Thermostatic mixing valves are used throughout most facilities. They can be found where there are faucets, showers, and other point-of-use locations where people come into contact with water at your facility. Why are thermostatic mixing valves present in areas where water comes into contact with people? For one very important reason: to protect your patrons from scalding water.
In this article, you will learn exactly how thermostatic mixing valves work, why they are needed, where they are installed, when they need to be replaced, and more in a Q&A format. After the Q&A’s, you can learn more about the valves we carry and the most popular heating equipment manufacturers we work with.
Thermostatic Mixing Valve Q&A
Q: What does a Thermostatic Mixing Valve do?
A: A thermostatic mixing valve blends hot and cold water to ensure safe temperature water at the outlet.
Q: Why do we need Thermostatic Mixing Valves?
A: Thermostatic mixing valves are used to accurately mix hot and cold water before it comes into contact with people. This stops scalding water from coming out of the shower or faucet, which can be dangerous.
Q: Where are thermostatic mixing valves used?
A: In commercial facilities, you are likely to find two different types of thermostatic mixing valves:
- 1. Point-of-Use Valves: Also called Single Thermostatic Mixing Valves. These can be found at the faucet or showerhead.
- 2. Group Control or Master Thermostatic Mixing Valves. These valves control a group of point-of-use fixtures, like a shower room with 10 showerheads.
Q: When does a thermostatic mixing valve need to be replaced?
A: You will know that a thermostatic mixing valve is going bad when the water temperate from the point-of-use starts to fluctuate. A proper functioning mixing valve will maintain a constant temperature.
Q: What is the difference between a tempering valve and a thermostatic mixing valve?
A: They are very similar but essentially, a thermostatic mixing valve is exact, and a tempering valve only tempers the water, so with it, you will get fluctuation. It is acceptable to use a tempering valve in areas where direct contact with skin will not occur, like for water used in laundry machines, where fluctuation is alright.
Q: When do you need to pair a temperature gauge with a thermostatic mixing valve?
A: A temperature gauge is only required with a mixing valve when it is being used in conjunction with eye safety fixtures.
Q: Why are thermostatic mixing valves the preferred water temperature controlling devices for large commercial facilities?
A: Thermostatic mixing valves are the preferred water temperature controlling devices in commercial buildings like health care facilities because they limit maximum outlet temperature even when the pressure or flow differs due to the outlet’s location or distance from the water source.
