperature sensor (purchased separately). There is also the possibility of remote control of the heating system via a smartphone (there is a special accessory on the market that can be easily connected to the boiler).

Made in Germany

The stickers "Made in Germany", which are on all Wolf boilers, are not empty advertising. The equipment of this brand is made in the old fashioned way in the very heart of Europe by the hands of German workers. This is one of the reasons why Wolf appliances are noticeably more expensive than similar devices in the same power class from other manufacturers. But the quality of these boilers is appropriate — German, inspiring confidence.
