Many people are increasingly thinking about switching to autonomous heating. In this case, the entire system will cost a large amount. A good alternative is a homemade gas boiler. At first glance, this task may seem impossible. But if you figure it out, it is within the power of people who have experience in installing, repairing and operating gas equipment. Only such professionals can afford to do exactly what the owner needs, as well as significantly reduce the cost of purchasing equipment.
What do you need?
There are a lot of instructions on how to make a boiler for heating on different types of fuel: solid, liquid, electricity and others. But not many people decide to build such a structure on gas. Basically, the problem is that the installation will need to be connected only after agreement with the relevant authorities. But first things first.
So, for starters, you need to understand that you can use such a heating unit only at your own peril and risk, the responsibility for the consequences, which can be deplorable, falls entirely on the shoulders of the homeowner.
After realizing this, you need to find suitable drawings. It is desirable that they describe in detail about heating boilers, connection, cooling, chimney, deflector and other important points. The master must understand such documentation in full, because even one change will adversely affect the operation in the future. It is desirable to see a few photos of finished systems. This will help to «assemble the unit in your head.»
After that, you need to calculate the amount of all materials for the heating boiler. It must be understood that in no case should the indicated metal be replaced with another to reduce the cost of construction, because it may turn out to be soft, which will quickly render the installation unusable. Then purchase blanks, as well as already assembled individual components (buttons, deflector, taps, etc.).
It is also important to have your own tool, which is needed for joining metal sheets, cutting and grinding them. It is also necessary to have a soldering iron, a set of screwdrivers and wrenches, hammers and all kinds of other tools that allow you to work with metal and electrical circuits.
What to do?
When all the necessary components for the process are assembled, you can take the first steps to create heating with your own hands. So, according to the drawings, sheets are cut out, tubes, corners, internal parts are prepared. It should be noted that some components do not have to be created independently. So, for example, a deflector, which will be easier to buy and put on the end of the chimney.
After that, you can start assembling according to the drawings. Under no circumstances should you rush. It is important to understand that improperly placed components can simply lead to the inoperability of the device. It is even advisable to watch a video where the main points will be told.
After everything is connected into a single system, you need to clean the edges well and paint the unit. This is necessary, since during operation in cold weather condensation will appear, and the metal that is not covered on top will simply begin to rust.
It must be said right away that there are a number of requirements for a gas boiler. So, for example, it is necessary to have a special exhaust gas outlet, on which there will be a deflector on top. In addition, everything must be perfectly connected. In other words, it is forbidden at the legislative level to use heating systems operating on this type of fuel without the necessary checks and obtaining the appropriate documentation. Therefore, before installing a do-it-yourself gas boiler, you must definitely call a specialist who deals with the above.
The fact is that such equipment belongs to devices that have an increased danger. And for a self-made boiler, it is imperative to obtain permission for installation in the gas service. And she, in turn, needs to provide a certificate for the product, moreover, the original, not a copy or photo.
You need to understand that getting such paper is not easy, and most often it costs a large amount of money. In addition, the minimum deviation from all prescribed norms leads to a complete ban on the use of home-made installations. This is a strong argument in favor of the fact that the manufacture of a gas boiler with one’s own hands can only be done by a person who has extensive experience in the installation and maintenance of such units. This refers to the assembly and assembly of the system from separate units, each of which is manufactured in compliance with GOST, and the use of hand-made parts is minimized and is permissible only in non-critical areas.
When all the points with the relevant services are settled, the boiler can be installed. Unfortunately, there are rare cases when homeowners manage to do this without the consent of the technical supervision authorities, which is a gross violation of the law and is fraught with unpredictable consequences.
Calculations for a homemade gas heating boiler
Do-it-yourself gas boilers need to be done, only by accurately calculating everything. If this is done correctly, the equipment will save the owner not only one-time costs, but also operating costs.
It is necessary to manufacture the unit, taking into account the heat loss in each room where heating will be carried out. You need to understand that even if the rooms are the same, the heat transfer in each will be different. It is best to carry out calculations with a small margin. In this case, the layout of the room will not work, it is better to build on the actual size. It is important to check everything several times in order to accurately eliminate the possibility of an error, because it can lead to excessive fuel consumption and increased costs in the future.
In order for do-it-yourself gas boilers to work as expected, you need:
- calculate the entire hydraulic system;
- take into account the costs of the chimney, including the deflector;
- determine in advance the diameter of the pipes;
- set the desired pump power;
- and calculate the resistance of the system.
If everything is calculated correctly, there should not be any failures.
Many people think about how to create autonomous heating with their own hands. This is mainly due to the price of boilers. There are many drawings that indicate how to do everything yourself. But in the case of gas equipment, you need to remember that all of it must undergo mandatory certification.
