Safeguard your customers and clients, especially children and seniors, by fitting your commercial water heater with a thermostatic mixing valve. 

What is a Thermostatic Mixing Valve?

A thermostatic mixing valve (TMV) is a device that automatically controls the temperature. It mixes the hot and cold water to achieve the desired temperature flowing to sinks, showers, spigots, and other plumbing fixtures. 

The valve maintains a set temperature so you can provide hot water without worrying about scalding or freezing. 

Other names for this valve include tempering valve, anti-scald valve, and shower mixing valve. 

How Do They Work?

  • Using water pressure from the hot water supply line, the valve opens a pathway inside the mixing valve. This allows cold water to enter the mixing chamber.
  • Then, coils immersed in hot water heat the cold water as it passes through. 
  • The actuator closes the valve, so no more cold water enters the mixing chamber once it reaches the desired temperature. This helps avoid burns caused by hot tap water coming out of the faucet when turning on the hot water. 

What are the Benefits of TMVs?

Thermostatic mixing valves are an important part of any hot water system. Since they keep the water temperature comfortable, they help reduce the time spent adjusting for the right water temperature. Other benefits include:

  • Energy consumption reduction by 50%
  • Scalding and burn prevention
  • Comfortable shower and sink water temperatures
  • Help prevent bacteria growth

Thermostatic mixing valves make it easy to maintain safety and comfort. 

Types of Thermostatic Mixing Valves

Temperature mixing valves are available in single-control (SC) and double-control (DC).

Single-control TMVs have one handle or knob to control the hot and cold water together. SC valves are used in residential applications since they can be installed on existing fixtures and piping connections. 

Double-control TMVs have two handles that separately control hot and cold water. DC valves are typically used for commercial applications. 

Commercial Applications for TMVs

Thermostatic mixing valves are specifically used in facilities used by high-risk persons, such as

  • Aged Care Centers
  • Hospitals
  • Hotels
  • Childcare Centers
  • Respite Centers
  • Nursing Homes
  • Schools
  • After School Care
  • Shopping Center Bathrooms

Thermostatic mixing valves accurately mix hot and cold water. They keep precise water temperature and pressure, no matter how inlet temperatures or pressures vary over time.  

With a TMV, you don’t have to worry about adjusting the tap whenever you want more hot water. It keeps the water temperature comfortable for all users.
