The furnace of the boiler water heating with their own hands , the instruction

No doubt that the greatest comfort in the Russian bath is achieved if the installed wood-burning stove with firewood crackling, a pleasant spirit and terrific heat of live fire.The only bad thing that the wood is sometimes required too much in order to melt the bathhouse and enjoy the process of purification.Significantly accelerate the room heating and cooking bath can help water heating boiler, which is integrated directly into the furnace.Such a tandem significantly increases the efficiency of wood-burning oven, and saves time and firewood.The basic idea is that the embedded copper even at small dimensions provides tremendous heat.Now let's talk about how to implement a similar improvement in the wood oven with improvised means in the short term.

Homemade water boiler of cast iron radiators

excellent in quality and efficiency of the boiler can be obtained from conventional cast iron radiators.As a base can take the radiator M-140.Its easy to find, as in large quantities they are taken to the scrap during dismantling and demolition of most of the old five-storey buildings.The capacity of each section of the radiator is 1.5 l of water, with a surface area of ​​up to 0,254 square meters.In assembly, when such sections 12 are combined, it is obtained already in the liquid volume of 18 liters and a total surface area - Q3.m. Not everyone is ready to pot, assembled from sheet metal, can boast such parameters under similar dimensions.The performance of the boiler the radiator may be sufficient for heating an area of ​​up to 100 square meters.m. So it is suitable, and the stock is still large enough for a regular bath.

it requires some modifications before using the radiator.First, we should get rid of the cardboard spacers between the sections.They are best replaced with asbestos cord impregnated with natural linseed oil with an admixture of graphite.So you can keep the gasket from burning at high temperatures.

While sections dismantled, they should be rinsed with a solution of hydrochloric acid 6% concentration, and after plenty of water.So they can be cleaned by a large layer of rust and dirt accumulated over many years of operation.

Assembly Procedure radiator repeats the process of disassembly, only in the opposite direction.To connect the sections used nipples provided with right and left-hand thread each side.Thus, as the section from below and from above simultaneously attracted turning of the pin.As soon as there is a gap of 2 cm between the sections wound asbestos cord impregnated and finally tightened nipples.

finished assembling all the radiator and waiting for drying varnish, joints should be checked for leaks by applying the radiator fluid under pressure.The only way to protect themselves from possible leaks during operation at considerable furnace temperatures.

connection pipes for flow and return are best run on a diagonal radiator.Thus, the water will smoothly flow around the new boiler.The two remaining openings must be closed with plugs.Pipes better to take the inch.On one side of the radiator is the right thread and connection problems will not arise.On the other, where the left-hand thread is better to use a pin and a box with sleeves.

Positioning a homemade pot should not be in the furnace, where the burning wood, and in the chimney chamber, which is located directly behind the camera of the furnace.Since the cast iron radiators are used, they should not be heated flames and hot gases, which are discharged from the furnace.

Radiator better positioned so that the tube comes out of it is perpendicular to the floor, as the supply of the return falls below the floor in the underground space.So it is possible to achieve better natural circulation of water during heating.

When assembling the sections, you can experiment to improve the design of the boiler obtained.As a result, it should have something similar to the image shown below.So there are examples of methods for the boiler and the location of its connection.Again, we should not forget that in the case of cast iron boiler should be positioned in the chimney.

Placing the boiler in the furnace?

most efficient variant of the boiler water is obtained by using as the material of the tube or sheet metal thickness of 3.5 to 5 mm.In this embodiment, the boiler can be placed directly in the hearth of the furnace and thereby maximize efficiency.The figure above shows a variant of the construction of the water heating boiler and its schematic position in the furnace.When using the pipe is better to give preference to seamless, and if such is not at hand, the seam should be available in addition to brew.

hot water from the boiler to the heating system should be placed exclusively at the highest point of the boiler.Location enter the return is not regulated, but the most logical to locate it at the bottom to improve water circulation.

When placing any boiler furnace should ensure that the gap between the outer walls of the boiler furnace and brickwork.This is necessary to compensate for the thermal expansion of the metal of the boiler.

When welding pipes, be sure to cut the chamfer on the contour of the cut pipe.This makes it possible to fill the entire weld pipe thickness and securely fasten items without the fear that they will disperse in the operation.

installing the boiler inside the furnace, it is necessary to adhere to the horizontal level.However, several possible departure from the rule in order to ensure the maximum height of the point O from the boiler feed.

Set the oven with built-in boiler

The best option would be for a bath furnace, which obviously, at the stage of construction, built into a specially prepared water boiler.In this case, the furnace gets its specific features in terms of design, which greatly improves the efficiency of the entire system and its compactness.

masonry bricks for ovens with steam boiler as follows:

1. lays the foundation of concrete with reinforcement.
2. used for masonry clay-sand mortar.It is best to soak the clay and sand at night.The lumps of clay and sand are ground.The next day, the two components are mixed in the ratio 1 portion into two portions clay sand.
3. top of the basement waterproofing layer is laid as a roofing material.
4. distribution layer of the solution uniformly and on a level on top of the waterproofing, and then you can start laying the first brick layer.
5. first circuit is formed of the blower and set the door for him.Then laid out on top of several layers of brickwork located grille separates the furnace and ash pit, which will collect the ashes.
6. When forming furnace is taken into account the size of the water boiler with the required gap between its outer walls and masonry in the furnace perimeter.On the contour of the first row of bricks in the furnace is formed by a side for mounting brackets.It will be fixed in the corners of the boiler.The side walls of the furnace sure to leave openings for pipes the output of the return and supply.
7. are derived wall chimney with mandatory formation of channels for dissipating excess heat and dumping ash and soot.
8. On top of the chimney laid out.Upon completion of all work can be connected to the heating system to the boiler and check it in action.
