Safe boiler

The majority of boiler incidents occur at the beginning of the heating season, when control over the condition of heating systems installed in cottages, residential buildings, and other premises is relaxed. At night, the thermometer can drop significantly below zero, which can lead to partial freezing of pipelines and expansion tanks. They most often freeze in attic spaces if they are not insulated or poorly insulated. Water stops circulating, which sharply increases pressure in the boiler and can lead to an explosion. A large volume of steam released into the room where the boiler is installed increases the overall pressure in the room, resulting in the destruction of the building's load-bearing structures. People suffer injuries of varying severity and steam burns.

TO PREVENT BOILER EXPLOSIONS, IT IS RECOMMENDED TO:

1. Ensure that the shut-off valves on the supply and return pipelines to the boiler are open, as well as all shut-off devices installed on the heating system.

2. Drain condensate from the lower pocket of the chimney for boilers operating with natural draft.

3. Inspect the chimney caps and ensure there is no icing or blockage. If malfunctions of chimneys and ventilation ducts are found, the use of this equipment is prohibited.

4. Before lighting the boiler, open the heating system's make-up line and the expansion tank's fill control line. Water flowing from the control line indicates that the heating system has not frozen. At the same time, it is necessary to ensure that the pressure on the manometer installed on the boiler does not increase.

5. If water does not flow from the expansion tank's fill control line, and the pressure on the boiler, determined by the manometer installed on it, increases and reaches the pressure in the water supply network, this indicates that the heating system has frozen. In this case, lighting the boiler is strictly prohibited.
