Hot water to multiple commercial kitchens

[Me9141]

Hi all,

Hope all are well.

I’m in the early stages of renovating an industrial unit. The fit out is to have 7/8 commercial kitchens, these kitchens will have reasonable output, i.e. high street takeaway in terms of their demand.

The unit has 3 bar of pressure and 25 litres a minute of water flow.

What is the best and most economical way of providing the units with hot water. Individual electrical under sink heaters/unvented cylinders/couple of Rinnais etc?

The units will pay for their own water and electricity, gas is covered by landlord.

Any help is greatly appreciated.

Don’t take the job on if you don’t know what you are doing- that’s my advice.

The unit is mine and I am organising the renovation, I am not doing the plumbing work myself. I am merely doing research on the best method to provide hot water. This way I know what kind of heating engineer to go for and who is trying to sell me nonsense.

I manage to scope out the fit out of a rival company doing the same thing this weekend. They used a Andrews Water Heater ECOflo (wouldn't let me post a link), they have 30 kitchens, not sure if they had more than one of these though I only caught a glimpse of one.

Go to the manufacturer's of the units you want and get them to design something for you.

Done this multiple times when doing commercial hot water for kitchens.
Not plugging them - but Rinnai are very helpful and the systems they specify work well.
eg: no complaints.
