Russian-made gas boilers cannot be compared with well-known foreign brands, no matter how much we want the opposite. They are less efficient and only a few models have an efficiency higher than 90%. They have simple automation, which in most cases does not imply protection against overheating or freezing, against stopping the circulation pump. The heat exchanger is often made of the simplest short-lived steel alloys, much less often cast iron.
Nevertheless, there are significant advantages in the form of a 20-60% lower cost, ease of installation, availability of spare parts and a developed service structure. Some of the most successful domestic models have excellent, even by European standards, characteristics and have been serving without problems for more than 7 years.
Distinctive features of Russian gas boilers
The most important feature is the low cost of domestic boilers. It is achieved through the absence of customs duties, often lower transportation costs, cheaper labor, lower component costs, and lower technology research costs. Nevertheless, every year Russian models are becoming more efficient and functional, and prices in currency terms remain practically unchanged.
Adaptation to domestic conditions is also important: to low pressure of natural gas in the pipeline, voltage drops. Many Russian models, unlike rare foreign ones, are non-volatile, i.e. do not require connection to the mains, the automatics are powered by a heating thermocouple.
The device is based on the example of the domestic double-circuit model Conord KSts-g-30N: the minimum number of components, simple materials, uncomplicated non-volatile automation.
A simple design and principle of operation is the key to easy and quick troubleshooting. Finding a competent specialist is not a problem even in regions remote from the capital.
However, Russian gas boilers have a lower efficiency, on average by 4-6%, which means not only lower heating capacity, but also often higher gas consumption. Domestic models are less automated and less secure. Starting in most models is done manually, with the help of piezo ignition, as mentioned earlier, there are usually no additional protective functions.
Reviews of domestic gas boilers: advantages and disadvantages
Based on the technical characteristics, installation practice and owner reviews, you can visually weigh all the pros and cons of the boiler units:

Gas heating source
It is not advisable to make a gas version of a heating boiler for three reasons that are closely related to the features of its operation:
- Firstly, it is very difficult to comply with all the regulatory requirements of GOST, therefore, it is almost impossible to obtain a permit for operation from the inspectors of the gas service.
- Secondly, it is forbidden to install equipment of this class in rooms of certain categories (in particular, in the basement of a house). Thus, in private homes, its use is significantly limited.
- Thirdly, there is a high degree of explosion hazard during the operation of a gas boiler. handmade.
What types of gas boilers are produced in the Russian Federation
Boiler equipment manufactured in the Russian Federation is classified according to several criteria. This is an installation method, a method of gas removal, depending on electricity and the number of working circuits.
According to the installation method of the boiler unit, Russian gas boilers are divided into:
- Wall mounted. They differ in small overall and mass parameters, do not require a lot of space for installation and maintenance. They are mounted on the vertical surface of the room.
- Outdoor. They have larger dimensions and weight than wall-mounted counterparts. Installed on the floor of the room. A distinctive feature of floor structures is a wide range of power indicators. This makes it possible to use floor-standing boilers for heating buildings with a large area.
According to the method of exhaust gas discharge into the atmosphere, the products are divided into two groups - with an open combustion chamber or a closed one. The former use the air inside the building in the combustion process.
With a closed combustion chamber, the boiler is equipped with a two-channel chimney. An air mass is supplied through one channel with the help of a fan, and exhaust gases are discharged through the other. Depending on the design, gas heating boilers with one or two circuits are distinguished. The former are used to maintain the air temperature in the desired range.
The double-circuit model allows not only to heat the air mass, but also to prepare hot water for consumption. For this, a hot water tank of the required volume is connected to the boiler unit. Products used to heat homes or industrial premises are both dependent and independent of electricity. In the first case, to control the automation, you will need to connect the boiler to the power supply with the appropriate voltage indicator.
The control unit of the non-volatile boiler does not need to be connected to the network. This type of model is well suited for use in places where the power supply is intermittent. This will allow you to heat the room regardless of the presence of voltage in the network.
Solid fuel heating boilers
For one reason or another, all of the above types of boilers are not entirely suitable for making them with your own hands. There was only one option left - a solid fuel boiler unit. Firewood is used as fuel. Fuel burns quickly and, with high efficiency at the beginning of combustion, does not provide long-term energy production. But even here you can find a way out. Consider a couple of options for solid fuel boilers with a maximum percentage of its combustion.
Pyrolysis boilers or pellet-type boilers are great for domestic purposes, and they are easy to install at home.
Such options for do-it-yourself heating devices make it possible to simplify many operations for piping heating boilers and make it possible to equip them with an emergency shutdown system that is triggered when overheating.
Design features of digesters
Cooking kettle, universal cooking kettle, cooking kettle is a two or three-layer tank in vacuum or atmospheric design, vertical or horizontal type, made of food grade stainless or carbon steel, mounted on a rigid frame, or on adjustable supports with or without the function of tilting the brewing vessel, with a welded, removable or lifting cover, with a jacket for steam, water, oil, glycerin and can be equipped with low-speed and high-speed mixers of various types and configurations: frame type with fluoroplastic scrapers, scraper, paddle, anchor type, high-speed cutter type, squirrel wheel, etc. etc. Cooking kettles, cooking kettles, cooking kettles are equipped with automatic or programmed control panels using TOUCH-panels, which allow automating the processes of product preparation. There are four main types of product heating: 1-Steam heating. 2-Electric. 3-Gas. 4-Combined (Electricity + steam).
You can buy a digester according to pre-agreed options, dimensions and performance. Despite the demand for digesters, the price of a digester is always negotiable due to the unpredictability of costs.
