The gas boiler Lemax has long been known to consumers in Russia and the former Soviet Union. The equipment produced by the domestic company of the same name is able to heat a house of any size, the main thing is to correctly calculate the minimum power. The manufacturer offers several series of heaters - with promising names Leader, Patriot, Wise, Prime-V and Wester Clever. Each series was developed for domestic conditions. All models have Russified automation, they are easy to maintain and manage.
About company
The history of the brand began in 1992, in the semi-basement of the city of Taganrog. The company, having gone from a mini-firm, has grown to a large plant, and has taken a stable position in the domestic market. The equipment is manufactured on high-tech lines, which allows us to produce competitive products at attractive prices for domestic consumers. The boilers of the Taganrog plant correspond to the ideal ratio of the "price-quality" formula.
Benefits
Judging by the reviews, the products of the Taganrog plant cause users more positive emotions than negative ones. It really deserves approval in terms of design, performance and economy. Its advantages include:
- High efficiency - 90-92%. This is a good feature for domestic gas appliances.
- Appearance - heaters are ergonomically designed, look beautiful in modern interiors.
- Safe operation - provides a reliable, multi-stage protection system.
- Simple connection.
- Long service life - with proper operation and timely maintenance, they can work for a quarter of a century. Warranty - 3 years.
Floor models
Floor-standing appliances make up the lion's share of products manufactured by the manufacturer. And the demand for them is more among consumers. Such versions are usually used for heating a private house - here you need more power and reliability. Wall-mounted versions are more often chosen by apartment owners - but they cannot withstand competition with European brands. The principle of operation is simple - a burner built into the housing heats the heat exchanger of the heating system and domestic hot water - if there is a second circuit. Heat carrier circulation - natural (non-volatile) or forced (volatile). Piezo ignition is used. The gas floor heater is with heat exchangers:
- With steel. Thickness - 2 mm. Steel single-circuit floor-standing boilers are non-volatile and work only for heating. Double-circuit - along the way, they heat water for domestic needs. The models are economical - the gas consumption is almost the same as that of “Vailant”.
- With cast iron. Thickness - 4 mm. The cast-iron single-circuit heating boiler has the best characteristics in the entire Lemax model range. Cast iron is resistant to aggressive environments, is not afraid of overheating. Type of heat exchanger - sectional. Production VIADRUS (Czech Republic).
Mounted models
The wall assortment is more modest. All models are volatile. Automation - Italian production. Settings are factory default. During operation, nothing needs to be regulated. The main thing is to ensure voltage stability. Automation, if desired, is connected to a block of remote thermostats. There is protection against:
- overheating;
- blowing out fire;
- soot formation;
- reverse thrust.
Minus - there is no protection against freezing and pump jamming. Modulation burner, as well as automation - Italian. The modulation principle allows the economical use of gas, provides an increase in the efficiency of the device. Connection is classic. Connection to an ordinary chimney is necessary.
The device boilers "Lemax"
The main components of any gas heater:
- Gas burner block - burner (POLIDORO, Italy), wick (ignitor), piezo ignition. By pressing the button, the piezoelectric element is activated, and the wick is ignited with its help. The main burner ignites from the pilot.
- Heat exchanger. Tubular type, pipes connect to the heating system. It heats the coolant. If there is a hot water supply, you need to consider - when the water heater mode is turned on, the heating system suspends operation.
- Automation. Control board and sensors from NordGas. Gas valve Sit.
- CIMM expansion capacity.
- Wilo circulation pulser.
The company develops its own layout of elements and assemblies, operating instructions, expands the network of service centers. The brand has repeatedly become the sales leader among floor-standing boilers for autonomous heating of private housing and industrial buildings.
Installation
Violation of the installation rules leads to breakdowns and malfunctions. Trusting the installation is recommended to specialized specialists. Installation requirements for Lemax heaters are no different from conventional ones, but there are nuances that are important to consider:
- The automation unit contains a traction sensor. If the products of combustion are not exhausted sufficiently intensively, the burner will turn off. During installation, it is necessary to provide for the creation of conditions for traction. The manufacturer advises connecting the apparatus to a chimney made of sandwich pipes.
You do not have to waste time or material resources for connecting and starting up - everything is done quickly and easily. The settings, as mentioned above, are factory settings, and the adjustment is mechanical.
Automation unit
The gas valve plays a key role here. It is controlled by analog sensors (in non-volatile modifications) or electronic controllers receiving data from electronic sensors (in non-volatile modifications).
The combined type valve is assembled from two valves - simple and electromagnetic. The first is kept open by a spring. During start-up, the second valve is opened by pressing a button - to ignite the wick. It is held for some time - the igniter warms up a special element that responds to heat. This element starts generating electric current - it holds the electromagnetic valve in the open state, the user can release the button. When the igniter blows, the thermocouple cools down - the electric current production stops, the electromagnetic valve closes. Another valve - with a spring, closes after a signal from the draft and temperature sensors.
Possible malfunctions
The equipment of Taganrog manufacturers undoubtedly requires some improvements. Often there are problems with heating water - the devices cannot provide users with the desired amount of hot water in the right amount. Therefore, it is more profitable to buy a single-circuit apparatus, and already connect to it a BKN - indirect heating boiler. You can also choose a hinged or parapet (with a closed combustion chamber) boiler. Possible problems:
- The burner switches off spontaneously. The reason for this may be insufficient traction or damage to the thermostat.
- It smells of gas. Possibly a leak due to poor gaskets in threaded connections - a replacement is needed.
- A long, red-orange flame. Burners clogged or lack of traction.
- Cooled batteries with a hot boiler - there is not enough coolant or errors were made during installation.
Service
Some malfunctions detected during operation can be eliminated independently:
- Problems with traction sensor. It can cause an emergency shutdown with excellent traction. False triggering occurs due to oxidation of the contacts - they need to be cleaned. If the sensor is finally broken, it is easy to change it to a new one.
- Problems with the pilot. Ignition does not occur due to poor combustion of the wick. How to fix the situation? Set the desired flame power. This can be read in detail in the instructions. Also, the connection diagram and data sheet are attached to the equipment.
In almost any specialized store you can buy components and parts to be replaced. Repairs may only be carried out by an employee who has the appropriate approval.

Reviews
Lemax KSG-12 5D: Kirill T., Lagan
I bought it for a summer residence, and I took it in my car - not heavy, compact. Installed with the master - managed in 4 hours, including adjustment. Impressive price and features. A simple device, inexpensive, and it heats perfectly. Automation works great - set up with the master once.
Premium-12.5N: Svetlana G., Odintsovo
It is inexpensive, but it works no worse than expensive imported ones. There is nothing complicated in it - simple operation, adjustment, adjustment. There is practically nothing to break. Reliable heat exchanger. Saving gas consumption. Given how much it heats the area, the price is more than pleasant.
Gas equipment "Lemax" has established a good reputation in the consumer market. These products are especially interesting for owners of private houses - the company mainly produces floor-standing appliances. In the model lines you can find an option for heating any area.
