It appears that by reducing teh pressure th primary heat feed is not pushing through the coil and hence why teh noise had goen away.
I will be getting back to Telford.
I have reduced the pressure in the primary heating circuit that feeds the heat exchanger coil to about 0.5 Bar.
All is now quiet.
Would be interested to hear how others got along.

I have spoken to Telford technical support.
They seemed to admit that this is because the heat exchanger coil is profiled and is more likely to resonate when there are pressure shocks in the system.
This is apparently most likely to happen when the heat supply primary circuit is short -...
I hope to report back later today on where I get with Telford.
The vibrations are all in the heat exchanger coil with no other vibrations anywhere else in the system. And yes, there are pipe clips at regular intervals on all pipe runs.

PS. What was the antishock mini expansion...
I too have just had a Telford Tempest installed. It works fine when heated by the immersion heater but sounds like a Tuba when the heating coil is being fed. I have tried all three speeds on my heating pump but it still sounds like a Tuba.
I have yet to contact Telford but the fact that I...
