Anti-scalding
Regulations for hot water in domestic properties |
|
As of 1st May 2006 a new Scottish Building
Regulation will require that all bath water in a domestic property must be
controlled to a maximum of 48oC. |
| Hot Water Temperature from
Sanitary Fittings |
| Where hot water is provided from storage, building
regulations require a storage temperature of 60oC and a
circulating temperature of no less than 55oC to prevent the
development of Legionella or similar pathogens.
Where water is supplied at high temperature from any source, there is a danger
of scalding to building users. Risk of severe injury increases proportionally
with the increase in temperature and with the extent of contact. |
| Fittings Used for Personal
Hygiene |
| To prevent scalding, the temperature of hot water
discharged from, or to, any bath or bidet should not exceed 48oC.
Where hot and cold water are supplied to a fitting, this
may be achieved by use of a thermostatic mixing valve (TMV) or fitting. Such
valves or fittings should comply with BS EN 1111 or BS EN 1287.
Guidance on the installation, use and maintenance of
thermostatic mixing valves and fittings can be found in
BRE information Paper IP 14/03 or from the
Thermostatic Mixing Valve Association (TMVA) -

| The TMV Scheme |
The Scheme identifies the operational properties of
thermostatic valves or fittings and awards them a classification -
| |
Type 1 |
mechanical mixing
valves with maximum temperature stop (including single lever taps). |
 |
Type 2 |
a
thermostatic mixing valve of lesser
performance to D 08 which conform to EN 1111’s and 1287 (originally BS 1415
Part 2). These can have a maximum temperature stop which is excluded by the
requirements of D 08. |
|
 |
Type 3 |
a
thermostatic mixing valve with enhanced
thermal performance complying with NHS Estates requirements. |
TMV 2 - These are
certified Type 2 thermostatic mixing valves for the domestic market that meet
the requirements of BS EN 1111 and/or BS EN 1287 as well as additional
requirements of the
BuildCert TMV2 Scheme. TMV2 Scheme is working with the
Child Accident
Prevention Trust to promote the safe use of hot water in domestic
premises. |
