For heating in houses up to 500 m2, where solid fuels and natural gas are used, the Don universal boiler is installed, which belongs to the best representatives of domestic equipment. The initial production technologies have been developed for a long time and have been improved over the years, therefore the units work efficiently and are distinguished by their durability.
Types of boilers Don
The production uses machine tools from the well-known concerns TRU M PF and Amada. The boiler parts are characterized by high dimensional accuracy and quality. Don units operate reliably in different operating 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 heating element.
Gas
The 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 of wood or pellets. There is no problem of storing fuel reserves and cleaning combustion waste.
The unit works effectively if the main gas is supplied to the house, connecting cylinders is not recommended if there is no gas holder. The gas does not give off soot when burning, and does not clog the chimney and heat exchanger. The discharged products have a temperature lower than the discharge from solid fuels, therefore, condensation does not form on the walls of the structural elements.
Solid fuel
The heating unit is made of steel, cast iron, and the heating element is made of copper. Provides manual or automatic fuel supply, as well as the extraction of combustion products (ash). Coal, peat, firewood, coke or fuel particles - pellets are used. Electronic coordination systems make the equipment reliable and volatile, the device can work in a single-circuit and double-circuit heating system.
Floor-standing solid fuel boilers Don require regular cleaning from limescale and soot deposits. Scale will overheat the metal and cause damage. Soot reduces heat exchange between pipes and combustion products, from which the energy carrier does not heat up to the required temperature indicators.
Specifications
In some models, the temperature is regulated by a traction gear. The automation kit includes a supply fan and an operating mode controller.
Characteristics of coal-gas boilers:
- productivity - from 16 to 50 kW;
- heats the area of premises from 160 to 500 m2;
- The efficiency of gas models is 82 - 90%, for solid types - 75 - 80%;
- operating pressure of the energy carrier in the coil - 0.6 MPa, in the boiler - 0.12 MPa;
- the coolant is heated to + 95 ° С;
- internal dimensions of the smoke extractor - 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 the capacity. The combustion products discharged contain carbon monoxide (no more than 119 mg / m3) and nitrogen oxide (less than 240 mg / m3).
Weight
The weight of the boilers ranges from 140 to 270 kg.
Weight 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 the performance.
Boiler device
The water jacket of the Don furnace is made in such a way that the energy carrier is distributed throughout the entire body of the unit. The heat exchanger and housing are insulated with a material with low heat conductivity, so the energy is stored inside, and the box remains cold. The firebox and boiler body are made of 3 mm thick steel.
Mark Don provides the ability to replace the copper coil in the water heating system. In hard water, the element quickly fails, replacement extends the service life of the equipment. The forced method of removal of combustion products allows you to make a horizontal chimney. The manufacturer gives a guarantee for the boiler for 12 months from the date of sale or 15 months from the date of issue if there is no sale stamp.
Advantages and disadvantages
The casing is made of galvanized, which prolongs the life of the case and gives it a flawless appearance.
Don units have the following advantages:
- high quality of work;
- ample opportunities for service and repair;
- attractive design;
- a reasonable combination of quality and cost;
- resistance to sudden changes in pressure in heating circuits;
- fuel efficiency.
The products are certified by the document of quality compliance with the international form ISO 9001 - 2011. The products have received many prestigious prizes and awards.
The disadvantages include the shallow depth of the firebox in the latest models and the absence of an electric heating element in the sales kit.
Features of operation and scope
During operation, the water in the tank must not be allowed to evaporate to the very bottom. At start-up, the recommended filling rate is no more than 8 l / min., The energy carrier is supplied until water appears in the overflow pipe on the expander. Automation is set to a maximum temperature of up to + 95 ° C.
It is not allowed to use the connected boiler if the heating is off. In winter, the fluid is drained from the circuits if the unit remains out of operation for more than a day. The heater is placed below the boiler piping if the system is performed according to the gravitational scheme.
The power of the boiler is selected 30% more than the calculated one if the unit will operate in the harsh conditions of a poorly heated room or at home without external insulation. When choosing, the dependence of the device on electricity is taken into account. If the model does not have an electric ignition, it is possible not to connect it to the mains.
The wall or floor version is selected depending on the size of the heated area, the heating possibilities depend on the possibility of connecting several circuits and a hot water supply. Models with a closed firebox are used in apartments and houses where there are no traditional chimneys.
Model range of don boilers
