Installation Requirments
Conditions of use for Type 2 (Thermostatic mixer) valves
Maximum Static Pressure (Bar)
Flow Pressure, Hot & Cold (Bar)
Hot Supply Temperature (ºC)
Cold Supply Temperature (ºC)
Note: Valves operating outside these condi-
tions cannot be guaranteed by the Scheme to
operate as Type 2 valves.
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.
Recommended Outlet temperatures
The BuildCert TMV scheme recommends the
following set maximum mixed water outlet
temperatures for use in all premises:
41ºC for showers;
The mixed water temperatures must never
exceed 46ºC.
The maximum mixed water temperature can
be 2ºC above the recommended maximum
set outlet temperatures.
Note: 46ºC is the maximum mixed water
temperature from the bath tap. The maxi-
mum temperature takes account of the al-
lowable temperature tolerances inherent in
thermostatic mixing valves and temperature
losses in metal baths.

Warning: It is not a safe bathing
temperature for adults or children.
The British Burns Association recommends 37
to 37.5ºC as a comfortable bathing tempera-
ture for children. In premises covered by the
Care Standards Act 2000, the maximum mixed
water outlet temperature is 43ºC.
The thermostatic mixing valve (TMV) will be in-
stalled in such a position that maintenance of
the TMV and its valves and the commissioning
and testing of the TMV can be undertaken.
The fitting of isolation valves is required as
close as is practical to the water supply inlets
of the thermostatic mixing valve.
The fitting of strainers is recommended as
close as is practical to the water supply inlets
of the thermostatic mixing valve
