Why Thermostatic Mixing Valves are Important

Thermostatic mixing valves are an important component of any domestic water heating system. They play a crucial role in preventing two serious hazards - Legionella and scalding. In this blog post, we'll explain why thermostatic mixing valves are so important and how they work.

What is Legionella?

Legionella is a type of bacteria that can cause a serious respiratory illness called Legionnaires' disease. This bacteria can thrive in warm, stagnant water and is commonly found in domestic water heating systems, such as hot water tanks and boilers.

Why are Thermostatic Mixing Valves Important for Preventing Legionella?

Thermostatic mixing valves are important for preventing Legionella because they help to maintain the temperature of the water in the heating system at a level that is not conducive to the growth of the bacteria. The valve automatically adjusts the temperature of the water in the heating system to ensure that it stays between 60°C and 65°C. This temperature range is high enough to kill Legionella bacteria, but not so high as to pose a risk of scalding.

What is Scalding?

Scalding is a type of burn that is caused by hot water. It can occur when the water temperature in a domestic water heating system is too high, causing the skin to become irritated or burned when it comes into contact with the water.

Why are Thermostatic Mixing Valves Important for Preventing Scalding?

Thermostatic mixing valves are important for preventing scalding because they help to ensure that the water temperature in the heating system is not too high. The valve automatically adjusts the temperature of the water to a safe level, reducing the risk of scalding. This is particularly important for households with young children, elderly people, or those with disabilities, who may be more vulnerable to scalding.

In conclusion, thermostatic mixing valves are an essential component of any domestic water heating system. They help to prevent both Legionella and scalding, ensuring that the water in your heating system is safe and comfortable to use. If you have a domestic water heating system, make sure that you have a thermostatic mixing valve installed to ensure the safety and comfort of your family.
