Radiator maintenance: How and when to bleed air from heating systems

Proper maintenance of heating systems, specifically bleeding air from radiators, is essential for efficient heating and energy savings. Air trapped in the system can cause uneven heating, bubbling noises, or cold spots at the top of the radiator, forcing heating units to work harder and increasing energy consumption.

The timing for bleeding radiators depends on the type of heating installation. For buildings connected to a centralized heating system, the process should be performed after the system has been refilled and the columns are prepared, typically before the heating season begins or during functional testing. For homes with individual thermal plants, radiators should be checked and bled after the circuit is filled with water and before constant use of the system. Following this procedure, it is important to verify the installation pressure according to the manufacturer's instructions.
