Common Issues of Demir Sun 20-Tube Towel Radiator and Their Solutions
The Demir Sun 20-tube towel radiator may experience reduced heating due to improper installation, incomplete air venting, or low system pressure. Reduced heat output is often caused by trapped air in the upper pipes and can be resolved by opening the air vent valve and adjusting the pressure to 1–1.5 bar. Leakage at the joints is another common issue, usually caused by poor sealing or insufficient Teflon tape, and can be fixed by re-sealing the fittings. Surface corrosion may occur if the electrostatic coating is damaged and should be repaired using fine sandpaper and moisture-resistant paint. Unusual noise inside the radiator typically results from irregular flow or sediment buildup, which can be resolved by flushing the system and adjusting pump flow.
