For heating residential and non-residential premises, medium and large areas Floor-standing gas boilers are most often used. They are among a huge range of heating equipment, which also includes solid fuel, diesel and electric boilers, have a low cost of ownership. It consists of the relatively low price of floor-standing gas heating boilers themselves, inexpensive service and fuel efficiency, i.e. gas

It is often difficult for a buyer to figure out on his own what kind of domestic boiler he should buy. Self review equipment market, reviews of other consumers, advice from professionals will certainly lead him to the conclusion that he needs to buy products domestic manufacturer– floor-standing gas boilers “Lemax”.

Where to buy Lemax floor-standing boilers

We invite you to buy Lemax floor-standing gas boilers directly from the factory or by contacting a dealer in your region.

Floor steel gas boiler Mimax CSG produced in Taganrog is widely used in our country due to its simplicity of design, efficiency and low price. Thanks to a wide range of powers from 7 to 40 kW, this type of boiler is capable of heating a private house or other premises with a total area of ​​30 to 400 square meters.

In addition, Mimax gas boilers have good reviews due to their compact dimensions, quite nice appearance and high efficiency. They can operate both on natural gas and, when replacing (injectors), on liquefied gas.

Model range and description of gas boilers KSG "Mimax"

Boilers from the Taganrog manufacturer differ in their intended use:

- single-circuit

- double-circuit

Single-circuit floor-standing gas Mimax boilers are intended for heating only. They have one circuit; on the back of the device there are fittings for connecting the coolant (direct and return), with a diameter of 40 or 50 mm. These boilers are marked KSG.

Mimax floor-standing gas boilers

Depending on the power, they can be designated as follows: KSG-7, KSG-10, KSG-12.5, KSG-16, KSG-20, KSG-25, KSG-31.5, KSG-40. What do these letters and numbers mean?

KSG is a Steel Gas Boiler, the numbers behind these letters convey to us information about the power of this heating apparatus. The boilers are also different technical characteristics. For example, the abbreviation KSG-10 indicates that this boiler is single-circuit, with a power of 10 kW, and a heating area of ​​up to 90 square meters.

Double-circuit floor-standing gas Mimax boilers can be used for both heating and hot water supply. They, accordingly, already have two circuits. The second circuit for hot water supply is heated by the main heat exchanger, where the coolant itself is heated. The water in the circuits does not mix.

According to the instructions, Mimax double-circuit boilers have a slightly different designation, namely KSGV. The decoding indicates that this is a steel gas hot water boiler (hot water). In stores you can find the following options: KSGV-12.5, KSGV-16, KSGV-20, KSGV-25, KSGV-31.5 and KSGV-40.

The connections for connecting the circuit are also located on the rear side and have a diameter of 1/2 inch. Minimum power Mimax double-circuit boilers are 12.5 kW, in contrast to single-circuit boilers, for which this parameter is 7 kW.

Double-circuit boilers, like single-circuit boilers, have a special thermometer on the front side that shows the temperature value on a scale from 0 to 120 degrees Celsius.

Construction of the KSG Mimax boiler


How to choose a floor-standing gas boiler

KSG Mimax boilers for heating are selected according to the area of ​​the house and are divided according to thermal power. Models from 7 to 40 kW are available on the Russian market. Do not forget about the rule of 1 kW per 10 sq.m., which we also apply to.

For example, if you need to heat a private house with an area of ​​100 square meters. meters, then you need to buy a KSG-12.5 or KSG-16 boiler, if with a reserve, etc.

When choosing a double-circuit floor-standing boiler, you need to take into account that in order to obtain a normal amount of hot running water, you need to buy a boiler with a capacity of at least 20 kW. Such a gas boiler will produce approximately 7 liters of water per minute, at a temperature of about 35 degrees.

This is a disadvantage of most floor-standing double-circuit boilers, because for heating small house, for example, 50 square meters, a KSG-7 boiler is quite enough.

Using a 20 kW thermal apparatus, in in this case, turns out to be somewhat irrational due to the higher consumption of natural or bottled gas. Or you need to purchase a wall-mounted one with good performance hot water.

Automation for gas heating boilers KSG

KSG floor-standing boilers are available in two types gas burners:

— gas burner device AGU-T-M

— gas burner device AGU-T-E-I(R) type Euro SIT

KSG boiler with automatic control AGU-T-M

AGU-T-M device consists of the following main elements:

- gas valve with start button
— block tap with adjustment knob
— gas distributor
— thermal cylinder
- temperature sensor

How to properly use automatic equipment like AGU-T-M

1. Before lighting the igniter, move the damper.

2. Press the gas valve button and light the igniter. At this time, the bimetallic plate is heated.

3. Without releasing the button, wait a few seconds until the lever moves to the “on the button” position.

Device AGU-T-E-I(R) type Euro SIT

This type of boiler automation involves ignition, either from a match or lighter, or from a special piezoelectric element. To adjust the temperature of the coolant in the boiler, there is a handle with a scale. When starting the boiler, simply move the handle to the desired position and press the piezo button.

KSG boiler with Euro SIT automation


Automation with piezo ignition is completely energy independent, as well as simple automation type AGU-T-M.

Possible malfunctions in the operation of KSG Mimax gas boilers:

Description

Boilers KSG, KSGV are designed for heat supply residential buildings with a total area of ​​up to 250 m2 with a ceiling height of 2.7 m and hot water supply in the presence of a water heater. Powered by natural gas low pressure in automatic mode based on coolant temperature.

When using domestic gas heating boilers of the KSG model in heating systems, the following is achieved:

  • energy saving (gas consumption is reduced by up to 30%) due to the built-in gas pressure stabilizer;
  • reducing the amount of harmful emissions into the atmosphere;
  • increasing control accuracy temperature regime in room.

Domestic gas boilers KSG, KSGV have 3 degrees of protection in emergency situations:

  • when the flame on the pilot burner goes out;
  • in the absence of traction;
  • when gas supply stops.

Domestic gas boilers KSG, having the letter (B) in the designation, are double-circuit heating boilers, i.e. have a built-in water heater providing hot water supply. Double-circuit heating boilers KSGV, and single-circuit boilers KSG heating systems are produced in the design of gas floor heating boilers.

These KSG floor standing gas boilers are supplied with a highly efficient steel heat exchanger. For the most optimal removal of gas combustion energy by a convective heating surface, the method of extensive high-speed heat removal is used with a smaller volume of coolant in the boiler, thereby achieving high efficiency.

A gas pressure stabilizer built into the gas block of a domestic boiler ensures uniform combustion gas-air mixture on the main burners with constant heating output, regardless of the gas pressure in the network. Main gas burners made of heat-resistant of stainless steel with slotted grooves are placed evenly under the heat exchanger, creating a uniform thermal field in the combustion volume, which eliminates the formation of local overheating zones of the heat exchanger and its destruction.

The draft interrupter (draft stabilizer) equalizes the air pressure in the suction zone into the ejector of the main gas burners and near the exit of the gas-air mixture from the slotted grooves when the location in the firebox is open without adjustment, and also prevents the pilot burner from blowing out during a short-term overturning of the draft. energy independence

Detailed description

The parapet gas boiler KSG/KSGV “LUCH” is a modern heating equipment with compact dimensions and a closed combustion chamber. The air involved in the combustion process enters and is removed through one coaxial type chimney. The air flows in such a chimney are divided: the outer one works to supply fresh air, the internal one removes exhaust gases.

The small dimensions of the equipment allow it to be installed even in cramped rooms with small area. A gas boiler with a closed combustion chamber “LUCH” can be connected to communications on the left or right side. Pipes for connecting gas, heating and water supply pipes are located both on the left and on right side. Those pipes that are not in use are closed with plugs.

Isolated combustion chamber

A boiler with a closed combustion chamber is gas equipment for heating, in which the gas burner device is located in a compartment isolated relative to the room. Thus, the air from the interior of the room is not used during boiler operation. Special device coaxial chimney allows you to heat the incoming air, thus reducing heat loss.

The parapet gas boiler “LUCH” KSG/KSGV, thanks to the closed chamber and the coaxial type of chimney, can be installed on any wall. It does not require planning and organizing a traditional chimney; the terminal is displayed on any external wall in compliance with the distances from the window, ground and neighboring buildings specified in the passport. It is not allowed to lead the chimney into the entrance, onto the balcony or loggia. A boiler with a closed chamber does not require additional ventilation; it can even be installed in small room(for example, in the kitchen).

Tubular heat exchanger

Reducing the size of the heating system gas boiler"LUCH" did not affect its performance and efficiency. The efficiency of a parapet boiler is at least 92%. This was achieved, among other things, thanks to the special structure of the steel tubular heat exchanger. For the maximum possible heat removal, the heat exchanger is equipped with an optimal number of vertical tubes. The heat exchanger itself is made of durable, heat-resistant stainless steel 2mm thick. All these factors made it possible to significantly extend its service life.

Gas automation TGV307 (similar to EUROSIT630)

A reliable, time-tested automatic system - TGV307 (a complete analogue of the Italian EUROSIT630) controls the gas supply and is responsible for the safety of parapet gas boilers. Gas automatics TGV 307 are autonomous and do not require connection to the electrical network. Automatic TVG307, depending on the readings of the coolant temperature sensor, modulates the flame of the main burner, thus regulating the power.

Automation ensures the safe operation of gas heating equipment and produces an instant protective shutdown in the following cases:

  • Blockage, lack of traction;
  • Pressure drop below 600 mPa, gas supply stops;
  • Overheating of water (other coolant) in the system;
  • Flame extinguishment on the pilot burner.

The automatic gas burner device is located in the front part of the parapet gas boiler (as in models with an open combustion chamber). This simplifies its removal, maintenance and repair of heating equipment. The burner is made as a “pipe in pipe”. Before being supplied to the main outer tube of a larger diameter, the gas passes through the inner one. In the inner tube, preheating and preparation of gas for combustion occurs. This approach can significantly reduce fuel consumption and increase efficiency.

Purpose of heating boilers KSG/KSGV "LUCH" parapet

Parapet boilers "LUCH" can help solve the issue of heating and preparation warm water. Models marked KSG are equipped with one circuit and are intended for heating only. Equipment marked KSGV has two separate circuits - for heating and water treatment, so on their basis it is possible to organize reliable system heating and hot water supply for domestic needs.

One and double-circuit boilers with a closed combustion chamber "LUCH" are produced in the power range from 8-20 kW, which allows you to choose optimal solution for rooms ranging from 80 to 200 m².
