The message
from "IMM" contains these words:

"The Alpha CD50 condensing storage combi is designed to satisfy the
hot
water and heating requirements of the larger home whilst reducing
energy
consumption. When the store is fully charged an equivalent domestic
hot
water output of 50kW gives a flow rate of up to 18 litres per minute
at
approx 55C - 60C, enough to fill an average bath in about 3 to 5
minutes."

There is marketing-speak in this:

- The specification doesn't say what an average bath is.

The avergage bath is now 80-100 litres. This will fill an avarage bath
in
minutes and never run out of hot water at any time. 3 minutes to
recover
the water store.
