Thermostatic Mixing Valve: The Ultimate FAQ Guide

Having an accurate thermostatic mixing valve for your specific application is crucial.  

This scholarly article answers common questions about the performance and characteristics of a thermostatic mixing valve. 

Enjoy reading and learning!

What is a Thermostatic Mixing Valve?

A thermostatic mixing valve regulates the water temperature of the distribution system. 

This valve also ensures a high temperature for boilers to stop sustained flue gas condensation. 

Additionally, a thermostatic valve prevents burns due to water temperature changes.

Do I Need a Thermostatic Mixing Valve?

Installing a thermostatic mixing valve for your heater is essential. 

It helps prevent scalding and handles water flow temperatures. 

The thermostatic mixing valve helps kill off harmful bacteria from the water.

What are the Benefits of Thermostatic Mixing Valve?

• Prevent Scalding

Using a thermostatic mixing valve allows you to choose a comfortable shower or sink water temperature. Setting preferred water temperature prevents scalding.

• Prevent Thermal Shock

The thermostatic mixing valve helps prevent thermal shock due to a sudden change of water temperature. 

• Inhibiting Legionella

Installing a thermostatic mixing valve prevents you from using turned-down water from the heater that is vulnerable to bacteria.

• Exterminate Inconsistent Water Temperature

Inconsistent water temperature can either freeze or burn your skin. Using a thermostatic mixing valve helps prevent such situations.

• Secured Feature

The thermostatic mixing valve can cut off the water supply when changes in water temperature occur. 

Using this valve assures you safe features and utilization.

• No Extensive Changes

A thermostatic mixing valve is easy to install, and no extensive changes are required. 

Installing the mixing valve doesn’t need digging the tiles and walls. It prevents property damages.

How Does a Thermostatic Mixing Valve Work?

The thermostatic mixing valve achieves the user’s preferred temperature.

This valve quickly stops temperature and pressure changes or fluctuations.

It happens when you readjust the mixed cold to have a consistent water temperature. 

What are the Components of Thermostatic Mixing Valve?

Return Spring – The piston expands when water temperature changes. The return spring pushes the piston to its typical setting.

Thermostatic Element – This component contracts and expand according to water temperature. The thermostatic element quickly moves the piston up or down when temperature changes occur.

Piston – The piston is the one that moves when shutting off hot and cold water flows. It moves according to the thermostatic element sensor.

Temperature Adjuster – The temperature adjuster adjusts the temperature in the valve. This component changes the piston to its proper position.

Is the Thermostatic Mixing Valve Worth It?

The thermostatic mixing valve saves money and someone’s life. 

Installing this valve saves someone from scalding. 

What is the Difference Between Mixing Valve and Thermostatic Mixing Valve?

The mixing valve operates about 3℃ +/, while the thermostatic mixing valve keeps the water to 1℃ +/-.

The thermostatic valve responds quickly compared to a mixing valve.

What are the Applications of Thermostatic Mixing Valve?

The thermostatic mixing valve is explicitly formed for facilities like:

• Hospitals
• Childcare centers
• Nursing homes
• Schools
• Shopping center bathrooms
• Aged care centers
• Hotels
• Respite centers

Where Do You Put a Thermostatic Mixing Valve?

The thermostatic mixing valve can be placed in the water heater itself. 

Particular plumbing fixtures like showers are where you can also install the thermostatic mixing valve.

How To Install a Thermoplastic Mixing Valve?

• Turn off the main water supply.
• Turn on faucets to empty the remaining water 
• Select perfect installation location
• To install, attach the water supply pipes
• Attach the connection to the valve before fixing it to prevent gasket damages.
• Tighten the attached valve using a wrench
• When the thermostatic mixing valve is attached, open the cold and hot water supply.
• Check the operating valve for leaks

How Long Does it Take to Install Thermostatic Mixing Valve?

A professional plumber can install the thermostatic mixing valve in just a few minutes. 

Why Do Thermostatic Mixing Valve Fails?

Failing operation thermostatic mixing valve usually caused by gumming up debris or scale.

Blocked corrosion and improper fittings are also some of the reasons the valve fails.

What are the Signs Your Thermostatic Mixing Valve has a Problem?

• Improper Water Temperature

Improper changes in water temperature are caused by blocked valve or dislocated valve position.

• Unusual Water Flow

Unusual water flow happens when there is blockage of corrosion or gumming up debris.

• Leak or Grips

Leak or grips is caused by faulty seal or corrosion. 

Consult an expert if you don’t have enough understanding of repairing such valve problems.

How Do You Test a Thermostatic Mixing Valve?

The testing procedure depends on the installed specific type of thermostatic mixing valve.

Below are the main procedures to be followed:

• Measure water temperature 
• Separate the cold water supply to the thermostatic mixing valve
• Standby for at least five seconds
• Examine the water if its temperature is below 46ᵒC 
• The valve perfectly performs if there are no temperature changes
• The valve isn’t working if water temperature changes about 2ᵒC or less

Are the Thermostatic Mixing Valve a Legal Requirement?

The DOH Health Technical Memorandum 04-01 requires a thermostatic mixing valve to prevent diseases, have safe hot and cold water, etc.

How Do You Adjust the Temperature of Thermostatic Mixing Valve?

• Remove the cap on the valves’ top.
• Using the close-fitting spanner, adjust the cap.
• Turn the handle counterclockwise to increase the temperature.
• For decreasing temperature, turn it clockwise.

How Long Should a Thermostatic Mixing Valve Last?

The maintained and well-operating thermostatic mixing valve usually lasts for about 20-30 years.

How Do You Maintain Thermostatic Mixing Valve?

Visual Checking

Check and identify if the valve is appropriately fitted and has excellent accessibility.

Water Temperature

Ensure water temperature between 39°C and 43°C.

Thermostatic Mixing Valve Test

Isolate cold water supply by performing TMV failsafe test.

Clean, Remove and Disinfect

Separate each valve and clean. Remove and disinfect components and filters.

When Should Thermostatic Mixing Valve be Fitted?

Fitting a thermostatic mixing valve as close to 2m as possible is recommended.

Perfectly fitting the valve to the outlet helps reduce the water supply rate in the pipework. 

What is the Maximum Pipe Lenght to a Single Appliance from the Thermostatic Mixing Valve?

Two meters is the recommended pipe length for single applications.

Can a Thermostatic Mixing Valve be Installed Upside Down?

 You can install the thermostatic mixing valve in any position, including upside down or sideways.

How Do I Adjust a Thermostatic Mixing Valve Wattage?

 Using a hex wrench, loosen the locking cap screw. Turn anti-clockwise to increase the temperature and clockwise to decrease. 

What is Thermostatic Mixing Valve Approved?

The specific type of thermostatic mixing valve is approved for healthcare and commercial situations. 

The said valve performs and meets NHS specification D 08 standards.

There are three thermostatic mixing valve types. 

Type 1 –  A mixing valve with extreme temperature stop. 

Type 2 –  A type of thermostatic mixing valve that follows BS EN 1111 and BS EN1287 standards. They also perform with maximum temperature stop.

Type 3 – This valve consists of increased thermal operation as NHS Estates requires.

Can a Thermostatic Mixing Valve Be Set to a Low Temperature?

Yes. Various thermostatic mixing valves can be set to a low temperature, like between 20-46°C. 

Can the Heating System Affect the Performance of Thermostatic Mixing Valve?

Following manufacturers’ instructions on installing heating system prevent improper performance of thermostatic mixing valve.

Failure flow regulator utilization when installing the valve can cause performance issues.

Improper removing flow regulators during vented system installation reduces water flow.

Can a Thermostatic Mixing Valve Also be Used as a Diverting Valve?

There are specific types of thermostatic mixing valves that function as thermostatic diverting valves, like VTD300.

The VTA500 also functions as diverting valve with higher flow capacity.

Conclusion

Considering knowledgeable information above about the thermostatic mixing valve gives you ideas of how crucial it is nowadays. 

You can now choose the best thermostatic mixing valve that suits your applications and maintain its high-quality performance.
