Do all radiator's need lockshield valves, in our property several are missing?
I assume the radiators are of some age if so in those days they were not fitted .If the system works ok dont bother but if ever you need to turn off a radiator completely ,ie in the case of a leak you will need a valve on each side

Hi All radiators need either two lockshields,or a TRV,and a lockshield! Radiators generally old ones just have lockshield valves,No thermostatic control unless you have a roomstat! All new radiators,upgrading of boiler situations require all radiators to have Thermostatic valves on, with a bypass rad also! just lockshields in the area where roomstat is! This is the best way of saving energy,minimum requirement is in bedrooms for TRVs. I would just fit them in your bedrooms to allow them to be shut off if room is Unoccupied! all others can be kept open, with a room stat if you dont have that already! Consult a good heating engineer,but TRVs everywhere if upgrading,inline with building regs
hope not confusing and helps
