Header says it all. Looking for a central heating plumber to un-stick a couple of thermostats and do general service. Ixelles / Etterbeek area.
A few fairly light taps with a hammer (on the metalwork NOT the plastic) should unstick the thermostats.
I can recommend Andy Fish. He has done several works for us and is honest and competent

Becasse I tried that but it is solid, thanks to the high limestone n the water here.
