In an effort to balance my system i have been adjusting lockshields on all my rads.
None of my rads have TRV's on them and the system is 30 years old (boiler is a combi and is 3 years old).
Adjusting the lockshields on the rads has literally done nothing in terms of speed to heat the radiators up, even at a TINY fraction open where you can hear water flow noises there is still no difference, basically all my radiators heat up at the exact same time apart from a new one ive had installed.
Opposite my lockshield valves is the standard manual on/off valve with the cap that turns with the valve.
Is it possible i dont even have lockshields and i just have manual on/off valves on each side of the radiators? One which turns using the plastic cap and one i need pliers to adjust?
