1. Anti-scald Thermostatic Temperature Control Valve
Anti-scald thermostatic temperature control valves are
an important part of domestic water plumbing because
they eliminate the scalding and cold water shocks
that can occur in a shower when a toilet is flushed or a
faucet is turned on. In an Open Loop system (dual
function – space heating and domestic water heating),
an anti-scald valve should be installed when the Tankless
Water heater set thermostat is above 120°F (49°C); refer
to local codes and/or all authority having jurisdiction.
For recommended piping configuration, refer to
Figure 11. Anti-Scald valve shall be thermostatically
controlled and meet at least the following specifications:
