How Much Hot Water?

[sturharv]

Just after some general advice on hot water storage. I have a job at the moment where there is a large extension to a small cafe building, the HW demand will be approx:

Staff WC room (1 whb)
Male toilets (5 whb’s)
Female toilets (5 whb’s)
DIs. toilets (2 whb’s)
Pot wash area (couple of sinks)
Kitchen and cooking area (sinks, dishwasher/s)

I am considering putting a Megaflo (say, 300ltr.) or similar in to do the HW for the full building, can anyone see any problems with this regarding HW demand, I suppose these kitchens etc. only have a few taps although there will be a dishwasher etc. I know its difficult without seeing the job but has anyone done this type of job before, I don’t want to really oversize the HW just for the sake of it.

Thanks

they are liable to leave the pot wash hot taps running continuously at times

Yes thats true.

I'm not dismissing the Megaflo type system as yet, but what are your thoughts regarding a thermal store system with a heat exchanger instead??
