Powerful combined (two-circuit) condensing gas boiler for heating and hot water supply. Able to provide heat and hot water to a separate residential building or apartment with a total area of up to 190 m2. Compared to classic double-circuit boilers, it has increased energy efficiency, which, with equal heat output, provides 7-9% gas savings. Such a significant effect is achieved due to the additional cooling of the combustion products, which allows you to extract the latent heat of condensation of water vapor formed during the combustion of natural or liquefied gas. Only reliable and durable materials are used in the construction of the boiler. The modulated gas burner and combustion chamber of the WOLF FGB-K-28 boiler provide an increased power control range, which has a positive effect o...n its efficiency. The built-in electronic control system allows you to easily and quickly adjust the parameters of the device. To optimize them, it is possible to connect an additional outdoor temperature sensor (not included), and when using the iSM7e remote control and monitoring module (sold separately), the user gets access to the settings via the Internet from a PC, laptop or smartphone. Thanks to the low-noise circulation pump, closed combustion chamber and forced smoke extraction, the boiler can be installed in residential areas. Made in Germany, backed by a two-year official warranty.

FAQ: 10 frequently asked questions about heating boilersAnswers to common questions in the section "heating boilers"

The double-circuit gas boiler WOLF FBG-K-28 is tasked with providing heat supply to residential and industrial premises up to 195 m², as well as preparing hot water for the water supply circuit, heated to a maximum temperature of about 65 °C.

Internal hardware

“Under the hood” of the boiler there is a closed combustion chamber with a forced flue gas exhaust system, a low-noise circulation pump and two separate heat exchangers(stainless steel for the DHW circuit and aluminium for the heating circuit). In addition, the compact form factor contributes to the "settlement" of the model in residential areas — the boiler fits into a niche with dimensions only slightly larger than 650x408x310 mm.

Intuitive controls

The boiler is assembled from high quality components, is notable for its ease of installation and ease of operation. Optionally, an outdoor temperature sensor or, for example, an iSM7e remote control module can be connected to it. Together with the latter, it becomes possible to control the operation of the device remotely using a smartphone, tablet or laptop. In addition, the auxiliary module simplifies the work of maintenance personnel.

economy

The products of combustion in the boiler are subjected to deeper cooling, which makes it possible to extract from them the latent heat of water vapor condensation. As a result, the model turned out to be 7-9% more economical than traditional design devices — the maximum gas consumption in it is 2.63 m³ / h. Finally, it is worth noting the vaunted German quality of the unit, which acts as a guarantor of its long-term service to guard the warmth of the hearth.
