A thermostatic mixing valve (or TMV) is a valve that combines hot and cold water to produce a temperature-controlled flow of water prior to it reaching taps, showers and other hot water outlets.
Usually, the hot water of a building is above 60°C. This temperature is constantly maintained to ensure that harmful organisms – such as Legionella bacteria – do not have a suitable breeding ground.
However, water at this temperature does pose a risk as it has the potential to scald skin. For a disabled bathroom user, this could be especially dangerous. For example, some disabled users may be less physically able to feel temperature change, and some would also struggle to move away from the water quickly and safely.
This is why thermostatic mixing valves are essential within accessible bathrooms, washrooms, changing rooms and any other location with a hot water outlet.
To ensure that the water in accessible washrooms is safe for use, thermostatic mixer valves are fitted to the water supply, which brings the temperature down to a safe, comfortable and BS8300-compliant 43°C.
There are additional benefits of installing a thermostatic mixing valve too. Hot water consumption is reduced as it is blended with cold water before being used, and the consistent, comfortable temperature leads to a better end user experience.
The thermostatic mixer valves that NYMAS supplies are in-line with the TMV3 scheme. This means that the mixer valves we supply have met the requirements set by NSF International (formally BuildCert) and have also been issued a certificate granting a five-year approval. The valve is also submitted to the NSF International website, which is constantly updated for accuracy.
Along with being in-line with TMV3 our fittings are WRAS Approved, which ensures that they will not cause waste, misuse, undue consumption or contamination of the water supply.
