TMV (Thermostatic Mixing Valve) Installations

About Our TMV Services

Thermostatic Mixing Valve (TMV) installations play a crucial role in safely mixing hot and cold water. Our expert TMV solutions create an ideal water temperature for use in certain spaces where people need to bathe or wash. 

For example, we serve clients in health and social care facilities. In particular, sectors such as hospitals, care homes, and schools.

Pipe Testing Services has established itself as a leader in the water treatment industry, renowned for high-quality water hygiene services. We offer a range of services, including comprehensive TMV installations, servicing, and maintenance for various environments. Specifically, healthcare and education facilities.

How TMVs Work

With a TMV installation, we mix the right quantities of hot and cold water to produce a stream of pre-set temperature water, typically between 39°C and 43°C. TMVs have a failsafe mechanism that automatically shuts off the valve when supplies fail, effectively preventing exposure to hazardous hot water.

    The Importance of TMV Installations

    TMVs are vital for public water systems, significantly reducing the risk of injury. Shockingly, the U.K. records almost 600 scalding injuries annually, 75% affecting children under 5. Beneficially, our installations protect vulnerable groups – in particular; children, the elderly, and people with disabilities.

    Essentials of TMV Installation

    Every facility may have unique requirements, requiring a specific type of valve. Rest assured, we are equipped to handle any unique TMV installation, regardless of intricacy or location. 

    Healthcare facilities and care homes are legally required to have TMVs installed. Therefore, we carry out this type of work for a range of clients, and always in adherence to governmental legislation regarding health and safety. 

    Following an installation, we conduct regular water temperature monitoring to maintain it within 2°C of the desired setting.

    Risks Without TMV Installations

    The lack of TMVs in publicly accessed environments, particularly health and social care settings, significantly heightens scalding injury risks. Vulnerable individuals, like young children and the elderly, face greater susceptibility to scalding.

    Ensuring user safety requires a thorough risk assessment. Facilities with hot water access should strongly consider TMV installations, highly recommended and potentially legally required in some cases.

    Proper TMV Temperature Setting

    Ensuring the correct TMV temperature setting is vital for safety and compliance. Set the hot water feed within 50 and 60°C, and keep the cold water feed below 20°C. Maintaining the TMV temperature within 39 – 43°C significantly reduces the risk of Legionella and other hazards. Promptly address any deviations in water temperature from the TMV to mitigate potential risks.

    Additionally, we provide Legionella Contractors services, including  legionnaires risk assessments and remedial works for legionella growth in water systems across the UK
