In short, the potable hot water argument for a combi in a domestic

And, if you have a water softener in circuit, just not feasible.

You thought that 9lpm was fast enough to fill a bath. I
think that 2-3 times that is becoming more reasonable. If somebody
has only ever had the low flow rate of a combi or gas multipoint, they
may not know that one can do a great deal better.

Stored systems can easily do 45l/m
