In order to ensure the correct operation of the indirect heating boiler, the connection diagram should be used during the installation process. At the same time, heating can also be used, and water in the house will be supplied to all points of the fence. Tying the boiler does not cause difficulties, for this you should use the fittings and materials that are used to connect the boiler to the hot water supply system.
Determination of the location of the BKN
If you decide to use the Drazhitsa indirect heating boiler in your work, then at the first stage it is important to determine its location. If this node is closer to the boiler equipment, then the heat removal will be more efficient, as well as the transfer of heat to hot water supply. The boiler is installed in the boiler room, but sometimes this component of the system can be found in:
- bathrooms;
- corridors;
- utility rooms.
In this case, the heat removal will not be as effective as in the case of the scheme, when the heating equipment is located in the boiler room. But this solution also has its advantages, expressed in the fact that consumers will be closer to the boiler, while heat losses will decrease, as will the waiting time for hot water.
Installing a boiler in a boiler room
Indirect heating boiler "Drazhitsa" can be located in the boiler room, in this case, you can use one of the installation options for the device. For example, wall-mounted horizontal units are supplied with fittings for fixing to a vertical surface. Floorstanding boilers do not have fittings, however, they will need to be supplemented with stands for floor mounting.
You should not install a floor boiler on the wall, because such an attempt can end in failure. If the device, which contains a large amount of water, falls 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 indirect heating boiler "Drazhitsa" is mounted, you need to make sure that the outlet and inlet pipes for the outlet and supply of the coolant are facing the boiler equipment. Otherwise, the master will have to suffer, equipping the system from contours, corners and tubes. In this case, the boiler piping will turn out to be “curved”. If the work is done correctly, you will receive two direct taps from the system.
Connectionboiler for heating and hot water supply
Indirect heating boiler "Drazhitsa" will be connected to heating and hot water supply. Once you install the device in place, you can start connecting. It has several branch pipes, namely: the outlet of the hot coolant from cold and hot DHW water.
When hot water circulation is organized, the last two pipes will be the outlet of the heated water and the inlet of the warm coolant. Until the taps at the points of intake are not open, the water will circulate through the hot water supply system, at which point it is heated to the desired temperature. As soon as the tap opens, the liquid will go to the consumer.
"Dražice" - an indirect heating boiler, which must be connected with two branch pipes in the heating system of boiler equipment. The other two pipes should lead to the hot water supply system. If a combined boiler is used, then the water will be heated from the coolant in the heating system and heated using an electric heating element until it reaches the consumer.
If hot water supply works on the principle of hot water circulation, then a circulation pump must be added to the circuit, it is installed in front of the hot water supply inlet pipe. The indirect heating boiler "Drazice-200" is connected in such a way that the device can be excluded from the general circuit if necessary. Such a need arises in the repair and prevention. To do this, you need to install a bypass onexits and entrances.
Principles of connecting a boiler
The unit will be supplied with water to two circuits, the first of which is heating, connected to the house heating system. The other circuit is used for heated water, which is supplied from the plumbing system and discharged to the kitchen or bathroom.
Indirect heating boiler "Drazhitsa-160" is installed subject to certain principles. Among them it is worth highlighting:
- necessity to supply cold water to the bottom of the appliance;
- hot water outlet at the top of the unit;
- flow of coolant into the tank from top to bottom.
- circulation should be implemented in the central part of the equipment tank.
It is important to remember that antifreeze or water will be supplied to the upper pipe and return from the lower one.
Tie options
Most often, when connecting an indirect heating boiler, one of the three main schemes is used, namely:
- using circulation pumps;
- three way valve option;
- application of hydraulic arrow.
Among other things, it must be taken into account that there are options for using a recirculation system that improves the quality of hot water in an apartment or house.
Features of using a three-way valve when connecting
If your home consumes a large amount of hot water, 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 according to a certain principle. As soon as the temperature in the tank drops below the required value, the valve will begin to pump the coolant into the heating circuit of the device. After the water is heated, the valve returns the flow to the main circuit. In this case, the heating of the liquid in the tank will play the main role, but not the heating circuit.
"Dražice" - 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 hard. In this case, it is worth refusing to use a double-circuit boiler, because its elements will fail in a short time.
Main flaws
The Dražice indirect heating boiler, which you can connect according to the principle described above, has not only pluses, but also minuses. One of the main ones is the high cost. Sometimes consumers also consider the complexity of installation to be a disadvantage. However, this statement is true only for novice craftsmen who have not previously encountered installation work of this type.
In some cases, the need to install a heat pump is also called a disadvantage, andalso a solar collector. Devices of this manufacturer sometimes turn out to be inertial. If the unit has a large water capacity, it will take a long time to heat up. In terms of size, such equipment surpasses flow heaters like gas water heaters, so installation will require not only additional free space, but also a separate room.
Conclusion
The above models of indirect heating boilers of the brand "Drazhitsa" are designed and manufactured in the Czech Republic. They can be horizontal, vertical, mounted and stationary. In this case, the capacity varies from 100 to 1000 liters.
