That 18lpm is at 60°C though and the store is 60l, which is enough to
fill a bath in 6 mins.

That depends on the temperature of the cold water. If it's 5-8
degrees as it would be in the winter, you won't have put enough in
before the store runs out.

Should just do it, the 60l at 60°C in the store will give 100l of
bathwater at 38°C, leaving 60l of bathwater required for a 160l bath.
The 28kW boiler will give 10l/min at 38°C, so would take 6 minutes to
heat the rest of the bathwater.

What would you consider a reasonable flow rate
for a shower?

Absolute minimum of 15lpm, preferably 20-25lpm per shower.

Fairly high, how long would that be for, 10 mins?

cheers,
Pete.
