3.12.5 Sizing the Water System – Water Heaters
Size the pump, piping, and system components required in the water system using recognized
design methods.
3.12.6 Scalding – Water Heaters
This water heater can deliver scalding temperature water at any faucet in the system. Be careful
whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and
automatic clothes washers may require increased temperature water. By setting the water
temperature control on this water heater to obtain the increased temperature water required by
these appliances, you may create the potential for scald injury. To protect against injury, you
should install a mixing valve in the water system. This valve will reduce point of discharge
temperature by mixing cold and hot water in branch supply lines.
Table 3-2 details the relationship of water temperature and time with regard to scald injury and
may be used as a guide in determining the safest water temperature for your applications.
