The boiler is welded from 4 and 6 mm thick steel sheets. The inner body of the boiler, which comes into contact with flue gases, is made of sheet metal with a thickness of 6 mm and treated with an anti-corrosion spray. The heat exchanger is welded steel pipes Ø57×4.5 mm.

The combustion chamber space is lined with 20 mm thick fireclay bricks. The cover casing is made of sheet metal with a thickness of 0.8 mm. The boiler insulation consists of NOBASIL material, the thickness of which is 20 and 40 mm.

Control

The electronic control AK 4000 is a new control unit for VIGAS boilers. It meets the requirements of simple operation. Already in the basic version, it is possible to connect a room temperature controller or an exhaust fan. It allows you to regulate the time and temperature of the boiler with a weekly program. It indicates fuel burnout, fuel control or malfunctions with its description. During the process of fuel gasification and combustion, the AK 4000 electronic control monitors temperature changes and, if necessary, smoothly increases or decreases the fan speed.
