Hi friends! I made a post about the bath and there were many questions about the furnace, therefore I want to share information from personal experience, from conversations with cookies and forums. The photo except for the first is not mine, Thanks Tornet.
Furnaces for Russian baths are three species:
1.There in black - it is a focus of laid down cobblestones, in which the fire is burning. The smoke is produced through a dutched door, a window, a hole in the roof. After the stones fucked, wash the walls and soar. Who was soared in such, they say that feelings are indescribable.

2. Lent in gray - there are two types: direct and with channels. The direct-flow furnace is arranged in such a way that the stones lying on the grate grid are in fire, and the gases are output through the pipe. Channel bath oven has two valves. First herses the furnace herself, then the valve of the direct move is opened, the soot on the stones are burning further and it is bathed. In the bath, in gray, the walls are not covered with soot, but with the first sacrificing of water on the stones together with the ferry, the soot can fly out of the heaters, so you first need to give a sacrifice with an open damper.
3.There in white - the most late of three. In this furnace, the stones lie in the iron drawer or on a sheet of iron (stainless steel, cast iron), which heats up the fire. I do not give dirt, but the stones will not warm up to the temperature as in the stoves in gray or in black and the steam in it much worse.

The first and second options for periodic action, bath procedures can be started only after the end of the furnace must have a large number of stones (calculated depending on the volume of the steam and the amount of soared). The third option - continuous action has thin walls and a small amount of stones, can be fascinated in the process of use.
What to choose, how do metal furnaces differ for Russian baths from bricks?
Metal bath oven - Dignity:
-low price;
-Fast installation and commissioning;
- There is less space (but you need to retreat from the walls than that of bricks);
-From is heated;
-mal consumption of firewood;
- it is possible to fill in the process of use;
- No dirt.
Disadvantages of metal bath furnaces:
-From is cooled (it is possible to improve by reducing ceramic bricks);
-theless couple;
-dentity;
-Legled IR radiation;
-What is the likelihood of getting a strong burn when contacting with a furnace;
- not repaired;
- Drain designs do not dry and rot on faster.
Brick bunk - dignity:
- a large selection of structures;
-durability;
- Goty IR radiation;
-Lot couple;
- Pictures excessive moisture, more pleasant microclimate
- Male probability to get strong burns when contact with the furnace;
- Repair;
-The long time gives the heat to the room after the use of the bath, which allows the bath to succeed.
Brick bath oven - Disadvantages:
-high price;
-Etremunication;
-sons and complexity of commissioning (only on drying after masonry leaves from 7 to 14 days);
- heated;
- is a place;
-bid consumption of firewood;
- Periodically requires repair.
He stopped his choice on a furnace in gray, his grandfather was so, and wanted to have a chim fragrance with relative purity. The volume of the steam room is about 21 m 3, the stone in the furnace 15 boxes of 20 kg (mainly crimson quartzite from above, gabrodyabase from below and 1 talcchloride box), steam powerful and soft at the same time. The tank of 80 liters with hot water carried into the washing office, and put the heat exchanger in the oven, the water does not boil, and there is no extra moisture in the steam room. According to the Council of the Peak, the diameter of the chimney is 120 mm, with a small diameter above the thrust and soot accumulates less (burns) on the walls of the pipe, which reduces the risk of ignition. The excessive diameter of the chimney can lead to the ignition of soot with an explosion, as a result, the inner tube is first the damage and later burnout of the insulation and the damage to the outer one.
For a furnace, ceramic brick is needed full-length (no holes), a brand is not lower than 150 and not higher than 250, I took Tchaikovsky M150 with a bulkhead and choking the cheap (no need to take the cheapest and most expensive, because I did not meet the bricks for furnaces In ordinary, there is little that geometry suffers, he initially goes under the seam of 12 mm that for the furnace is not allowed, therefore it constantly has to be confused). The inner surface of the furnace should be smooth, all the projections are displayed on the outer wall with the subsequent grinding. Ceramic brick is not bandaged with chammatory - a different extension when heated (in the network there are many dearer where this rule is broken). When installing doors, grate, valves, metal plates, it is necessary to leave a gap of about 5 mm on the extension. The furnace (kernel) from the chamot is not bandaged with the furnace, there are also a gap to the extension from 5-10 mm. The mixture is better to take ready, for chamot and ceramics they are different. To simplify the extracts of its oven through the thickness of the stones, the pipe made of stainless steel with a diameter of 80 mm, which after the end of the furnace I closes the stone.

System assembly
And now about the errors. The main one - only the firebox laid out chammed bricks, it was necessary to fully make a chamotte chamber! As a result, uneven heating and crack around the perimeter where the border of the firebox. Not critical two mistakes: 1 This is one box of talcchloride-weak stone quickly burns, 2 in my furnace stones to move problematic. All good!
Good luck
