• Reliable performance. They work flawlessly for a long time. Domestic developers took into account all the features of operation: pressure in main gas pipelines, water quality, low temperatures in winter, and much more. The material of the combustion chambers is carbon steel, resistant to corrosion. The coil, if necessary, is replaced, and the operation of the equipment is extended.
• Galvanized metal with a polymer coating is used for cladding, it prolongs the life of the equipment and gives it an attractive appearance.

Single-circuit

Devices with one circuit – KS-T 16, KS-T 16 RT and others. Thanks to the draft regulator, energy costs are reduced. Thermal power of 16 kW is enough to heat 160 m².

All single-circuit versions are capable of operating on different types of fuel. Efficiency – 85-90%. Thanks to well-thought-out design solutions, heat losses are minimized. The boilers are made of high quality steel (thickness 3–4 mm).

Heaters weigh 120–160 kg.

Dual circuit

These are models KS TVM 16/20, TV 31.5/40, TV 20 and others. A number of double-circuit heaters are easily converted from gas to coal/wood and vice versa. Designed for heating areas up to 300 m². Simultaneously with heating, they heat water for domestic needs.

The secondary circuit is a copper coil, if necessary, it can be changed, thereby extending the operation of the equipment.

A double-circuit boiler has characteristics almost identical to those of a single-circuit boiler. Also made of steel, but more powerful than the single circuit versions. Available in 20, 30 and 50 kW options. Their weight is 150–200 kg.

How to choose

Thermal power. Choosing it, you need to know not only the area that is supposed to be heated. If the device is chosen for heating a private house, you must also consider what material it is built from and how insulated it is.

In apartments, the location is important – central or corner. In the latter, it is always colder, so the power must be chosen with a margin.

The approximate power of the device is determined by the ratio – 1000 W for every 10 squares of area. And for every cubic meter – 40-60 watts. But it is recommended for cold houses and apartments to take boilers with a heat output margin of 30%. Firstly, there will be no problems with heating during the most severe frosts, and secondly, the equipment will not work for wear and tear and will last longer.

Dependence on electricity networks. This parameter is more important for reliability and stability than for efficiency. If the boilers provide for the consumption of electricity, for example for ignition, then it is insignificant.

The number of contours. The choice of this parameter determines the capabilities and cost of the heater. Single-circuit ones are chosen for heating, double-circuit ones, in addition to space heating, can heat water for domestic use.

Installation method. Wall or floor. The choice depends on the size of the room. Wall mounted versions are more compact.

Heat exchanger material – steel or cast iron. Cast iron is more reliable, they are not afraid of corrosion.

Type of combustion chamber. It is more convenient with a closed firebox: they are safer, do not waste the internal air of the premises, they are preferred today by the owners of houses and apartments that are not equipped with traditional chimneys.

How much do they cost

Equipment from domestic brands is a priori cheaper than imported ones, and the products of the Conord plant are no exception.

The price of boilers “Don” depends on the model, its power. An inexpensive single-circuit apparatus KS-T-16, designed for heating 160 m², costs about 17 rubles. The cost of a powerful double-circuit apparatus designed for heating 000 m² is 300 rubles.

Models overview 

Let’s describe the best models.

CS 16

Of all the models presented by domestic manufacturers, one of the most popular is the Don KS 16. Its main advantages are: excellent technical characteristics, convenient operation and economical consumption of energy resources.

Having a domestic assembly and components, it is ready to work in the most difficult climatic conditions. It is the climate of Russia that does not allow many European analogues to compete with domestic developments. This line includes modifications that differ in the number of contours and a number of smaller differences.

Key technical parameters:

KS-T-11                          

Steel. Non-volatile. For small objects. Works on gas or solid fuel – the burner changes.

Features of operation

Each model is accompanied by an instruction in which the user can familiarize himself with the rules for operating the heater, its connection diagram, with design features, settings and adjustments.

The system is filled gradually, at a rate not exceeding 8 l/min. The water is fresh. Filling is continued until liquid appears in the overflow tube of the expansion tank.

Description of the ignition process:

• ventilation of the combustion chamber for 5-10 minutes, the main valve must be closed;
• checking the draft by approaching the paper strip to the viewing window;
• opening the gate for air supply and ignition of the flame;
• closing the door;
• temperature control with coil valve.

Mounting and strapping

The installation of boilers should be done by specialists, but it is useful for even users to know the installation rules. If the piping is carried out according to the gravity scheme, the heater is placed lower than the return pipes – this improves the movement of the coolant. The chimney is located inside the building.

If the chimney passes through unheated rooms, it must be insulated.

Connecting additional equipment

All Conord products are easy to use, but it will not be superfluous to equip the device with a thermostat – this device will make the equipment work as efficiently as possible. You can also purchase an additional coil in advance, in case of a breakdown. As standard, the heaters are equipped with an adjustable front damper.

Reviews

KS-TGVm-16: Nikolai V., Dolgoprudny

Bought for 18 rubles two years ago. The price is attractive, they are much cheaper than the analogues of Proterm, for example, or Buderus. We use any fuel – gas and solid. On natural gas power 000, on solid fuel 20 kW. We heat them for about two hundred squares, plus it also heats the water. It looks unsightly, rustic, but for me the most important thing is that I can always find any accessories for it.

KSts-G-20S: Georgy T., Velikiye Luki

This device has one plus – ease of maintenance. It is easy to understand its principle of operation, to eliminate simple malfunctions. The rest is shortcomings. During normal operation, gas eats up one and a half cubic meters per hour, and if it is minus 25 in the yard, then all 2,5 cubic meters. They promise 92% efficiency, but for me 5 rubles for heating a hundred cubic meters is a bit much.

Floor-standing boilers from the Rostov company “Conord” are in demand among consumers who are ready to sacrifice technological “bonuses” offered by European counterparts. Don heaters are adapted to Russian conditions, reliable and affordable.
