How to connect an indirect heating boiler "Drazhitsa"? Disadvantages of Drazice boilers

In order to ensure the correct operation of the indirect heating boiler, the wiring diagram must be used during the installation process. At the same time, heating can also be used, and water in the house will be fed to all points of the fence. The piping of the boiler is not complicated, for this purpose it is necessary to use the fittings and materials that are used to connect the boiler to the hot water supply system.

Determining the location of the BKN

If you decide to use the indirect heating boiler "Drazhitsa", then at the first stage it is important to determine its location. If this unit is closer to the boiler equipment, the heat sink will be more efficient, as well as the transfer of heat to hot water supply. The boiler is installed in the boiler room, however, sometimes this component of the system can be found in:

• Bathrooms;
• Corridors;
• Utility rooms.

In this case, the heat sink will not be as effective as in the case of a circuit where the heating equipment is located in the boiler room. But this solution has its advantages expressed in that consumers will be closer to the boiler, the heat loss will decrease as well as the waiting time for hot water.

Boiler installation in the boiler room

Boiler indirect heating "Drazhitsa" can be located in the boiler room, in this case, you can use one of the options for mounting the device. For example, wall-mounted horizontal units are supplied with an armature in a kit for attaching to a vertical surface. Floor boilers do not have fittings, but they will need to be supplemented with stands for floor mounting.

Do not install a floor boiler on the wall, because such an attempt can end badly. If the device, which contains a large amount of water, will fall from the wall, then the entire first floor will be flooded with boiling water. Therefore, the boiler must be installed as planned by the manufacturer.

When the "Drazhitsa" indirect heating boiler is installed, it is necessary to make sure that the output and inlet connections for the outlet and delivery of the coolant are facing towards the boiler equipment. Otherwise, the master has to suffer, arranging the system from the contours, corners and pipes. In this case, the piping of the boiler will be a "curve". With the correct execution of the work, you will get two direct diversions from the system.

Connecting the boiler to the heating and hot water supply

Boiler indirect heating "Drazhitsa" will be connected to heating and hot water. Once you set the device in place, you can proceed with the connection. There are several nozzles in it, namely: the outlet of the hot coolant from cold and hot hot water.

When the circulation of hot water supply is organized, the last two branch pipes will be the outlet of the heated water and the input of the warm coolant. Until the cranes in the fence points are open, the water will circulate through the hot water system, at this point it is heated to the desired temperature. As soon as the faucet opens, the liquid will go to the consumer.

"Drazhitsa" is an indirect heating boiler, which must be connected by two branch pipes in the heating system of the boiler equipment. The other two pipes must be connected to a hot water supply system. If a combined boiler is used, the water will be heated from the heating medium in the heating system and heated by an electric heater until it reaches the consumer.

If hot water works according to the principle of hot water circulation, then a circulating pump must be added to the circuit, it must be installed in front of the hot water inlet. The indirect heating boiler "Dražice-200" is connected in such a way that the device can be excluded from the general scheme if necessary. This need arises during repair and prevention. To do this, you must set the bypass at the outputs and inputs.

Principles of boiler connection

In the unit water will be supplied to two circuits, the first of which is a heating circuit, connected to the house heating system. Another circuit is used for heated water, which is supplied from the water supply system and is discharged to the kitchen or bathroom.

Boiler indirect heating "Drazhitsa-160" is set taking into account the observance of certain principles. Among them, it should be noted:

• The need to supply cold water to the bottom of the appliance;
• The hot water outlet at the top of the unit;
• Supply of coolant into the tank from top to bottom.
• The circulation must be realized in the central part of the equipment container.

It is important to remember that antifreeze or water will be fed into the upper branch pipe, and return back from the lower one.

Tying Options

Most often when connecting an indirect heating boiler, one of three main circuits is used, namely:

• Use of circulating pumps;
• Variant with three-way valve;
• Application of the hydraulic pointer.

Among other things, it must be taken into account that there are options for using a recycling system that improves the quality of hot water in an apartment or house.

Features of using a three-way valve when connecting

If hot water is consumed in a large volume in your home, it is recommended to use a three-way valve when connecting an indirect heating boiler. This creates two circuits, one of them heats the room, while the other is required to heat the water in the device. To distribute the flow between them, a three-way valve controlled by a thermostat is installed.

This system works on a certain principle. As soon as the temperature in the tank drops below the required value, the valve will pump the heating medium into the heating circuit of the device. After the water has heated, the valve returns the flow to the main circuit. The main role in this will be the heating of the liquid in the tank, but not the heating circuit.

"Dražice" is an indirect heating boiler (200 liters), which has a three-way valve. It is recommended for those areas where the water in the water supply system is stiff. In this case, it is worth not to use the dual-circuit boiler, because its elements will fail in a short time.

Main disadvantages

Boiler indirect heating "Drazhitsa", the connection of which can be conducted by you according to the principle described above, has not only advantages, but also disadvantages. High cost is one of the main ones. Sometimes consumers also consider the complexity of the installation as a disadvantage. However, this statement is true only for novice masters who have not previously encountered installation works of this type.

In some cases, the disadvantage is also called the need to install a heat pump, as well as a solar collector. Instruments of this manufacturer are sometimes inertial. If the unit has a high water capacity, it will take a long time to heat up. In terms of size, such equipment outperforms the flow-type heaters by the type of gas columns, so the installation will require not only additional free space, but also a separate room.

Conclusion

The above-described models of indirect heating boilers of the brand "Drazhitsa" are designed and manufactured in the Czech Republic. They can have a horizontal, vertical, hinged and stationary execution. At the same time the capacity varies from 100 to 1000 liters.
