TMV2 mixing valves are used in domestic settings, small business premises, and commercial or public buildings. The maximum static water pressure can withstand up to 10 bar in line with BS EN 1111 and BS EN 1287 requirements. The high flow pressure for hot and cold applies to BS EN 1111 and must be between 0.5 and 5.0 bar, whereas the low flow pressure for hot and cold applies to BS EN 1287 and must be between 0.1 and 1.0 bar.

This means that the standard of TMV2 valves meets the BS 8300 requirements, and there should be no concerns about the functionality or compliance of this valve when developing a commercial washroom.

There is a misunderstanding that accessible washrooms in commercial buildings must incorporate TMV3 valves for taps and showers because there is a relationship between healthcare and accessibility. This is not true.

For two reasons – for safety and in accordance with the regulations. For the safety of those using a tap and to avoid injuries such as scalding, a tempering valve or TMV ensures the water being released from the faucet is not above 60°C (140°F) for tempering valves or 45°C (113°F) for TMVs. Additionally, in accordance with Australian regulations (National Plumbing and Drainage Standard AS/NZS 3500.4: 2003), various water installations are not permitted to deliver water at a temperature higher than 60°C/45°C for different fixtures.

TMV3 valves are a legal requirement for UK healthcare premises but are also suitable for washrooms in commercial developments such as office buildings and public environments.

As you can see, the differences between the conditions of the thermostatic mixing valves are slight. But the TMV topic is still creating much confusion amongst architects, contractors, building officials, and health engineers, leading them to believe that TMV3 valves are considerably better than TMV2 and more suited for Doc M washrooms.

Tempering valves are adjustable and temperature-activated, meaning they moderate hot water flow when necessary to ensure water isn’t too hot when it is delivered to a tap. Hot water that is stored in a hot water storage system should be kept at a temperature of at least 60°C, however, water should be delivered through a faucet at a maximum of 50°C. A tempering valve works by blending hot water with cold water so it flows through your tap at the correct temperature, within 3°C +/-.

A qualified plumber can install a tempering valve, however, a plumber with a TMV licence is the only one who can install a thermostatic mixing valve.

The NSF TMV2 approval Scheme provides an easy approval guide that refers to testing, pre-approval requirements, recommended maximum mixed water outlet temperatures, operating conditions, full and factored approval, and details about the information and maintenance documentation.

TMV3 valves are only mandatory for healthcare environments, whereas TMV2 valves are perfectly suitable for commercial and public washrooms because they meet the Harmonised British Standards, making them compliant with the UK Building Regulations.

TMV2 valves operate the same way as TMV3 valves with a maximum temperature stop and temperature regulator that copes with high water supply conditions. However, the difference is this thermostatic mixing valve must conform to British Standards as specified in BS EN 1111 and BS EN 1287.

A TMV3 mixing valve is certified to comply with NHS requirements issued by the Department of Health in the Health Technical Memorandum 04-01: Supplement – Performance specification D 08: thermostatic mixing valves (healthcare premises), 2017 edition. A third party tests and approves TMV3 valves to ensure they conform to the construction, sampling, leaktightness, durability, designation, installation and operating instructions, commissioning and in-service tests requirements, marking, and performance.

When you turn the tap on in your home or workplace, you expect water at the correct temperature to be delivered – whether that be hot, cold, warm or something in between.

The British Building Regulations have authority over TMV2 standards, and the UK Department of Health has authority over TMV3 regulations. But remember, this does not mean one TMV is more compliant than the other. Both TMVs are compliant, but the only exception is that TMV3 valves are a legal requirement for UK healthcare premises.

These mixing valves have enhanced thermal performance features and a temperature stop that allow a quick response time to loss of water pressure or changes in water temperature. TMV3 valves can also cope with extreme supply conditions and work at a maximum static water pressure range of up to 10 bar. High flow pressure for hot and cold ranges from 1 – 5 bar, and low flow pressure ranges from 0.2 to 1 bar.

Your water heater needs an expansion tank if you have a closed plumbing system. Here's what that means and how to tell if you have one.

Both thermostatic mixing valves are measured and tested in different ways according to each of their standards, therefore it is not possible to make a fair or direct comparison on which one is better.

Thermostatic mixing valves are temperature control elements commonly found in shower valves and plumbed into sensor taps controlling the mix of hot and cold water at the point of use. These elements protect users from scalding and manage the temperature at a safe level. These mixing valves are typically classified as TMV2 and/or TMV3.

A tempering valve is a temperature-sensitive 2-inlet or 3-inlet mixing valve which pulls water from your hot water system, mixes it with cold water and delivers it to a faucet. General household use requires hot water to be no hotter than 60°C, however, appliances such as dishwashers and washing machines may have differing settings.

pre-pressurized diaphragm type inlet connections: 3/4" NPT Pre-charge Pressure 20 PSI.

TMVs are generally used in environments that include high-risk persons, such as children, the elderly and the sick, that require a lower water delivery temperature (usually 45°C or 113°C as a maximum).

BS8300 also specifies that the temperature at the outlet must not exceed 43⁰C for basin taps and shower fittings and the temperature of the water circulating in the pipework must be at least 60°C to avoid the risk of Legionella.

A thermostatic mixing valve, or TMV, is a great little gadget that blends both hot and cold water together to achieve a particular, predetermined water temperature when delivering water through a faucet.

BS 8300-2:2018 – Design of an accessible and inclusive built environment – Part 2: Buildings – Code of practice, stipulates “The temperature of hot water supply at an outlet can be controlled by use of an appropriate in-line blending valve or other temperature control device in accordance with either BS EN 1111 or BS EN 1287.”

When designing accessible washrooms, Document Part M of the Building Regulations stipulates that these washrooms must comply with BS 8300 standards – BS 8300 standards refer to BS EN 1111 and BS EN 1287. Thus, TMV2 valves conform to the relevant building regulations within the washroom environment and are acceptable for installation in commercial accessible washrooms.

Tempering valves are required to be installed in the following situations (in accordance with the Plumbing Code of Australia):

The WELL standard requires a thermostatic mixing valve for taps that blend hot and cold water at the point of use to enhance washroom accommodations.

Thermostatic mixing valvehow it works

Depending on the set water temperature, the element within the thermostatic mixing valve expands or contracts and changes the proportion of hot and cold water mixed in the valve.

A TMV works by mixing hot and cold water together to achieve a particular temperature (within 1°C +/-) to be delivered in various. The temperature is usually preset by a plumber or a qualified tradesperson who has installed the device, and the element within a TMV that is sensitive to thermal activity automatically arranges the appropriate levels of hot/cold water to create the correct temperature of the liquid.

A TMV2 is suitable and compliant with UK Building Regulations for any standard commercial washroom. But within the healthcare sector, it is mandatory to install TMV3 valves as specified by the UK Department of Health performance specification D 08.

This means that all hot water system replacements should have a tempering valve installed. Some hot water system repairs do not require a tempering valve to be installed, but we suggest speaking to your plumber anyway to see if this is an option (it should be!).
