What is a mixer shower?

Just as the name sounds, a mixer shower is a shower that mixes your hot and cold water together in a valve to reach the right temperature before it comes out of your showerhead. Ideal for both low and high pressure water systems, from standard mains feeds and combination boilers to gravity and pump systems – the only thing a mixer shower won’t do is boost your water pressure.

What is a thermostatic shower mixer?

Just like mechanical mixers, a thermostatic mixer controls both the temperature and water flow of a shower – just from two controls rather than one. What’s more, most modern thermostatic shower mixers have a maximum temperature regulator to protect against accidental scalds and burns.

What is the most important thing about a water heater?

One of the most important elements to designing a highly efficient water heater is having good circulation . Good circulation means that once hot water has been heated, it does not spend time sitting idle waiting for someone to use it before the heat can be transferred. A thermostatic mixing valve enables a more rapid transfer of this heat from one water loop to another without using any additional energy input from an outside pump.

Where is the thermostatic mixing valve installed?

The thermostatic mixing valve is usually installed at the cold-water shutoff, but it will need to be mounted at a right angle to the waterline. The valve will be installed before entering the boiler so that water only enters when it detects colder than setpoint temperatures.

Why is my shower running cold?

Showers are prone to running either too cold or hot. Besides, there’s always the risk of consistent fluctuations in temperature, especially when the water pressure is too low. For instance, when a toilet is flushed somewhere in the house, the tank will get refilled. This causes a dip in the cold water pipes. If someone is taking a bath, they will get scolded. Having a thermostatic shower valve will prevent this.
