Hi, I am looking at putting in a new system where I raise the cwsc in the loft, put the cylinder in there and use a whole house pump to pump 2 bathrooms but not the toilets. Would like it to be as quiet as possible. Any recommendations? Looking at a couple of big shower heads in this and a bath.

Cheers
 
The 'secret' of quietening pumps in a loft is to mount them as close to a solid wall as possible and then to mount on as large a slab of 'proper' paving slab as possible. That minimises rotational pump vibration.
Using proper silicone based flexible hoses will isolate pipe transmitted vibration.
 
What I am actually thinking is getting using a thermal store and putting in a 5 bar single pump and then splitting it for hot and cold. The only thing is, they only have a gas boiler. No wood burner or solar. Maybe they could be persuaded
 
Dab e sys box
 
So, Gledhill say there system is not designed to work off a pump so not sure it will work not being under constant mains pressure. I cannot really see why it would not. Anyone?
 
Yep done a few of there kits and done around 5 pumps off grp ones
 
If your going down the twin pump route then the ct force will be your quietest option running at only 46db. To put that in perspective for you, a dishwasher will generate between 45 and 50db. The next quietest pump is the monsoon by Stuart Turner which runs at 51db.
If you want to switch them to a mains system then I'd go for a grundfos scala 2 and an unvented cylinder. Flow rates of up to 75 ltrs/min at only 46db noise rating and suitable for 8 working outlets at a time.
 
How big 500l ?
 
Here is their reply...

Good afternoon Mr Edwards,


A thermal store is designed to work on mains pressure water. As such there are no manuals or guidance on how to fit one to a pumped supply.

If you can establish a continuous 3 bar supply when required to the plate heat exchanger then you should be able to get the cylinder to work.

However, you need to be aware that in the event the pressure or supply to the cylinder should drop or fail when hot water is being drawn off, you may be at risk of water starvation of implosion of the cylinder – depending how much the pressure drops and how suddenly.
 
So in short they don’t know how to do it / haven’t had anyone ask

Unf not Shaun. If that were the case, then Mira showers would work off pumped supplies like Aqualisa do - but they most def DO NOT.
If they say no then they mean no.

So I can’t use a Mira shower off a well
