Buyer Guide to Choose the Best thermostatic Mixers

The product is equipped with a thermostatic valve that mixes cold and hot water continuously, maintaining constant flow and temperature.

Of course, there are also safety systems, such as interruption of the supply if there is a lack of cold water, avoiding burns to the unsuspecting user, intent on taking a shower.

Quality 

Compare prices and performances of the various thermostatic mixers and you will notice the significant difference between the various models.

There are, however, products that are characterized by the excellent relationship between the overall quality and the not excessive price, as you can see among those that we recommend below.

All the mixers, however, must guarantee basic performance and, mainly, they must ensure that the temperature of the jet remains unchanged for the duration of the shower, even if other taps are opened at the same time.

In this way, there will be no pressure change and none of those annoying peaks of cold or hot water that risk causing burns and make the shower less pleasant.

This important advantage is ensured by the thermostatic valve which reacts immediately to any variation, immediately regulating the mixture. It is ideal if there are children or elderly people in the house.

It is the consumer who regulates the temperature, setting it at the desired level which can, of course, be modified as desired. Furthermore, if the flow is closed for a few moments, for example to make the shampoo, by reopening the water the temperature will be identical and it will not be necessary to wait or adjust it again.

Another feature that many users find useful is the ability to set a temperature lock, generally at 38 ° C, which, once activated, prevents it from being changed. This is an important precaution for children who want to shower or bathe alone and who may inadvertently raise it. In this way, they are safer and parents more peaceful.

Water-Saving and Safety

The possibility of having the desired temperature very early and not having to change it during the shower avoids unnecessarily wasting water before finding the right mixture and, in this way, there is less consumption and, therefore, savings in utility bills and for the environment.

Furthermore, thermostatic mixers can be equipped with other functions. For example, the best brand models are characterized by a particularly valuable finish that offers three advantages: firstly, greater resistance to wear.

Which makes these products destined to last for years and years; secondly, a channel of cold water placed under the external coating ensures that this never exceeds the water temperature thus avoiding getting burnt by touching the mixer.

Finally, the special chrome plating present on some models, being repellent to dirt, scratches and oxidation, guarantees a brilliant appearance that remains unchanged over time.

Flaps and Assembly

Sometimes, when you have wet or soapy hands, it may not be easy to grasp the end of the mixer to adjust the temperature. Some models, to allow a more comfortable and safe grip, have very useful lugs that solve the problem.

As regards assembly, thermostatic mixers should not be particularly difficult to install and a minimum of practicality is enough to be able to do it even without the intervention of a technician. It is better to check that all the accessories are included in the supply, in particular, the eccentric (adapters) with gasket.

How to Use a Thermostatic Mixer?

What is a thermostatic mixer first? It is basically a tap capable of delivering water at a constant temperature.

Where to Mount It

It can be installed in any room of your home and there are models both indoors and outdoors. The most elegant, with chromed finishes and with a modern and design cut, are suitable for environments such as the bathroom or the kitchen.

While those more spartan and able to resist atmospheric agents are more suitable for a garden, a terrace or however an external environment.

Savings in Utility Bills

Even if their cost is higher than that of a simple tap, before considering them excessively expensive, one must take into account a very important factor: saving on the water bill.

Often, when showering or washing dishes, one tries desperately to position the tap so that the water is at the right temperature, not too hot or too cold, so as not to burn or freeze in winter. This procedure, however, takes time, during which the water escapes copiously, representing an avoidable waste.

The mixer manages to save time and money thanks to its ability to independently regulate the temperature. How do you do it?

Mounting

If you are convinced, and you have already purchased your mixer, it must be assembled. If you are not an expert, or not accustomed to doing it yourself, the best option would be to contact a professional in the sector.

Even if it would mean spending more money. If you have already carried out such operations, remember that you will need: silicone, Teflon tape, wrench and screwdriver.

Eccentric Fittings

Once the pre-existing tap has been dismantled you will have to use the eccentric fittings, included in the package or sold separately, to be able to equalize the hot and cold water pipe.

To arrange them perfectly, cover the thread with Teflon tape, useful to avoid water leaks, and hook them with the wrench, taking care not to overtighten.

Place the Mixer

Now, insert the mixer and try to position it perfectly horizontally, using a level if you have one. You just have to screw the mixer and make the first test.

If it works correctly you should be able to set the temperature with one of the two knobs, while with the other one open and close the water jet.

Seal with Silicone

If you do not experience any problems and do not notice any leaks coming from the pipes, you can add silicone to seal and stop the mixer on the wall.

Before carrying out this procedure, carefully dry the surface and make sure there is no drop of water.
