[Bldg-sim] natural gas for school canteen

[John R Ross III PE]

Hi;

I would suggest  AO Smith water heater and boiler  manufacturer sizing 
software available on line at

http://www.hotwatersizing.com/Application.aspx


I have designed and installed several projects including an office 
building cafeteria with gas fired
water heaters combined with a 750 gallon per day Solar thermal array. 
using AO Smith.  Good Stuff.

bye.
