How to choose a water heater faucet. Electric water heater faucet: reviews. Water heater for tap: features of the device and principle of operation Heated water tap

Today, more and more often you can hear about such a device as a heated water mixer. What kind of device is this, and what is the reason for such a high popularity of the new device among consumers?

What is the new device

People have always strived for greater comfort even in small things, despite the fact that today all houses are equipped with a water supply system and heating, allowing them to receive hot water in any quantity, the turn has come to resolve the issue of maintaining the optimal value.

Heated is a small device that helps maintain a set temperature. A faucet is a device that can be programmed to maintain certain water parameters. Some device options can also be programmed to maintain a certain pressure.

This device is equipped with two regulators. One is used to set the required temperature, and the other is used to set the desired pressure. The sequence of actions is as follows: initially the water temperature is set, then the tap is opened and the pressure is adjusted.

There are currently two options for devices with a thermostat on the market. The first option has a liquid crystal screen that shows data about the set water value. These faucets can operate either from batteries or from mains. Control is usually push-button or touch. There are rare models that can be controlled using a small remote control.

In versions with mechanical models, conventional regulators are presented, having a wide variety of designs in the form of levers, valves or ordinary handles.

The heated water mixer is available separately for the kitchen, bathrooms (shower, sink) and even bidet. Today, many manufacturers are ready to offer consumers separate universal devices that can be used in any room. It is also proposed to use open or closed type devices for installation.

How the device works

The design of a heated mixer is very simple. Each device has a special valve, mixing type. It, in turn, is adjusted using a chuck. The cartridge has a very high sensitivity to the smallest temperature difference, since it is made of bimetallic plates or has wax inside.

Its operating principle is based on the following:

sensing the slightest change in water temperature, the cartridge changes its size (narrows or expands);
temperature settings for water are transferred to the cartridge with a special fastening and adjusting screw;
when suddenly cold water stops flowing into the system, this will become a kind of blockage, since a special limiter is installed on the device that prevents it from heating above 80 degrees;
when the cold water supply is operational again, the process of mixing cold and hot water starts automatically.

Thanks to this device, the risk of getting a burn from getting too hot water on your skin is minimized. This principle of operation of a heated mixer makes the device especially popular in kindergartens, hospitals, and hotels.

Pros and cons of the device

Each household appliance, in addition to a large number of advantages, always has its disadvantages. The mixer, which has a built-in thermostat, did not escape this fate. It is worth noting that these devices have begun to gain widespread popularity among individual consumers, especially among families with small children. Such mixers are an ideal option for maintaining the optimal temperature for installation in apartments or houses where there is variability in pressure in the water supply system, and because of this, when taking water procedures, you have to constantly adjust the water temperature.

So, we can highlight the following advantages of the device:

saving. With this device, the consumption of hot water will be optimal. This is important when water heaters or electric gas boilers, which use electricity in their operation and, accordingly, for heating, are constantly used for heating. In addition, you can set an economical water consumption on the device, which will help save the total volume spent on the adjustment process;
increased security. When taking any water procedures, we can say with complete confidence that overheating of the water is impossible. Agree, each person probably received a significant portion of adrenaline during the adjustment, caused by too hot or, conversely, too cold water. With such a device, all risks are reduced to zero, which is especially important for families with small children;
complete comfort. Considering that the pressure in the water supply system has no effect on the actions of the thermostat, the pressure and temperature will always be constant. Even if some changes occur in the overall system during the operation of the mixer, users do not feel it at all, because the device reacts to any changes instantly and adapts to them within literally two seconds.

Well, all the disadvantages can be reduced to only one thing - the high cost of the device. But those ordinary people who, for example, have a gas water heater for heating water and are constantly faced with the problem of insufficient pressure, which is simply not enough to heat the water, will agree that it is worth paying any money for increased comfort and safety. And, besides, the price, although different from the price of a regular mixer, is still not exorbitant.

How to install the device

Initially, it is worth noting that the installation of a mixer with heated water should be carried out strictly in accordance with its purpose, that is, you should not install a device intended for use in the kitchen in the shower, and vice versa. First of all, the functionality of the device itself will suffer.

Self-installation does not require any special effort. A device with a built-in thermostat differs from a completely ordinary mixer only in the additional thermoelement. Otherwise, the order of actions remains the same:

dismantling old equipment;
installation of a mixer with a thermostat. If you need to connect to an outlet, it is advisable that it be grounded.

the model must be chosen in such a way that it most accurately matches the Russian water supply system to the water supply system of a house or apartment;
Pay attention to the location of the hot and cold water pipes. In the mixer, hot water should enter from the right side, and cold water, on the contrary, from the left. If they are swapped, the thermostat sensor may not start working at all;
in some situations, due to the structural features of the water pipes, cold water may enter the hot pipeline. In order to avoid such mixing of water, pay attention to faucet models equipped with a non-return valve. It prevents mixing of water, and even if there is a complete shutdown of hot or cold water, the flow will be automatically stopped.

When purchasing any mixer, and even more so an expensive device with a thermostat, you should take care in advance about the quality of water entering your house or apartment. Therefore, special filters should be installed in advance at the water inlet into the house. This will help not only extend the life of the faucet with a thermostat, but will also have a positive effect on all the service life of other plumbing fixtures, and in some way will help to save a lot of money, because you won’t have to spend money on repairs or buy new appliances.

If you are concerned about small children who may try to change the settings on your faucet on their own, pay attention to models that have a special locking or child lock feature.

A mixer with a thermostat is currently a very effective device that allows you to normalize the water supply in the water supply system of a house or apartment, and completely eliminate the dependence of uninterrupted operation on the pressure in the system. Such an accessory will be useful for beauty salons and hairdressing salons, since it allows you to completely relieve the hairdresser from constantly adjusting the water, and clients from the unpleasant effect of too hot or, conversely, too cold water in the system.

A long stay without hot water turns a person's life into gray despondency. All people are trying to solve this problem, and everyone does it in their own way. Some install a large boiler, others prefer faucets with a built-in water heater.

The device is almost no different from a conventional mixer. Instantaneous taps are connected to a cold hose. Heating is carried out inside the equipment. Within 3-5 seconds the water will reach a temperature of up to 70 °C. It is worth noting that the instantaneous electric water heater for the tap is made of a special steel alloy that does not corrode and does not form scale.

The device has 3 operating modes:

“Off” - the handle is in the “down” position. There is no water flow, the electrical circuits are de-energized.
“Cold” - the lever is in the “left” position. The power supply is turned off, and ordinary water at room temperature flows from the tap.
“Hot” – the handle is turned to the right. The electrical system is turned on and hot water starts flowing from the tap within a few seconds.

There are models of mixers in which the temperature regulator is located outside the structure. This is convenient - the electronics control all the necessary indicators.

Advantages and disadvantages

The advantages include:

Fast water heating. Hot liquid will be supplied within 5 seconds after switching on.
Excellent technical characteristics of a cold water heater for a tap in the bathroom or kitchen. Liquid temperature - up to 70 °C, good pressure, compact dimensions, local area of use.
Constant temperature. There will be no hesitation towards the appearance of boiling water or, conversely, the flow of too cold liquid.
It will fit perfectly into any interior and will never spoil the appearance of the room.

A flow-through heater that fits onto a faucet has almost no drawbacks. We can only note the high energy consumption - 3 kW per hour. Another drawback is the low flow capacity (up to 6 liters per minute). However, this indicator is quite enough to fill the bathtub or wash the dishes in the kitchen.

Review of Chinese-made faucets with heating function

"Corraveni"	The valve is made of ceramics, the surface finish is made of chrome-plated steel.	There is a self-controlled water temperature system.	60	3	4 200

Before purchasing these devices, you need to pay attention to the power consumption. This indicator should be minimal, since the lower it is, the greater the savings in resources, and therefore money.

During the period when hot water is turned off in the summer in the city or in the country during vacation, you always want to treat yourself to hot water to wash your face or wash the dishes. It is very uncomfortable to do this with cold water.

Of course, you can heat water in a kettle or in a saucepan, or you can forget about these inconveniences. The Aquatherm flow-through heater will supply hot water as soon as you open the tap.

In contact with

Heater device

This appliance looks like a regular kitchen sink faucet. Made from high-quality material, it has a modern design that any housewife will like. The Aquatherm instant water heating faucet completely replaces the kitchen faucet. Its controls are the same - single-lever, turn the knob in one direction - you get cold water, in the other - hot water.

There is a powerful heating element inside. When water passes through it, it has time to heat up to a comfortable temperature. It does not need to be installed next to an existing conventional faucet.
Useful qualities:

power consumption - from 2.5 to 3 kW;
quickly enters operating mode - within 5 seconds from the moment water is supplied;
ease of installation;
smooth temperature control;
has a built-in RCD (Residual Current Device).

The entire mechanism of this heater is designed so that the user does not think about technical issues when using it. I just opened the tap and hot water came out.

The water supply regulator has three positions:

turned off;
cold water supply position without heating;
water supply with heating element turned on.

Connection

Any housewife can cope with this task:
1. First you need to free the device from the packaging and remove the plastic nut from the mounting tube, leaving only the rubber gasket aside.

2. Insert into the hole in the sink and screw from below.

3. You need to connect the cold water supply to the mounting tube from below using a flexible hose, which is sold in any store.

Take into account: It is advisable to use a special tape for sealing threaded connections (fum tape). The water heater comes with detailed instructions in pictures with a connection diagram. It is very difficult to make a mistake in this case.

4. After all connections are connected, you can check them for leaks. Turn on the water without electricity and make sure that there are no obstacles to its flow anywhere.

5. If everything is in order and nothing is dripping anywhere, you can safely plug in the device. The indicator on the protective device located on the electrical wire will immediately light up. To avoid premature failure of the heating element, the mixer contains a special dry running sensor. It turns off the electricity supply if there is no water in the tap.

Advice from the editor: It is worth paying attention to the outlet itself where the water heater will be connected. It must provide for mandatory grounding and a thicker wire - with a cross-section of at least 1.5, and preferably 2.5 square meters. mm.

6. Next, you need to turn the faucet handle to the left, hearing a characteristic click (the heater on relay will work), the water will begin to heat up. This will be indicated by the LED indicator on the mixer. After about 5 seconds the water will be heated to maximum level. Next, the temperature is adjusted by decreasing the water pressure.

The smaller the jet, the hotter the water. In order not to experience discomfort because of this, there is a special attachment on the tap - an aerator. It allows you to create the effect of a large volume of water with low pressure.

Customer reviews indicate that the water heating tap has shown its best performance and remains in many homes as a backup hot water supply system.

Summer interruptions in hot water will not be so relevant if you purchase a faucet with instant water heating. What is a hot water faucet?

Water heater tap design

In essence, it is a water mixer with a high-power electric heating element (heating element) built into it. The water heater faucet consists of a housing, a heater, a thermostat, a water flow sensor and a protection system. Externally, such an instant water heating faucet is no different from an ordinary mixer, if you do not take into account the electrical cord with which it is connected to the electrical network.

Based on the type of control, water heater taps are divided into hydraulic and electronic. The hydraulic valve has power switching regulators. Switching is done manually. Electronic control type thermostats have automatic control over the required water temperature. At the same time, the temperature of the water in the tap is displayed on the electronic display.

Principle of operation

The water heater very quickly (in 10 seconds) brings the water to a temperature of 60 degrees. The water heater tap has a simple operating principle. Tap water, passing through the heating element, instantly heats up to a high temperature. This is the main advantage of the device. After all, electricity is consumed only during water collection, which saves it significantly. The water heater faucet has other advantages.

Differences between cranes according to individual characteristics

Water heater taps differ from each other in such parameters as:

Heating element type , which can be in the form of an open spiral, or a heating element (closed type). The open-type spiral is placed inside plastic tubes. The current passing through the spiral heats the water passing inside the plastic housing. Heating elements are safer to use, since these elements do not come into contact with water;
Device control . It can be mechanical (hydraulic) and electronic. The hydraulic control method only responds to strong water pressure. The electronic control method is also possible with low water pressure; the system itself determines the required power to heat the water;
Principle of operation - pressure and non-pressure. In pressure taps of water heaters, water is constantly under water pressure.

How to use it correctly

The device has a power from 3 to 27 kW. Some consumers complain about the high energy consumption of the faucet water heater. To reduce electricity consumption you need to consider some points:

Calculate your family's hot water needs. If the family is small, then you can install a less powerful water heater;
To save money, you can take a shower rather than a bath.

Since the instant heating faucet is a high-power electrical appliance, when installing it it is necessary to carry out separate electrical wiring and grounding.

Advantages and disadvantages of mixer water heater

A faucet with a water heater has a number of advantages over storage heating devices. The latter do not immediately heat the water, but gradually warm it up, and then spend energy maintaining the desired water temperature. Among other benefits The following should be noted:

Noting the advantages of the device, it is worth pointing out some of its disadvantages . When comparing water heater taps with storage heating systems, it should be noted
following:

Hotter water (60 degrees) is provided only by powerful mixer taps. But, such devices consume a lot of electricity;
If water needs to be heated in large volumes (for a bath), then the energy consumption will also be large;
A faucet with a water heater can operate in trouble-free mode with a stable voltage in the electrical network (without fluctuations);
Such devices cannot be installed in one house, simultaneously at several water collection points.

Thus, after analyzing the pros and cons of water heater taps, we can draw the following conclusion: such devices are more suitable for small needs for hot water, or installed in the summer, when hot water is turned off.

Characteristics and prices of water heater tap models

Water heater taps do not require complex and constant maintenance. But you won’t be able to get a lot of hot water at once using such a device. Typically, a faucet with a water heater has a capacity of 1.8-4 liters per minute. An increase in water flow exceeding these figures leads to a decrease in water temperature.

An instant water heating faucet, which is used only in the summer (at an inlet water temperature of 15-18 degrees), consumes about 3.5 kW, which is quite acceptable. But, for winter operation, such a device will not cope with heating water to high temperatures, since this will require a device with a power of 5-7 kW.

Models with electronic control maintain a constant, specified water temperature at the outlet of the tap (for example, 40 degrees). In this case, the heating temperature is displayed on the electronic display of the device.

Also, the Russian Aquatherm faucet has quite positive reviews.

The price of a water heater tap is quite affordable.

Thus, the price for the most popular models on the Russian market - Aquatherm taps (with a power of 3 kW) - ranges from 5,169 rubles to 6,600 rubles.

Imported models Edisson System 600 (Edisson, UK) with a power of 6 kW for 2670 rubles.

Medium PRO 8 (Timberk, Sweden) at 7.5 kW for 5040 rubles, with heating temperature controller, etc.

Manufacturers of household appliances are constantly working to solve problems facing residents of a big city or countryside village. The lack of hot water in the kitchen or shower causes real suffering to a person spoiled by the conveniences of civilization. An innovative way out of such an uncomfortable situation was an electric running water heater, made in the form of a mixer tap.

Comparison of different heaters

Shutting off the centralized hot water supply, called preventive, has become a common occurrence for city dwellers. For those who live in a country house or in a temporary country house, choosing a convenient and effective way to establish hot water supply has always been relevant.

Gas boiler with heated water supply in a storage tank seems to be the right choice for the cottage. Where there is no gas supply and for a large number of water points, it is more reasonable to install an electric storage water heater of the required volume. Only high-power flow heaters can serve several consumers - a kitchen and a bathroom - at the same time.

A device in the form of a mixer with a built-in instantaneous electric water heater is appropriate where a small amount of hot water flowing from one tap is sufficient. Usually this is a country house. It will also come in handy as a means of surviving the summer periods when the hot water supply is turned off in a sparsely populated city apartment, provided that electricity prices are not critical.

Description of the faucet with flow-through heater

The operating principle of an instantaneous electric water heater is the same for a massive and powerful device mounted on a wall and a compact one in the form of a sink faucet. Water enters the container, where there is a tubular electric heater (TEH), which has the shape of a spiral. In the shortest possible time, the water is heated to a temperature of 60-85⁰ C. The required temperature is maintained for all water coming through the tap; its pressure is regulated by a lever or valve.

The faucet with a built-in electric instantaneous water heater has:

A spout attachment, usually complemented by an aerator (spout divider) with a filter function. In the best examples, it is capable of rotating a full revolution.
Pressure valve or pressure sensor.
Tank for heating running water.
Heating element with ceramic insulation.
Thermocouple to control the heating level.
Mode switch.
Grounding cable for connection to the electrical network.
Electronic RCD system

All this is contained in stainless steel housing or a thermoplastic-based composite and looks quite aesthetically pleasing - like a regular faucet with a slight thickening. Its operation process is also very similar to the operation of a regular faucet.

In the middle position of the lever, no water is supplied and the power is turned off. When turning to the left, cold water flows from the spout, the pressure of which can be adjusted. When you turn to the right, the heating element turns on, which is indicated by the indicator, and heating begins. Its maximum degree occurs within 3-5 seconds. You can regulate the water temperature either using a separate thermostat on the body or simply by turning the lever - with strong pressure, the water heats up less.

Advantages and disadvantages

The main disadvantage of an instantaneous electric water heater is the increased energy consumption. It is not as intense as, for example, a high-power kettle, but models consuming up to 3 kW per hour, with intensive use can lead to significant costs.

Another disadvantage is insufficient resources. It is unreasonable to consider such a device as a long-term and reliable means of providing all hot water needs. The normal operating mode of a faucet with a flow-through heater is to dispense up to 6 liters of water at a temperature of 40-60⁰ C per minute.

The experience of using electric heaters built into the domestic water supply system has revealed problems unique to it. At low pressure, safety sensor can turn off the heating element to avoid overheating, as in the “dry” mode. Users note the negative impact of low-quality water on the flow-through heater, and hence another drawback: the inability to install a high-purity filter in the tap. This should be taken into account when choosing a specific heater model.

But to satisfy less global requests for domestic hot water, this device has a lot of advantages:

In the heater on the tap, the cavity with the heating element is very small and heating of running water occurs instantly.
There are no unpleasant temperature fluctuations. It is even more convenient to regulate the pressure and degree of heating than with some mixers.
Complete safety in operation.
Fast and convenient installation process, accessible to non-professionals.
Compactness and ergonomics of the best models, stylish modern design.

Installation and connection

Installing a faucet with a heater is no different from installing a mixer. The main difference is the cable for connecting the power supply. Designers fastening elements are provided, allowing you to make it invisible and not interfere with the use of the sink or shower.

The combination of water and electricity is deservedly considered deadly, so you should reduce the risk to nothing: buy heaters from certified sellers, carry out installation strictly according to the manufacturer’s instructions. It is important to check that the electrical network complies with the necessary requirements of the flow heater manufacturer when connecting power be sure to ground.

Specifications and price

Manufacturers set the service life of a faucet with a built-in electric water heater from 2 to 5 years, depending on the intensity and operating conditions.
