Best way out of this problem is to simply calculate the number of gallons/litres you require at a maximum hourly drawoff from the system and size one to suit that capacity or allow for a storage medium to hold sufficient volume at the right temperature with a smaller BTU input from a heater unit.
Personally I would go for a tankless unit or a number of them manifolded together able to cope with the maximum drawoff demand but also capable of supply economically the smallest demand required.
No storage tanks whatsoever are required for these units and they could be connected to a ring main system which would give instantaneous hot water at any outlet point as needed.
This is a popular way of providing hot water on demand down here and I don’t see why it will not work for you there either.
If you decide to proceed this way have the heaters set at a maximum outlet temp of 60 degrees C to ensure longevity of the heat exchangers within them.
