For heating in houses up to 500 m2, which uses solid fuels and natural gas, a universal boiler Don is installed, which is one of the best representatives of domestic equipment. Initial production technologies have been developed for a long time and improved over the years, so the units work efficiently and are durable.
Types of boilers Don
The production uses machine tools from well-known concerns TRU M PF and Amada. The boiler parts are characterized by high dimensional accuracy and quality. Units Don reliably work in different operational conditions and function from 15 to 18 years.
Types of boilers are produced:
- gas;
- solid fuel.
The heat exchanger has an original design and provides for the repair or replacement of the heater.
Gas
Boiler models are equipped with a gas burner. The unit is used in closed and open heating systems. Gas boiler Don 16 does not require regular tossing firewood or pellets. There is no problem of storing fuel and burning waste.
The unit works effectively if the main gas is connected to the house, the connection of cylinders is not recommended if there is no gas tank. Gas does not give soot when burning, and does not clog the chimney and heat exchanger. Discharged products have a temperature lower than that from solid fuels, so no condensation forms on the walls of the structural elements.
Solid fuel
The heating unit is made of steel, cast iron, and the heater is made of copper. Manual or automatic fuel supply is provided, as well as the extraction of combustion products (ash). It uses coal, peat, firewood, coke or fuel particles - pellets. Electronic coordination systems make the equipment reliable and volatile, the device can operate in a single-circuit and double-circuit heating system.
Floor solid fuel boilers Don require regular cleaning of scale and soot deposits. Scale contributes to overheating of the metal and leads to damage. Soot reduces the heat exchange between pipes and combustion products; from this, the energy carrier does not warm up to the required temperature indicators.
Specifications
On some models, the temperature is controlled by a traction reducer. The automation kit includes a supply fan and an operating mode controller.
Characteristics of coal-gas boilers:
- performance - from 16 to 50 kW;
- heats the quadrature of the premises from 160 to 500 m2;
- Efficiency of gas models - 82 - 90%, on solid types - 75 - 80%;
- working pressure of the energy carrier in the coil - 0.6 MPa, in the boiler - 0.12 MPa;
- the heat carrier is heated to + 95 ° C;
- smoke evacuation internal dimensions - 202 x 96 and 252 x 97;
- the dimensions of the boilers are from 0.7 to 0.85 m in length, from 0.47 to 0.7 m in width, and from 1.18 to 1.43 m in height.
Gas units consume from 2 to 6 m3 / hour, depending on performance. The composition of the output combustion products contains carbon monoxide (not more than 119 mg / m3) and nitric oxide (less than 240 mg / m3).
Weight
The mass of boilers ranges from 140 to 270 kg.
The mass of some models:
- KS-T-16 - 153 kg;
- KS-TVm-16 - 190 kg;
- KS-TG-16 N - 155 kg;
- KS-TGVm-16N - 188 kg;
- KS-TGVm-16 / 20N - 200 kg
- KS-TV-31.5 - 266 kg;
- KS-TGV-31.5 / 40 N - 259 kg;
- KS-GV-50 N - 266 kg
The weight of the boiler depends on the dimensions, the number of plates in the heat exchanger and performance.
Boiler device
The water jacket of the Don furnace is made in such a way that the energy source is distributed throughout the entire unit body.The heat exchanger and the casing are insulated with a material with low heat conductivity, so the energy is stored inside, and the box remains cold. The furnace and boiler body are made of steel 3 mm thick.
Mark Don provides the opportunity to replace the copper coil in the water heating system. In hard water, the element quickly fails, replacement extends the life of the equipment. Forced method of removal of combustion products allows you to make a horizontal chimney. The manufacturer gives a guarantee for the boiler 12 months from the date of sale or 15 months from the date of issue, if there is no stamp on the sale.
Advantages and disadvantages
Sheathing is made of galvanized steel, which extends the life of the housing and gives a flawless look.
Units Don have advantages:
- high quality work;
- wide possibilities of service and repair;
- attractive design;
- a reasonable combination of quality and value;
- resistance to sudden changes in pressure in heating circuits;
- fuel efficiency.
The products are certified by a quality document of the international form ISO 9001 - 2011. The products have received many prestigious prizes and awards.
The disadvantages include the small depth of the furnace in the latest models and the lack of an electric heater in a commercial kit.
Features of operation and scope
During operation, do not allow the evaporation of water in the tank to the very bottom. When starting, it is recommended that the filling speed be no more than 8 l / min., The energy source is supplied until water appears in the overflow pipe on the expander. Automation is set to a maximum temperature of + 95 ° C.
It is not permitted to use a connected boiler if the heating is off. In winter, the liquid from the circuits is drained if the unit remains idle for more than a day. The heater is placed below the boiler piping, if the system is carried out according to the gravitational scheme.
The boiler power is selected 30% more than the calculated one if the unit operates in harsh conditions of a poorly heated room or house without external insulation. When choosing, the dependence of the device on electricity is taken into account. If the model does not have electric ignition, you can not connect to the network.
The wall or floor version is selected depending on the size of the heated area, the heating options depend on the ability to connect several circuits and a hot water supply. Models with a closed firebox are used in apartments and houses where there are no traditional chimneys.
The range of boilers don
You need to know the meaning of letters in determining the brand of the unit in order to select the desired model.
The letters indicate:
- K - there is a letter in all brands, says that the device belongs to the category of boilers;
- C - made of steel;
- G - runs on gas;
- B - it is possible to connect a boiler;
- m is a modernized version;
- N - thermostatic automation is installed.
The numbers in the model name indicate the power of the unit.
