power shower or pumped shower

[mutley racers]

I have been asked to estimate for both. The hot water tank is 110litres and has a big old cwsc. They want it positioned above the bath. The hot water tank is on the other side of the room from the bath so no matter what, some how, I nees to run pipes to this area. Take up the floors, rip out the bath, chase into walls and so on. Or, should I just wack a pump under the bath and come of the hot and cold already there? Not ideal as not separate feeds from tanks to pump. But otherwise, it's quite a big job. All advice muchly appreciated chaps.

Good evening to you all

Just how big is the big old cwcs. You may need an extra tank depending on output of shower. Pump in airing cupboard and pipework best you can.

Over 50 gallons. If need extra water, is it not possible to add a couple more ball valves to cistern for it to fill quicker? I will only put a 1.5 bar shower in I thinks

putting 2 fovs on a tank is no good you need to up the size tank most likely, and the pump should have its own dedicated hot & cold supply the hot should have a surrey flange or similar to stop air getting to pump also

There's only 2 people in the house. I would have thought that the cwsc will be big enough. Do you not think so then? What size tanks do people usually put in for a pumped shower? I have installed a few on a 50 gallon and not had any come backs

most pumps say min 80 gallon, i like to make sure if something goes wrong I've always got myself covered! I've seen showers run off 50 gallon tanks before no problem, not telling you what to do, just saying what I do,

Defo bigger tanks and come of cyl or pump will air lock all day long. U can tandem up tanks.

Two for bigger tanks. I am a naughty boy. I believe just adding another tank in tandem will be best. This will cost them about 900 quids for this install. Blimey

 

[Ermintrude]

Well it's better than costing you £90k in court as some one got a lovely scald!

I tend to have to agree

 

[Chalked]

Cheaper to stick in unvented!

 

[Ermintrude]

900 for unvented and shower? How? Aristion 215l and a Bristan £65

Well chaps, I just downloaded the grundfos shower pump app and it says a min of a 50gallon pump. Even for a 3 bar multiple outlet pump. I still take on all ypur advice as ypu lot are a sensible bunch of guys.

It's a pretty good app I think. Has anyone ever installed a grundfos shower pump?

 

[Ermintrude]

Yes monsoon twin ones.

 

[mutley racers]

Yes monsoon twin ones.

Are they any good? I have only ever installed salamander and Stuart turner

 

[mutley racers]

Yes monsoon twin ones.

Hold on a minute, monsoon are the stuart turner pumps

 

[Ermintrude]

No grunny ones too

 

[mutley racers]

No grunny ones too

Well I never

 

[mutley racers]

How about just wacking a pump on all hot and colds from in the flat? No extra pipework so a lot cheaper

 

[mutley racers]

what external bar showers is everyone fitting at the moment?

 

[mutley racers]
