Tips for the Proper Functioning of Heating Systems

Routine system flushing (chemical cleaning): Over the years, scale, rust, and sludge accumulate inside central heating pipes and radiators. This disrupts water circulation, causing the bottom part of the radiators to remain cold, forcing the boiler to work under extra load, and increasing utility bills by 20% to 30%. The system should be flushed using specialized equipment and chemical solutions once every 3 to 4 years. Expansion tank and pressure control: If the pressure in your heating boiler drops frequently, or conversely, rises sharply when the system heats up and discharges water from the safety valve, the cause is an incorrect air pressure level or a damaged membrane inside the expansion tank. Under normal conditions, the pressure in a cold system should be between 1.2 and 1.5 bar. Cleaning the water filters: A mechanical mesh filter (commonly known as a Y-strainer) is always installed under the heating boiler on the return (inlet) pipe. Neglecting it and letting it clog with dust and debris blocks the water flow, causing boiler noise, overheating, and premature failure of the circulation pump. Removing scale from the heat exchanger: Due to the hard water prevalent in the Georgian market, limescale buildup quickly forms inside the boiler's primary and secondary heat exchangers (where hot water is produced). If the boiler shuts down frequently or the domestic hot water temperature fluctuates constantly in the shower (alternating between hot and cold), the heat exchanger needs to be flushed with a specialized acidic solution. Balancing underfloor heating manifolds: Underfloor heating systems (manifolds/headers) require precise hydraulic regulation via flow meters (linear regulators). Improper balancing will cause rooms closest to the boiler to overheat, while more distant zones remain cold. 💡 Meet winter warmly and peacefully: Find certified heating technicians, authorized central heating boiler repair masters, and underfloor heating specialists on the platform: services.ss.ge
