New year ; old case - tomorrow ?

The Combi is a leased item .

Well ! ive got to spend more dosh. Header tank onto gravity fed triton electric t90xr ( I think ) - quieter than the Mira . A solution at least !!

Lol ! That makes more sense ! i believe you can get collapsible tanks just so they can fit through tight spaces ? This and a gravity fed electric shower best solution ???

Or swapping the electric shower for a gravity fed one ?

Argh!; knew this issue would come back to bite me. Might a *simpler* solution be to ditch the electric shower and just have it as a mixer running off the UVC same as the others? (UVC will struggle with 5 showers simultaneously - but I guess that's expected and acceptable ......)

How does this coffin tank help? . If it's only 25 litres it will drain fast then 'underflow' on electric shower again..... Guy on phone suggested an electric shower consumes approx 10 litres a minute. So for 2 consecutive showers (being pessimistic of course) 200 litres.

Shower is 1st floor Spoke to pump express they suggested a "power tank" - tank with a pump ; 1.3k!!!! plus I need to know my flow rate etc.!!

This the type of thing? https://pumpexpress.co.uk/shop/pressurewave-series-24-litre-inline-pressure-vessel/ I *assume* you only get half the volume due to the diaphram . So what size should I look for?

Right! My builder tried using the the shower as the first device in the cold water main and (you won't be surprised) it didn't make enough difference. So!; can I have a tank recommended for this. It's only feeding 1 electric shower so I *guess* should be able to supply 2 successive showers i.e. enough water for 2 people to shower independently. I know he thinks it will fit in the loft area (I have a loft room) - also the access hatch to the eves is very small. But anyway!; please links to a suitable tank. The builder has asked me to show him the product - then if it fails it's my fault ?

I’m not familiar with that ; but can only imagine them tiling in a provocative manner!!

Working on New Year’s Day ! A sin surely ! ?

I don’t know . Depends which year ?

Disgusting forum ! ?

Bonus !

All nuns are { very nice people } in my experience

No - it’s a different incompetent ?

You think the builder will admit he’s wrong and listen too me ; a non plumber !! ? Let him try ; maybe fail ; then a tank .

Or perhaps not . Don’t bend down !

I know I know Right at the start I showed him your diagram but none of them ‘understood’ it ffs ! i’ll let him try this feed of the main ; if that fails he will have to install a tank somewhere . No good in loft as a room now !

Electric shower is communal- 2 bedrooms need it as not ensuite . Builder wants to try his cheaper method first of course ! Otherwise he’s liable for extra costs ...

I guess there must be a proper way to work this out? By that I mean real physics ....

Builder wants to try re-routing the cold direct to the electric shower. I guess there's no way of knowing if this will work i.e. with 4 UVC showers running ; until we try it

Not sure - hence roofer to check The upstand is currently timber .
