Hi i am opening a restaurant soon and am getting a megaflow to serve my hot water demand. There will be two kitchen sinks and one sink in the bar, and three wash hand basins. The restaurant will be open from 12pm to 11pm with obvious busy periods at lunch and in the evening. Sinks will mostly be used for only a small about of dishwashing as we will have 2 dishwashers running off cold mains i believe. The question is what size tank do i get to suit the demand? Any advice on this would be greatly appreciated. Thanks
