Hi,

I've been looking everywhere for an answer to a problem which has recently
befallen me. I suddenly can't get any hot water in my taps unless the
heating has been on. Is it connected to the fact that I had a very noisy
actuator motor for a couple of months and now I don't hear it at all?

If any one can offer an explanation and, even better, a solution I would

be
very grateful.

Which zone valve do you have with the actuator on it? Makers name etc. Do
you have two zone valves with actuators on them? Or, is it just one zone
valve that had three pipes coming from it?

A two zone system will have two separate zone valves fitted to the boiler
flow (outlet) pipework. Both operate independently to control circulation
through the two parts of the system.

A dual flow system will have one motorised valve, commonly called a
mid-position valve, which allows flow through an either / or situation to
the two separate parts of the heating system.
