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) - www.tmva.org.uk |
| The TMV Scheme | |||||||||
The Scheme identifies the operational properties of
thermostatic valves or fittings and awards them a classification -
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. |
