New Salamander CT60B pump squealing noise

[Rackers]

Hi all.

Had this pump installed today and I wasn't expecting complete silence. I was thinking there'd be some vibration but this thing squeals/whines the whole time a tap or shower is running in the bathroom.

Is this right or not?
Pump is installed next to cylinder.

Thanks

No, get the installer back.

What is the cylinder thermostat set too? Anything above 55 degrees and these pump squeal like a stuck pig.

It is set to 60c, I'll turn it down 5c and see if it's different in the morning.

Turn it down further for testing purposes. You'll need to let the cylinder cool a bit too (remember its hotter at the top than it is the bottom).
