Specifics of storage water heaters
A structure consisting of a tank with a heating element inside, which gradually heats the entire volume of water in the container, is called a storage water heater.
If we consider more detailed diagram, then it contains the following elements:
- Frame. All internal parts of the device are hidden under it. For its manufacture, both expensive and cheaper materials are used. The most high price for models with an aluminum body, this is followed by stainless steel, and the most cheap option- plastic.
- Thermal insulation. Prevents heat losses. The thicker its layer, the longer it is maintained optimal temperature water inside, the device performs the function of a thermos more efficiently, and its operation is cheaper.
- Internal capacity of the water heater. It is made of metal, having a protective layer in the form of an enamel coating or a higher quality glass porcelain coating.
- Pipe for collecting heated water. Its layer, in accordance with the laws of physics, is located above the cold layer. For this reason, the selection point is located at the top.
- Supply pipe. Through her cold water from the system enters the tank.
- Anode. The material from which it is made contains a high percentage of magnesium. Designed to protect the heating element by attracting scale to itself; it settles not on the heating element, but on its surface.
- Heater. Includes 2 elements - heating element and thermostat. The first can be open or closed and is designed to heat water, and the second to control its temperature.
- Thermostat. Can automatically turn on and off the heating element when the set temperature is reached.
- Water heating sensor. Electronic or pointer. The latter shows only the approximate temperature, while the former, which is highly accurate, is included in more expensive models.
- Lid. Protects the user from electric shock.
Electrical storage water heaters- effective devices for independently providing the home with hot water. They have high efficiency, do not consume a large number of electricity. Thanks to your success, you will always have a supply of hot water.
Electric water heaters have a wide range, including models of different shapes and design volumes. There are many additional functions, making their operation economical
In garages and country houses where there is no running water, tankless water heaters powered by the electrical network are used. They are equipped with a thermal limiter, light indication, and temperature regulator. They are suitable for installation in rooms where the temperature is not lower than +1 degrees C and not higher than +40.
Tank inner lining
It is traditionally believed that a stainless steel tank is more reliable than a regular steel one. This is true, it’s not for nothing that manufacturers give a 10-year guarantee on them. You should know that these containers have a weak point - a seam that is susceptible to corrosion. In many models it is covered with a protective layer.
A good alternative to stainless steel is the enamel coating of a steel tank. Additives are added to the enamel to improve its properties. In elite models, glass-ceramic coating is used, silver and titanium ions are sprayed.
To apply these enamels, complex, expensive technology is used. Which of the listed water heater options will be better, everyone decides for themselves.
In Europe, they mainly use only enameled tanks, considering them more environmentally friendly than containers made of of stainless steel and less allergenic
The silver-containing coating disinfects water, prevents corrosion, and prevents the formation of microcracks. Increased stability A heat-resistant coating in the form of titanium spraying, obtained by nitriding titanium at temperatures above 1 thousand degrees C, is resistant to strong heating.
Most enamels used by manufacturers tend to repel scale.
Submersible and steatite heating elements in comparison
There are 2 types of heating elements in storage boilers - submersible or “wet” and steatite or “dry”. Units with the second type of heating elements are more reliable.
There is no contact of heating elements with water here, because they are placed in a special flask filled with quartz sand or oil. The steatite element has a longer service life, but also almost doubles the cost of the water heater.
A “wet” copper heating element is something like a boiler; it quickly becomes covered with scale, which reduces its thermal conductivity.
The “sacrificial” magnesium anode facilitates the fight against calcium salts deposited on the surface of the heating element. It works on the principle of galvanic interaction of conductors. The more electronegative magnesium accepts oxygen ions, thereby preventing the destruction of iron.
The magnesium anode does not protect the heating element from scale in literally. It simply simplifies the fight against it, taking the brunt of the blow, as a result of which it oxidizes and breaks down, therefore it must be periodically replaced
The scale deposited on the heating element, consisting of magnesium salts, has lower carbonate hardness and is distinguished by a looser structure. This sediment can be removed mechanically. The service life of the electrode and tank body is reduced not only by scale, but also by suspended particles that scratch their surface. Installation will save you from these risks.
The tank can contain either 1 heating element or more, up to 6 pieces. If there are already 2 heating elements, the boiler can be operated in economical heating mode - PowerProf. If the boiler has a power of 2 kW, there is a choice between an economical mode with a consumption of approximately 800 W, an average - 1.2 kW or a maximum - all 2000 W.
The design of electric heating equipment provides a possibility that you can handle yourself, strictly following the instructions.
Advantages and disadvantages of the accumulative type
A storage water heater or boiler has such a significant advantage as low energy consumption. Its consumer powers are in the range of 0.9-6 kW.
The boiler works from single-phase network, it is possible to connect the unit both in a city apartment and in rural house. The main thing is that there is a 220-230 V outlet. Water can be supplied to several points at once.
Image gallery
The boiler can store a large volume of water heated to 65-85 degrees C, periodically heating it. There is a large range of models with tanks capable of holding from 10 to 300 liters. When consumed, hot water enters the mixer, and if necessary, it is brought to the desired temperature by diluting it with cold water.
The thermal insulation layer allows for minimal heat loss. Usually they do not exceed 0.5 degrees C in 1 hour. In models in which as thermal insulation material polyurethane foam is used, placed between the tank body and a layer of anti-corrosion coating, the temperature per day decreases by only 10 degrees.
The thermal insulation layer made of foamed polyurethane is environmentally friendly and has low thermal conductivity. It has good moisture permeability and does not lose its properties throughout the entire operational period
If the electrical wiring is of high quality, then as an option you can connect several devices with a power of 3 to 8 kW. In old-type houses, connecting such devices is problematic. Here it is better to use a storage boiler that does not create a large load on the electrical network.
Instantaneous water heaters, like storage ones, are divided into 2 types: non-pressure and pressure. Devices of the second type are embedded in hot and cold water pipelines, then warm water will flow from any tap in the house.
An excellent solution for apartment owners not connected to centralized hot water networks is. He cooks quickly sanitary water for sinks in kitchens and bathrooms. The devices turn on and off automatically, reacting to the pressure of the liquid.
When you decide to purchase an instantaneous water heater, decide for what purpose you need it. Based on this, choose a device according to the required performance and power
Non-pressure flow devices have a maximum power of 8 kW. They can provide warm water to only 1 point at a time. If you need hot water to flow from each tap, then it will have to flow from each of them.
Although these models are cheaper than pressure models, they are not worth purchasing for a large house or apartment, but for a dacha where people live only in the summer, they work well.
The disadvantage of portable flow-through water heating devices is that they work at only one point. But required amount water heats up quickly without turning on the central network. The temperature is adjusted by increasing or decreasing the pressure
Criteria for choosing gas instantaneous water heaters will be presented, the contents of which we recommend that you familiarize yourself with.
Safe operation of equipment
The main element that guarantees the safe operation of a storage water heater is a thermocouple. It automatically turns off the heating element after heating the water to the set temperature. A thermocouple consists of 2 conductors having different resistances.
If the thermocouple stops functioning for some reason, it comes into operation safety valve. It is installed at the inlet and includes a valve with a spring, which is in a relaxed state at a pressure in the system of up to 7 atm.
As soon as the pressure reaches a critical value, the spring compresses under its action and opens drainer. Some of the hot water flows out, the pressure inside the tank decreases.
When choosing a water heater, you need to pay attention to its protection class, especially if water shutdowns occur frequently. The best choice in this case would be water heaters closed type with protection class IP 24, IP 25.
In a instantaneous water heater, a pressure sensor is responsible for safety. It turns off the heating elements automatically when the pressure in the water supply drops when the tap is closed.
You can learn how to use a water heater correctly. Compliance with operating rules significantly extends the operating life of the equipment.
Criteria for comparing water heaters
Manufacturers are constantly upgrading their products and releasing improved models. Comfort in your home will depend on how well you can choose a water heater. To a large extent, the reliability of equipment is determined by which company produced it.
An important question facing the buyer is whether the water heater is suitable for you in all respects. To make an error-free choice, you need to know the main evaluation criteria.
To objectively evaluate the advantages of a storage water heater model, you need to compare according to the following parameters:
- Volume. Tank capacity may vary. Nai in great demand units with an average storage volume of 30-100 liters are used.
- Power. For high-quality models it is far from small.
- Type of heating element. It can be in the form of a spiral or heating element.
- The presence of a “sacrificial” anode.
- Electrical protection class.
- Manufacturer popularity.
The price of the unit is not in last place, but in pursuit of cheapness, do not forget about quality. Excessive savings can result in many problems during operation.
Overview of manufacturers of storage-type units
Manufacturers that have long earned the trust of consumers include, first of all, Ariston. Storage water heaters are quite affordable in price, have a stylish design, have an impressive list of additional functions, and a high degree of safety.
An auto shut-off mechanism protects against electric shock if the tank breaks down; there is a special valve that is triggered when the pressure is high.
The new model of the Ariston VELIS PLUS INOX water heater attracts with its elegant design. It is equipped with two stainless steel tanks with individual heating elements and a touch screen.
The European manufacturer Thermex also occupies a leading position; in particular, the ID 50 V model is in great demand. It has compact dimensions, good design, and low power. There are check and safety valves. This model has a serious drawback - the tank is susceptible to corrosion, because... he has a weak anti-corrosion coating.
Name from Bosch Many people associate it with the concept of reliability. Its products always top the water heater rating tables in the global market. Devices from this manufacturer are distinguished by durability, convenient settings, optimal power and an appropriate price justified by high quality.
Products from the Czech manufacturer of storage water heaters Drazice also have positive reviews. They are designed to heat water up to 95 degrees C in large volumes - at least 90 liters at a time. The models have high-quality corrosion protection and low heat loss.
DRAZICE has released a new line of OKHE SMART water heaters. Their main feature- presence of a “smart” thermostat
The Swedish company Electrolux also produces water heaters with excellent performance characteristics. Particularly popular is the CENTURIO EWH 80 model, equipped with a spacious stainless steel tank (80 l) and a tubular heater. It is distinguished by excellent thermal insulation and stylish design.
This model only lacks an anode, which protects the tank and heater from corrosion. Having chosen Electrolux models, you should make sure that they are not collected in China.
Manufacturers of instantaneous water heaters
For owners of small apartments, heaters manufactured by AEG are a good choice, but on the condition that the electrical wiring is new. All parts of the device that can be exposed to water splashes have an anti-corrosion coating; the material of the tank has shock-proof properties.
For individual consumers, the disadvantage is the high energy consumption and high cost.
Electric flow AEG water heaters will fit even into limited space. on his front panel there is a temperature regulator
Electrolux, in addition to storage water heaters, also produces flow models. Their advantage is safety, a clear interface, and ease of installation. Based on some reviews, the heating elements are not durable.
Polaris Mercury has a streamlined shape that allows you to install the device anywhere. Heats up water very quickly. Some inexpensive models have low efficiency, the limit for them is 40 degrees C.

Despite their apparent similarity, storage water heaters have quite significant differences. Depending on the materials used and design characteristics O
What properties are necessary for a good water heater?
Storage water heaters can help save any amount of hot water. The only difference is their size: larger size, the longer it takes for the water to heat up.
Execution of internal capacity
Characteristic feature of working conditions
Accession storage heater water.
All storage water heaters have a container or tank in the middle of them. Let's figure out which tank should have a reliable heater. The cold water entering it already has abundant pressure of 2.5..3.5 bar. Anything higher must be cut off using a pressure regulator installed at the entrance to the living area.
Cold water is supplied to the water heater from below for proper layer-by-layer distribution. To prevent water from flowing out of the tank when the water supply is turned off, a check valve is installed at the entrance to it. Water intake is controlled using mixers on the devices. Water increases in temperature with increasing temperature. Heating water in a closed volume leads to a significant increase in pressure, which is accepted by the walls of the tank.
Storage water heater device.
An increase in pressure to emergency values is protected by 2 design solutions. The very first thing is air bag on top of the tank, which will be about 10% of the container volume. The air, compressing, compensates for the temperature increase in water. Secondly, if the pressure in the middle of the tank increases beyond the emergency value, the relief valve will operate. The response limit of this valve varies in the range of 5.5-7.5 bar.
This is quite a significant pressure, and the water heater must maintain it. When it is new, problems do not appear, but after some time they are possible. The thing is that the heaters have tanks made of steel, and it is prone to rust. The water heater heats ordinary tap water without any special preparation. The substances melted in it give it the properties of an electrolyte. As a result, rust develops in the middle of the tank.
Galvanic rust occurs due to potential differences between the different metals from which the water heater and the connectors at its inlet and outlet are made. When various pairs metals are in contact through an electrolyte, the metal with the greatest negative potential is oxidized. For steel it is -0.63 V, for copper -0.2 V, which means that the steel in this pair will rust. To minimize this type of rust, steel or plastic connectors should be used.
Electrolytic rust develops even when metals with the same potential come into contact through the electrolyte electric field. It is the result of the presence of uncontrolled electrical currents. For example, in case of grounding leaks. As a result of electrolytic rust, metal with a large negative charge releases free ions into the electrolyte and corrodes.
Ways to protect the tank inside
What measures do manufacturers suggest to increase the durability of the heater tank? The very first thing is this surface coating inside protective coatings. Secondly, the location in the middle of the tank is metal with a large negative potential. In most cases, this is magnesium, which is called a sacrificial cathode, and such protection is cathodic. Third, the production of stainless steel tanks.
Enameling is used as a protective coating.
Gas storage water heater.
Storage water heaters with enameled coating relatively inexpensive, but very durable. The service life of such a coating greatly depends on the stage of adhesion of the coating to the base, its thickness and the correspondence of the coefficient of temperature increase of the enamel used compared to this characteristic for steel. Flexibility and resistance to cracking are also essential.
Manufacturers use different variants coatings Particularly popular varieties are glass porcelain or glass enamel. They firmly protect steel walls tank, but only until cracks appear from compression and constant expansion due to temperature changes. These materials are quite fragile and can be damaged by the slightest impact, and therefore water heaters with an enamel-coated surface inside the silicate-based tank require only careful handling.
A lot of manufacturers say that they use an unusual recipe for making enamel, which makes their water heater especially durable. Various additives are used to improve the properties of enamel.
For example, there are offers for water heaters with titanium enamel. This means that a small percentage of titanium has been added to the glass enamel. This material improves the hygienic properties of the tank and increases the resistance of the enamel to many aggressive environments. But the addition of titanium does not make the enamel more resistant to cracking, and in a proportion of more than 4% it even increases its fragility.
Installation diagram of a storage water heater.
The thickness of the steel sheet that was used in its production has a radical effect on the strength of the tank and its resistance to rust. The most inexpensive and fragile tanks are made from a 1.5 mm thick sheet, in the average price category they use a 2 mm sheet, and very expensive tanks have a wall thickness of 2.5 mm or more. A water heater with a normal tank wall thickness is never too light. The heavier the water heater, the more durable it is.
Sometimes, to eliminate rust, it seems that the most drastic method is used. The walls of the tank are made of stainless steel. This can actually significantly increase the operating life of the heater. But the whole point is that the tank is not made of a common steel sheet and welding must be used.
To prevent the anti-corrosion properties of stainless steel from deteriorating during the welding procedure, specialized, expensive types of stainless steel and specialized welding techniques must be used. European manufacturers rarely do this, with the exception of many expensive water heaters from Scandinavian manufacturers.
There are many relatively inexpensive products available with stainless steel tanks. In fact, they are all made from Chinese parts, and the working life of such products is not very noticeably superior this indicator for inexpensive enamel coated heaters. And sometimes it turns out to be much less, because... Thin steel is used for manufacturing, and welding joints are made using low-cost methods.
Even if the tank is made of stainless steel, a magnesium cathode must be placed in the middle of it to eliminate oxidation of the seams and heating elements. The magnesium cathode dissolves during operation and must be replaced occasionally. This should be done once every 1-1.5 years, along with cleaning the tank from sediment and scale. In reality, this is not often done by anyone, and many buyers like to change the entire water heater every 3-4 years.
Electric elements
Scheme of using a storage water heater.
The quality of temperature sensors and control equipment is of great importance for the reliability of the water heater. In our situations, where there may be constant voltage drops, electronically controlled devices are less reliable. If a voltage stabilizer is not installed in the room, mechanically controlled water heaters must be used.
Repairing failed automation involves significant difficulties, because... Such spare parts are in great short supply and are expensive. On the contrary, if mechanical regulator asks for a replacement, it is not difficult to find an auxiliary part for replacement, and it will not cost a significant amount.
Diagram for connecting a storage water heater to a water wire.
They are distinguished by a heating element system with closed and open heating elements. If the heating elements are open, they have a particularly narrow contact with water and the most large area contact. As a result, heating occurs quickly. But with all this, the heating elements are intensively overgrown with scale and corrode.
In systems with closed heating elements, the heating elements are enclosed in a flask and do not have direct contact with water. The flask is made using the same technique as the walls of the tank. And just like them, it has an enamel coating or a stainless steel body. These heating elements are more reliable and do not require frequent cleaning.
Electric storage water heater.
Storage water heaters are produced by most manufacturers. And it is impossible to say for sure which of them are very reliable. We can only roughly note the price groups in which different heater options are offered. Which heaters occupy the upper price group, which are in the middle, and which in the lower.
Manufacturers such as Stiebel Eltron, OSO belong to the prestigious class. European manufacturers AEG, Gorenje, Electrolux, Fagor, Ariston are considered ordinary representatives of strong middle peasants. The lower segment is dominated by domestic Thermex, and various Chinese products are also widely demonstrated trade marks or brands that position themselves as local or European, but at the same time they still assemble from Chinese kits. Crushing is quite figuratively speaking, and different manufacturers may have models of different levels.
When selecting a water heater, we can suggest not to run after dumping prices, but to select, first of all, quality and the optimal price ratio. There is also no need to purchase overly expensive models. Often, long warranty periods for the tank and electrical equipment require that installation work and annual maintenance be performed under warranty by certified centers, which together can add up to the price of another tank.
And therefore especially good and a cozy option It is considered to be the purchase of a mid-level water heater made in Europe with an enameled tank and closed heating elements. In this option, you can count on 5-6 years of trouble-free operation, then the heater will need to be replaced. It is necessary to take into account that the operating life of the heater largely depends on the quality of your water, the water pressure at the inlet and the stability of the voltage in the electrical network.
To increase the service life of the storage heater, do not heat the water to temperatures exceeding 65°C. At very high temperatures, the processes of rust and scale formation are greatly intensified.
A storage water heater will ensure stable delivery of hot water to any home. Which company is better to buy equipment depends on the technical characteristics of certain models. When choosing a decent unit, you should pay attention to design features, water needs and the number of people living in the house.
A high-quality unit with an attractive design will become an integral addition to a stylish interior.
How to choose the right storage type electric water heater
An important advantage of storage models, in contrast to flow-through ones, is the provision of hot water at any time.

An electric storage-type water heater (boiler) is a heat-insulating tank for heating water to a certain temperature (in the range from 35 to 85 degrees), made of anti-corrosion materials (copper, often steel).
Thanks to its design, it is able to keep water warm for several hours. After it cools down, the boiler automatically turns on to heat it up and, when a certain temperature is reached, turns off again, which is very practical and economical. Some boiler models are equipped with additional elements or functions:
- Antibacterial coating.
- Accelerated water heating.
- Manual/automated control.
Advice. If you live not in a private house, but in an apartment, then you should opt for a storage type boiler. He has significant benefits before the “flow”: the ability to operate from a network with a voltage of only 220 V with low power consumption, which does not affect the performance of the device.
Let's consider the key advantages and disadvantages of storage type heaters.
The advantages include:
- low power (up to 2 kW) - only a stationary outlet will be enough to power the device;
- ability to retain heat long time(even during a power outage);
- one boiler serves all water intake points in the apartment simultaneously;
- ability to function even with weak pressure water.
Disadvantages:
- impressive dimensions (in most cases);
- installation complexity;
- limited volume of water, when using which you will have to wait several hours for the next “portion”;
- Regular use of the device requires constant replacement of the anode, which protects the tank from corrosion.

Finally, a few words regarding what you should consider when deciding on the boiler capacity for your apartment. To select a model optimal capacity, think about what the boiler will be used for. So, if you are planning to install a water heater for hand washing, a 5-15 liter device will be enough. If you plan to take a shower, 30-50 liters will be enough. If you have big family or you are a fan of soaking in the bath, then start from the figure of 80-100 liters.
Advice. When choosing a water heater with a tank of a suitable volume, do not forget about one important aspect - the speed of heating the water. So, if a 15-liter boiler heats water to 50 degrees in 15 minutes, then an 80-liter boiler will take about 3 hours.
