Gas boilers "Ishma" - products of the Lipetsk enterprise "Borinskoye", designed to heat private homes and industrial premises. These single-circuit units with a steel heat exchanger can be cascaded to achieve the required power. They are compact and can heat up to 1000 m². The Ishma brand is a success among domestic consumers, because it offers an attractive price and effectiveness.
About company
The company was founded in 1932 in Lipetsk. Initially, it was engaged in the repair of agricultural machinery. The production of heating equipment by Borinskoye OJSC began in 1992. At first, only low-power equipment was produced, but since 1997, Ishma heating devices have appeared. They are used throughout the Russian Federation and in neighboring countries. Today, the plant produces over 30 modifications of boilers with a heating capacity of 7-100 kW.
Design features
Ishma models differ in power, on which their size and heated area directly depend. But the diameters of the connections are the same for everyone. Options - SIT and SABC automation. The manufacturer presents dozens of modifications with different heating capacities. All heaters comply with GOST 20548.
- The body is treated with a polymer coating, which protects the unit from various external influences. It also increases wear resistance and improves appearance.
- Thanks to the original design of the heat exchanger, the combustion products receive the necessary turbulence. Heat exchanger thickness - 10 mm. Numerous partitions provide coolant circulation at the proper level. This increases the heat transfer and increases the efficiency of the device.
- A well-thought-out stabilization system guarantees stable operation in the most severe weather conditions.
- The design of the gas burner device allows you to get a gas-air mixture with an optimal ratio of components, provides a high density of combustion and noiseless operation.
- The gas valve is equipped with a stabilizer that normalizes gas pressure. Installation of the internal thermostat is possible. There is a possibility of individual adjustment.
- The heater is equipped with two to three types of automatic systems. Moreover, one operates from the mains, and the second operates in the presence of pressure in the gas pipeline.
- To provide hot water supply, a boiler of appropriate performance is connected to the device.

Review of Ishma models
Models may differ in the design of the flue pipe. The Borinsky plant produces floor heaters equipped with atmospheric burners. Power range - 12.5; 25; 31.5; 40; 63; 80; 100 kW The heat exchanger is made of steel. Designed for an area of 70-1000 m². In rooms of a smaller area, it is recommended to install AOGV-boilers. Models of this series can be installed in systems with any circulation - forced or natural. The manufacturer recommends using the environmentally friendly coolant "Olga" - it contains glycerin and does not freeze at low temperatures. Installed automatic systems manufactured by Russian and European manufacturers.
8 models - from 12.5 to 100 kW - are:
- Wall mounted. Power is only 12 500 watts. Single-circuit and double-circuit. There is Italian automation, which is responsible for the auto ignition and stable operation of all nodes at low pressure and at its differences. The work is almost silent;
- Floor standing. From 25,000 to 100,000 watts. Only single-circuit. These models, if the buyer wants, can be equipped with SABK automation.

Mounting
Equipment supplied from the factory is fully ready for installation. To connect the boiler to heating, you need 2-inch pipes - direct and reverse. A safety valve is also needed. The heater is connected to the gas line via an inch pipe at the rear of the boiler. Installation is carried out by specialized organizations. To obtain permission for the implementation of the project, the premises must meet the requirements of:
- Equipped with a ventilation hood;
- Air enters through the slots of the door and window openings in a ratio of at least 10 m³ for each cubic meter of gas;
- If the room is completely hermetic, it is necessary to organize ventilation.
If one heater is mounted, the distance from the wall to its side should be at least 15 cm. At the same time, a passage from 50 cm should remain on the other side.
How to light a cauldron
The water that the system is filled with must comply with GOST and SanPiN. The maximum hardness is 0.7 mEq / kg.
- Before igniting the wick, check the shut-off valves - they must be closed and the temperature control knob turned off;
- Make sure that there is traction by holding a strip of paper at the chimney hole. If there is no draft, it is forbidden to kindle the burner;
- Open the gas line tap - feed the burner;
- Light a match or a bundle of paper, bring to the igniter. Press the start button. Keep it pressed for about half a minute - no less. Having released the button, be convinced of stable burning of gas on an igniter. After waiting 5-10 minutes until the furnace warms up, and making sure the igniter is stable burning, you can proceed to ignition of the main burner. If the fire goes out, re-ignite.
It happens that at the first start the ignitor does not burn due to air accumulated in the gas line. Then the button should be kept pressed for at least 2-3 minutes. Re-igniting, you need to wait 5-10 minutes for the firebox to ventilate - then there will be no cotton.
Malfunctions
Each model is accompanied by an instruction manual. It will help diagnose the malfunction and indicate what to do in each case. The most common damage:
- Burner or igniter goes out. The probable cause is carbon deposits on the thermocouple or lack of contact in the circuit. The solution is cleaning the thermocouple and airing the firebox. This must be done by shutting off the gas supply valve. Did not help? Then you have to change the thermocouple. Another possible reason is that the solenoid valve is defective.
- The flame turned yellow. Smoking burner. The reason is traction problems. The chimney is clogged or blown.
- Poor water heating.
- Water shortage in the system. It is necessary to add the coolant to the expansion tank - with an open (gravity) system. If the closed version with a circulation pump, then the coolant is added through the feed tap.
- Unable to adjust coolant temperature at the output of the device. Or she exceeded 90 ° C. The reason is that the temperature regulator is broken or depressurization has occurred.
- Unable to light the wick - the fire is weak or intermittent. The solution is to clean the igniter nozzle and check the gas tightness.
- Cannot light the main burner. Or burning is weak, fading. Probably burner nozzles clogged. You also need to clean the gas filter.
- I can’t turn off the burnerand the fire is not regulated. The bellows thermoball is broken. Need to change.
- Clapping sounds are heard during ignition. The location of the igniter was disrupted - it shifted relative to the main burner. The solution is to call a service employee.
Reviews
Ishma 31.5: Alexander P., Mozhaysk
I decided to choose a simple domestic heater - simple and inexpensive. It works without breakdowns. Heats the house with an area of 300 squares, warm even in the most severe frosts. Virtually no noise - the main thing is to configure everything correctly. One circuit - no DHW. Gas consumes a lot - 3.7 cubic meters per hour. The temperature on the heat exchanger is at least 60 degrees. The device is heavy - more than a centner, so delivery and installation were not easy. Pros - convenient, economical, easy to find parts. Cons - weighs a lot.
Ishma 31.5: George T., Pyatigorsk
Doesn’t work normally. The main drawback is that the igniter often goes out. He invited the emergency service - they cleaned it, but did not guarantee normal operation. We have to clean the nozzle, and the masters cleaned, and everything is repeated. They say that the thermocouple is poorly designed. So I think, something else to put - non-native. Or does the boiler change at all? Last winter, this thermocouple nearly froze. For a long time, the smoke detector bothered me. First replaced it, then made a direct connection. I worked for six months and goes out again.
Borinsky boilers are distinguished by an attractive price-quality ratio in their segment. A large number of modifications allows for each area to choose the option with optimal performance. The presence of service centers and inexpensive spare parts are the key to operational maintenance and troubleshooting. Their device and principle of operation compared to the European analogs - yesterday. However, they can work properly, performing their main task - high-quality home heating.
