Bristan tells plumbers to think thermostatic

Chris Tranter, senior product manager at Bristan, has reminded plumbers to choose thermostatic when selecting products for domestic environments.

Mr Tranter says: “When it comes to choosing water delivery products, safety has to be a top priority. It is for this reason that certain hot water safeguards are required under Part G. 

“In 2010, an amendment to the Building Regulations 2000, Approved Document G – Sanitation, hot water safety and water efficiency, mandated that all new build homes would have devices fitted to baths to limit the temperature of the water to 48 degrees Celsius.

“The document went on to note that this would likely be complied with by the fitting of a thermostatic mixing valve (TMV). Already common in showers and in bath fillers specified for sensitive environments, this amendment was designed to tackle scalding in domestic settings.

“Hot bath water is the number one cause of fatal and severe scald injuries in the home, leading to approximately 20 scald related deaths and almost 600 serious injuries per year. TMVs can help prevent these incidents, maintaining the desired water temperature, even if the incoming water pressure or flow rates change.

“Whilst there are viable alternatives to TMVs, for example, temperature limiting cartridges, those erring on the side of caution will note that TMVs are the only solution specifically recognised by Approved Document G. 

“When it comes to domestic compliance, it is vital to choose a provider which is able to offer a full suite of thermostatic products – including the bath filler – in order to remain compliant.”
