Boiler overview
If you decide to purchase gas boiler equipment from, then you must be prepared for the fact that all models of this supplier are floor standing. Their dimensions are quite large, and the outer casing has a protective enamel. Additional characteristics include 3-mm steel at the base of the case, as well as the ability of the equipment to maintain the desired temperature regime.
The efficiency of the units reaches 90%. They are non-volatile and presented for sale in several modifications. Some models have the ability to prepare hot water for consumption. The units can be of thermohydraulic type automation or SIT system. In the first version, we are talking about non-volatile devices. The thermostat controls the shutdown and fuel supply. When the temperature near the device reaches a certain parameter, gas stops flowing to the main burner, this allows you to maintain the required temperature regime.
Gas boilers "Conord", reviews of which you can read in the article, are well adapted for operation in conditions of not only severe, but also warm winter. They maintain the set temperature with the correct power calculation. The burner is installed with good quality, thanks to this, good productivity is achieved, an optimal gas-air mixture is created and thermal insulation is provided. Due to these features, the gross volume of heat is spent on heating water.
Security systems
Floor standing gas boilers "Conord" are safe and have several systems responsible for this. Among others, a smoke exhaust sensor should be highlighted, which is triggered in the absence of draft, it turns off the gas supply to the burner, as well as if a short-term reverse draft occurs. Such conditions can occur with intense gusts of wind.
The flame on the burner is constantly monitored. If not, then the gas supply is suspended. The temperature in the heating circuit is monitored. Heating of the coolant stops when the temperature reaches a certain value. The described devices function perfectly even at low fuel pressure.
Recommendations for the use of equipment
Reviews of "Conord" boilers indicate that they are chosen mainly due to their reliability and affordable price. However, many consumers complain about one drawback: boilers often go out for no reason... This can be due to such factors:
- the burner is dirty and you need to clean the gas and air supply nozzles with a vacuum cleaner and a brush;
- there is not enough air for the pilot burner to work properly. To fix this, you need to clean the air supply nozzles and improve the ventilation of the room;
- the thermostat contacts are oxidized. You need to clean them up or "stir up" them;
- the draft sensor or the flame sensor is broken.
- Some of the reasons, as you saw, can be eliminated on your own, and to eliminate others, it is better to call the service personnel.
Also, the temperature of the coolant in the system can drop dramatically. To eliminate this, turn the thermostat switch to the maximum position or increase the gas supply to the burner, if such a recommendation is included in the instructions for the boiler.
Also boilers "Conord" have their own features of work in summer... So, to turn off the heating circuit, you need to turn off the tap on the water supply. If only the pilot burner is working, the water heats up in an hour to 60 degrees.If there is no further water consumption, then it will be enough for a couple of hours for minor household needs. After the boiler has heated up, if an active hot water consumption is not planned, it should be turned off, otherwise the water will boil and the boiler may break down.
Overview of marking and its decoding
You can find out about some of the technical characteristics of the boiler if you pay attention to the marking. It may look as follows: KSC-G-10S or KSC-GV-12. The letter "K" stands for "boiler". The fact that it is made of steel is indicated by the letter "C". If the design of the firebox is cylindrical, then you can find out about it by the letter "C".
Gas boiler equipment is designated by the supplier with the letter "G". If in front of you is a boiler that provides the function of hot water supply, then you can find out about this by two letters - "GV". After the letter designation, you will see numbers. They indicate the maximum power level.
In order to determine the required power when buying a boiler, the area of the room is taken into account. For every 10 m2, 1 kW of power will be needed. This is true if the ceiling height is 2.5 m. It is important to take into account that such a choice is relevant for an average level of heat loss.
Boiler device
The device of the gas boiler "Conord" provides for the presence of a furnace, which is made of 3-mm steel. The design has a water jacket, a gas burner device, and smoke tubes with built-in turbulators. The latter are necessary to increase the efficiency.
As for the gas burner device, it is an automation. The unit has a thermal insulation layer made of basalt cardboard. The device has a thermometer to control the temperature of the water. In double-circuit models, there is a coil for the water circuit around the chimneys.
The outlet and inlet of the coolant from the hot water coil is located on the back of the case. The diameter of the thread of the heating pipes is 2 inches, which is equal to 50 mm. For a hot water circuit, this parameter is ½ inch or 15 mm.
Gas boiler for heating "Conord" has a chimney with a diameter of 115 mm. This is true for models that range from 8 to 12 kW. If this value is increased to 16 kW, then the corresponding diameter will be 150 mm. Due to the fact that the design provides good thermal insulation and has built-in turbulators, the efficiency reaches 90%.
These units are capable of operating at reduced gas pressure and are non-volatile, therefore they will operate without electricity. Gas boilers "Conord", reviews of which must be read before buying such equipment, are supplied by the manufacturer with a 15-year warranty for the service life. As for the factory warranty, it lasts for 3 years.
Features of installation of boilers "Conord"
In order for the warranty to be valid during its validity period, specialists from a certified service center must install, configure and commission the equipment. They should also make an appropriate entry in the technical data sheet of the boiler. You should also carry out an annual preventive inspection of the equipment by specialists, which should also be indicated in the data sheet. The absence of such marks will also void the product warranty.
During installation keep in mind the following points:
- if the boiler is to be placed on a combustible floor, be sure to install a non-combustible substrate, which must exceed the overall dimensions of the equipment by 50 cm on all sides;
- in order for the circulation of water in the system to be normal, the lower branch pipe must be located below the heating radiators;
- the pipes of the system can be different.If welding is used for the connection, it is advisable to leave several threaded connections for later repair;
- risers must be vertical, deviation is allowed within 3 mm by 3 meters of the structure;
- horizontal sections must be laid with a slope for air outlet of at least 10 mm per meter of structure;
- bends to heating devices must have a slope of at least 10 mm per meter of pipe;
- shut-off valves must be installed at the exit of the coil;
- the finished chimney to which the equipment will be connected must be located in the load-bearing wall of the building;
- if the chimney passes through an unheated area, it must be protected by thermal insulation;
- chimney diameter must exceed the diameter of the outlet pipe so that the operation of the equipment is stable and the thrust is sufficient;
- the chimney should not have ledges and be strictly vertical;
- all parameters, height and device must meet regulatory documents and fire safety requirements;
- the project for the installation of a gas boiler must be previously agreed with the special authorities.
Review, reviews and characteristics of the most popular models
Floor-standing models from are made of high-quality steel, the surface of the case is protected by a heat-resistant powder composition. The equipment is produced in 4 series. One of them is designated by the KSC-G-S marking. In this case, we are talking about single-circuit devices that are equipped with SIT automation.
This is a multifunctional regulator that is responsible for the gas supply. Equipment power can range from 8 to 30 kW. The temperature can be adjusted between 60 and 90 ° C. The minimum pressure level is 0.2 bar, while the maximum value is 1.9 bar. The price of the gas boiler "Conord KSts-G-8S" is 10,500 rubles.
Reviews of boilers of the KSts-G-N line
Another series is KSts-G-N, which includes single-circuit boilers with thermohydraulic automation. The power range varies from 10 to 30 kW. To increase the efficiency of the work, the structure has a cylindrical shape of a cold-rolled steel heat exchanger. The unit is capable of operating at pressures up to 5 bar.
Considering the characteristics of "Conord" gas boilers, one should not forget about their cost. For example, you can buy the KSts-G-10N model for 11,600 rubles, which, according to users, is an affordable price.
Specifications
One of the main characteristics that attracts buyers is the long warranty period: 3 years, and the service life is 15 years. There are also gas models with cast iron heat exchangers. This is for those who love high reliability. The service life of these units is declared 25 years. The main technical characteristics of steel gas boilers are shown in the table.
Technical characteristics of gas "Conords" (click to enlarge)
The durability of the equipment is ensured by a cylindrical firebox, which better tolerates high pressure, which makes it possible to use them both in systems with circulation pumps and without them. Another "feature" of "Conord" is the absence of an average welded seam in the furnace, since it is made of a thick-walled (3 mm) seamless pipe. Since the seams in the firebox are the weakest point, their minimum number allows us to guarantee such a service life.
Heat exchangers are made of cold-rolled metal, which tolerates thermal deformations better, and they necessarily occur during heating / cooling. The heat carrier in the system with "Conords" is tap water. The use of antifreeze is prohibited.
Reviews about boilers of the KSts-GV-N series
Double-circuit boilers from are also presented by the KSts-GV-N series, which is offered in models with thermohydraulic automation. The minimum power is 12 kW, while the maximum level is at the same limit.
The design of the smoke collector is unique, it has a corresponding sensor, which is responsible for shutting off the gas supply in the absence of draft. With a short-term reverse draft, the stabilization of the boiler operation is ensured by the same sensor. You can purchase double-circuit boilers of this series for 15,000 rubles. This cost, according to consumers, is a little overpriced, but justified by decent quality.
Testimonials
Judging by the reviews, they are mostly positive. There is a certain drawback, namely, a slight sedimentation of soot, but such a nuance is easily removed during the next preventive examination by specialists. But it must be borne in mind that the gas is burned and, naturally, some sediment will still be available.
Some consumers say that they are not satisfied with the need to pay for a preventive examination of the system annually, but this is precisely related to the moments of safety.
In fact, the boilers of this company are a reliable and budget option for a private house and not only.
Reviews about the features of the choice
Gas boiler "Conord KSC" can be single-circuit or double-circuit. The power varies from 8 to 30 kW, which, according to buyers, gives a big run-up for selection. Among the single-circuit models, one should highlight:
- KSC-G-8.
- KSC-G-12.
- KSC-G-20.
- KSC-G-30.

It's no secret that imported floor standing gas boilers are of a higher quality compared to domestic boilers. This also applies to the material for the manufacture of elements, and the reliability of automation, and the assembly of the apparatus. However, the price of imported counterparts is markedly different upward. Our task is to find a Russian-assembled gas boiler with an optimal price-quality ratio.
I propose to disassemble floor-standing gas boilers Conord, reviews of which can increasingly be found on various thematic forums. Consider the model range, technical characteristics, device, types of automation (gas burner devices), using the instructions for use.
Model range and description of boilers Conord
Floor standing gas boilers Conord are available in capacities from 8 to 30 kW. They are, as single-circuit: KSC-G-8, KSC-G-10, KSC-G-12, KSC-G-16, KSC-G-20, KSC-G-25, KSC-G-30; and double-circuit: KSC-GV-10, KSC-GV-12, KSC-GV-16, KSC-GV-20, KSC-GV-25, KSC-GV-30.
Single-circuit can only be used for heating from 30 to 300 m2. Conord double-circuit gas boilers can be used for hot water heating and hot water supply (DHW).
Floor standing gas boilers Conord
It is important to note that if you need a double-circuit boiler for the full use of the DHW circuit, you need to buy a Conord boiler with a power rating of 20-25 kW. In this case, it will deliver about 10-12 liters of hot domestic water per minute.
It makes no sense to buy, for example, a 12 kW KSC-GV-12 double-circuit boiler. He will not give us a good amount of hot water.
The boilers can be used both in open and closed heating systems.
Installation of floor-standing gas boilers Conord
The boiler consists of a steel furnace 3 mm thick, a body, a water jacket, smoke tubes with built-in turbulators to increase the efficiency of the boiler, a gas burner device (automation), a layer of basalt cardboard thermal insulation, and a thermometer to control the temperature of the coolant. In double-circuit models, a special coil for the water circuit is installed around the smoke tubes.
The heating agent inlet and outlet, as well as the DHW coil, are located on the rear side of the boiler drum. The diameter of the thread of the heating connections for all models of this brand is 2 inches or 50 mm. For DHW circuit 1/2 or 15 mm. The chimney diameter for models from 8 to 12 kW is 115 mm, for 16 kW and above - 150 mm.
Boiler device Conord
Due to the built-in turbulators and good thermal insulation, the efficiency of the Conord boiler reaches 90%. These heating devices are capable of operating at reduced gas pressure and are completely non-volatile from electricity. The manufacturer claims a boiler service life of 15 years and a factory warranty of 3 years, which is also indicated in the operating instructions.
Automation for gas boilers Conord
Three types of automation can be installed on floor-standing boilers of this brand:
- domestic type AGU-T-M
- Italian Euro SIT
- American Honeywell
Our domestic automation the most simple and inexpensive. It is installed not only on boilers of the Conord plant, but also on some other models, for example, on Russian-made Mimax gas boilers. Starting occurs manually by igniting with a match or lighter.
In general, the automation, although not particularly intricate, is unpretentious. In the event of a breakdown, it is not difficult to find spare parts for it. For example, a bimetallic plate that often fails costs about 50 rubles.
Automation type AGU-T-M
Euro SIT automation consists of a sectional burner and Polidoro tubes, as well as a safety system: an igniter with a thermocouple, a temperature sensor, a SIT gas valve, a draft sensor and wires. In the event that the pilot burner dies out, the gas is cut off or there is no draft in the chimney, the automation instantly shuts off the gas supply to the burner.
Ignition occurs by pressing the button of the piezoelectric element or using a match. The coolant temperature is provided by the gas valve and is set by the thermostat knob.
Euro SIT automation
Automation Honeywell from an American manufacturer has similar technical characteristics with a gas burner device of the Euro SIT type. The principle of operation is the same, it differs mainly in the manufacturer and in the material of execution of some elements.
Ignition is carried out by pressing the knob to the right of the thermostat and then turning it to the full position for the boiler to operate in economy mode.

Advantages of gas boilers Conord
- a wide range of models - three types of automation - cost-effectiveness - high efficiency - in the event of a boiler malfunction, it is easy to find spare parts - good thermal insulation
Disadvantages of Conord boilers
- build quality - steel thickness no more than 3 mm - price
Price for boilers Conord starts at 13,000 rubles for the most budgetary and low-power model. Still, it's a little expensive. For similar money, you can already buy, for example, an imported floor-standing gas boiler "Protherm Wolf" of Slovak assembly. But it's up to you to decide. Watching the video.
