I want to replace a noisy ST Monsoon 3 bar pump, and am looking at one of the newer centrifugal pumps. Either a Salamander "Right" pump like the RHP75, or a Techflow QT-2 pump like the QT-80. Does anyone have experience of both these ranges, and which one is quieter? I have a Rexon "whisper-quiet" circular saw that generates around 100db (how do these marketing people get away with it), so suspect Techflow's "whisper quiet" pump is only that quiet when you are wearing ear defenders. Can anyone comment on the relative noise of these two specific models? And is there anything quieter at the 2.5 bar level? Thanks.
Like quiet vacuum cleaners eh? No such thing as a quiet shower pump - fit it in a quiet location such as a loft.
Can anyone answer my original post please? I know shower pumps are noisy. I'd really appreciate a post from someone who is familiar with the two pumps I listed.
I am very familiar with those pumps and have working models in my showrooms - there is NO SUCH THING as a quiet shower pump. The Salamander is by far out the noisiest of the two.
Thanks HOTDOG. How do these two pumps compare noisewise to regenerative pumps from the same manufacturers?
As has been said repeatedly, they are all noisy...although a lot of the noise can be mitigated by siting and installation.
Last year I finished a whole house extension which included 3 Salamander booster pumps to feed the showers. To keep the noise down I mounted them on a piece of 3/4 ply which floats on 100mm of fibreglass lagging in the loft. It works fairly well - so far.
