Recommended Outlet temperatures
The BuildCert TMV scheme recommends the following set maximum mixed water outlet
temperature for use in all premises:
The mixed water temperature must never exceed 43˚C.
The maximum mixed water temperature can be 2˚C above the recommended maximum set
outlet temperature.
Note:
43˚C is the maximum mixed water temperature from a shower mixer. The maximum
temperature takes account of the allowable tolerances inherent in thermostatic shower
mixers and temperature losses.
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 Standard Act 2000, the
maximum mixed water outlet temperature is 43˚C.
Installation
Important
: - The following instructions must be read prior to the installation of the
thermostatic shower valve. The installer of the thermostatic shower valve must comply with the
requirements of the Water supply (Water Fittings) Regulations 1999 and also be aware of their
responsibility and duty of care to ensure that all aspects of the installation comply with the
regulations.
It has been brought to our attention that flushing water systems using certain chemicals may
wholly or partially remove the lubricant from the internal workings of the valve, which may
adversely affect its performance. We recommend that following flushing the system with
chemicals; valves are checked for correct operation.
1. It is essential that before installing any thermostatic shower valve to ensure that the supply
conditions of the system to which the valve is intended to be fitted are checked to confirm
compliance with the parameters as quoted within the technical specification and conditions
on which the approval is granted i.e. verify supply temperatures, supply pressures, risk
assessment.
2. Consideration must be made for the possibility of multiple / simultaneous demands being
made on the supply system whilst the thermostatic shower valve is in use, all practical
precautions must be made to ensure that the valve is not affected. Failure to make provision
within the pipe sizing etc. will affect the performance of the shower valve.
