We recently moved into a house with water under floor heating. In the last 4 months the area heated is slowly reducing with a few rooms not heated at all now. The actuator valves lift so the system is trying to send hot water to the relevant rooms. Can air locks be a problem? We are struggling to find a plumber that specialises in such a system so are not sure what to do....any ideas?
