TMV 2 Scheme
The TMV2 scheme was introduced in line with the existing TMV3 scheme. Thermostatic mixing valves are most commonly used in hospitals, care homes and buildings in which the resident is considered to be vulnerable to scalding water. The TMV3 scheme was introduced as a means to regulate and certify valves to NHS standards for use in the healthcare sector. TMV2 valves are designed, produced and tested solely for the domestic market.
In 2010, the TMV2 scheme became part of building regulations in England and Wales to control hot water temperature in domestic bathrooms in baths and bidets, which are considered to be the highest risk. This is achieved by fitting thermostatic mixing valves. The TMV2 certification applies to all new build domestic properties and homes in which bathroom works are being undertaken involving the movement and replacement of bath, bidet or shower outlets. Our TMV2 valves allow water to be delivered at a safe temperature in order to prevent scalding.
Did you know that 570 people every year are admitted to UK hospitals after suffering from severe scald injuries at home? 90% of this number are children. These figures are shocking and work in the case for the use of thermostatic mixing valves.
One of the challenges faced with water temperatures is safe temperatures and Legionella’s disease. Water below 50°C is considered to be safe for a child to avoid scalding, however, water stored below these temperatures is a breeding ground for legionella. TMV2 valves are installed at the discharge point and allow water to be stored at high temperatures but the tmv2 mixes hot and cold water together in order to ensure a safe and stable temperature from the tap and to prevent scalding to the end user.
How does Reliance Water Controls Support the TMV2 scheme?
At Reliance Water Controls, we are committed to raising industry standards and maintaining them at a high level to protect the public and minimise scalding at home. Our involvement in this scheme includes supporting the education of the public to the danger of scalding water. We work with organisations such as the CFBT (Children’s Fire and Burn Trust) and the CAPT (Child Accident Prevention Trust).
All of our TMV products are part of the tmv2 scheme and we continuously develop and innovate to maintain the highest standards and ensure water safety in homes across the UK. Please browse our tmv product pages to find out more about our thermostatic mixing valves and their use in plumbing.
