Hi, I'm new on here and just looking some advice. We occasionally stay in a relative's apartment. The gas boiler fires up and twenty minutes later the radiators are still stone cold. In the hot cupboard a pipe is roasting below a motorised valve and lukewarm above it. I moved the lever to manual and the radiators warmed up. The rest of the week the heating worked fine. Over the last few years this seems to be the way it goes. I suspect the valve underneath the actuator is sticking and the actuator is unable to open it automatically and a few manual turns with the lever frees it up.
My question is: Can the actuator be removed and the valve freed up manually or does the entire system need to be drained and a new motorised valve installed? Thanks.
