Main Frequently asked questions What to do if water boils in the boiler

Що робити, якщо вода в котлі закипіла?

If the water in the heating system does not have time to cool down before it reaches the boiler, it will boil. What to do if the water in the boiler boils? Below, we will identify the causes of boiling, as well as what needs to be done to solve the problem and prevent it from happening again.

Most often, such a malfunction is observed in solid fuel boilers of long burning. What to do if the boiler boils? First of all, you need to determine at what stage in the system boiling occurred:

    Immediately after installation and first start-up. A possible reason why the boiler boils is improper connection of elements, inaccuracies in the laying of pipes.
  1. After the system has been working properly for some time. The reason is a malfunction of the circulation pump or air entering the system.
How to lower the temperature in the boiler?

The design of the boiler provides for the possible boiling of water, but it will not be able to function for a long time under such conditions. If the boiler boils, what to do step by step:

  • turn the thermostat to 0;
  • wait for the combustion to stop in the furnace (to speed up, you can remove the coal from the combustion chamber, cover it with ash, sand);
  • open the cleaning holes with the combustion chamber.
All this will allow the boiler to cool down faster. If the system is installed correctly, nothing terrible will happen, so do not panic.
Important! In some boilers, precautions are not provided for boiling the coolant, while the system is sealed, and this situation can cause an accident. It is known when boilers exploded under the pressure of steam generated inside.
If a heating boiler is boiling, in which there are no automatic protective channels for pressure relief, it is necessary to open the air valve on the radiator. This will prevent damage to system elements and pipe connections due to high pressure.

After identifying why the solid fuel boiler boils, it is necessary to eliminate the malfunction. Before that, it cannot be operated. What to do if the boiler boils? The system can be restored by the following actions:

    Correctly set up the circulation pump.
  1. Stopping the pump and thus accelerating the movement of the coolant.
  2. Restoration of normal water flow in all parts of the system.
  3. Installation of a thermal accumulator (TA).
  4. Identification and elimination of possible sources of airborne contamination.
  5. Installation of new batteries or additional sections of radiators.
Knowing what to do if the boiler boils, it will be possible to prevent emergencies and prevent equipment failure. But there are also actions that are unacceptable in this situation. Do not fill the system with cold water and flood the boiler. This can lead to an explosion.

Heat accumulator to protect against boiling of the boiler

Users who have encountered this problem at least once wonder: what to do to prevent the boiler from boiling again? The best solution is to install a thermal management device in the heating system. This will not only prevent troubles in the form of boiling of the coolant, but also reduce the frequency of fuel throwing.

How does it work? When installing a heat accumulator in the hydraulic circuit, the total amount of water increases. And to heat about 2000 liters of water, even the most powerful equipment will need a lot of time.

The circulation pump of the heating system requires a constant supply of electricity to operate. Even a short-term power outage can cause the boiler to boil if the CHP is not installed. In an emergency, the liquid tank will take on excess heat and thus prevent boiling.

In addition, the heat accumulator accumulates thermal energy, reducing fuel consumption and increasing the period between furnaces. TA — this is a complete solution that will make the operation of a solid fuel boiler safe, comfortable and more economical.
