Before the onset of cold weather, many ownersSuburban real estate are starting to think about how to make the house warmer. This can be achieved in various ways by which heat losses are minimized. In the absence of the opportunity to use natural gas from the central highway, you can resort to alternative sources of heating. One of these devices is the oven with a water circuit. You can do it yourself.
Among the main advantages of this design should be highlighted:
The cost of the heater will bebelow other devices. If you use the available materials in the manufacture of the furnace, the price can be minimized. The fuel for this design can be very different, namely:
The equipment functions usingnatural circulation of the coolant. The device is not tied to electricity, so there is no need for a power supply. But one of the main advantages is that you can make such a device yourself. It will be much cheaper than the factory model.
In addition, the device can be made easier thanequipment manufactured in streaming production. Sometimes this eliminates the need to install a more complex foundation. This not only reduces labor intensity, but also cash costs. Sometimes the last factor is one of the main factors for craftsmen, who decide whether to visit the store to purchase a heater or to work on their own. In the latter case, you can use the materials that are found in any barn.
Factory furnace with a water circuit costsquite expensive. Variants of its manufacture can be considered in more detail to cope with the work on their own. Quite an important step is the choice of form. If the stove has the shape of a cylinder, then a pipe or a metal barrel may lie at the base. When the product has the shape of a rectangle or square, for its manufacture is usually used 5 mm steel sheet.
The design should include two zonesthe first is the area of the combustion products, while the second is the zone of the furnace. If you plan to use for a stove with a water circuit for heating private firewood, the diameter of which will be quite impressive, it is necessary to make a hole in the firebox area, the cross section of which will be 40x40 cm or more.
When fuels are small pieces of woodor coal, the dimensions of the flue holes are reduced twice. Smoke can be removed at the back of the firebox. In this case, during installation, it is necessary to provide an angle of inclination of the chimney. It should be 30 grams. This is done to ensure good traction. In a different scenario, the smoke will not be effectively discharged into the chimney and will enter the room.
The heat capacity of the stove, if necessary, you canto increase, having strengthened several edges on each side. For this, metal 5 mm plates are used. They are located perpendicular to the wall plane. This will increase the heating surface of the heater and increase heat transfer. Some enclose the construction with bricks, because such a wall is capable of retaining heat longer. This approach allows for fire safety.
Before you make a stove with a water circuit, youmust prepare the pipe. Its diameter should be 300 mm or more. The wall thickness is 5 mm. You can use metal sheets of the same thickness. For removal of smoke should use a pipe with a diameter of 120 mm. The wall thickness should be 3 mm. This thickness of the chimney is explained by the fact that the temperature of the exhaust gases is lower compared to those that are maintained in the combustion chamber. To spend money on more powerful designs is not necessary.
To simplify the operation of the furnace, care must be taken to have an ash collection box. It is installed in the ash pit. Among the tools should be highlighted:
The furnace with a water contour gathers on technology,which provides for the connection of the bottom with three walls. Front is not installed. The bottom should be at a height of 30 cm, which will reduce the risk of floor heating. The furnace should be equipped with metal legs, which are welded to the base. A prerequisite will be the connection of elements at right angles. Parts and joints are made by welding machine.
In the partition between the furnace and the blowerseveral gaps are cut to remove ash. It is necessary to retreat 5 cm from the walls of the stove. The blowing opening should be 3 cm less than the space of the blower. Along the perimeter in the next step, you can weld the front part of the structure. It is pre-made openings for doors. On the sides of the openings, awnings are welded, on which doors for the blower and the firebox are installed.
Doors are equipped with latches or bolts.As soon as welding of the elements of the stove is completed, it is necessary to check the joints for defects. When making a stove for a house with a water circuit, at the last stage you will have to weld the chimney pipe and the upper part of the structure.
As one of the main elementsheating device protrude water circuit and heat exchanger. It connects to the heating system. Its design can be different, and it is made of hollow steel pipes, as well as sheet steel. Its thickness is 5 mm.
The water circuit provides for:
Система водяного контура монтируется по the algorithm, which involves the installation of radiators. In the next step, you can begin to connect the pipe. They go to the batteries from the furnace. The inlet and outlet shall be control valves.
After you can start the installationexpansion tank. This element requires that the water does not break pipes when heated. The excess hot liquid will flow into the tank, from where the coolant will return to the pipeline when it cools.
A brick oven with a water circuit can bemade to your size. However, the article deals with an example with the following parameters: 1020x1160 mm. The height of the structure is 2380 mm. The dimensions of the heat exchanger are 750x550x350 mm. This part of the device is made of sheet steel and placed in the firebox. The hob will be used exclusively for heating food. The heat output of such equipment may be 5.5 kW. This is true if the firebox is carried out 2 times a day. When operating in enhanced mode, the above parameter reaches 18 kW. This allows you to heat the room up to 200 m2.
Before making a furnace for giving with a water circuit, you need to prepare:
Without the chimney, the amount of redsolid brick will be 710 pieces. Chamotte refractory bricks of the brand SHA-8 is prepared in the amount of 71 pcs. The dimensions of the furnace door should be 210x250 mm.
If you need a wood stove with a water circuit,You can build it from bricks. Before starting work, it is necessary to manufacture a heat exchanger. The walls facing the flame should consist of 5 mm sheet steel. The outer walls, which will have a much lower thermal load, can be made of 3 mm sheets. Behind it, leave a 50 mm gap for the gases to exit the firebox.
Using a seamless steel 40mm tube, youYou can make a heat exchanger outlet. The product is welded at the top. Another outlet is made of the same pipe that is installed at the lower point of the heat exchanger.
The furnace with a water contour for home heating canbe made of bricks. Before the beginning of the laying it is necessary to build the foundation. The first row will be solid. It is important to keep horizontality and squareness. At this stage, 36 red bricks are used.
The formation of the ash chamber begins with the layingsecond row. It is necessary to install a door, the size of which will be 140x250 mm. At the same time, 31 whole bricks and one half are involved. The number of bricks in the third row remains the same. When laying the fourth row, the firebox should be formed. It uses 11 fireclay bricks and 21 red.
To install grates in fireclay bricksit is necessary to make cuts. At the stage of formation of the fourth row in the grooves fit grille. To ensure thermal expansion, a 5 mm gap should be left.
A heat exchanger is installed at the bottom of the firebox.For thermal expansion of the heat exchanger when laying the next row, you must leave a 5 mm gap. Behind it is left a space that connects to the horizontal channel. Two doors are installed in the next stage. They will have a square shape and a side of 140 mm.
В пятом ряду будут задействованы 3 шамотных bricks and 14 red. When building a stove with a water circuit for heating a house in the sixth row, a horizontal channel is formed. It should be separated, and the hole left in the previous row will increase traction. At this stage, the door is mounted. You should use 15 red bricks and one half. Another fireclay is involved.
Using the scheme, it is necessary to form the seventh row.This will use 15 red and 2 fireclay bricks. Shut the door of the furnace you can when laying the eighth row. To do this, use a strip whose dimensions are 50x5x400 mm. In this row will be 6 fireclay and 11 red bricks.
In the ninth row, you can release the supply pipethe boiler. In the tenth row of products are produced inside, so the space will be narrowed. Cast iron plate should be installed in the eleventh row. In the area of the opening in the cooking chamber should install a corner. You can begin to form the cooking chamber in the twelfth row. Cooking cast iron surface should be removable. The entire width of the available width should be increased vertical channel in the 14th row. To clean it installed square door.
Фасад варочной камеры следует перекрыть в 16-м the row. To do this, use a steel strip and corner. The overlap of the facade of the cooking chamber is completed in the seventeenth row. Complete the overlap of the cooking chamber can be in the 19th row. The base of the upper ducts can be formed in the 20th row.
Furnace overlap can be prepared in the 22nd row.The smoke valve is installed and adjusted in place after completion of laying the 24th row. At this building a long-burning furnace with a water circuit can be considered complete. The chimney is implemented individually, as this takes into account the overlap and type of house, as well as the truss system.
When you create a stove will need welding.The body will have a double shirt. This place is the most difficult, so you can use one of two options. The first involves the manufacture of the furnace separately from the whole structure. The coil is inserted into this part. The finished element is then connected to other parts of the device.
Второй вариант предполагает подготовку structures without top roof. Inside the next stage is inserted the jacket of the shirt and fixed. Only then can you install the coil, which is prepared in advance. The second option allows you to change the assembly scheme. First, the coil is installed, and after - the shirt. For its inner shell is used a thicker sheet of metal. This parameter should be 5 mm, since the material will be in the vicinity of open fire and exposed to high temperatures.
The stove with a water circuit can be supplementedcirculation pump. It is used if the firebox is located slightly above the radiators or on the same level with them. Under such conditions, it is necessary for the reason that the work of the system is carried out according to the laws of physics. The heated water rises to the top, and the cold is at the bottom. This fluid property is used in systems with natural circulation.
If the coil is above the radiators, thenthe circulation is disturbed, and the water stops moving, while the coil boils. In order to eliminate problems, a pump is installed that increases the efficiency of the fireplace. The equipment is located in the basement or outside the house.
Cast iron furnaces with a water circuit are also quite popular. You can buy them in the store. The price of the above model is 49,200 rubles. It is near-wall and can heat up to 240 m.3 premises The heated area is 89 m2. At the heart of the furnace and the furnace itself is cast iron.
The model provides for a water circuit.The door has glass. The chimney is displayed on top. Serbian company manufactures wood stoves. One of the versatile and powerful is the device that was mentioned above. Among the advantages should be distinguished water circuit. With it, you can heat adjacent rooms. This device is made of heat-resistant cast iron and boiler steel.
In the production process using technologyfigure casting. The stove boasts not only high power but also an efficient design. A sauna stove with wood with a water circuit has a heat output of up to 12 kW. Oven and hob in the design there. The diameter of the chimney is 120 mm. The height, width and depth of the structure are 946x493x540 mm, respectively. This equipment weighs 155 kg and is black.
The efficiency reaches 78%.The equipment is universal and is combined with any style of decoration of the room. It is possible to use the device for functioning indoors. Heating is provided by the transfer of thermal energy to the walls of the furnace and the glass of the door.
Without the help of experts you can handlemanufacture of a furnace for testing. The basis of the gas cylinder will form. Details are welded to each other by arc welding. Among the tools and materials you will need:
The gas cylinder must have a capacity of 50 liters.The chimney is made up of pipes whose wall thickness is equal to the limit of 2 to 3 mm. The burner is also made of pipes. At the first stage, legs should be welded to the furnace body. They can be made of any suitable metal. The length of these elements make up the limit from 20 to 30 cm. Then you can proceed to the installation of the case. Using an angle grinder, you can cut holes that will be 50 cm from the floor.
Making for giving the furnace with a water contourLong burning, you will need to drill holes for the batteries and connect the parts of the pipe and equipment. The radiator is usually installed closer to the exit. For natural blowing, make 5-cm holes that will be located at the top of the pipe. It is important to provide a waste oil extraction system.
Перед тем как проделать отверстия для батареи, you must take the phone. It is important to foresee the place where the liquid will fall. If the device is installed in a private house, then they can make a drain hole. The entire system will be assisted by water in the circuit. Without it, cycling will break, and equipment will malfunction.
Making the furnace at work with watercontour, you will need to install it on a non-flammable surface. The walls around you need to beat the heat-resistant material. In the place where the device will be installed, there should be no drafts, since the flame can spread to combustible materials. There should not be flammable objects nearby.
Масло, используемое в работе печи, должно быть cleaned up. When the fire burns intensively, it is not recommended to add oil to the furnace. Before igniting, make sure that the chamber is 2/3 full. Top up with solvent or gasoline to start the burning process. Under these conditions, oil will evaporate. It is not recommended to leave the unit for a long time without supervision.
If you want to lay out a stove for the house with watercontour, then you can start to do it from scratch. Another option is to install the heat exchanger in the folded device. It can be represented by a stove or fireplace. The second method seems simpler, but in fact it is more laborious. The laying can be carried out from a ceramic red brick. Burnt products should not be used, as well as unburned. From normal, you can distinguish them by color.
The former have an almost crimson hue, whereasthe latter are light pink. The smoke channel is better to lay out of fireclay bricks, as it is highly refractory. Long burning stoves with a water circuit must have a foundation. To do this, at the bottom of the pit, you can lay crushed stone, rubble and brick battle. Layers are well compacted. The prepared "cake" is filled with cement mortar. This surface can be used for laying bricks in two layers.
The base must be closedwaterproofing material. For this, not only roofing felt is excellent, but also parchment. After completion of laying the foundation rises a few centimeters above the floor. The main difference of the cooking furnace with a water circuit is the presence of a heat exchanger. In the firebox, in the chimney and the cap is located coil. In this case we are talking about non-current devices. Most often carried out installation in the firebox.
During heating, the coil walls expand.To compensate for this process, leave a gap between the coil and the walls of the firebox. When laying the furnace, it is necessary to provide for the possibility of dismantling the plate to clean the register if this part is clogged with ash or combustion products.
Described heating furnace with a water circuitwill have a high efficiency. The same factor causes one nuisance: in the cold time, the equipment will work perfectly, warming the house, but the main problems may arise with the onset of heat. Use the device when connecting to the water circuit in the warm season.
This is due to the fact thatcoolant in radiators will be provided with the same intensity. If you turn off the radiator system, it will not save the situation, because the heat exchanger inside the furnace will heat up. From the effects of steam oven can simply collapse.
Печь-камин с водяным контуром отопления не может work normally and in the event that the coolant is drained in order to avoid affecting the device by the force of steam. This is explained by the fact that the coil will continue to heat up, despite the fact that it will be deprived of coolant. Under the influence of high temperatures, the steel hull will burn.
Many wonder what is more profitable -stove with a water circuit or autonomous heating system. The fireplace will be cheaper, even if you mess with the installation of a shirt. Such equipment can be connected to any heating system, and any part can be replaced if any node fails.
Any kind of device can be used with such a device.fuel. The equipment is not only functional, but also allows you to decorate the room. The described devices are universal. They fit into any style direction of the interior.
To tile the furnace with a water contour for privateHome can be one of the many materials. Automation in such structures is absent. This not only simplifies the system, making it more durable, but also forces some users to abandon such devices in favor of other solutions. After all, the latter can be ignited by pressing a button.
