I was looking in to balancing my radiators but only 2 have the "lockshield" valves. Each has a TRV all upstairs rads also have a valve with + and - symbols on, can these still be balanced in the same way as rads with a lockshield?
What's best way to use a balanced system with the TRVs on highest setting or each room different ie lower setting for unused rooms?
Thanks for any help.
