High-quality gas burner-type household equipment should be distinguished by safety, efficiency and ease of installation. Russian consumers can choose a Mimax boiler for wall or floor installation. The unit is suitable for rooms of any quadrature, can be equipped with an auxiliary circuit for domestic hot water.
Manufacturer Information
The Mimax company is located in Taganrog and has been operating since 2002. Initially, the brand produced gas burners of ASU with nozzles of the “Maxima” type, then began production of devices with automatic SIT security systems. After the gas burners went into serial production, the brand switched to the development of gas boiler designs.
The final product is focused on the Russian consumer. It took into account not the capabilities of electronic filling or wireless control, but efficiency. The equipment was supposed to work in severe frosts and blackouts. Mimax managed to achieve the goal, and today the range of heating equipment is represented by models with power from 7 to 40 kW, which will effectively heat the room from 30 to 400 squares.
Mimax LLC is a EUROPEAN QUALITY AWARD Award winner (2012) for product compliance with EU quality standards.
Technical parameters of gas boilers
The technical parameters of the devices vary depending on the series. The manufacturer offers several varieties.
Vega
Models with one or two circuits, atmospheric burners, high-quality cold-rolled steel heat exchangers and turbulators. With a heating capacity of 7-31 kW, the efficiency reaches 92%. Complete with a gas boiler is supplied Italian automation SIT. Powder enamel was used to color the case. Consider the technical parameters of the series on the example of the model KSGV-31:
- working pressure of the water circuit - 0.2 MPa;
- heated area - 300 m2;
- fuel costs - 3.45 cubic meters per hour;
- unit weight - 131 kg;
- operational period - 15 years.
Features of the Vega series are an integrated gearbox, piezo-type ignition, traction sensors and overheating control.
Parapet devices
The floor view of the devices is characterized by a closed firebox, which allows you to install it indoors without a chimney. Oxygen masses for combustion enter through a coaxial chimney at the intersection of the outer part. The boilers are equipped with non-volatile automation, sectional burners and a rectangular heat exchanger. The characteristic of the KSG (P) -16 model allows us to consider the specifics of the series:
- Efficiency - 92%;
- power indicator - 16 kW;
- installation in an apartment or house up to 160 squares;
- fuel costs - 1.7 cubic meters per hour;
- boiler weight - 64 kg;
- operational period - 15 years.
Parapet equipment is characterized by increased heat transfer.
Titanium
The range is represented by high-power compact models in a stainless steel case of 3 mm in thickness. The combustion chamber is enlarged, the heat exchanger is equipped with a heating element. Connection to the system is carried out in the left and right way. The following specifications are characteristic of the series:
- efficiency factor up to 83%
- operational period - 15 years;
- power - from 12 to 16 kW;
- the presence of a draft regulator;
- heated area - from 120 to 200 squares.
The case of units Titanium is insulated.
Heating systems with one and two circuits
Single circuit equipment only works for heating. At the manufacturer Mimax, it is represented by the series of KSG (IR) and KSG (M). IR boilers are made of stainless steel, equipped with Italian automation, atmospheric Optima burners. Models M are equipped with branded automation ASU-T-M. The technical data sheet of the KGS-16 modification allows us to consider the specifics of single-circuit devices:
- power - 16 kW;
- heating area - 160 squares;
- type of combustion chamber - open;
- efficiency indicator - 87%.
Single-circuit equipment is non-volatile, but is produced without automatic ignition.
Double-circuit units are connected to the heating system and hot water using the main heat exchanger. Water does not get from one circuit to another. Two circuits are equipped with KGSV boilers in a steel casing with a rear arrangement of fittings. Characteristics can be considered on the example of the device KSGV (IR) -20:
- power indicator - 20 kW;
- heated area - 200 squares;
- efficiency indicator - 88%;
- fuel costs - 2.43 cubic meters per hour
- operational term - 15 years.
You can control the temperature of dual-circuit devices using a thermometer on the front.
Solid fuel devices
The solid fuel boiler Mimax runs on wood, pellets, coal and is made in a 3 mm thick steel casing. The entire line is equipped with ASU-TM brand-name automation, the gas control option and thermometers. It includes models KST, KSTG, KSTV, KSTGV. The parameters of solid fuel aggregates can be analyzed on the example of the KSTGV model range:
- heated area - 160 m2;
- power - up to 12.5 kW;
- performance in the DHW circuit - 4.4 l / min;
- efficiency indicator - 87%;
- gas consumption - 1.59 cubic meters per hour.
Floor equipment is equipped with a mechanical control system.
Pros and cons
Gas devices are produced by a domestic manufacturer, so they have the following advantages:
- low cost in comparison with foreign units;
- reliability and high performance;
- adaptation to domestic gas supply conditions;
- the ability to choose a model for a summer residence, apartment, country house;
- the availability of equipment with one or two circuits;
- non-volatility of solid fuel modifications;
- high-quality assembly and durability of parts
- concise appearance.
The disadvantages of the devices include inconvenient ignition, low speed of the coolant and the need to calculate the slope of the pipes. When supplying low-quality gas, nozzles may become clogged.
Mimax boiler design
The device of a gas boiler of the Mimax brand is represented by a burner and 1-2 heat exchangers. The primary element is necessary for heating water when exposed to a burner flame. Secondary is needed for the coolant system.
The manufacturer’s manual notes that special equipment is used to adjust the gas supply. The automatic unit shuts down the boiler in case of emergency risks or critical changes in parameters.
The combustion products of models with a closed furnace are discharged through a coaxial chimney. For models with an open chamber, stove draft is used. When a DHW circuit is connected, a circulation pump can be additionally installed.
The nuances of choice
The selection of heating units is carried out in accordance with the quadrature of the house and thermal power. When choosing, it is worth following the rule - 1 kW of power is spent on 10 squares of the room. In a private house with a total area of 100 m2, it is advisable to operate models KSG-1.5 or KGS-16.
When buying a double-circuit boiler, you need to know that a normal amount of water will be provided by a modification with a power indicator of 20 kW. The KSG-7 device is suitable for a home of 50 squares and will produce 7 liters of water per minute.
Major issues
The malfunction of the gas unit and methods for its elimination are shown in the table.
| Breakage | Cause | How to eliminate |
| Spontaneously disconnected | Bad traction | Chimney cleaning |
| Weak water heating | Confused settings | Correction of automatic parameters |
| The heat carrier heats less than water in hot water | Little water for heating | Checking the installation of the system |
| Problems with the circulation of water in the heating circuit | Little water | Filling system |
| Airlock | Air bleed | |
| Leakage | Search and repair of depressurized area | |
| Scale formation | System cleaning and flushing | |
| Increased gas consumption | Scale in the system | Pipe cleaning and flushing |
| Cotton burner at the time of ignition | Pressure drop | Pressure level adjustment |
The troubleshooting algorithm is indicated in the boiler manual.
Mimax brand produces an extensive line of gas devices. The equipment is affordable, suitable for apartments and private houses. Before buying, you need to determine the technical parameters, power and correlate them with the quadrature of the room.
