Important! The fitting of any flow regulator will invalidate TMV2 compliance
due to the minimum flow rate requirements. Do not fit flow regulators in TMV2
applications.

Recommended Outlet Temperatures
The BuildCert TMV scheme recommends the following set maximum mixed water
outlet temperatures for use in all premises:
44°C for bath fill, but see notes below;
41°C for showers;
41°C for washbasins;
38°C for bidets.
The mixed water temperatures must never exceed 46°C.
The maximum mixed water temperature can be 2°C above the recommended
maximum set outlet temperatures.
Note! 46°C is the maximum mixed water temperature from the bath tap. The
maximum temperature takes account of the allowable temperature tolerances
inherent in thermostatic mixing valves and temperature losses in metal baths.
It is not a safe bathing temperature for adults or children.
