Obviously, these will vary a lot between manufacturer and boiler
power etc. However, none of these systems can provide more flow than
your mains supply. If you only have 20lpm from the mains and it is
not practical to upgrade the supply

Many thanks for all the helpful info.

What's the reply likely to be if I call Severn Trent and ask them to turn
the flow up?

'Of course, how high would you like?'
'Of course, that'll be a 50% increase on your current £90/month water
bill[1]'
'Bwahahahaha'

or something else?

connected to your water meter and you end up paying for three years usage in
one.
