How to choose your thermostatic mixer

The thermostatic mixing valve is not complicated in itself. You just have to keep in mind the following criteria to take advantage of its advanced and beneficial use.

#1 - Built-in technologies

The options offered by thermostatic mixing valves are not the same depending on the technologies integrated. They are adapted to the intended use and therefore to the needs of each user. You have the possibility to maintain an unchanged temperature, and therefore a constant comfort, with certain options. No need to adjust the device every time. On the other hand, there are models that allow you to block the temperature on a certain threshold to avoid too hot showers. Suitable for the whole family. Add to this the water saving modes. They distinguish low-end mixers from more efficient models. Then, favor technologies that promote easy handling of the faucet handles.

#2 - Temperature control

We look to adopt a thermostatic mixer for the privilege of effectively adjusting the temperature. It would be a real shame to make the investment while writing off this benefit. Check the setting options, they should match your needs and the comfort of use you expect. The temperature limiter is one of them. You determine in advance the maximum temperature allowed and the setting is adjusted accordingly. The threshold differs for all models. This function should be accessible via an easy-to-operate device. Some people prefer ultra-hot baths to invigorate themselves and need to turn this option off at times.

#3 - Water flow rate

Like the temperature, the water flow rate can be adjusted using a separate system. Again, the thermostatic mixer knows how to be versatile, since not everyone's needs are the same. The device works in the same way as the temperature limiter. In any case, it enhances the comfort of your bathroom. Of course, the presence of this element increases the price.

#4 - Design

More than one loves the style of the thermostatic mixer. That's why the design is a criterion not to be neglected. Go for a model that is elegant and suitable for the bathroom decor. Its material should be in harmony with the other elements of the room. In addition to the material, the finish will determine the durability of the faucet, especially in the face of wear and tear. Look for aesthetics and sturdiness in your choice and choose between a matte, polished, brushed and chrome finish.

Add to this the structure of the mixer. Attention is paid to the type of spout which can be fixed, mobile or cascade. The first is the simplest. With the second one, you gain more freedom during the shower. The last one is innovative although its installation is fixed.

#5 - Power consumption

The thermostatic mixer reduces the water consumption of your bathroom. The presence of the aforementioned flow limiter is a big plus in terms of savings. It takes about 2 liters of water to get the right temperature, and in record time. Limited waste with this revolutionary solution. This is considerable compared to the classic tap which consumes nearly 8 liters, or even more, to have the same result. The reduction in consumption is estimated at about 25 to 30% with the mixer.

Other elements increase the performance of the faucet. This is the case with the aerator, which uses air to reduce the water produced without affecting the flow rate. With this installation, savings increase up to 50%. With C3 models, you can be sure to have a satisfactory and controlled consumption. They meet the standards of the 2012 thermal regulation.

How to install the thermostatic mixing valve?

The level of difficulty of the installation differs from one model to another. It is necessary to inform yourself with the help of the instruction manual delivered by the manufacturer in order not to make a mistake. However, you should know a few things to start understanding how to install this shower and bathtub accessory.

Regardless of the model you are dealing with, the water supply must be shut off before installation. However, there may still be some left in the inlet pipe. Empty it by turning on the faucet if it is a renovation of an old faucet. Then you can remove it to make room for the new mixer. By the way, the new mixer must be compatible with the connection already in place.

If it is not, some equipment should be necessary. Ultimately, adjustments should be made to connect the mixer to the water supply. Normally, there should be a gap of 40 to 150 mm between the wall and the faucet. Adjust the length of the center distance based on the manufacturer's recommendation.

Once all measurements are met and the mixer is straight, attach it to the wall or bathtub, making sure that the joints of the fittings are in place. Otherwise, their watertightness will be affected. Test the faucet (hose and hand shower) and the setting before completing the installation.

The different types of thermostatic mixing valves

Thermostatic mixing valves exist for the shower and the bathtub. There are also those that are distinguished by a flush installation suitable for all types of bathrooms. Each one has advantages and limitations that you should know in order to make the right choice.

Thermostatic shower mixer

The thermostatic shower mixer is equipped with a fixed water outlet. It is installed against the wall, which is the only possible installation for this choice. Moreover, its installation is a real child's play. No need for a professional to do it. Since it is a shower model, it is necessary to provide a direct connection to the hose. The water comes out from this part if there is no spout.

There are several styles of this type of thermostatic valve. Most models have a chrome finish. This is not to say that colored materials are not available. Many like black and brushed silver shower mixers.

Thermostatic bathtub mixer

The installation of the bathtub mixer is multifaceted, but the most convenient technique is to mount it on the wall. There are other options to install the device on the old bathtub faucet if it is a renovation. You can always get a compatible column to install this thermostatic mixer.

Here, you can choose between a classic spout or a cascade spout. The latter is more attractive, but their efficiency is similar. This faucet has a built-in diverter or in the form of a button to turn the water supply into shower mode.

Flush mount thermostatic mixer

This is the most attractive version of the thermostatic mixer. Suitable for both shower and bath, this type of installation is popular in modern or renovated homes. Its flush-mounted installation provides an unparalleled touch of elegance.

Because it is hidden in the wall or bathtub, depending on the installation, only the controls are visible. A less cumbersome system for the bathroom. The concealed thermostatic mixer may or may not have a spout depending on the model.

⚠️ Warning!!!

The thermostatic mixer is not compatible with an instantaneous water heater without a cumulus tank. This is because it needs this element to accelerate the temperature regulation.

Thermostatic mixer or 2-faucet mixer

Thermostatic mixing valve

This faucet has a single control element that combines temperature and flow rate control. This system reduces water consumption and is more suitable for a bathroom. However, the available models are suitable for all types of showers. The thermostatic mixer guarantees a remarkable comfort of use thanks to the stability of the temperature. It includes a mode to limit the temperature so as not to burn users by accident.

Mixer with 2 taps

The two taps here control the production of hot and cold water. The mixer is chosen for a traditional and inexpensive bathroom. The models on the market appeal for their classic and timeless appearance. But it must be said that its temperature control system is in the process of being outdated.

Verdict

The main points of comparison between the thermostatic mixer and the 2-faucet mixer are the savings on the water bill, the design and the safety against injury. The mixer seems to be more interesting on all lines. The various technologies offered have undeniable advantages on the cost of consumption. Inheriting a technique of careful manufacture and well-worked finish, it has a head start on aesthetics. And the materials used avoid burning. However, the mixer remains a preferred choice for kitchen faucets and traditional showers.

Why buy a (good) thermostatic mixing valve?

To save money

The performance of the thermostatic mixing valve in relation to water consumption has been mentioned several times. Thanks to the flow limiter, it takes a very small amount of water to reach the ideal temperature. This is a significant saving in terms of the bill you pay for this expense.

To enjoy a stable temperature

Once the preset is done, there is almost nothing to do before taking a shower. A single button is all it takes to get the right temperature, and it doesn't change throughout the use except when you need to change the flow rate. In any case, the temperature is easily controlled.

To limit the risk of scalding

Mixing valves equipped with a safety device cap the water temperature at a certain limit, set by the user. It's up to you to decide what is best for each member of the family. In addition, manufacturers prefer a cool material that won't heat up when in contact with hot water.

To gain in practicality

The thermostatic mixing valve can be adjusted quickly and easily. It takes only a few seconds to turn on the hot water. Most models merge the temperature and flow control into one button. This makes it even more convenient to use.

For a modern bathroom

The modern aesthetics of the thermostatic mixer are well known. It is its most remarkable asset and the most coveted by users who are currently looking for fashionable accessories to beautify their homes. The materials and colors enhance the decor of the bathroom.

Tips

The location of the device

Think about the possible and expected location before choosing your mixer. Some are wall-mounted and others are recessed. It's up to you to decide, depending on the configuration of your bathroom.

Use the thermostatic mixing valve according to the standards

The sale and manufacture of this accessory are governed by standards relating to temperature, consumption and quality of use in general. These help consumers make their choice insofar as the best products are certified by the NF EN 1111 standard.

Prepare the ground before installation

Before installation, remember to disconnect all the connections from the bathroom water network, especially the water inlet.

Adjust the temperature properly

You need a screwdriver to unscrew the mixer tap and a thermometer to do the operation itself. All devices automatically set the temperature to 38° at first. If needed, you can directly access the temperature adjustment knob inside the faucet to change it at your leisure.

In case of failure, call a professional

A disassembly of the accessory is required for any failure encountered. Some problems can be fixed by yourself, others require the intervention of a professional. In any case, it is preferable to call the latter to have a good diagnosis of the situation.

FAQ

How to replace the cartridge of a thermostatic mixing valve? How does a thermostatic mixing valve work? How to unblock a thermostatic mixing valve?

First of all, find a cartridge that is compatible with your thermostatic mixing valve model. The location of the water outlet is crucial in this case. Turn off the water from the inlet before removing this part with a screwdriver. Detach the handle from the assembly by removing the screw that holds it in place. Use an Allen wrench to separate the cartridge head from the rest. Then install the new cartridge and apply silicone grease to it before adjusting the temperature.

On a thermostatic mixing valve, temperature control is provided by the cartridge and water control is provided by the flow adjuster. Thus, the proper operation of the faucet relies on the efficiency of the cartridge. Manufacturers incorporate a temperature limitation system into their products to maximize safety. In this sense, the maximum temperature that can be set oscillates around 40°C.

The mixer stops working properly in the presence of scale or after a fairly long period of non-use. To solve the problem, turn off the water supply and drain the faucet of any remaining water. Remove the temperature control and all seals. When the faucet head is removed, clean the entire assembly with white vinegar.

The temperature becomes unstable when the water flow is not normal, i.e., too low or too high, the latter being more rare. Another possibility is that there is a leak somewhere in the mixing valve and this creates a malfunction in the hot water supply. When the water produced is dirty, consider cleaning the mixer, as it may be a victim of limescale deposits.
