Sounds like a plan, except for a few items.
1. A residential water heater used in a nonresidential situation only has a one year warranty.
2.Regardless of whether it is commercial or residential the water temperature is controlled by the thermostat setting.
3. Residential heaters can be set to the unsafe temprature of 160 degrees for dishwashing.
4. It is difficult to pipe heaters in parallel and be sure that they will draw equally as age sets in.
5. Commercial heaters use a lot of fuel, therefore they will operate for a shorter time to reclaim the lost temperature.
5. 199m btu heaters were developed to avoid the ASME rating regulation for heaters 200m btu and over. In a school, the heater should be ASME rated regardless of the btu’s. This precludes using a residential water heater.
