Why Your Radiator's Acting Up & How to Fix It
Causes of Cold Spots on Radiators
Trapped Air: Sometimes air bubbles get cozy in your radiator, making the top cold while the bottom stays warm.
Sludge Build-Up: Gunk like rust and dirt can settle at the bottom, blocking hot water flow.
Circulation Problems: If your heating system has issues like an airlock or a faulty pump, hot water might not reach the radiator.
Stuck Valve: Those thermostatic radiator valves (TRVs) can get stuck, stopping hot water from entering the radiator.
How to Fix Cold Spots on Radiators
Bleed the Radiator: Use a radiator key to open the bleed valve and release the air until water starts flowing. Super simple!
Power Flush: For sludge build-up, you can do a power flush with high-pressure water to clear out the debris.
Check and Replace Valves: If the TRV is stuck, try gently tapping it to free it up. If that doesn’t work, it might need replacing.
Balance the Radiators: Adjust the lockshield valves to make sure all radiators heat evenly. This helps hot water flow better throughout the system.
