I have a customer who wants an unvented HWS, they have a Aqualisa Quartz Gravity Pumped QZD.A2.EV.14 Shower which has a max pressure of 1 bar.

My question is if I fitted PRV's set at 1 bar, on both H & C services to the shower pump once the UVHWS system is installed, would this be sufficient for the shower to operate normally?

Nope time for a new shower if they don't do the high pressure box / control unit
 
FYI, I've contacted Aqualisa and they say I need "our mains compatible HP processor valve which will be half the size of your existing. They can take up to 7 bar of working pressure and are available at a cost of £302.99 including VAT, plus £2.95 for the postage and packaging"
