Square brick furnaces, called "Dutch" plastered, faced with tiles or armored with a sheet, have also been replaced by armored round furnaces "Utermarks" , with a very strong structure and high thermal efficiency. In year 1820 the inventor Utermark developed the first technical design of this furnace in Russia.

The Utermark stove had a fire at the bottom, which was sealed with a cast iron plate, with an opening for one channel in the furnace. The exhaust gases passed through all six channels sequentially, until it connects to the chimney at the top. Inside, of the furnace, above the furnace plate there was a vertical sheet metal pipe extending above the vault and built around with bricks. The tube was open at the top and bottom, the lower part above the fire plate had small side openings for air circulation.
The mantle of the furnace consisted of several annular sheet metal elements, vertically riveted or welded, which were connected to each other, stacked on top of each other, on a groove with a depth 6-8 cm and rested on an embossed seam around each ring. Often, narrow metal bands were used at the joints, pulled off with a bolt and a nut.

At the time of the design of the Utermark furnace, there was a general opinion, that the most preferred design is a multi-channel oven with several channels, along which the gases go up and down in turn. Such a construction was aimed at obtaining the longest path of exhaust gas circulation in the furnace. Having low efficiency and outdated design, the "Utermark" furnace was distinguished by unmatched durability and a very high heat capacity. The "Utermark" type furnace was also used in Poland in military barracks.

Despite this, that the "Utermark" furnace had many disadvantages compared to current concepts, however, it was so widespread and appreciated in Russia, that for its application, buildings with appropriate dimensions and location of rooms were designed.
