- Boilers with a power of 70 to 100 kW, made of high-tech steel 3 mm thick. The area of the heated room is designed to be up to 500 square meters. meters.
Premium series boilers are non-volatile and operate on natural gas with natural or forced coolant circulation. The boiler heat exchanger is treated with a special anti-corrosion compound, which allows you to extend the life of the boiler.
The boilers are equipped with protection against overheating, soot formation, and draft blowing.
Universal connection on the right and left sides allows you to install boilers in any room.
Convenient system control and setting the required temperature make the Premium series boilers one of the most popular among Lemax products. Boilers are produced as single-circuit, intended for heating a room, and double-circuit, which in addition to heating the room supply hot water.
Let's take a closer look at the most popular of the models described above.
The heating gas boiler "VEGA" is a harmonious combination of efficiency and high efficiency of fuel combustion, which reaches 92%. This wall-mounted equipment has a hot water supply function and is equipped with a modern boiler. Equipped with powerful atmospheric burners made of stainless steel, this model easily copes with the functions assigned to it. The special rectangular shape of the turbulators and heat exchanger takes the operation of VEGA gas heating boilers to a new level of efficiency.
MIMAX engineers took care of the convenience of boiler control, equipping all models with Italian automatic SIT systems, recognized throughout the world as one of the best in their price segment. The boiler heat exchanger is made from first-class cold-rolled 3-mm metal, the thermal insulation properties of which are enhanced by special materials. Due to this, heat loss is reduced to a minimum.
The design of the VEGA boiler is optimal for Russian conditions. Moreover, the anti-corrosion protection of the structure ensures that the equipment will last for many years without a hint of breakage or wear.
The floor-standing gas boiler "MIMAX" type KSG or KSGV also deserves attention, because it boasts compactness, high performance and efficiency. The KSGV model is equipped with a 12-meter hot water supply circuit coil, which increases the efficiency of the water intake circuit compared to domestic or foreign analogues. In addition, the design of the MIMAX KSG or KSGV floor-standing gas boiler uses asbestos-free materials, which contribute to effective heat conservation.
The power of different configurations varies from 7 to 40 kW, and the heating area can be either relatively small (70 square meters) or significant (up to 400 square meters).
Models KSTG and KSTGV can safely be considered the pride of the company, because they are distinguished by a long service life and excellent build quality using high-tech European equipment. Each piece of equipment undergoes multiple quality control, which reduces the likelihood of defects to almost zero.
"MIMAX" - boilers that can safely be called one of the most profitable offers on the market. And this statement is completely justified, because the KSTG and KSTGV models are standard gas burner equipment of the European class. It is versatile because it operates on different types of fuel.
Today, the buyer has the opportunity to purchase a MIMAX boiler, the technical characteristics of which will fully meet the client’s needs. In particular, the KSTG and KSTGV models can have a power from 12.5 to 40 kW, and the maximum heating area can vary from 125 to 400 square meters. Depending on the choice of one or another variation, gas consumption ranges from 1.59 to 4.77 cubic meters per hour. At the same time, the efficiency of devices such as KSTG and KSTGV ranges from 76 to 87%.
And as a result
It is obvious that MIMAX gas boilers are deservedly in great demand in the domestic market. Their decent performance characteristics, as well as their low cost relative to similar models of Russian and foreign production, make them very popular. Today, in the eyes of a potential buyer, the MIMAX brand looks like a 100% guarantee of long service life and high quality. And all this can be obtained for relatively little money. Naturally, such a unique product will never be ignored by the market.

ABC of using a device with automatic equipment AGU-T-M
Setting up Mimax is easy, using it is not difficult.
- Pull back the flap.
- Press the gas valve button and light the wick. In this case, the bimetallic plate heats up.
- Wait for the lever to move to the desired position for a few seconds, holding the button, then release it.
- Program the desired temperature using the control knob.
- Other types of boilers require ignition and have a knob with a scale to regulate the temperature.
A special nozzle made of steel, which is resistant to chemical, thermal effects and corrosion, allows for stable combustion and barely audible operation.
Leader Series

- The boiler is equipped with piezo ignition, which allows you to conveniently light the boiler. The thermomanometer displayed on the panel allows you to control the temperature and pressure of the gas.
The most expensive models of Lemax boilers. The manufacturer promises a boiler service life of up to 25 years.
Possible faults
No matter how hard the engineers try to prevent possible problems, no matter how attentive the owners themselves are, sooner or later everyone faces failures. If Lemax Premium, for example, goes out (the main burner stops arbitrarily), we can assume the following reasons:
- weak vacuum in the smoke passage;
- gas outlet overflow;
- Incorrect thermostat setting.
First, inspect the channel through which the smoke is removed. If any dirt or blockages are found, they are removed immediately. If this does not help or nothing interfering is detected, you need to configure the regulator.
If a gas leak is detected, you should give up the idea of fixing it yourself. All restoration work may only be carried out by authorized gas service specialists.
Please note: cleaning chimneys and burners can help with excessively elongated flames that take on an orange or even red hue.
If there is no movement of water in the system, it needs to be topped up. When this measure does not help, you will have to redo the entire heating circuit. If the boiler suddenly turns off due to a temporary failure in the gas supply, the inlet valve must be closed. Then very unpleasant consequences will be excluded. If you cannot light the boiler, the problem may be related to the igniter or thermocouple. It is necessary to clean the contacts and replace the thermocouple. You also sometimes need to work on the traction sensor, connecting it not “by crimping”, but according to a more practical scheme.
Important: ignition is strictly prohibited if the fire from the igniter rushes outward, which is almost always due to a lack of draft and poses a great danger. .
PRIME series
PRIME series – wall-mounted gas boilers with a power from 18 to 32 kW. Convenient operation and installation of Lemax boilers of this series makes them popular among users. The boilers are equipped with a brass hydraulic hammer, which does not allow the system to fail when the water supply pressure changes.
The closed combustion chamber allows you to use a boiler in a private house or apartment, removing combustion products through a coaxial chimney.
- The boilers are double-circuit, which allows not only to heat a room of up to 300 square meters. meters, but also use hot water.
- Boilers depend on electricity, which is not always convenient when the power goes out frequently. To ensure uninterrupted operation of the boilers, a generator is installed in this case.

What are the installation requirements?
Standard requirements have been established for the installation of a Lemax double-circuit gas boiler. It is necessary to comply with the usual provisions for heating units, the presence of connection points to the water supply, gas mains, and the presence of a chimney.
Important. Installation should be carried out by qualified specialists who have experience working with gas equipment; amateur activities are not allowed here.
A prerequisite is the installation of all components and parts provided by the manufacturer (and specified in the manual): expansion tank, shut-off valves, flaps, and sensors. The base for the equipment must be stable and solid, preventing subsidence and distortions of the boiler, especially its displacement. When choosing the installation location, you should take into account the possibility of servicing the unit and its parts, so that, if necessary, it is convenient to dismantle the burner block or sectional heat exchanger.
Regarding the chimney, there are several options: solid, brick, or assembled from separate sections of the pipe. The latter option is very popular (and recommended by companies specializing in the production of gas exhaust systems), and it is also easy and quick to install.
