Condensing gas Boiler GB022-24 K H

Description

Condensing gas Boiler Buderus Logamax plus GB022-24 K H flue kit included

The wall-mounted gas condensing boiler, Logamax plus GB022 adapts to perfectly meet your heating and domestic hot water needs. It is particularly robust, thus reliably ensuring constant comfort.

The compact dimensions of the boiler allow a simple and flexible installation, being ready for use in a very short time. It is equipped with an advanced LCD screen for simple and quick control.

The Logamax plus GB022 boiler is particularly adaptable. With a high modulation ratio of 1:5, it effectively adapts to domestic hot water requirements, being very efficient from the point of view of consumption.

The equipment is characterized by a high power for the preparation of domestic hot water of up to 25 kW. Thus, there is always a sufficient amount of hot water available. In addition, the boiler has an extremely efficient operation
silent. In other words, you can shower at any time of the day or night without disturbing anyone.

With a compact and modern design, but at the same time robust, the Logamax plus GB022 boiler integrates perfectly into any living space, offering elegance to the place where it is placed. The hydraulic connections are not visible
under the equipment at the front and, with a depth of only 300 mm and a height of 710 mm, it can be perfectly integrated into the smallest rooms, such as the hallway.

Integration into an existing heating system is possible thanks to the modular design and the use of a control technology with proven efficiency.

Installation and maintenance operations can be carried out simply thanks to the compact design. The thermal unit weighs less than 36 kg and allows frontal access to the internal components. This saves time and reduces maintenance costs.

Advantages of GB022:

• increased efficiency thanks to a high modulation ratio of 1:5
• high power in DHW brewing mode
• compact design
• simple installation
• various installation possibilities thanks to the horizontal installation option (hydraulic connection)
• compatible with innovative systems thanks to the EMS interface
• elegant and functional design with an advanced LCD screen.

The delivery set includes:
