How to make a bath a furnace correctly

Do.It.Yourself furniture furnace furnace (60 photos): drawings of a metal stove, diagram and size of an iron structure

Taking a particular project, it is important to remember that the main thing is your own security. That is why to stoves for the garage. From metal, gas cylinder, and in general from any material. There are very specific requirements, the ignoring of which entails no less specific threat to your life

  • When arranging a chimney, take care of the tightness of its channel;
  • Place the oven at a solid distance from flammable objects and liquids;
  • Do not use suspicious substances as fuel, since pairs secreted during burning can harm your health;
  • The exhaust valve should be no less than 10 cm in diameter;
  • Recommended dimensions for standard bourgeois. 70x50x35 cm, while the volume of the structure should not exceed 12 liters.

Choosing material for the construction of a furnace

Currently, there are many available stove construction schemes, but it is recommended to choose the simplest drawing to a beginner master.

What brick should the stove be from? It is not easy to choose the right building material. With minor financial capabilities, you can choose a red brick of dubious quality.

However, the dimensions of such a material rarely comply with accepted standards, for this reason wide seams can turn out. Up to 11 mm, which is absolutely unacceptable when erecting the furnace.

Often a bath stove is erected from chamotis brick, which consists of 75 % frying clay. Such material is resistant to overheating and high humidity, cracking and deformation. In terms of technical and operational characteristics, chamotis brick exceeds all existing analogues, but the price is much higher.

A furnace is being built from chamotis brick, and it is better to equip a chimney from refractory red bricks.

For construction work, you will need clay, which can be obtained independently or purchased at a specialized point in conjunction with bricks.

To fold the brick stove, you need to prepare the following materials:

  • Shag;
  • Heat.Resistant brick;
  • Clay and sand of large granularity;
  • Grate, door for blown and the furnace part, cleaning wells, cast.Iron plate and grate;
  • Asbestos cord; ;
  • Zinc wire;
  • Corner;
  • Ruberoid.

These materials are enough to build a simple brick furnace with your own hand.

Materials for creating a brick furnace in a bathhouse

A set for independent construction of a brick bathhouse implies the presence of materials:

  • Ceramic brick blocks;
  • Clay fireproof;
  • Quartz sand;
  • Waterproofing material;
  • Asboshnur;
  • Steel wire;
  • Brick (fire.Resistant);
  • Oven accessories (doors (blown), gate valves and grates).

For work, tools are used:

  • Level, coal ruler, plumb line (cord with cargo);
  • Small hammer and rubber kiyanka;
  • Master OK;
  • Corner grinder complete with an abrasive circle;
  • Container (trough) to knead the solution.

Carefully approach the choice of brick for masonry. Its strength should be above the strength of ordinary red and white brick.

Therefore, chamotum brick, which has the highest refractory properties, is the best option. However, its price is much higher than on analogues.

To minimize the costs of building a furnace, expensive chamotis brick is bought in a limited amount, only for the formation of those areas that are subjected to the strongest heating.

What is the difference: for brick or under metal

Metal stove is much stronger than brick. Installation with a slight distortion, deformation of the base will not bring much damage to the metal furnace, while for the brick, such foundation movements mean a complete failure. Hence the need for increased strength for a brick furnace. Metal stoves are usually quite easy, which allows you to do without a separate foundation. The foundation for an iron stove in a bathhouse is not required. For them, it is necessary to provide proper fire protection measures. An asbestos canvas, a sheet of roofing under a metal furnace protruding outside the furnace at least 25 cm, and before the firebox. At least 40 cm.

The brick furnace, possessing much greater mass, does not tolerate deformations of the base and needs a full.Fledged foundation, arranged with the expectation of large pressure of the furnace and compensation for shrinkage processes. There should be no connection with the general foundation, otherwise the difference in the pressure created on the base can lead to destruction.

Materials and tools

In order to build a brick furnace, you will need:

  • Red and refractory brick;
  • Clay;
  • Sand;
  • Blunt door;
  • Furnace door;
  • Grates;
  • Feeding doors;
  • Asbestos.Cement plate;
  • Stones.

When choosing a refractory material, preference is given to a standard brick

Since the brick furnace requires a strong base, it is necessary to fill in the reinforced concrete foundation. To do this, additionally prepare cement and crushed stone, as well as a metal mesh or reinforcing rods.

A bath oven can be folded both from brick and stone, using pieces weighing from 1 to 5 kg. Butt, granite or smoothness is suitable for these purposes, but you should not use flint. When heated, it cracks to pieces.

In your work you will need traditional tools of a stove.Stove or mason:

  • Trowel;
  • Hammer;
  • Bubble or laser level;
  • Patching cord;
  • Plumb line;
  • Construction square 40×40 cm
  • Trombovka;
  • Plaster rule;
  • Containers for solution and bulk materials.

To trim brick, you can use a corner grinding grinder with a stone around. This will allow masonry more carefully than when working with a hammer-brown.

If your choice is a metal stove, then prepare:

  • Sheet steel 1 and 5 mm thick (it is better to use heat.Resistant varieties);
  • Grate;
  • Metal corner with a shelf 40-50 mm.

Doors can be made from the same metal or use purchased by hung on loops and jokhokolds. As a chimney, you can take a steel pipe with a diameter of at least 100 mm. Its length should be at least 4 m. This will ensure good traction. By the way, a metal chimney can also be used for a stone furnace.

A beautiful cast.Iron door will make the stove more attractive

As for the tools, it will be needed to build a metal heel:

  • Welding transformer or inverter;
  • Angle grinder;
  • Cleaning and cutting circle for metal;
  • Electric drill with a set of Sovers;
  • Roulette;
  • Scriber.

If the design of the bath furnace includes a tank for heating water, then you should additionally take care of the pipe of the large diameter, thread and taps, which may be needed to arrange a hot water supply system.

DIY Bath stoves from metal

For such a stove, the foundation is optional. But something needs to be prepared. A metal sheet is laid in place of the furnace and fix it to the floor. On top of it. A sheet of flat slate. Both the lower sheet and the slate should protrude for the dimensions of the future furnace by 5 cm.

Develop a drawing of the furnace. She should have a furnace, blown, a door for a heifer, a valve. May also need accessories. It is better to take the steel accessories, since it can be welded into the future oven.

If the pipe is iron from pipe rolling, then the valve is more convenient to place in the upper part of the furnace, and not in the pipe.

What is the iron stove made in the bathhouse made? It can be made of any material with your own hands. But it will be better to make an oven of 20k steel, which is used for the manufacture of boilers. Or from steel 20×13, for the manufacture of furnaces and heat exchangers. The last steel is quite expensive. Sheets should have a thickness of at least 5 mm.

Buying stoves made of cast iron have advantages. Cast iron does not burn longer. The boiler steel burns out significantly longer than the usual.

The furnace has the same constructive elements as a brick furnace. At first there are a firebox with a blower opening, then a heater. Put a valve on top and make a transition to the pipe. It is better to make a larger stove. Smoke circuits in the iron furnace are not done. Instead, you can put a convection casing around the furnace. This will increase the power of heat transfer.

Convection casing. Part of the furnace that performs the function of the heat exchanger. Takes cold air from below, quickly heats it and releases it from above.

Made of metal, usually from galvanized tin. The casing should not have contact with a hot stove, and it should be at a distance from it no less than 10 cm. Where contact is inevitable. An asbestos cord is laid. It is also necessary to observe the distance from the casing to the combustible parts of at least 25 cm.

The height of the casing is at least 2 meters, if necessary, you can capture part of the chimney pipe into the casing. At the bottom of the casing, holes are made, at least 1 hole with a diameter of 2 cm for each cubic meter of the air volume in the steam room. In the upper part of the casing. The same number of holes for the output of hot air.

Holes can be made more or less. The main thing is that the air fence is carried out evenly around the entire perimeter of the casing. Such a device will increase the heat capacity of the furnace and accelerate the steam room by about 20%.

Bath stoves with water tank

A person who is capable of brewing a stove is able to make a water tank. I’ll tell you how to make his work more effective.

make, bath, furnace

Rodger tank can quickly warm from the air in the steam room. The air temperature in it is 50–90 degrees, the water in a not too large tank will be a temperature of 40-60 degrees. So that heating occurs faster, the tank should be made by a elongated narrow shape and place higher. A tank of any structure should have a free cover. Without this, he turns into a boiler, to which completely different requirements for welding and safety.

The second option is a hot water box built into the oven. The box should in no case have a direct contact with the flame from the furnace. It must be put in one wall in a stove, so that between the firebox and the box is at least 20 cm of stones. However, at the same time, the water temperature in the box can become too large, and it can be burned. After all, the built.In box is usually not too large. With an intense furnace, the water in it can even boil.

To warm up a large amount of water, it is better to use a separate tank. If its dimensions are too large, you can use a furnace for a bathhouse with a heat exchanger.

The heat exchanger is a metal rod with a diameter of 10 to 20 mm, at one end in the furnace, and the other ending in the tank with water. It can be welded tightly in the furnace and in the tank. And make a ring or spiral out of it in the tank. Heating will be faster.

At the exit from the stove, the rods must be in the pipe, between it and the pipe should be at the entrance and output of the asbestos ring, the pipe should not have direct contact with the walls of the furnace and contact with combustible objects. The rod should not have contact with the flame in the furnace. It should be in the stones of the heater.

When heated, heat will be transmitted through the rod to the tank. Water will heat up much more efficiently than from the air of the steam room. The intensity of its heating will be limited by the “bandwidth” of the twig-exchanger rod, and the water will not boil and will not be too hot.

Some make a furnace for a bath with a water circuit for warming water in the tank. This is not quite the right option. For a water circuit, constant filling with water is necessary. This is not always convenient to heat the stove and check each time if there is water in the circuit. Even if you make pipes made of heat.Resistant steel, plumbing elements. Ball valves, gaskets may be unusable when heated.

Theoretically, water in the tank can boil, not every valve or gasket can withstand this temperature. If you mount a water circuit without a tap. You will not be able to control its filling with water, because only with the help of the tap you lower the air from the contour. Therefore, it is better to use a rod heat exchanger. It is much safer.

Bath in the city

Many people wonder how to choose a bath for a bathhouse in a city apartment, or if you can not make fire? Under such conditions, electric burst for the bath will help. You can also make it yourself. The main thing is that the power of the power grid allow and there is a necessary qualification of an electrician.

Materials

As for the necessary materials, this is:

  • Any pipe made of suitable material, the diameter of which is half a meter. The length should be a wound of one and a half meters. She should have entire walls. The presence of one hole is permissible. It can be arranged as a hole for the furnace;
  • The coupling along with the sheets of metal;
  • Capacitive container and valve.

From the tools, a hacksaw for cutting metal surfaces and a device for welding work will come in handy.

Brick bath stove diagram

From the above, it was already flowing that there were several principal schemes of the brick furnace:

However, each allows many options for implementation. In other words, the above schemes clearly demonstrate characteristic, but do not exhaust the possible.

Bath furnace device: direct flow

Typically, in the brick furnace of the implementation of the direct.Flow structure, a closed running stove is accompanied. In this case, there is no reason to fear that the furnace gases will not have time to cool before leaving. Passing them through a mass of stone laying quite effectively selects heat.

By the way, the diagram shows that two types of bricks are used in the design of the bathhouse: red fireproof and chamotis. They are shown in red and yellow. Pay attention to the fact that the gap remains between them. This is a significant moment.

Installing A Toe Kick Ducting Kit. Toe Ductor

The advantage of direct.Flowing can be considered its simplicity, including the simplicity of maintenance. The stones, of course, are unlikely to be laid perfectly the first time, but over time you will find the optimal amount and location.

Designs of bath furnaces with smoke circulation

You already know the purpose of the smoke circulation, but the difficulties associated with it is not yet. In the furnace, everything is built on compromises. And this system is no exception. To begin with, the horizontal channels are much better than vertical both in the issue of heat distribution and the durability of the furnace. There is no much difference in temperature in vertical, the stove does not crack. But with this location there is another problem: overgrowing the walls of soot. Vertical overgrown more slowly, but here you need to clean once a week, otherwise the thrust decreases and the efficiency falls. Therefore, vertical channels were preferable.

The number of revolutions can vary from 1 to 12, but practice has shown that the optimal number of revolutions does not exceed 4. As for their cross.Section, it should not be too small and too big. In the first case, there are more hooks for soot, in the second. Inefficient heat fence.

On a note! The channels from the inside should be as smooth as possible, they are specially cleaned for this from the residues of the solution. When laying, the most flat geometry should be facing inward. Reason. Any roughness is a clue for soot.

Bath furnace device: cap

The design of the bath for a bath may not contain channels. We have already shown you the device of the simplest captacco stove. Now a little more.

Its principle is simple: you need to build something like an inverted glass above the firebox, and make an exit to the chimney next to its lower edge. This is a fairly clean design that suffers little from soot. Gases move as they want. Heated rise to the bottom of the glass, passing it warmly, while they cool and strive down, new portions from the furnace are replaced by them to replace them.

  • The upper part of the furnace warms up well, and for good heating, the steam room needs to be warm from below. This is treated by a system of two caps.
  • For the right firebox, you need a skill. In the overheated stove, the gases stop going under the cap, it is easier for them to immediately slip into the pipe. It is treated with a fine adjustment of the air entering the furnace.

With a tank or a coil

In an article dedicated to a brick stove with a closed heater, we talked about how to properly place a water tank in a furnace device in the bath so that the water did not heat up too early, did not boil, increasing humidity with heavy steam, and it was convenient to use the tank in conditions of manual filling.

Here we simply note that the coil inside the stove seems to us more optimal than the adjacent tank with water. It will be enough to follow the angles of the pipe inclination and water in the system will run only due to gravity and thermal convection.

In addition to the serpentine, a register of any other form can be put into the brick oven. The location may be the firebox, and the heater, and even the stove pipe.

6 SHARKBITE Mistakes NOT To Make! | GOT2LEARN

Step-by-step instructions for creating a heater

Calorifier stove is one of the simplest metal furnace structures. It consists of a tank for water, furnace and chimney. Perhaps this is the simplest design that can be made independently.

A drain tap, a firebox and a stove, and a pipe on an extract of smoke are attached to the water tank. Therefore, at first, from sheet steel 8-10mm thick, it is necessary to make the frame of the stove and firebox, and then make a stove and chimney.

  • First of all, from the corners and pieces of sheet metal, we make the base of the firebox frame using welding. It is necessary to lay a ball brick inside the stove, this is important. Next, a stove is made, where the stones will be located.
  • Then you can already proceed to the manufacture of the chimney. The chimney hole is installed directly above the stove. Well, in the end, it is necessary to start the manufacture and installation of a water tank.
  • As a rule, in such models of stoves, the water tank is installed on the back of the stove. There must be a drain crane in the lower part of the tank for draining water. After the manufacture of the finished design, it must be checked for the presence of smoke in the room, and the presence of traction.

Another popular option for making a bathhouse is a brick oven. However, it should be understood that the cost of such a furnace will be very high if you use the services of qualified stoves.

But you can, of course, make your own stove yourself for your own brick bath. Only in this case you will have to spend a lot of effort and time, but at the same time, you can save a decent amount of money. Although, if you carefully examine and read a lot of literature on such a topic, then you can make such a stove well.

  • Therefore, if you still decide to make a bath for a bath with your own hands, you can follow the pictures below with a detailed description. But remember, this process is long and painstaking, and in some places it will have to have great patience and endurance to achieve the desired result.
  • Of course, at certain stages of the construction of the furnace, any incomprehensible nuances or difficulties may occur. In this case, our colorful and illustrated photos will help you, where all the main stages of construction will be shown step by step.
  • It is also necessary to remember that you need to make a stove carefully and slowly, so that there are no mistakes. Otherwise, your “jambs” or miscalculations will then be difficult to fix, if it is generally possible.

Thus, you can make a bath for a bath with your own hands, but the question is how well it will be done.
