UVHWC with low flow and pressure?

[Scott_D]

What would be the lowest flow and pressure you would fit an unvented cylinder onto?
Just doing a quote for a house with a bathroom, en-suite, WC and kitchen so not ideal for a combi.

2.5 bar standing, 2 bar with taps open
16LPM
25mm blue poly incoming main.

Currently got a heat only with OV cylinder and shower pump but it needs replacing and they want the loft clear for future plans.

I generally look for 20-25 l/min, most manufacturer's will quote that as being the minimum too. Explain the pros and cons, free up loft space but potentially cant have two showers running at the same time. Or look to fit an accumulator etc to help maintain flow rate with multiple outlets open.

2 bar minimum 1.5 bar (dynamic) and 20 lpm else you would be better fitting a combi

you got space for an accumulator ?

They don’t really have the space or budget

Would just fit a 111 then great upto 18lpm
