Radio interference from flowshare valve

[Mary Fisher]

This is not constant, it began this morning, continued for an hour or so and has now stopped.

There's a new boiler, programmer and associated technology in the revised hot water/ch installation which I'm happy to describe if asked for details but I don't know what might be relevant. The (diy) installation was completed a couple of days ago and, as far as we know, didn't affect the radios before. They're playing in all rooms all day long so we would have noticed it.

The timing of the radio interference - on every radio in the house (we don't have a tv) - is exactly the same as the 'ticking' of the valve, which is a Honeywell V4073

Can anyone suggest a cause, please? And if so, a remedy?

TIA

If you disturbed the wiring to the valve, it may be that one of the connections has become high(er) impedance, forming a transmission line. Check tightness/security of connections, maybe add a ferrite ring looped through the lead to the solenoid if there is still a problem.

There was no disturbance, it was a new installation.

It's been double checked.

Thanks for that, something to consider if it happens again.
