How to assemble a homemade long-burning boiler with your own hands and provide heating with firewood, video tips

February 26, 2020

Providing your home with warmth for the winter is a very important task. And if in the city its performance is undertaken by special services, then outside the city very often you have to do everything yourself, in particular, make and install heating units.

In this article we will talk about homemade long-burning boilers, working on firewood.

Of course, heating boiler, running on different fuels, can be purchased for sale. However, the same gas boiler will not be able to work everywhere, but a wood-fired boiler can burn a house regardless, how far it is located from the gas main.

Despite everything else, homemade boilers Prolonged burning compared to simple stoves have a longer period between loads of firewood, while the efficiency of space heating is not reduced. Besides everything, we offer you to watch a video on the topic of assembling long-burning boilers with your own hands.

The principle of operation of a long-burning boiler

The duration of burning a wood boiler depends on its design and processes, happening from within. The principle of operation of boilers is as follows: fuel is burned from top to bottom, and not vice versa, as in an ordinary wood-burning stove. In the furnace of a conventional boiler or furnace, the bottom layer first burns, after which hot streams rise and involve all layers in burning, firewood burns very quickly and must be added every few hours, otherwise the oven will cool down.

In boilers of long burning at first the top layer burns down, and then the fire goes lower and captures each subsequent layer of firewood. One bookmark of fuel allows it to smolder approximately for 30 hours, and after its complete combustion of ash and soot remains a minimum.

The adjustment mode allows firewood to smolder for a very long time - more than a day, and after their complete combustion of soot and ash remains a minimum.

But it's worth remembering, that long-burning boilers, made with their own hands, in living quarters it is better not to put, as they cannot guarantee your safety in use. It is best to equip them with such premises, as:

  • technical;
  • production;
  • greenhouses;
  • houses, under construction.
  • residential buildings until the installation of the main heating system.

Pros of homemade long-burning boiler

Though, that wood boilers, made with their own hands, can be installed not everywhere or used as a temporary solution in residential areas, many prefer them, because they are easy to operate and have a high return on heating.

Advantages of such boilers:

  • simple regulation of the process of active decay;
  • prolonged burning without the need to add firewood;
  • easy to assemble the structure with your own hands;
  • high efficiency;
  • maximum fuel combustion.

How to assemble a wood boiler with your own hands

In the regions of the country, where there is no natural gas, solid fuel is highly valued, on the basis of which heating boilers work. At the same time, almost every such region has special enterprises, which can provide solid fuel.

Long-burning boilers can work not only on firewood, but also on such types of solid fuels, as:

  • sawdust;
  • pellets;
  • peat;
  • coal.

Materials for making a boiler with your own hands

To assemble the boiler with your own hands, the material for the case is necessary. This may be appropriate:

  • large diameter metal pipes;
  • barrels;
  • round tanks;
  • gas cylinders and other containers.

Most often containers are steel and cast iron, let's consider, what is the difference in the characteristics of these two materials:

  • cast iron is resistant to corrosion, able to withstand high temperature loads, cools more slowly, than steel. At the same time it is fragile, difficult and expensive in terms of cost. Cast iron products are durable;
  • Legs' steel, it is cheaper and more durable. In addition, it heats up faster and easier to weld, therefore steel boilers are easier to repair. But along with this condensate, which occurs due to fuel combustion, eventually destroys the walls of the furnace. In industrial designs they are protected by ceramic lining, but it is impossible to do it with your own hands.

Steel boilers are more popular among users. If you want to assemble the boiler with your own hands, remember, what needs to be provided proper air supply with the ability to regulate the process of burning firewood. To achieve this, you need to do the following:

  • competently calculate the power of the structure;
  • choose quality materials;
  • pre-prepare a design drawing;
  • be able to make quality welds;
  • strictly adhere to the technology of installation of the structure.

And now let's consider the simplest designs of long-burning boilers, which you can collect with your own hands:

  • based on an iron pipe;
  • on the basis of a barrel;
  • potbelly stove;
  • Slobozhanka.

Construction based on metal pipe

design parameters should be as follows:

  • pipe diameter - up to 30 cm;
  • height -86 cm;
  • the slope of the pipe should be at least 0,1% to the horizontal plane;
  • chimney diameter - 10 cm;
  • the connection is welded.

At the bottom of the structure should be a door for adding firewood, and for blowing and cleaning of capacity from soot it is necessary to put grate.

Inside the structure must be placed pipe with a smaller diameter, connect to the pipeline, which goes around the room for the natural movement of the coolant. Then the system is filled with water, which can be heated for domestic use and used for heating. Install the dampers on the outside, which control the amount coming from the water tank.

Barrel construction of a copper

The work in this case looks like this:

  • cut the top rim of the barrel and align;
  • on the lid, capable of closing tightly, cut a hole with a diameter of 150 mm for carbon monoxide removal;
  • the chimney should be placed at a slight angle to the vertical surface;
  • the cover must be strong and fireproof. Make another hole in it 100 mm for oxygen access;
  • we put a pipe so, so that the gases can go vertically out;
  • the damper should not be placed too low, so that the fuel does not burn earlier, than required.

it is also possible slow down the process of settling firewood by cargo. Together with the mobile air distributor such design will provide burning of firewood during 60 hours.

Potbelly stove and its features

Almost everyone knows about this design. They consist of a water supply, which can provide heat to several radiators in the room up to 30 square meters. It can be used in such premises, as:

  • greenhouses;
  • country sites;
  • houses, under construction;
  • construction sites;
  • utility rooms.

How to assemble a boiler "Slobozhanka" with your own hands

The principle of operation of this design is quite simple. is two casings: one internal, and the second external, between them there is an air layer. Cold air comes from below, which is heated by the hot walls of the inner casing and rises, then exits through a hole in the outer casing.

To assemble such a unit with your own hands, prepare the following:

  • thick pipes;
  • sheets of metal;
  • fittings;
  • metal corners;
  • gas cylinders or pipe sections;
  • welding machine;
  • grinder;
  • drill;
  • hammer;
  • chisel;
  • electrodes.

The procedure will be as follows:

  • make an air supply device. To do this, we need a pipe with a length, which corresponds to the height of the furnace. Weld a bolt to it at the bottom, then cut from a metal circle a sheet with a diameter of a pipe or a little more. Drill a hole in it for the bolt, then connect to the duct with a nut;
  • take the Bulgarian and the disk on the metal, make slits vertically a centimeter wide. Air will get into the furnace through them;
  • cut a flat steel sheet with a diameter slightly smaller than the furnace. Inside makes a hole for the air duct, insert it with a blower down, then you need to weld, retreating from the end close 20 cm;
  • we do housing cylinder with airtight bottom. If a gas cylinder is taken for this purpose, the upper part is cut off, and if we make from sheet metal, then you need to weld the bottom;
  • to make a chimney, in the upper side of the housing make a hole for the gas outlet and weld a pipe with a diameter of about 10 cm;
  • install the air supply pipe, cutting a hole the size of the diameter of the air supply pipe in the center of the bottom of the combustion chamber. Then insert it, to be subjected to hanging down outside the housing;
  • do heat dissipating disc of sheet metal thick in 10 mm. It is necessary to cut a circle with a diameter slightly smaller than the case and to weld to it the handle from a steel wire or armature;
  • make a convection cover and attach it. The cylinder design should be a couple of inches larger than the furnace;
  • finally make a lid out of the remaining element of the gas cylinder or barrel lid. You can weld a handle to it.

Boilers of long burning, running on solid fuel, can be applied for various household needs. There is no better and more economical option for use on a country site or on a construction site. You do not have to refuel so often, as in traditional furnaces, you will also save on the purchase of a boiler.
