Posted March 20, 20196 yr Can anyone recommend a quiet-ish circulation pump to use in my water heating configuration? Currently I have a GeyserWise setup which works well, but after all this time having it, I'm still slightly irritated by on and off humming of the circulation pump. Seeing as we're moving soon and I have to redo the setup in my new place, I figured I might as well put a bit of thought into the components this time. I realize this component is inherently "noisy", but surely there must be some that are more equal than others? Thought, recommendations?
March 20, 20196 yr Do you have the plastic one or the copper one? I want to recall that the copper one is less noisy
March 20, 20196 yr Author I think it might actually be a plastic one... I'll check it out and keep it in mind. Thanks.
March 20, 20196 yr HI The pumps can get noisy with age... options imo : - remove pump and clean , a lot of the time sand/silica land in impellor housing resulting in resonance when impeller turn ( and agree te older plastic versions more noisy than brass type ). CarEfull when cleaning there are thin spacer washers in the assembly, if you loose this the impellor drag and then the pump do not work - Convert to 220 volt circulation pump ( they are less noisy with higher flow rates) Hope this help
