How to fill the heating system of a double-circuit boiler

Of course, every person needs to be warm. Therefore, a heating device of any kind is a must. Choosing from all options the boiler is the most popular model in modern time, it is desirable to know its features, nuances in operation and all the details of interaction with it. We will try to analyze all this in detail in this article.

Boiler start

Considering this kind of expansion tank using water as a coolant, it is worth remembering that it is most suitable for use in a private house. Thus, due to the open type of the structure, the liquid only evaporates. That is, there is a natural circulation. As for the process itself, it is heating the coolant at the maximum level. When the indicator reaches the highest mark, the thermal mass enters special registers through pipelines.

In addition, in some devices there are heating batteries. And it is from these products that the temperature with high rates comes. When cooling, the flow returns to its original location - to the boiler. As mentioned earlier, all actions take place under natural circumstances. It follows that there is a high probability of pressure. To prevent it, a specially designed tank is used, which, in the situations described, bleeds water or solution. There is a hole in it, with the help of which the excess part of the coolant is eliminated.

Thanks to this, the user is guaranteed no probability of rupture of the outer shell of the structure. Do not forget also that there are models with a closed type. In such cases, the heat carrier is in a constant position where the pressure is high.

How to fill the boiler

Due to the fact that there are two types of devices, it’s clear that the filling process itself can differ significantly. In addition, there are several options and methods, we will analyze all of them below. Filling with water is not an easy process. The first method will be mentioned through the use of feeding double-circuit boiler.

  • Closed type. It is only possible if there is a connection to the water supply.

ATTENTION! The best option would be to use a ball valve in order to further independently regulate the flow.

  • It is preliminary recommended to renew water, as the old one may already be contaminated. After that, you can open Maevsky cranes and directly recharge. You may notice that fluid has flowed and this is normal. When it ends, it is worth closing all products. When the device is full, you can turn it on. However, monitor the internal pressure with the instrument. With the formation of air jams, it will be necessary to eliminate them.
  • If there is no connection to the water supply, there is no reason for concern. The method will be different, but effective - using a pump. The device itself is a kind of metal tank. To start it, you must perform the following procedure: connecting the hose, filling the tank with coolant, pumping liquid to the center of the device.

IMPORTANT! To protect the boiler from possible breakdowns, it is recommended to observe on the manometer, as in the previous paragraph.

  • And, perhaps, the last way is through a boiler with two circuits. It is considered the simplest of the above methods, since this does not require additional funds. To begin with, it is recommended to open all available air vents. Then open the make-up and completely fill the system with thermal carrier. Then you can close the product. It is important to find out the normal pressure, it can be indicated on the passport of the object itself. It is desirable to achieve it at the end of the process using a pressure gauge.

Features of the first launch

Of course, it would be better if, initially, qualified specialists engage in a double-circuit boiler. Because it is they who will be able to reliably perform the work for sure, as well as verify the previously completed installation and the correctness of the installation. In the future, it will be impractical to call the masters every time, since it takes a lot of time and money. Therefore, it is so important to initially see how professionals do it and remove for themselves the fidelity of supplying coolant to the system.

  • Thus, when starting work, it is necessary to check the presence of correctly connected parts.
  • Then the boiler can be fixed to the power supply.
  • Next, you need to monitor the performance of the bypass and water supply, and also set the optimal pressure.
  • Then you can proceed directly to the launch.

REFERENCE! At this stage, it is important to follow safety precautions.

Winter launch features

Undoubtedly, the question presented is important, since it is necessary to take into account the special temperature conditions of the house and the heating system. Thus, it is very important that the room where the structure is located be warmed up to an acceptable temperature with a plus sign. To do this, you can use any heating devices.

IMPORTANT! The main thing is to stick to the average.

Next, warming up the coolant to 20 degrees, you need to fill a short circuit. Gradually you should move on, but do not forget about the inherent warmth. It is best to do manipulations with a partner who would monitor the necessary pressure and help with the process.
