Please note:
If the water supply is fed by gravity then the supply pressure
should be verified to ensure the conditions meet the
minimum requirements of the valve.
For wash hand basins it is assumed washing will be under
running water
• A thermostatic mixing valve having multiple designations
(ie. it is capable of satisfying the requirement of this
specification for more than one application) should be
re-set on site to suit it's the right designations.
• The mixed water temperature must never exceed
46°C at a terminal fitting, this is the maximum water
temperature from the bath, it takes into account the
allowable temperature tolerances inherent in the
thermostatic mixing valve and temperature losses
in metal baths. It is not a safe bathing temperature
for adults or children. The British Burns Association
recommends 37°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.
