Boiler is made of 4 mm thick, high-quality gray cast iron produced by the VIADRUS company (Czech Republic). The heat exchanger is treated by inhibiting composition which prevents corrosion. The boiler doesn’t need to be plugged into an electric socket.
Separate sections are connected by means of the pressed nipples, pulled together with bolts and form the combustion chamber. The heat exchanger is characterized by heat resistance under high temperatures, high heat conductivity along with high efficiency which allows ranging it as advanced among its counterpart in the world.
