A TMV (Thermostatic Mixing Valve) is a type of valve designed to control and regulate the temperature of water in a plumbing system. It is commonly used in showers, baths, and other fixtures where maintaining a safe and comfortable water temperature is essential.
The TMV valve blends hot and cold water together to achieve a desired mixed temperature. It typically consists of an inlet for hot water, an inlet for cold water, and an outlet for the blended water.

What are the top reasons for using a TMV valve in your shower?
-
Scalding prevention: One of the primary reasons to install a TMV valve is to prevent scalding accidents. The valve helps maintain a consistent and safe water temperature by blending hot and cold water together before it reaches the showerhead. This ensures that the water temperature remains within a safe range and reduces the risk of scalding, particularly in households with young children, elderly individuals, or people with reduced mobility.
- Temperature control: TMV valves provide precise control over the water temperature, allowing you to set and maintain your preferred temperature for the shower. Fluctuations in the water supply won't affect the temperature.
-
Enhanced comfort: With a TMV valve, you can enjoy a more comfortable shower experience. The valve maintains a stable water temperature, eliminating sudden temperature changes caused by water pressure fluctuations or other water sources in the house being used simultaneously.
-
Water and energy efficiency: TMV valves promote water and energy efficiency by reducing the need for hot water adjustments. They minimize water wastage while waiting for the water to reach the desired temperature, leading to lower water bills and decreased energy consumption.
-
Compliance with regulations: Installing TMV valves may be required by law or recommended for safety in certain buildings such as healthcare facilities, schools, and public buildings.
-
Protection against temperature fluctuations: TMV valves act as a buffer against sudden changes in water temperature caused by other water users in the building. This ensures a consistent and comfortable shower experience without unexpected hot or cold shocks.
