Plumbing

Accumulator versus booster pump

Anonymous user 03/03/2024 - 3.09 PM

I have been advised by two different people (a mechanical engineer and a plumber) two very different solutions for my house (2900 sqft, 4 bathroom, three floors) 1) installing a TWS MainsBoost Accumulator and a TWS Charger Unit. Or 2) using a Grundfos variable speed booster pump (capable of delivering 50 litres/minute of water). Both people talk very credibly but one argues the other is underspecifying and providing a much noisier solution and the other is arguing vice versa. I would welcome advice as to which path to choose (price is not the key variable for me but obviously a consideration). James - I am trying to renovate my house to provide a good flow of pressure while also having the quietest system available.

Are you a tradesperson and able to answer this question?

What are you trying to achieve? Update: Both systems incorporate a booster pump, you state 'the quietest system available' I have yet to come across a 'quiet' booster pump despite the manufacturers claims! Item (2) must be connected to a break tank which you did not state, if you can over come the noise issue then my preference would be item (2) as you will achieve higher flow rates. As for noisy booster pumps I have in the past created a sound proof enclosure to place over the pump fitted with small air vents to prevent pump motor from over heating and fitted the pump feet on top of a paving slab cut to size then laid a mat of high density rubber between the slab and feet, this helped reduce pump vibration through any surrounding structure.
