Application
Mixed water temperature
(at point of discharge)
Bidet
38°C max.
Shower
41°C max.
Washbasin
41°C max.

* For preset outlet temperature adjustment – See
page 10 „Commisioning“.
NB.
If a water supply is fed by gravity then the
supply pressure should be verified to ensure the con-
ditions of use are appropriate for the valve. Valves
operating outside of these supply conditions cannot
be guaranteed to operate as a TMV2 or TMV3 valve.
Recommended outlet temperatures
The BuildCert TMV scheme recommends the follow-
ing 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 tempera-
ture from the bath tap. The maximum temperature
takes account of the allowable temperature toler-
ances inherent in thermostatic mixing valves and
temperature losses in metal baths.
It is not a safe bathing temperature for adults or
children.
The British Burns Association recommends 37 to
37.5°C as a comfortable bathing temperature for
children. In premises covered by the Care Stand-
ards Act 2000, the maximum mixed water outlet
temperature is 43°C.
