HW sizing?

[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

300 ltrs

Most kitchens i go to survive on a multipoint.

a 300 ltr would be aqdequate

300 ltrs

This has quite abit more demand than a kitchen (on a multipoint), a 300 would be on the safe side hopefully.

Either that, or go for a thermal store with heat exchanger?

Staff WC room (1 whb)They won`t bother using whb.
Male toilets (5 whb’s)No One will use whb.
Female toilets (5 whb’s)These 5 will be used
DIs. toilets (2 whb’s)"2 wheelchair users@ one time
Pot wash area (couple of sinks)KP will use a lot.
Kitchen and cooking area (sinks, dishwasher/s)D/W manufacturer can supply consumption figures

Im assuming your sizing this for daily consumption? In which case 300 ltrs seems excessive. Does the owner realise what they're paying to be heated everyday. Aswell as the stored water they will need a heat source...Immersions or seperate gas boiler??

Seems a bit OTT for a cafe where people can wash their hands!
