  • Nous résolvons un dilemme majeur au moment d’entreprendre des travaux : opter pour un mitigeur de douche monocommande ou au contraire, pour un mitigeur thermostatique ?
  • Chez Noken, nous proposons les deux versions, pour que vous puissiez choisir le design idéal pour votre salle de bains après avoir dressé la liste des avantages et des inconvénients de chacune.

 

When carrying out a refurbishment or fitting a shower, it is possible that doubts arise regarding which is the best equipment choice. For this, the user must consider aspects such as comfort, the technology they want to have, as well as one of the most important features in most homes: the economic aspect.

For the shower, one of the decisions that causes many to have doubts is the bathroom taps selection, since there are different options which are influenced by the previous aspects.

The single lever shower mixer versus the thermostatic taps, which is better for my shower? From Noken Porcelanosa Bathrooms, we want to show the advantages and disadvantages of both, as well as offering different models that are suitable for modern bathrooms with the quality and cutting-edge design that characterises the PORCELANOSA Grupo.

 

The thermostatic shower taps: what they are and what advantages they have

The thermostatic shower tap is a mixer that allows for the sought-after temperature to be selected, which remains constant, even when other taps are opened in the same house. How it works is simple, since only the sought-after temperature has to be selected with the handle, and in no time, the thermostatic cold and hot water cartridge are automatically mixed, reaching the selected temperature very quickly.

Thermostatic shower tap advantages

Among the thermostatic shower taps advantages, we can see:

1. Temperature stability. This greatly determines the user's comfort, since it is nice to be able to reach the sought-after temperature from the beginning, as well as that temperature remaining unchanged throughout the use of the shower without having to be constantly regulating it.

2. Some of our thermostatic taps come with Noken Thermotrust technology. The ledge guarantees the body of the tap will stay cold, avoiding any potential burns.

2. Energy and water saving. Noken cartridges are designed to reach the desired temperature quickly and constantly. In this way, unnecessary water waste is avoided by reducing the reaction time and possible changes in temperature during the shower. Some of Noken's thermostatic taps also feature the Noken Eco-Stop button, which limits the maximum water flow, leading to water savings of up to 50%.

3. Safety. Bathroom safety is crucial for Porcelanosa Bathrooms. Therefore, Noken's thermostatic taps include the SAFE STOP function, which blocks water at 38ºC to guarantee safety, especially for children. This system also cuts off the supply of hot water in case of an interruption to the cold water supply, therefore avoiding the risk of getting burned.

The problem with thermostatic shower taps 

  • They're less intuitive than mixer taps: thermostatic taps have two controls - you can change the flow on one side and the temperature on the other. They're not as common as the former, which could be an issue for some users who aren't as familiar with how they work, such as older people.
  • Thermostatic taps tend to come with a higher price tag than, for example, mixer taps. But it's worth considering they'll use less water in the long term and will last longer, making them a worthwhile investment over time.

  

How does thermostatic taps work? 

They are provided with two remote controls, one used to adjust the flow rate easily and intuitively, and the other one for selecting the desired temperature manually.

One of the other features of these types of taps is their revitalising function. Regarding the concealed thermostatic taps with several water outlets, these ones can be combined with side jets which give the body the refreshing whirlpool treatment, or shower heads with several functions and waterfalls, such as: cascade, rain, jet or nebulizer. Therefore, people can enjoy completely different experiences and a shower focused on sensations.

Advantages of shower mixers

  • One of the main advantages of mixer taps is that they're more like the traditional taps you find in most bathrooms. This means users will know exactly how to use this type of tap.
  • As such, they're very intuitive to use: a simple twist of the lever is all you need to do to choose your preferred flow and temperature, with one gesture. Fast and simple.
  • More hard-wearing: as we've mentioned before, one of the key advantages of mixer taps are the internal ceramic discs that regulate the water flow. These discs are much more hard-wearing and require less maintenance than the parts in dual lever taps for example.
  • Mixer taps usually come with a lower price tag than thermostatic taps.

The problem with shower mixer taps 

Here are some of the drawbacks and other things you need to think about with mixer taps:

  • The flow of water may be affected by pressure variation when installing them. As a result, you may also experience some fluctuations in temperature, and may need to readjust them to your preferred temperature. With thermostatic taps, the system keeps both elements (flow and temperature) constant.
  • You just turn on the tap in the position required for the desired water temperature. This means that if you turn it on in the central position when you just want cold water, you're wasting energy because the boiler will switch on.
  • Higher water consumption: one of the main drawbacks of mixer taps is that most users turn on the tap at full capacity, when 50% of the flow would be more than sufficient for purposes such as hand-washing. The same often happens when using hot water.
  • Less safe: they don't come with smart features such as Noken thermostatic taps' Noken Safe Stop function, a safety feature which stops water getting hotter than 38ºC (especially important for children), thus preventing potential burns.

How mixer taps work 

With mixer taps, the water circuit has cold water on one side and hot on the other. The tap's internal valves open or close (or align for lukewarm water) with different outlets that allow the water to flow depending on whether the lever is turned to one side, to the other, or kept in the central position.

So for example, if the lever is turned on in the central position, water comes through both circuits, resulting in lukewarm water. As you move the position of the lever from one side to the other, you increase the amount of water coming through one circuit, and decrease the other, that way getting water at just the right temperature (colder or warmer).

In terms of turning the water flow on or off, you generally move the lever up to allow the water to flow, or keep it in the off position: the internal discs block the water flow.

 

Frequently asked questions about shower mixers and thermostatic taps 

What are the differences between shower mixers and thermostatic taps?

The main difference lies in how you switch them on: mixer taps have a single lever to regulate the water flow and temperature, whilst thermostatic taps have two.

Are thermostatic taps a worthwhile investment?

It all depends on the user's needs and preferences. They cost more than mixer taps for example, but they save more water and energy, and come with other advantages in terms of user comfort.

How do you clean a thermostatic tap?

First switch off the water, then dismantle the tap and clean the filters in vinegar and water for several hours.

Do thermostatic taps prevent burns?

Yes, Noken's thermostatic taps include the Safe Stop function, which stops the water temperature from getting hotter than 38ºC to ensure safe use and prevent burns.
