Radiator balancing & bleeding
Cold spots, cold radiators upstairs, or a system that's noisy — balanced and bled so every room heats evenly.
About this job
When some radiators roast and others stay lukewarm, the system needs balancing — adjusting each radiator's lockshield valve so hot water is shared evenly. We bleed air from every radiator, check the pump speed, clean the magnetic filter if you have one, and balance the whole system methodically with thermometers. The result is even heat and a quieter, cheaper-to-run system.
