Do you mean on standby or actively pumping? In most cases these are controlled by a pressure valve with no current flowing unless a tap is opened. When running it'll consume whatever power it's rated at.
Have a similar issue….anyone found a less noisy pump,- salamander or Stuart turner one/anti vibration mat/putting Kingston in the hot press///any other advice ?
We have a Stuart Turner Monsoon in the hot press beside the kids room, never wakes them. Sits on one of these anti-vibration pads and connects via flexi-hoses with a little play.
I’ve a lowera pump and i recently got a new cylinder and high pressure water to all taps etc but the noise is unreal in the hot press…not sure I can stick it !!
