Hi!
I am finally getting round to sorting my bathroom out.
We have purchased a shower/bath unit but I need to up the pressure to a minimum of 3 BAR but up to 5 BAR.
I currently have a combi boiler that feeds my existing shower and a cold tank on the 3rd floor (bathroom is on the ground floor). The water pressure is pretty good in the shower but nowhere enough for what we need.
This is my plan:
Fit a large hot water emersion style tank on the 3rd floor and pump it to the shower/bath unit.
Now, as I understand it my shower unit will empty a 160L tank in 8 mins at maximum flow.
On this basis the tank will get very empty and it would take ages for the electric heater in the said tank to heat up that amount of water ready for the next shower.
My plan or thought is to plumb the hot water from the combi boiler into the emersion-heated tank instead of cold, therefore giving me a tank full of hot water in a couple of minutes instad of 30-40 minutes.
I have spoken to my plumber friend who said he had not seen it done but could sort of see my logic…
By my maths I don’t think the combi could supply a constant flow for us to use the shower unit at maximum flow for more than 10 mins but I doubt we would want to anyway. That said we do always shower pretty much one after the other and when we have guests we don’t want to be waiting 30 mins at a time for hot water.
What do the voices of reason say?
Here is a picture of it as you may of fitted one before, hence understand the need for lots of water.

Are there any plumbers near me that want to give a quote for a full bathroom job?
