If you want the house to be warm and cozy,You will need a well-made strapping of a solid fuel heating boiler. The scheme of this procedure will be discussed in the article a little below. The harness itself is the installation of all equipment suitable for the heating boiler. As a result of the strapping should be a single heating system. Often this procedure is done by hand without the participation of professionals.
Some general information
Before strapping is necessarytake into account several important details. For example, the pressure in the system and the temperature of the coolant at the outlet of the boiler should not exceed the permissible values. To do this, set the protective devices and warning systems. In addition, the temperature of the fluid (coolant) at the inlet and outlet should be approximately the same. In any case, the difference should not be more than 20 degrees Celsius. This requirement is particularly relevant for steel equipment, since the formation of condensate inside the housing undesirably affects durability. Do not forget that the strapping of a solid fuel heating boiler, the scheme of which should be chosen for a reason, requires automation and sensors. In addition, it is desirable to install tanks for hot water, etc. Well, now let's talk about the most interesting.
Strapping open systems
This scheme is suitable ifnatural circulation is used. You can say that in technical terms this is the easiest option. This is due to the fact that we will deal with a small number of different equipment and devices. The key advantage of such a scheme is that it is completely non-volatile. The minus is that there is no possibility to regulate the temperature at the outlet of the boiler. Often this leads to an accelerated corrosion process.
Strapping systems of the closed type with natural circulation
The principal difference of this method fromthe previous one is to install a closed membrane tank. In priority, its installation must be carried out on the return line of the heating system. It is important to comply with the requirement that relates to its volume. Thus, the amount of coolant in the membrane tank must be at least 10% of the total amount of fluid in the system.
The scheme of binding solid fuel boilerinvolves the use of a safety valve for pressure relief, as well as the air vent. Installation of equipment can be carried out separately or in a single device, which will be the security group of the boiler. By the way, it is necessary to understand that most of the modern heating equipment already has all these elements in its system, so additional installation will not be needed.
Strapping gas and solid fuel boiler with forced circulation
For the organization of forced circulationneed to use a pump. In most cases, it is mounted on the return line between the nozzle and the tank. The operation of the pump is controlled by a temperature sensor, which is mounted on the return line pipe.
I would like to note that the use of a pumpmakes the system more efficient. But in this case, you will need to connect to the mains, which increases the consumption of electricity. Also, the system requires an uninterrupted and stable electrical connection, so it is recommended to install protective equipment, for example, stabilizers or at least fuses. In general, this scheme of tying solid fuel boiler is extremely relevant and effective.
About collector connection method
This scheme is used only in systems withforced circulation. The difference from the above method is that in this case, collectors (combs) are used. The devices of such devices are quite simple. In fact, this is a segment of a large diameter pipe, having one inlet and several outlets of a smaller diameter. Accordingly, such equipment is connected to the input and output of the boiler.
The advantages of such a scheme are thatYou will be able to turn on the heating devices separately. This is achieved due to the fact that they are supplied with a coolant of the same temperature. It is also convenient to control such heating devices. Among the drawbacks, it is worth noting the high metal intensity of the collector and the complexity during installation.
Strapping solid fuel boiler with heat storage
This scheme is good because it is suitable fornatural and forced circulation. In the process of installation work, two circulation loops are needed. One is placed between the boiler and the heat accumulator (TA), and the second - between the heat accumulator and the main heating system.
During operation of the equipment coolantenters the TA. A heat accumulator is a storage capacity having a thermally insulated housing. As a result, there is a gradual accumulation of heat in the TA. If necessary, it is given to the heating system. It is worth noting that the strapping of a solid fuel boiler with a heat accumulator is also interesting because even after turning off the heating equipment from the TA tank, heat will be given for some time. The method is good because it increases efficiency and reduces fuel consumption.
About connecting emergency systems
We have already dealt a bit with how it is performed.piping solid fuel heating boiler. The scheme, as you can see, can be used any, however, a lot depends on the circulation used. But in any case, you should take care of the availability of emergency systems. They are required to protect against:
- overpressure;
- excess temperature of the coolant;
- prevent condensation on the inner walls of the boiler.
The safety valve should be installed onflow line at the exit of the boiler. Often the valve is built into the boiler, but if not, then you can install it manually. A drain hose must be connected to the valve port. Excess liquid will go there. It can be connected to the sewer or put a suitable container.
Arrangement of additional contour
An additional circuit is installed to protectequipment from overheating. By itself, the circuit has a natural circulation and is connected to the tank for DHW. If the system is working normally, the internal pressure closes the additional circuit with a check valve. As a result, coolant does not circulate there. But when the pump is shut off for any reason, forced circulation in the system becomes impossible. As a result, an additional circuit with natural circulation is opened, and the coolant is cooled to the required temperature. If you are tying a solid fuel boiler yourself, then it is desirable to acquire such a system. It will be useful in many emergency situations.
Thermostatic mixer installation
Here we have already figured out how the binding is performedsolid fuel boiler and electric boiler, as well as gas. As you can see, all the schemes are very similar to each other and differ in the used additional equipment. One of these accessories is the mixer. It is necessary to maintain a certain temperature of the coolant at the entrance of the boiler. It is best to install the mixer on the return pipeline, and then use a jumper to connect it to the main line. This will protect the boiler against condensation on its walls. If necessary, the device will open, diluting the cold coolant with hot. Here, in principle, is all that can be said about such an event as the strapping of a solid fuel heating boiler. The scheme is selected depending on the type of circulation used and heating equipment.
