Hi moved house and we have a gravity system with a worseter boiler and a british gas electro mechanical programmer emp2 drayton sm2. The button sliders are not working properly and i bit broken off in center, my question is do have to replace with this one or could i get a digital remote one or...
So I got the screwdriver and on the radiator with no thermostat I turned both knobs with the pliers anticlockwise and did the same to the non thermostat knobs on the others and yay I have heat , but have I done this correctly ?

Is it possible the ones which don’t work do not have enough water in them ,? And how do I fix that? I am not sure if you can tell from the photos previous which heating system I have ? Such as pressure,combi or conventional?
