Comparison Grohe Tempesta Cosmopolitan System 250 Cube 26694000 vs Grohe Vitalio Start System 250 Cube 26696000

The number of settings provided in the hand shower for top shower (see "Complete set").

If you have several settings, change the jet features and, accordingly, adjust the shower to the user’s wishes. For example, one watering can provide «rain» (ordinary drops of medium size), «waterfall» (stream in the form of water wall) and «stream» (continuous jet under high pressure); there are other modes, their specific set for each model is worth specifying separately. In any case, the more settings - the wider the choice of the user, but the more expensive and more difficult the watering can be on the background of models with one mode upper shower.

Water consumption during operation of the upper shower (cf. «Equipment»). Indicates the amount of water passing through the watering can with the tap fully open and the water pressure 3 bar (standard household water pressure).

The higher the bandwidth of the watering can be - the more powerful and intense the shower becomes. On the other hand, high water consumption is undesirable if you want to save water - for example, if you have meters installed or if water is supplied from a boiler with a small volume. In addition, it is worth remembering that the watering can have different settings and features of water supply. So, by selecting the lake with the right parameters, you can get a nice and effective top shower even when low water flow. Actually, a low value in this case is considered to be up to 10 l /min; the average is 10 - 20 l/min, and in the most productive watering can be up to 30 l/min and even more.

The number of jet settings provided in the complete manual or hygienic watering can (see "Complete set"). However, hygienic leukemias are usually made single-mode - this is quite enough considering the application. But in conventional manual waterjets can be several, which allows you to change the characteristics of the jet at the request of the user - for example, instead of the usual thin jets, turn on a hard jet from a single large nozzle or a solid «soft» Flow from water filled with air bubbles. The specific set of settings can be different, it is worth to refine separately. However, in any case, the more options - the wider the choice of the user and the more complicated and more expensive the watering box itself.

The throughput capacity of a manual shower watering agent, in other words, the amount of water it gives out per minute when the faucets are fully open. Since the capacity is not only related to the design of the watering box, but also to the pressure in the water supply, it is customary to specify an average value - at a standard pressure of 3 bar.

The higher this parameter - the more intense the impact on the body can have a shower. At the same time, high water consumption can become a problem when there are water meters or when there are limited supplies - for example, if hot water is supplied by a boiler. Also note that , low throughput can be compensated by certain jet settings.

The length of hose for the shower head be supplied with a shower system of one type or another (see above). In most modern models, this parameter is about 140 - 160 cm - it is enough that even a tall man could easily rinse completely, from the top. In addition, some hoses can stretch 20-30% of their original length. So in practice, it is worth paying attention to the length of the hose except in special cases - for example, if the system is bought for a very spacious bathroom and you need a shower with an increased «radius of action».

— Double lever. Classic version with two separate swivel taps, one of which is responsible for hot water, the second - for cold. The advantages of twin-valve mixers are simplicity, reliability and accuracy of temperature setting. On the other hand, they are less easy to adjust than single-piece.

— Single lever (joystick). One lever capable of moving in two planes is responsible for all adjustments in such mixers. When moving in one plane (usually right-left) the temperature is adjusted in the other (up-down or from itself - on itself) - pressure. In addition, such a mixer allows you to «remember» a certain variant of temperature - it is enough to close the water without moving the lever in another plane. But tuning accuracy in such models may be lower than in two-valve.

— Thermostatic. Mixers equipped with a thermostat - a mechanism for maintaining a constant temperature of water at the outlet. This is the most advanced and convenient option, but expensive. It is enough for the user to choose the desired temperature (in degrees) and pressure, and the thermostat will automatically adjust the proportion of hot and cold water. There are models both classic with swivel regulators and thermostatic with button (read more about the button below).

— Buttoning on. Type of mixers con...trolled by pressing a button. This way a certain amount of water is supplied, which helps to save money.

— Single-valve. A variety found in hygiene kits (cf. «Type»). In fact, such a device is not a mixer, but simply a tap designed only to open and close the water. The idea behind this design is that only cold water is often used for hygienic showers, for which one valve is sufficient.

The diverter is a device by which the flow of water can be switched between individual components of the system - for example, the spill (if it is present) and the shower box, or between the watering can and the upper shower. The design of such a device and the way it is controlled can be different; in modern shower systems, you can find, inter alia, such options:

— Levery. Diverters are in the form of a swivel lever; most often this lever is driven directly by a valve that switches the water flow, but in advanced models there is also an electronic working principle. In any case, lever switches are most popular in modern shower systems: they are very convenient and intuitive to operate, and mechanical diverters of this type are also very simple and inexpensive.

— Push-button. Diverters of this type have the form of a button; but its specific design depends on the features of a particular system. In relatively simple mechanical models (such a majority) the button is also made mechanical, and to switch to the shower watering can be pulled up. And switching to the other side - from the watering box to the drain or the top shower - can often be carried out not only manually, but also automatically, when the water is turned off. Due to this function, the next time the tap opens, the water begins to flow not through the shower hose, which may be in the wrong place, but through the spout or the upper shower, which usually does not cause problems. In some models..., the autoswitch can also be locked at the user’s request (usually by turning the button at the top).
In turn, in advanced electronic devices, such a diverter is made in the form of an electric button, which closes the contacts that control the valve.

— Bend. Rather rare and specific variant: the role of a lever controlling the flow of water, performed directly draining, to the base of which a shower hose is connected. This control usually works as follows: as long as the spout is perpendicular to the mixer housing (that is, directed towards the bath or pan) the water flows through it; and to switch to the shower, the pour is rotated under the mixer. Such devices look interesting, and in use convenient. On the other hand, they are quite complex and expensive, and the flow itself, for a number of reasons, is usually made quite short. Therefore, this option is not available.

— Rotate the drain + push button. The combination in one system of two divers described above. As a rule, the flush turns are responsible for switching the water between the flush and the «shower part», and the button switches between the shower hose and the upper shower. Due to its complexity and cost, this combination is extremely rare.
