Criteria for choosing a new water heater for the kitchen. Inexpensive household water heaters: salvation from shutdown

Centralized hot water supply is gradually losing its relevance due to frequent interruptions, Bad quality services and high costs. More and more people are thinking about buying a water heater for the kitchen for washing dishes. To always use water comfortable temperature, choose a high-quality, practical and economical heater option for your kitchen. To do this, it is enough to familiarize yourself with their main varieties and choose the appropriate model.

If we are talking about a kitchen where water consumption is not very large, an instantaneous water heater is right choice. The principle of operation of an electric instantaneous water heater for the kitchen is very simple. He looks like geyser: a small stream of water comes into contact with a heated heating element and very quickly heats up to the desired temperature.

Washing dishes is much more convenient with a water heater

Flow heaters are of two types:

• non-pressure;
• pressure.

Non-pressure kitchen water heater

The first type is a small container located above the level of the tap. To understand what design you are dealing with, imagine the simplest washstand that everyone has in the country. A container with water and a hole at the bottom. Now add a cauldron to it. Something like this on the fingers can be described without pressurized water heater for the kitchen and suggest what kind of pressure you should expect.

Elementary design of the heater

The valve that restricts the flow of water into the container is similar to the one that can be found in the toilet bowl. The position of the float depends on the water level in the tank. When the level drops, the float drops and thereby opens the valve. Water begins to flow into the heater. When its level reaches the desired level, the float rises and shuts off the water supply. This simple design protects the system from overflow.

In fairness, it should be noted that with a small pressure, water from such a heater flows well. This is because the faucet that comes with the flow boiler is equipped with a special diffuser. Water, passing through very small holes, creates a good pressure for comfortable use.

Attention! Such small holes are often clogged with fine particles of sand, rust and other impurities that are found in abundance in tap water. Therefore, you need to be prepared for the regular replacement of this part of the heater.

Pressureless hot water option

The advantages of this type of heater:

• water can be poured independently (convenient for giving);
• the ability to replace the heating element in the event of a breakdown;
• not high price;
• compactness.

Disadvantages of non-pressure water heaters:

• relatively low efficiency at high energy consumption;
• uncomfortable placement;
• lack of an insulating layer, like a storage heater;
• dirty water will quickly disable the device.

Pressure flow water heater

Much more practical option is considered a pressure instantaneous kitchen water heater. He works on similar principle. The difference lies in the fact that water is constantly supplied under pressure. This water heater has a thermostat to control the temperature. You can change the power of the heating element itself or influence the water supply. It is logical that with less pressure, water heats up better.

• faucet heater;
• stand-alone flow type.

The flowing water heater on the faucet for the kitchen attracts with its compactness and appearance. It would seem, why all these complex structures, large tanks and labyrinths of pipes, if the solution could be so simple - a heater built directly into the faucet.

Looks like the interior of the kitchen of the future

But here not everything is as obvious as it might seem at first glance. The faucet-water heater is a slightly modified mixer, in the body of which a powerful electric heating element and several microcircuits are placed. Change of parameters of a heater is carried out by the lever of the mixer.

The water heater tap is plugged into a regular outlet, the power of the device is on average 3 kW. Since with such power it is impossible to provide a large volume hot water per minute, the water heater produces only 3-4 liters, depending on the initial water temperature.

Instantaneous water heaters for the kitchen can also be in the form of a separate electrical appliance connected to the water supply and mixer with flexible hoses. This type of boilers is presented on the market more widely. You can choose your option required power, size, configuration and volume.

So small that it fits easily in a closet

The advantages of this type of heating devices:

• good pressure;
• full control of temperature and power consumption;
• compactness.

Disadvantages of pressure water heaters:

• high costs electricity;
• high cost of the device;
• installation difficulties.

Which storage boiler is appropriate in the kitchen

A bulk water heater for the kitchen works differently. It is a tank with thick walls, inside of which there is an electric heater. The boiler is also equipped with a thermostat to control the water temperature. Such a heater is attached to the wall, since the supply is from below, and the hot water exits from above. In the kitchen, the option of placing under the sink is common.

Boiler concealed option

The principle of operation of a bulk type boiler is to gradually heat the water entering the tank. When the water heats up to the set temperature, the sensor will automatically turn off the heating element. When it cools down or is consumed, the sensor will turn on the heater. So inside storage water heater there is always a supply of hot water of the same temperature, which is very convenient.

But in the kitchen it makes no sense to install a large volume boiler. The consumption of water for washing dishes is usually small. Constantly heating 80-100 liters of hot water in order to wash a couple of dishes is not economical in terms of energy consumption. Yes, and such a unit will take up a lot of space. For the kitchen, small bulk boilers with a volume of 6-10 liters are best suited, which do not consume much electricity and have a compact size.

Looks neat

The main advantage of a storage water heater for the kitchen is its power. As a rule, these devices can be connected to a regular household outlet - they do not consume a large amount of electricity, which means that the load on the electrical wiring will be acceptable. But nevertheless, before buying a high-power boiler - from 5 kW, consult a qualified electrician if your wiring can withstand such a device.

What to consider when choosing

If you plan to buy a heater to use it exclusively during preventive maintenance of the central hot water supply, it does not make sense to spend money on an expensive model. AT summer period you will completely manage with a flowing boiler of small power with a small declared volume of water supply.

Choosing a heater is not easy.

If you need to use the boiler in the kitchen all year round, consider storage models of small volume - up to 15 liters. Because tap water is winter time very cold (about 5 degrees), the instantaneous water heater may simply not be able to cope with such a temperature difference.

How to choose the volume

Boiler power is the main characteristic. And it's not just about the heating rate and energy efficiency class. The importance of this issue lies in the fact that in most apartment buildings it is not possible to install high-capacity water heaters due to poor electrical wiring. You can independently connect devices up to 5 kW, then you will have to connect to the shield with a separate thick wire or even use a three-phase network.

The most low-power are storage boilers. You can find small models starting from 0.8 kW. Tap heaters, flow boilers consume approximately 7 kW. Electrical appliances of higher power do not need to be installed in the kitchen. But if hot water is consumed not only for washing dishes, but also for taking a shower, they will be appropriate.

The dependence of the water heating time on the power of the heating element

Since an electric water heater combines 2 potentially dangerous things: water and electricity, everything must be considered when choosing safe operation. Good boiler equipped with a residual current device (RCD) in case of power outages. Protection against overheating of water and automatic shutdown in case of “dry” switching on should be installed. And don't forget grounding.

How to install a water heater yourself

Installation of the water heater should be carried out by an experienced craftsman who understands plumbing and electrics. Since there are several types of water heaters, they need to be installed in different ways. The installation process has common features, but there are also features that are inherent in each type of device.

Crane model

Installing a water heater built into the mixer is quite simple. Since the power of the device is low, on average about 3 kW, it can be connected to a conventional outlet. Water heater installation algorithm flow type with faucet:

1. First you need to assemble the water heater itself. Connect the main mechanism to the faucet spout, popularly called the "gander". The main unit of the device does not need any intervention, it is sold fully assembled and ready for installation.

The device is sold unassembled.

1. The next step is to install the water heater on the sink. For this, it provides special hole. For sealing, a set of rubber seals is sold together with the heater. Install the connecting insert into the main unit.
2. Another sealing ring must be installed in the hole on the sink. Then place the faucet with the connecting insert there.

1. A nut is screwed on from below for stability and reliability.
2. Connect the faucet to the cold water supply. Use sealant. Make sure there is no leakage: turn on the water without connecting the faucet to electricity.
3. If the installation is successful, you can plug the water heater into the outlet.

Important! Since the wire in the heater kit is usually not too long (about 1 m), care must be taken in advance to have a suitable outlet within reach.

There is nothing complicated about it, the flowing electric water heater for the kitchen with a built-in faucet is ready for use.

Accumulative under the sink

It is most convenient if the boiler in the kitchen is located under the sink. It is practical and not conspicuous. But installing any storage boiler in this way will not work. You need to make sure that the selected model is connected to the water supply from above. To install a water heater for the kitchen under the sink in accordance with all the rules, you will have to work a little.

1. Prepare the boiler. There are 2 fittings on top of the water heater, as a rule, they are painted red and blue colors. It's easy to guess what they mean. It is advisable to additionally install a so-called non-return valve on the supply connection (blue). It will protect the device from the reverse movement of water, rupture of the tank if the heating element breaks, and will also make it possible to drain the water if necessary.

1. Then install stop valves for water inlet and outlet. The valve for hot water (outlet) is installed separately, for cold water - together with a check valve.

1. Connect the boiler to the water supply. Install tees on water pipes. The diameter of the pipes used can be found in the technical specifications specific model. Usually pipes 16-20 mm are used. Be sure to use sealant. It is important not only to tighten the threads well, but also not to overtighten them so as not to damage the gasket.

1. The non-return valve that you installed before the water enters the boiler has a hole from which water will drip. Install a special drip or siphon so that the water flows in the right direction.
2. The electrical part consists in properly grounding the electrical appliance and connecting it to electricity.
3. Before turning on the water heater, fill it with water. Only then can you start using hot water in the kitchen.

Installation completed

Pressure flow water heater

A flowing pressure water heater that is installed on the wall is not so easy to mount. First of all, this is due to increased safety requirements. It's no joke, an electrical appliance with a power of 6-7 kW, from which water flows so easily. Water and electricity are a dangerous combination. You can describe the connection process step by step like this:

1. Rate your electricity meter. It should indicate the maximum current limit. To convert this value into power, multiply the number in Amperes by the mains voltage - 220V. So you get the total power of electrical appliances that your meter can withstand. For example, for a 32 ampere meter, this will be 7kW. Do not forget about other devices that also consume a lot.

Power information must be indicated on the device

1. Choose a water heater based on these data. To connect the heater, you need to allocate a separate three-core (phase, zero, ground) cable of sufficient cross-sectional area. Ideally, this should be handled by an electrician. Connect the cable to the outlet where the device will be connected.
2. Install wall mounts, they may come with the heater, but most often they need to be purchased separately.
3. The next step is to connect the device to the water supply. It is not difficult to do this, the main thing is to achieve complete sealing so that all connections are absolutely dry. Connect cold water to the "inlet" of the water heater. "Exit" connect with the mixer.

1. Install additional shut-off valves (valve) in front of the water heater so that the water supply can be shut off.

Top 5 Most Popular Kitchen Water Heaters

It is very difficult to understand all the variety of offers on the water heater market. Eyes run up from the range. But according to the experience and positive feedback of many buyers, we can distinguish the top five kitchen heaters that combine high quality and reasonable price.

FerroliHotDog HD 5.5

The Italian concern Ferroli has long been known in the European market. Boiler FerroliHotDog HD 5.5 is in great demand among buyers. This is a water heater accumulative type, but outwardly it does not look at all like its bulky counterparts. Ferroli is equipped with a tank of only 5.5 liters. It looks very neat, because its dimensions are simply miniature: 225 * 280 * 380 mm.

Attracts buyers and stylish design. The shape of the boiler resembles an egg. There are bright blue inserts. The body is made of cold rolled steel. Switching on and off is done with a simple push of a button. The LED on the case will show if the device is on. You need to install it on the wall, it does not matter if it is above or below the level of the crane.

The inner surface of the tank is coated with a special enamel to protect and prolong the service life. To prevent the tank from becoming unusable under the influence of corrosion, a magnesium anode is placed inside, which, due to its electrochemical potential, pulls over all the negative manifestations of galvanic couple corrosion that occurs inside the boiler tank.

In order for the water in the heater to maintain its temperature longer, the inner tank is protected by polyurethane foam insulation. This material holds heat very well, which is not only convenient, but also economical. The heater, which is used in the production of FerroliHotDog HD 5.5, is made of steel. Power - 800 watts. It takes an average of 23 minutes to fully heat up the boiler, and working temperature, which this instantaneous water heater for the kitchen can easily cope with - 75 0.

The cost of such a compact, but very practical unit fluctuates around $ 75.

The Swedish brand ELECTROLUX offers customers a good option for a non-pressure water heater ELECTROLUX Smartfix 2.0 6.5 TS. Having more than modest dimensions, this heater copes well with its function, which is why it has earned such popularity. The dimensions of the device are 270 * 135 * 100 mm, weight - 1.3 kg. Such lightweight design can be installed on any wall. The supply of communications to the ELECTROLUX water heater is carried out from below.

The device automatically turns on when water begins to flow through it.

The rated power of the water heater is 6.5 kW. This is a fairly large indicator, ELECTROLUX Smartfix 2.0 6.5 TS should not be plugged into a regular outlet for reasons fire safety. For even greater safety, manufacturers have equipped the device with overheating protection.

The performance that this model from ELECTROLUX boasts is 3.7 l / min. This is enough for quite comfortable washing dishes. You can buy ELECTROLUX Smartfix 2.0 6.5 TS for $70.

Flowing electric water heaters for the kitchen of Israeli production AtmorIn-Line can be built-in and do not spoil the appearance of the kitchen at all. Compact device white color with an elegant pattern and company logo - this "baby" is one of the leaders among kitchen boilers. 185 * 300 * 110 mm - these are the dimensions of this water heater.

The power of the heating element is 5 kW. The minimum operating pressure is 0.6 bar, the maximum allowable pressure is 5 bar. Performance flow boiler depends on the time of year. Since the water in the tap is much warmer in summer than in winter, average performance also has different meanings. In winter, you can count on 3 liters of hot water per minute with an average pressure, in summer - up to 4.

To protect against "dry switching" a sensor is installed. The heater does not turn on until the water pressure reaches 0.6 bar. There is also an automatic shutdown system in case of possible overheating. The price for AtmorIn-Line 5 kW is from $115.

Heated faucet from Delimano

The Delimano brand is now on the buzz. The kitchen tap water heater is one of his most popular products. First of all, the revolutionary design is striking. The heater looks like a simple mixer. The built-in heater provides instant heating of water. The body is made of plastic and metal.

Stylish modern design- one of the main advantages of this heater. You can control it with a lever on the body, adjusting the pressure and temperature of the water. The size of the device is 125 * 70 mm, the weight is a little more than 700 g. The device is simply plugged into an outlet, and it is connected to the water supply in the same way as a conventional mixer.

Water heater power - 3 kW. It sounds more than pleasant, because the manufacturer claims that this miracle device spends no more than five seconds on heating water. Working pressure - from 0.4 to 6 bar. The first indicator has great importance for economical consumers of electricity and water. Such a low value of the minimum operating pressure allows you to use hot water, barely opening the valve.

For such an instant water heater, you will have to pay about $ 65.

Another storage water heater that will fit even on small kitchen— TesyBiLightCompact GCU 1015 L52 RC. This is a 10 liter boiler. The dimensions of this model are 399 * 377 * 247 mm, the weight of the device is 6.6 kg.

Considering all varieties kitchen water heaters Having familiarized yourself with their characteristics, advantages and disadvantages, it becomes easier to choose the right model. The choice of a boiler always remains with the buyer, but it is better to entrust the installation to a professional. This will help to avoid unpleasant surprises during operation.

A small water heater installed under the sink in the kitchen or bathroom saves space in small spaces. It is hard to imagine that back in the last century, people living in private homes had to manually heat water in order to wash dishes and solve elementary household tasks. Today, the ability to install a water heater under the sink allows you to make life much more comfortable. Such equipment is installed not only in private houses, where there is no hot water supply at all, but also in comfortable apartments, where there are failures in the water supply.

There are several reasons for installing such equipment, and the choice largely depends on them. suitable model.

1. In case of complete lack of hot water supply. In such rooms, not only a water heater under the sink can be installed small size, but also a large volume storage boiler for the bath.
2. For use during the summer season. Every year, in many cities, hot water is scheduled to be turned off in the summer for diagnostics and repair of water mains. In order not to experience difficulties with constant heating of water for domestic needs, many install a similar type of equipment in their apartments.
3. In case of sudden emergency shutdown hot water when the house can be held construction works or pipe replacement. In this case, it is recommended to use devices of small volume. A ten-liter water heater can easily fit both under the sink and on the wall and will not cause any trouble. In addition, it is worth noting that most often they are produced in classic colors, which will not spoil the aesthetic appearance of the space.

Types of water heaters for installation under the sink

In fact, in order to make a choice that you will not have to regret in the future, you need to decide for what purpose the water heater will be used. This largely depends on the type of device purchased. Each water heater consists of two branch pipes and heating element which turns cold water into hot water.

Is more popular electrical equipment, insofar as gas-burners in many rooms it is impossible to install due to design features.

Depending on the principles of operation, electric water heaters are divided into two types:

• flowing;
• cumulative.

Flowing

In the flow device, water, passing through a powerful heating element, immediately enters the tap. Accordingly, the power of the heating element in such a device is high and amounts to 3 - 27 kW. Not every wiring is able to withstand such a load: in old houses, the machine cuts down even at 5 kW. New and serviceable electrical networks can withstand a device rated for no more than 12 kW. More powerful equipment requires three-phase connection.

Flow type water heater

Cumulative

The accumulative variant, unlike the flow variant, has small capacity for storing water supplies, so they take up more space under the sink, and their cost is higher. But they outperform the flow ones in terms of performance, since the water in the storage tank is first heated for some time, and only then it is fed to the tap.

In addition, the power of their heating element is lower. For example, in the capacitive devices of the leading manufacturers Thermex and Gorenje, 15 liters are equipped with heating elements, the rated power of which is from 1.5 to 2.5 kW. Accordingly, such equipment is suitable for connection to a conventional power supply.

If the flow device heats the entire flow of water at once and, depending on the power of the heating element, can heat up to 30-40 degrees (depending on the season) from 1.8 to 4 liters, then storage boiler it will take some time. In the case of water consumption, cold water enters the tank, where it mixes with the already heated one. If the heating element is not given some time, the outlet water temperature will gradually decrease.

Storage type water heater

How to choose the size of the boiler under the sink

For installation under the sink, both a small-capacity storage water heater, for example, Thermex of the Hit series for 10 or 15 liters, and a device with a flow-through principle of operation are suitable. Of course, in the case of installing the second option, there will be more free space, but not every wiring can withstand its powerful heating element, and the use of such a device will affect electricity bills more.

As for the boilers that can be installed under the sink, they differ in the volume of the water storage tank.

1. Ten-liter the option is suitable for a small family, no more than two people. For one person, such a supply of water may even seem redundant, but in this case, you can save money on wasting electricity. It is worth noting that if the tank is not turned off after each use, then you can see a noticeable difference in the bills. If you plan to install a tank for one person, then, as the best option, a flow tank may also be suitable.
2. Fifteen liter the option is perfect for a private house or apartment where the family has one middle-aged child. If the baby is still small, then caring for him will require more water, and in this case, the tank may not be able to cope with a large load.
3. Twenty liter the model today is considered one of the most optimal and in demand. If you carefully use water supplies, you can even take a shower for two adults without much difficulty, which is extremely important if the family lives in a private house. In such a kitchen, you can safely do all the necessary things, since there will be enough water at any cost, even the most impressive. According to experts, this volume is enough to wash all the dishes after a wide feast for five people.

If the active use of the water heater for a large number a person, and there is no way to install a capacitive apparatus, it is better to install a flow option under the sink. It can heat water required volume with no restrictions. However, in this case, it is worthwhile to understand that the consumption of electricity can increase several times. It all depends on how effectively it will be used.

Why safety and check valves are needed

A reliable water heater for washing should be equipped with security team, which includes a pressure regulator - it protects devices from water hammer. If the pressure in the network exceeds 4.5 atm, then for devices with a small tank before safety valve it is better to install a pressure reducer in addition. To collect excess water between the valve and the main tank, you can mount expansion tank. Its formation occurs when water is heated, since it expands under the influence of a heating element.

The storage boiler performs several tasks.

1. Prevents water from flowing back into the line. It guarantees complete filling of the tank. Otherwise, the heater, which is not completely in the water, will fail during operation.
2. Emergency option for draining water from the tank. For example, for dismantling or repair.
3. Protects the inner tank from bursting. This situation is possible when the thermostat does not work due to a malfunction, and the heating element continues to heat the water until it boils. Under the influence high temperature and steam tank sealing may be broken.

It is installed when installing the water heater at the inlet. cold water into the boiler. In the event of a malfunction, the user will notice that hot water will flow from a cold tap. When such a situation is discovered, urgent repair protective device. Otherwise, the consumer will pay for heating unnecessary water.

Safety valve

Sink water heater manufacturers

When buying, it is recommended to pay attention to the country of origin. Usually the most economical option is Chinese production , but after a small amount of time it will take to replace the main parts, which will lead to additional expenses. These manufacturers include Polaris, Ballu. However, it is these economical options are the most in demand today. More reliable are models of German, Swiss or domestic production, such as Thermex, Electrolux, AEG, Gorenje.

How to install a water heater under the sink

In most cases, all materials needed to install and connect such equipment are included in the kit. If necessary, the missing elements should be purchased before starting the installation work. For example, in many budget models non-return valve is missing.

The installation process looks like this.

1. Water heater pipes are equipped with shutoff valves.
2. A protective check valve is installed on the cold water pipe, a tap on it, then an adapter for a metal-plastic pipe.
3. Only a tap and an adapter for a metal-plastic pipe are installed on the hot water pipe. Instead of polypropylene tubes, you can also use flexible eyeliner, which is most often included in the kit, but the first option is more reliable. Besides metal-plastic pipes have a larger diameter, which reduces pressure and improves water supply.
4. The flexible hoses of the mixer are being dismantled and the tees are being installed at the water intake point after the shut-off taps on the water supply. From the cold water pipe - for supply to the boiler, hot - for switching when hot water is turned off.
5. Connecting the tank with appropriate connections. During operation, it is necessary to seal all connections.
6. To prevent puddles on the floor from the safety valve, it is best to install a drain from the drain pipe with an outlet to the sewer or any container.
7. Since this is electrical equipment, an outlet should be connected to the water heater. To protect the equipment in the shield should provide local machine.

It is possible to set the desired water temperature and connect the heating elements of the water heater only when the tank is completely filled.

A water heater under the sink is the best option for small spaces. The type of equipment, capacitive or flow, is selected in accordance with the purpose of the device and the number of consumers. Installation is simple, but if a person has never dealt with plumbing equipment, it is better to entrust the work to qualified craftsmen.

In apartments, there are often interruptions in the centralized hot water supply. This necessitates the installation of a water heater. It is especially relevant in the kitchen, when you have to wash grease and other contaminants from dishes. If you do not already have such a device in your house, then you must decide which model to choose.

The main types of instantaneous water heaters

Usually in the kitchen, water consumption is not so high, so an instantaneous water heater is selected in the room. Principle of operation electric model It consists in the contact of cold water with a heated heating element, which allows the liquid to reach the desired temperature. Instantaneous water heaters for the kitchen are represented by two varieties:

• pressure;
• non-pressure.

The last type of device is a small volume container, which is located above the tap. To understand the design, you can imagine a simple washstand. The container is filled with water, which leaves through the hole from the bottom. Now you need to add a boiler to this design.

It is chosen quite rarely, since the intensity of the jet is quite low. The valve that limits the flow of water is similar to the one that is built into the toilet bowl. The float changes its position depending on the water level. When it goes down, the float goes down and releases the valve, freeing the water to move. As soon as its level reaches the required level, the float rises. This design eliminates the overflow of the system.

Such a instantaneous water heater for the kitchen has a faucet that has a diffuser. Water passes through a small diameter hole, which allows you to increase the pressure for comfortable use. Over time, the passage hole can become clogged with particles of rust, sand and other impurities that are found in tap water. Therefore, you need to be prepared for the need to periodically replace this part of the heater.

The advantage of this design is the possibility of self-filling the tank, which is convenient for giving. In the event of a breakdown, the heating element can be replaced. Such heaters are quite cheap, and their dimensions are very compact. The disadvantage of such devices is their low efficiency at high energy costs. Some consumers note that devices of this type are characterized by uncomfortable placement. They do not have a heat-insulating layer, as in accumulative models. Another disadvantage is that dirty water can quickly disable the device.

Pressure flow water heater

For the kitchen can be pushy. It is more practical and works on a similar principle. The difference is expressed only in the fact that the water is supplied under pressure. This appliance has a thermostat to control the temperature. The power of the heating element can be changed, which will affect the water supply. With less pressure, the water will heat up better.

Pressureless instantaneous water heater for the kitchen is divided into two categories:

• faucet heater;
• stand-alone device.

The first option attracts with compactness and appearance. All complex structures are excluded, like labyrinths of pipes and large tanks. Compactness is ensured by a heater that is built into the faucet. The design is a modified mixer, in the body of which an electric heating element and microcircuits are placed. Using the mixer lever, you can change the parameters of the heater.

The tap is powered from a conventional outlet, and the power of the average device is 3 kW. It is impossible to provide a large volume of hot water with such parameters. Therefore, the water heater delivers about 4 liters per minute, the final value depends on the initial water temperature.

A flowing water heater in the kitchen can also be represented by a stand-alone device that is connected to the plumbing system and a faucet flexible hose. Depending on your needs, you will be able to choose the variant of the device in terms of volume, configuration, size and power.

Advantages and disadvantages of pressure models

The advantages of such heating devices are:

• good pressure;
• compactness;
• ability to control power consumption and temperature.

However, models of this type have their drawbacks, namely:

• difficulties during installation;
• high cost of the device;
• impressive energy costs.

How to choose a water heater by manufacturer: Aquatherm faucet

When choosing an instantaneous water heater in the kitchen for washing dishes, you should pay attention to a device that imitates single lever mixer. It provides ease of control and has a simple design. When you turn on the heating element, you will see how the light comes on, which will allow you to understand whether there is movement inside the device. The case is made of plastic, it has the shape of a cylinder. The water intake pipe runs from below, there is a thread for connecting a flexible outlet.

Opinions on functionality and protection against breakage

Installation is quite simple. The process will be no different than replacing any other plumbing fixture. The water supply pipe is made of stainless steel, which meets hygiene requirements. Inside the design there is a heating element, which provides high functionality. The device has a flow sensor, which is very convenient during operation.

A flowing water heater has one important advantage, which is to refuse to work in the absence of water, which eliminates the failure of the device. Inside there is isolation of water from the heating element, which guarantees safety.

Atlant water heaters: consumer reviews

Before you make a purchase, you should read the instantaneous water heater reviews for the kitchen. Devices from the manufacturer "Atlant" are no exception. In contrast to the previous design, the Atlant models have only temperature control. The design is supplemented with a spiral ceramic heating element, which provides high efficiency.

Power is regulated by the rotary handle ranging from 30 to 85 °C. Consumers say that in the kitchen there is rarely a need for such hot water. The device is able to regulate the pressure, so the flow is constant, which is very popular with the hostesses. The power of the equipment will not be enough to supply shower water, so it can only be used in the kitchen. But to wash dishes, hands and draw water with it, according to consumers, is quite real.

Appearance and cost

By appearance Atlant water heaters are almost no different from Aquaterm devices, but the handle in the first version is at the back. has a diffuser, so the water flows in thin streams. One of the electric instantaneous water heaters for the kitchen can be bought for 3,000 rubles, which consumers consider a bargain. Such equipment is also suitable for giving. It is noteworthy that the device will not break if slightly contaminated water is distilled through it.

Finally

If you prefer an instantaneous water heater to your kitchen faucet, there are several options to consider. Among others, we should highlight the Supretto model, which has a white cylindrical body. Shower outlet is not provided here.

Connecting the device does not take much time, it will be enough to dismantle the old crane. Fasteners are included in the kit. The design is installed on the edge of the sink or screwed to the countertop. The productivity of the device reaches 1.3 liters per minute.

Summer is a wonderful time of the year. But not without a fly in the ointment. Summer is the time of widespread shutdowns of hot water supply. Somewhere hot water is turned off for a short time (for example, for a week, ten days), and somewhere people are deprived of it for months (it happens that water is turned off for the whole summer). One way or another, many citizens experience inconveniences of varying "severity" associated with the lack of hot water. In this material, I collected several high-quality household electric water heaters, capable of solving the most, perhaps, unpleasant "summer problem" - to provide the user with hot water.

Information for thought

Let's start with what modern domestic water heaters actually are. They are divided according to the method of heating. There are storage water heaters, instantaneous and bulk. In the first case, the design of the water heater provides for a container with a volume of 5 to 500 liters (in this material, we will be mainly interested in small-volume water heaters - for “ordinary” kitchen needs) with a heating element placed inside. Water is heated to a predetermined temperature in storage water heaters in advance, before the use (consumption) of water. In this case, heating occurs at quite low power(except for large volume water heaters). It turns out that hot water is constantly inside the storage water heater. As the flow rate comes cold, which also heats up. The storage water heater allows the consumption of hot water by several water points at the same time (however, for small "kitchen" models this is not always true). True, if water is used actively, then the storage water heater may simply not have time to heat the “new” incoming water to the desired temperature - you will have to wait a while.

Another thing is a tankless water heater. Since the water is heated directly when passing through the heating element of such a water heater, there is no need to wait until it heats up - everything happens almost instantly. A flowing water heater due to the lack of a water tank is a much more compact device than a storage one. However, there are also disadvantages arising, by the way, from the advantages: due to the rapid passage of water through the heater, it does not have time to become really hot - warm water flows from the tap (there are exception models, but there are not many of them). In addition, there is no possibility of providing heated water to several water points. Finally, instantaneous water heaters are noticeably more voracious than storage water heaters in terms of energy consumption (after all, they need to quickly heat water, this requires high power). Many flow models require a special connection procedure - running a separate large-section cable from the electrical panel. Note, however, that with a small “kitchen” water consumption (for example, for washing dishes), electricity bills will not increase much.

Bulk water heater - for places (premises) where there is no permanent water supply system ( centralized water supply). Great for cottages. It's just a metal or plastic water tank with a faucet and a heating element inside. Such heaters are hung on the wall above the sink. There are models that are sold immediately with a sink in the kit. Water is poured into the tank of such a heater manually. Water is heated to a certain temperature, which is maintained due to the presence of a thermostat.

There are also gas instantaneous water heaters (they are also called "columns"). However, such devices are mainly used in homes where there is no centralized hot water supply. They provide fast heating of large quantities. running water. In houses with gas water heaters there is simply no problem of turning off hot water (but if the cold water is turned off, there will be no water).

Storage water heaters

Let's start a detailed acquaintance with the "tribe" of household electric water heaters with storage models. We emphasize that we tried to find for you exactly the models that can be used for "kitchen" needs (nevertheless, "Culinary Eden" is about the kitchen in all its manifestations). That is, this one will be, basically, water heaters of small volume, which can, for example, be mounted under the sink - they do not take up much space.

A large family of various water heaters is represented in Russia under the Ariston brand. In the kitchen, for example, models of the PRO SMALL line are suitable. It presents five accumulative models of different capacities: ten liters (two models), fifteen liters (two models) and thirty liters (one model). All storage water heaters Ariston PRO SMALL can be mounted under the sink or above it (depending on the availability of free space). The power of these water heaters is from 1200 W (models for 10 and 15 liters) to 1500 W (30 liters). The maximum water heating temperature for PRO SMALL models is 75°C. The heating time of a full tank for ten-liter models to a temperature of 45 ° C (you can wash dishes or take a shower) is 29 minutes. Fifteen liters will heat water to this temperature in 44 minutes. Thirty-liter model - in 70 minutes. The weight of models with a capacity of 10 liters is 6.6 kg, 15 liters is 7.4. A thirty-liter water heater Ariston PRO SMALL weighs 12.8 kg. The maximum working water pressure is 8 atmospheres. Tank coating - finely dispersed enamel.

Note that Ariston PRO SMALL water heaters have implemented various technologies to ensure the high-quality operation of devices, increase the efficiency of operation. So, the technology of uniform distribution of water in the tank - Nanomix (a specially designed form of a water divider) - helps to reduce the heating time, get the right amount of warm water faster. Super dense polyurethane thermal insulation ensures minimal heat loss. These rectangular water heaters are welded using Micro Plasma TIG technology (argon-arc) for maximum leak protection. The cost is from 3.5 thousand rubles * (10-liter PRO 10 R / 3 model) to 4.5 thousand rubles (30-liter PRO 30 R / 3). Dimensions of the most capacious model (height, width, depth): 446 × 446 × 360 mm.

Another series of Ariston compact water heaters is SHAPE SMALL. There are also five models here, the same displacement as the models of the previous series (also two ten-liter models, two fifteen-liter models, one thirty-liter model). The main difference between the models of this series and PRO SMALL is titanium internal coating tanks of water heaters (Titaniun Plus technology), which provides excellent protection of the “insides” of Ariston SHAPE SMALL water heaters from corrosion.

A system for protecting the heating element from scale is provided - self-cleaning (the surface of the heating element with a special treatment that reduces the intensity of scale formation). The maximum operating temperature of water heating, heating time up to 45 ° C, power, weight - these parameters are the same as those of the Ariston PRO SMALL models. Ariston SHAPE SMALL water heaters also feature Nanomix technology and polyurethane thermal insulation. Argon-arc welding was also used to reliably connect the seams of rectangular water tanks. The cost of a thirty-liter model (SHAPE 30 R / 5) is about 5 thousand rubles. SHAPE 30 R/5 dimensions: 446×446×360 mm.

The next storage water heater is a very recent premiere from Ariston. Models VELIS QUICK HEATING (QH). This is a series of more capacious than previous wall-mounted water heaters (tanks with a volume of 30, 50, 80 and 100 liters). They can be mounted vertically or horizontally. At the same time, the information on the display (here in full electronic control) will always be displayed correctly - the picture will be flipped depending on the mounting method. One of the features of the novelty is the function of accelerated heating of water QUICK, which is sure to be appreciated by “active modern people who value every minute” (quote from the press release). Thanks to this function, the water heater will prepare water - it will heat 40 liters to 40 ° C in 30 minutes (in the thirty-liter model - a smaller volume in less time). Water can be used for any kitchen needs or to take a shower (if the water heater is installed in the bathroom, there is no possibility of servicing several water points here). In addition, thanks to the electronic timer, if desired, you can pre-program the desired water temperature and the time by which it should be ready.

The tank of the new Ariston VELIS QH storage water heaters is made of high-quality stainless steel with a special AG+ proprietary coating (a coating based on silver ions that creates protection against bacteria and resists corrosion processes). All Ariston water heaters have protection against overheating and electric shock. The maximum power of all VELIS QH models is 2500 W. The maximum water temperature achievable with these water heaters is 80°C. The cost is from 9 thousand rubles (30-liter ABS VLS INOX QH 30 model) to 16.5 (100-liter model - ABS VLS INOX QH 100). Dimensions of a hundred-liter model: 1275 × 490 × 270 mm.

Instantaneous water heaters

The most affordable in terms of cost, but at the same time good quality a series of instantaneous water heaters - Electrolux SMARTFIX. These are excellent flow models for a city apartment or cottage (one with running water). Compact Electrolux water heaters SMARTFIX provide you warm water for different needs. The line has models of different maximum power (from 3500 to 6500 W) and different performance (from 2 to 4 liters of warm water per minute). The heating element in all models is copper. All models - nine in total - have three power modes: low power, medium and high power. Models differ from each other in maximum power, performance, as well as the presence or absence of a shower head or a faucet head in the delivery set. Models with faucet and shower have letter designation TS (e.g. SMARTFIX 6.5 TS), with faucet only - T (SMARTFIX 3.5 T), with shower only - S (SMARTFIX 5.5 S). The cost is from 1.5 to 2 thousand rubles. The dimensions of all models are the same: 270×135×100 mm.

A series of flowing wall-mounted water heaters Thermex System - models are more powerful. There are three versions of Thermex water heaters in this series: 6000, 8000 and 10000 W. Accordingly, different performance (unfortunately, Thermex does not provide information on performance). There are six Thermex System water heaters in total - three in white, three in the Chrome version. Price from color solution does not depend - from 3.3 to 4 thousand rubles. Dimensions of all Thermex System models: 170×270×95 mm.

An interesting series of wall-mounted water heaters is Thermex Light. "Interesting" is that the models of this series are a symbiosis of a flow and storage water heater. There are nine models in the line. They vary in capacity. plastic tank("accumulative component") - 10, 15 or 30 liters. The scope of delivery is also different (faucet and shower head, only faucet, only shower). The power of all Thermex Light water heaters is the same - up to 2500 watts. Such “combined” water heaters are convenient to use for various needs: quickly wash dishes in flow mode, take a shower using the accumulated heated water. Dimensions of the most voluminous water heater (MS 30 models): 580×400×275 mm. The cost (depending on the volume of the “accumulative part”) is from 4 to 5 thousand rubles.

Bulk water heaters

Their main purpose, of course, is to provide hot water in the country. Nevertheless, a water heater connected to the water supply is usually purchased in an apartment. At the dacha, the latter may simply not be. That's when a hot water heater comes in handy. Today, there are quite a lot of bulk models in stores at quite affordable prices.

A large family of various bulk water heaters is produced under the Mister Hit brand. We are talking about the family of devices "Dachnik". It includes several water heaters with different tank sizes - from 10 to 120 liters. At the same time, however, the maximum power consumption for all models is the same - 1250 watts. Because of this, of course, the heating time for different volumes of water will differ markedly (one thing is to heat 10 liters, another is 100). But, on the other hand, in country conditions, when the quality of electrical wiring often leaves much to be desired, a small power level is logical. All "Dachnik" - with a thermostat that allows you to maintain a constant water temperature. The maximum water temperature is 75°C (for some models - 65°C). Cases of water heaters "Mr. Hit" (tanks) are made of stainless steel. The cost is from 1.7 thousand rubles (ten-liter model "EVN-10"). The most capacious water heater "Dachnik EVN-120" will cost about 7 thousand rubles. Dimensions of the "one hundred and twenty": 975 × 540 × 260 mm.

Other bulk water heaters of the Mister Hit brand are the Duet family. Here, the main "trick" is that the user, buying any model from this series, receives both a water heater and a sink with a convenient double-leaf cabinet for various country trifles. There is also a series of "Moydodyr". The difference between the models presented in it is that they have a single-door cabinet under the sink. The volume of water tanks in these water heaters: 15, 20 or 25 liters. Tanks are made of stainless steel. The power of the heating elements for all is 1250 watts. Country water heater"Mr. Hit Duet EVN-25" with a double folding pedestal and a metal sink ( stainless steel) will cost about 5.5 thousand rubles when buying. Model dimensions: 810×1330×640 mm.
