Mixed water temperature
Application
Mixed water temperature
(at point of discharge).
Bidet
38°C max.
Shower
41°C max.
Washbasin
41°C max.
Bath (44°C fill)
44°C max.
Bath (46°C fill)
46°C max.
* For preset outlet temperature adjustment – See page
14 „Commisioning“.
NB.
If a water supply is fed by gravity then the supply
pressure should be verified to ensure the conditions of use
are appropriate for the valve. Valves operating outside of
these supply conditions cannot be guaranteed to operate
as a TMV2 valve.
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 thermo-
static 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 Standards Act 2000, the
maximum mixed water outlet temperature is 43°C
