If you want the house to be warm and comfortable, you will need a well-executed piping of a solid fuel heating boiler. The scheme of this procedure will be discussed in the article a little lower. The piping itself is the installation of all equipment suitable for the heating boiler. As a result of the strapping, a single heating system should be obtained. Often this procedure is done by hand without the participation of professionals.
A bit of general information
Before tying is done, there are a few important things to consider. For example, the pressure in the system and the temperature of the coolant at the outlet of the boiler must not exceed the permissible values. For this, protective devices and warning systems are installed. In addition, the temperature of the liquid (coolant)at the input and output should be approximately the same. In any case, the difference should not be more than 20 degrees Celsius. This requirement is especially relevant for steel equipment, since the formation of condensate inside the housing undesirably affects the durability. Do not forget that the piping 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 hot water tanks, etc. Well, now let's talk about the most interesting.
Tethering open type systems
This scheme is suitable if natural circulation is used. We can say that technically this is the easiest option. This is due to the fact that we will be dealing with a small number of different equipment and devices. The key advantage of such a circuit is that it is completely non-volatile. The downside is that there is no way to regulate the temperature at the outlet of the boiler. Often this leads to an accelerated corrosion process.
During installation, some rules must be observed. For example, to ensure natural circulation, the heating boiler is located 50 cm lower than the heating radiators. In this case, the pipes are mounted with a slope towards the circulation of the liquid, and their diameter must be large enough. The highest place in the system is best suited for installing the expansion tank. The less you use different locking devices,the better the permeability of the coolant will be.
Tying closed systems with natural circulation
The fundamental difference between this method and the previous one is that a closed membrane tank is installed. In priority, its installation should be carried out on the return line of the heating system. At the same time, it is important to comply with the requirement regarding its volume. So, the amount of coolant in the membrane tank must be at least 10% of the total amount of liquid in the system.
The piping scheme for a solid fuel boiler involves the use of a safety valve to relieve pressure, as well as an air vent. Installation of equipment can be carried out separately or in one device, which will be a boiler safety group. By the way, you need to understand that most modern heating equipment already has all these elements in its system, so additional installation is not required.
Piping a gas and solid fuel boiler with forced circulation
To organize forced circulation, you must use a pump. In most cases, its installation is carried out on the return line between the pipe and the tank. The operation of the pump is controlled by a temperature sensor mounted on the return line.
I would like to point out that the use of a pump makes systems more efficient. But in this case, you will need to connect to the mains, which increases the consumption of electricity. The system also requiresuninterrupted and stable electrical connection, therefore it is recommended to install protective equipment, for example, stabilizers or at least fuses. In general, this scheme for piping a solid fuel boiler is extremely relevant and effective.
About the collector connection method
This scheme is used only in systems with forced 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 section of a pipe of large diameter, having one inlet and several outlets of a smaller diameter. Accordingly, such equipment is connected to the inlet and outlet of the boiler.
The advantages of this scheme are that you will be able to turn on the heating devices separately. This is achieved due to the fact that a coolant of the same temperature is supplied to them. It is also convenient to control such heating devices. Among the shortcomings, it is worth noting the high metal content of the collector and the complexity during installation.
Tying a solid fuel boiler with a heat accumulator
This scheme is good because it is suitable for both natural and forced circulation. During installation work, two circulation circuits are required. One is placed between the boiler and the heat accumulator (TA), and the second - between the heat accumulator and the main heating system.
During the operation of the equipmentthe coolant enters the TA. The heat accumulator is a storage tank having a thermally insulated body. 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 piping of a solid fuel boiler with a heat accumulator is also interesting in that even after turning off the heating equipment from the TA tank, heat will be given off for some time. The method is good because it slightly increases efficiency and reduces fuel consumption.
About connecting emergency systems
We have already figured out a little about how the piping of a solid fuel heating boiler is performed. Any scheme, as you can see, can be used, however, a lot depends on the circulation used. But in any case, you must take care of the availability of emergency systems. They are needed to protect against:
- overpressure;
- exceeding coolant temperature;
- preventing condensation on the inner walls of the boiler.
A safety valve should be installed on the supply line when leaving the boiler. Often the valve is built into the boiler, but if it is not, then you can install it manually. A drain hose must be connected to the valve nozzle. This is where excess liquid will go. It can be connected to the sewer or put in a suitable container.
Arrangement of an additional circuit
Option althe circuit is installed to protect the equipment from overheating. The circuit itself has natural circulation and is connected to a DHW tank. If the system is working properly, then the internal pressure closes the additional circuit with a check valve. As a result, the coolant does not circulate there. But when the pump is turned 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 with your own hands, then it is advisable to acquire such a system. It will be useful in many emergency situations.
Installing a thermostatic faucet
So we have already figured out how to tie a solid fuel boiler and an electric boiler, as well as a gas one. As you can see, all schemes are very similar to each other and differ in the additional equipment used. One of these accessories is the faucet. It is necessary to maintain a certain temperature of the coolant at the boiler inlet. 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 from the formation of condensate on its walls. If necessary, the device will open, diluting the cold coolant with hot. That, in principle, is all that can be told about such an event as tying a solid fuel heating boiler. The scheme is selected depending ontype of circulation and heating equipment used.
