How to choose a domestic water heater. Storage water heaters with indirect heating
stable delivery hot water in any dwelling will provide a storage water heater. Which company is better to buy equipment depends on specifications certain models. When choosing a worthy unit, you should pay attention to the 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 part of a stylish interior.
How to choose the right electric storage water heater
An important advantage of storage models, unlike flow models, is the provision of hot water at any time.
With flow units, the water quickly warms up and cools down after the system is turned off. Storage devices provide heated water for a long period. Heating is carried out automatically after cooling the water.
Storage water heaters have huge advantages. Which company is better to choose mechanisms depends on the scope of the unit: private households, offices, workshops or summer cottages.
Features of the device vertical and horizontal models
The unit is a liquid container with a built-in heating element. The operation of the structure differs little from the operation of a thermos. The water heats up to a certain value, and then the machine turns off, but keeps the heat.

After some of the water is used up, cold water moves in its place. Such units can be pressure and non-pressure.
The equipment is assembled from the following parts:
- magnesium anode that protects the surface from rust;
- heating elements;
- heat-insulating layer;
- safety valve to reduce pressure;
- thermostat.
Useful information! The heaters have a power rating of 1.5-2.5 kW. Models work in two modes heating and standby.
Advantages and disadvantages of storage equipment
When making a choice: which storage water heater is better, it is worth knowing the advantages and disadvantages of this equipment.
Product advantages:
- heating element with low power;
- connection of several water supply points to one device;
- no additional wiring required;
- the device is installed at any distance from the water intake point;
- ease of operation;
- available stock of heated fluid.
The disadvantages include the significant dimensions of the devices. For the bathroom you will need a unit with a spacious capacity. Hot water comes only after preheating.
The nuances of the selection of water heaters for summer cottages
Many are interested in: how to choose a water heater for a summer residence. When buying, you should pay attention to anti-corrosion protection. Also worth considering. That the design over time is exposed to destructive factors: temperature extremes, aggressive substances and high pressure.
Welds are considered a weak element of such structures. It is better to purchase units that have a cylindrical shape.
Choosing a boiler with a tank
Such equipment is often equipped with tanks of different capacities. For the kitchen, containers of 20-25 liters are suitable, for the bathroom - 65 liters. If you plan to install a shower, then the water consumption will be 40-50 liters.
A 120 liter device can provide even a large family with water, subject to economical consumption.
Anti-corrosion protection for heating tank
A special coating is used to protect storage equipment from corrosion. It is used not only as protection, but also as a component of the design of the unit.
The stores offer enamelled, titanium and stainless steel tanks. The anti-corrosion coating is made of titanium sputtering and glass porcelain. The budget options include glass-ceramic coating.
What type of control to choose?
Electronic type control is characterized by ease of use and stylish appearance.
The cost of an electric flat storage water heater of 30 liters is higher than the price of mechanical equipment. In constructions, the required values are set once. Further control is carried out using a relay.
Choice of devices by power level
All boilers accumulative type equipped with one or a pair of heating elements, which differ in power rating. Tanks up to 15 liters are equipped with one heating device, with a power of 1 kW. Equipment of 50 liters is equipped with a device of 1.5 kW. Large units with tanks of 100 liters will need heating elements of 2-2.5 kW.
Characteristics of heating elements
Teng is a heating element in a boiler. The mechanism consists of a steel tube in the center, and the free space is filled with a heat-resistant compound. Such a product has a compressed structure. Such a product has the shape of a spiral.

Overview of Termex devices
The best domestic brands include Termex. The company's products are equipped with heating elements of 1.5 kW. Many devices are designed to be installed horizontally.
Today, boilers are gaining more and more popularity among users. These sources of hot water supply help to live comfortably all year round, regardless of the schedule of heating networks. In the leading positions are precisely those devices that can accumulate and retain heat. This makes you think: which brand of storage water heater is best for your home?
Storage water heater device
Before talking about the proposals of specific brands, you should decide on the requirements that such equipment must withstand. Each of them is important:
- volume;
- power;
- type of heater;
- fastening type;
- tank cover;
- availability of options.
Capacity options
To deal with the volume, you need to know for what purposes the device is purchased. If only for washing dishes, then a “baby” of 15 liters will be enough. However, users are usually not content with little, and therefore a good boiler should involve taking a shower and even a bath. For such purposes, a capacity of 100-120 liters will be enough - the water heater will successfully meet the needs of a family of three (the hot volume will also be diluted with cold water).
How to understand how much volume is needed for your family? Usually to apartments they buy boilers with a capacity of 80 to 100 liters (the small dimensions of the bathroom and kitchen simply won’t allow more). In the cottage such a restriction is removed - here it is really possible to allocate space even for a 200-liter tank.
Power and heater
The possibilities of the internal reserve are closely related to the power of the boiler. Depending on the volume indicators, one or two heating elements are used in the unit. For a small tank of 15 liters, a power of 1 kW will be enough, 30-50 liters already increase consumption to 1.5 kW, and in the case of large boilers from 80 liters and above, a heating element with a range of 2 to 2.5 kW is activated.
To the question of heating element: in its classical form it will be made from copper tube, inside which there is a conductive nichrome thread. This type of heater is conventionally called " wet» due to the fact that it works directly in the water. Such a service is fraught with consequences in the form of scale growing on the element.
To prevent the part from failing, it will need to be cleaned once a year.
"Wet" water heater heater
Recent innovations in this area include "dry" heater: when the heating part is placed in a special flask, which will come into contact with water, heating it. Such a solution turns out to be much safer and more reliable, but it will also cost more.
"Dry" heating element of the water heater
Even more impressive figures of the amounts will be at the aggregates with two heaters: such devices will heat the water much faster. Having reached the set temperature, one of these two parts (usually with a power of 2.5 and 1 kW) is turned off - this is what is included in the program.
Reliable fastening
We figured out the main criteria, now it’s worth considering where the device will hang. For installation, it plays a big role, vertically or horizontally, this technique will hang on the wall. It all depends on the specific model: flat options are placed horizontally. Usually, a storage electric boiler looks like a cylinder or a rectangular parallelepiped.
This device is attached with mounting brackets on dowels in the wall surface. It is desirable that it be a carrier, but if this is not the case, then for greater reliability, a through stud should be installed - after all, sometimes you will have to withstand more than a centner of weight.
Which water heater to choose - a traditional cylinder or an ultra-modern and air-conditioning device? Better one that will fewer seams. And one more thing is the pressure that the water in it exerts on the equipment. Cylinders carry it best.
Internal coating
For the inner surface of the tank, a variety of materials are used - here are high-quality enamel, and a titanium layer, and stainless steel, and glass ceramics. There are also corrosion protection- the magnesium anode located inside the tank is responsible for it.
In some models, a fine-dispenser interspersed with silver is provided. This "know-how" makes it possible to claim the disinfecting properties of the water flowing from the device.
Simple and clear control
Even the cheapest brands of modern water heaters are sure to have temperature controllers and thermostats, which will turn on and off the heating in a given program in automatic mode.
And if the model is expensive, then it will a priori be smart, because in this case the work is entrusted powerful processor. Its task is not only to maintain the required temperature, but even to disinfect the water. Another "trick" users call the ability to draw up a user's schedule and, if necessary, turn on both heating elements for a faster result.
Usually such devices look stylish and presentable. The impression is complemented by a touch screen, on which settings and changes are made with a light touch.
Overview of water heaters from different companies
Many global manufacturers of equipment are ready to offer interesting models of boilers of their brand. It is possible to understand which water heater of which company will be better only by conducting a detailed analysis of the strengths and weaknesses devices.
Advanced "Ariston"
The leading position is occupied by products from Ariston. This Italian brand tries to keep abreast of global trends and produces high-quality equipment that meets all consumer requirements. Products are represented by boilers with a volume of 30 to 100 liters (and corresponding to the volume of power). The inner surface is also interesting - it can contain both simple enamel and the one with silver in the AG + marking. Titanium and stainless steel are immediately present. Of the benefits - the possibility of electronic control and even the presence of modern touch screens.
Additional features include divider application, which will not allow the heated and newly received portions of water to mix. Bribes and the fact that the developers have taken care of the likelihood of occurrence emergencies- in this case, the protective relay will not allow electric shock and prevent damage to the entire device. And the device itself simply will not turn on if there is no water in the tank.
It was not without some shortcomings. These include the lack of fasteners.
You can better understand the whole “essence” of the device using the example of the Ariston ABS VLS PW 50 model, which has average statistics - a tank of fifty liters and a power of 2.5 kW. This allows the 490x800x270 mm device to heat water up to 80 degrees. There is a mandatory thermometer and even a limit on the heating temperature. The protection provides for blocking the inclusion of the device in the absence of water. There are 2 heating elements, and internal coating is stainless steel. The device is suspended vertically.
Users are also satisfied, talking about the fact that the equipment does not heat up in any way outside, with network outages there are no problems with it. By the amount of water, you can safely pour a bath, and there will be more to take a shower.
Elegant "Electrolux"
Another famous brand Electrolux has also stood the test of time (in 2019 it will cross its centenary milestone). Over the years, only one thing has not changed - the undoubted quality of products. But the functionality has only increased.
- In the models of this manufacturer there is a limit sensor, various relays for protection against overheating, there is a mandatory thermometer.
- The glass-ceramic surface of many models will not accumulate rust. In addition, there is a function for water disinfection.
- Cleaning the heating element is easy and simple thanks to a thoughtful process for this.
- Finally, the two-heater mode significantly saves electricity.
Electrolux is always flawless first-class products. But there were some drawbacks: technology is usually very expensive, and the heating elements themselves are short-lived in operation.
One of the most popular offers of this company is Electrolux EWH 50 Royal for 50 liters with a power of 2 kW. It heats water up to 75 degrees. It has rather compact dimensions - 433x860x255 mm and is mounted on the wall in a vertical form. The device is quite simple to operate (it has a mechanical one). Many protection options are provided: against overheating, against operation without water, check valves and safety valves. And in the functions, in addition to the standard temperature restrictions on heating, there is an accelerated process.
"Burning" for everyone and everyone
The Slovenian manufacturer Gorenje tries to meet the requirements of all its consumers. That is why all their devices are with very different power and volume of water. However, almost all of them have enamel and stainless steel as an internal coating. Also, the units are provided with hydraulic control, there is protection against overheating and a switch-on sensor, there is a safety valve.
For example, the Gorenje GBFU 80 E B6 with a size of 454x816x461 mm has a displacement of 80 liters and consumes 2 kW of power. Mounting on the wall in a horizontal form (which saves space a lot) implies a bottom connection. The maximum possibility when heating water is 75 degrees. There is even frost protection. Users note that the device is very economical and quickly heats up water, but it has a problem of knocking out plugs, therefore, you need to think about pulling a separate cable.
Convenient "Atlantic"
The Atlantic brand produces boilers from 30 to 160 liters. There are horizontal and vertical mounting options. Interesting internal coating: inside the tank, it represents titanium alloy with cobalt and quartz inclusions(and this is already protection against water of the fourth class). Device owners like their stylish concise design and build quality.
The manufacturer has a compact narrow model with a size of 338x918x345 mm - Atlantic O'Pro Slim PC 50 for fifty liters and a power consumption of 2 kW. The device has a maximum heating capacity of 65 degrees.
Specialized manufacturer "Termex"
Here you can quote the official website of the company: “There is a fact that cannot be argued with. If a company has been producing water heaters alone for more than half a century, while its volumes have increased 20 times over the past 10 years alone, and its products are well bought in 160 countries of the world, then these are good water heaters. This is what true professionalism is all about.”
The equipment of this brand is not cheap, but Thermex boilers are always of excellent build quality, durability and efficiency in operation. The latter criterion is confirmed in the Thermex Champion ER 80V model, which has 80 liters of displacement heated with just 1.50 kW. The dimensions are quite compact even for small apartments - 450x730x470 mm, and the device is hung with the help of vertical mounting. Users joke about this boiler: they say, it is from the “turn on and forget” series. The only drawback of the device is that every six months you have to change anti-corrosion anode.
domestic proposals
Which company would be better to buy a storage water heater for your apartment? Perhaps it will be one of the models of Russian manufacturers.
For example, a certain popularity in the territory of the Russian Federation was won by Alvin's boilers. The line called "Success" turned out to be successful - both in terms of quality and capabilities. The model "Success-15" will operate with a power of only 1.25 kW, however, the tank volume will not exceed 30 liters. The automation of the equipment will not allow the water to rise above 70 degrees (this will happen in about 40 minutes). Even special system that retains heat when the boiler is off. This is also facilitated by the 1 mm thick stainless steel used in technology, which has a positive effect on the durability of the boiler.
Boiler Alvin line "Success"
Another excellent domestic example is "Moydodyr". The brand also specializes in small heaters (about 15-30 liters), which is enough for washing dishes and for personal hygiene in the country. The device operates from 1.25 kW, is protected from overheating or the possibility of switching on "dry". The design itself is also interesting - a frame with a heated 20-liter tank and a sink (which resembles the famous fairy tale hero). A full tank will heat up in about 50 minutes, while not rising beyond the limit of 70 degrees.
Water heater "Moydodyr"
Which storage electric boiler to purchase must be decided based on the requirements of future users and their number. The main thing is to perform the installation correctly and follow the operating rules in the future, then the device will show itself as a reliable and trouble-free assistant.
An indispensable device in the country or in a private house without a central hot water supply. He allows you to quickly and without hassle to heat water for domestic needs- washing dishes, showers and baths. Water volumes depend on the type and power of the water heater, so it is important to consider all the features of the proposed models and choose the most suitable option.
There are several types of water heaters. Type of heating element they are subdivided into gas and electric. When installing a geyser, it is necessary to coordinate with the supervisory services and connect the chimney. Therefore, most consumers prefer to choose an electric water heater.
Electric water heaters according to the principle of heating water are divided into two types:
- flowing;
- cumulative.
Video: instantaneous and storage water heaters - how to choose the right option.
Flowing
main feature heaters of this type - no storage tank, due to which their dimensions are very compact. The instantaneous water heater can be installed anywhere, including hidden under the sink, in a wall cabinet or in a niche.
In a flow heater for heating water, a heating unit is designed, usually it is made of copper - corrosive resistant material with excellent thermal conductivity. The heating is switched on by means of a thermal heater.
The heating elements in the flow heater are turned on only when the water is turned on; for this, the device has a sensor that responds to the flow rate. It can be hydraulic, with a built-in diaphragm and stem, or electronic, with a microprocessor. Water supply and output are carried out through pipes. A mesh filter is provided at the inlet for water purification from solid inclusions and salts.
Flowing water heaters are open or closed type.
The former can provide hot water only one draw-off point, for example, a sink in the kitchen.
Closed models can work for one or two points, for example, a sink and a shower.
Advantages of flow models:
- small size and weight;
- simple installation and connection;
- fast, almost instantaneous heating of water;
- less electricity consumption, since there is no need to maintain the temperature of the water in the storage tank;
- no need to pour water into winter period when the temperature drops, which makes it possible to use it in the country;
- water is heated to a warm or moderately hot state, which eliminates the appearance of scale.
Minuses:
- a large load on the power grid, consultation with an electrician serving the house is necessary on the permissible power of the equipment;
- stringent requirements for electrical wiring - the high power of flow models requires connection to the network with a wire with a large cross section through a separate circuit breaker;
- the water pressure in the water supply must be sufficient to trigger the flow sensor, otherwise the heater will not turn on;
- if the house has more than two points of water intake, it is better to provide several instantaneous water heaters, the power of one device is not enough to effectively heat a large volume of water.
Mounting and installation
When choosing a model, it is necessary to take into account the dimensions of the device, while it is better to immediately determine the place of its installation. Compact dimensions usually allow you to install an instantaneous water heater hidden under the sink or above it.
You also need to buy and lay a separate cable to the electrical panel and connect it to a separate machine or RCD. The cross section of the cable cores and the rated current of the machine must correspond to those indicated in the table.
To ground the body of the water heater, it is necessary to connect the grounding core of the cable to the body of the electrical panel (6). The phase and neutral wires are connected to the RCD (5).
The pipes of the water heater are connected to the water supply as shown in the figure. A tee is connected to the cold water supply pipe (1), one outlet of which is flexible hose or pipes are connected to the cold tap of the mixer. The second outlet is connected to the water heater by inserting a ball valve (3) and a strainer (4) into the pipe.
The outlet pipe from the water heater is connected to the hot tap of the mixer (2) also through the valve (3). Installing valves will allow you to easily remove the water heater for repair or maintenance.
Cumulative
A feature of accumulative models is the presence of a tank with a volume of 15 to 200 liters, in which water is heated and its temperature is maintained at a given level. The tank is made of stainless steel and coated with an anti-corrosion layer.
The body of the water heater can be steel, powder coated, or plastic. Between the tank and the body there is a heat-insulating layer that ensures the preservation of temperature. The shape of the body can be any, usually cylindrical or rectangular.
Water heating is carried out using one or more heating elements, which are turned on and off by a signal from the thermostat. It sets the desired temperature in the range from 35 to 90 degrees.
Cold water enters the tank through a fitting equipped with a check valve. The intake of heated water comes from the upper part of the tank, which excludes the discharge of water when its supply from the water supply is interrupted and the device overheats. 
The water in the tank is always hot, so with a volume of more than 50 liters, you can not only take a shower or wash the dishes, but also take a bath. Several points of water intake can be connected to the storage heater, for this it is enough to select the desired volume of the device. To avoid pressure and temperature surges, it is recommended to connect the points through a distribution manifold - you can buy it or assemble it from fittings.
Advantages of storage water heaters:
- the possibility of obtaining significant volumes of hot water;
- you can connect several consumers - a bath, a shower, a washbasin, a sink in the kitchen;
- low power and moderate load on the power grid;
- stable water temperature.
Minuses:
- large dimensions and weight of the device;
- more complex installation and installation;
- prolonged heating of water after switching on;
- to maintain the temperature, the water heater must be turned on constantly, which increases energy consumption by 10-20%;
- the formation of scale in the tank, which gradually reduces the efficiency of the device.
To avoid deposits on the walls of the tank and heating elements, as well as corrosion of the tank under the influence of low-quality water, modern water heaters are equipped with a magnesium anode. It takes over the processes of corrosion and salt deposition, while gradually collapsing.
Extraneous sounds during heating testify to its destruction - hissing, uneven hum. In some models, a light is provided that signals the destruction of the anode. In this case, it is better to buy a new anode and replace it.
Storage water heaters suitable for use in the country, in a house or apartment with any pressure in the water supply, as well as with a low-power power supply.Volume selection
Volume is one of the characteristics of water heaters, on which uninterrupted hot water supply at home depends. If water is needed only for kitchen sink or a washbasin, for example, in a small private house, then a volume of 15-30 liters is enough. For a large house, you need a boiler of 200 liters or more.
When choosing the volume of the water heater, its dimensions must also be taken into account. It is worth considering that boilers with a volume of 200 liters or more are usually produced in the floor version, less - in the hinged version.
It is generally accepted that for a family of 2 people a water heater of 50-80 liters is enough. It will provide hot water for the kitchen, bath and shower. For 3-4 people you need a 120-200 liter boiler.Video about storage models: which heater is better
Installation and connection
When installing a wall-mounted storage heater, it is important to correctly calculate the load on the wall so as not to cause its destruction and the device to fall. The weight of the heater itself is indicated in the passport, it is necessary to add the weight of water to it. Based on the resulting value, you can choose the place of its attachment.
As a rule, for water heaters with a volume of more than 50 liters, choose bearing wall. For fastening, use the brackets and hardware supplied in the kit, and in their absence, anchor bolts and hooks.
When installing a water heater, it is important to observe it working position without any deviations. Heaters with vertical installation hung on two hooks, with a horizontal one - on four, for holes specially designed for this purpose.
A storage-type water heater is connected to the network in the same way as a flow-through one, but since the power of these devices usually does not exceed 2 kW, there are no special requirements for wiring. The device is grounded, the phase and neutral conductors are connected to the corresponding contacts of the RCD (7), usually it is installed in the electrical panel (8).
To connect a water heater to a water supply network, the diagram below is usually used. A tee is installed on the cold water supply pipe with a shut-off valve (1). To one of the layers, a pipe is connected to the water heater. A safety valve (4) must be cut into it. It prevents spontaneous draining of water, and also allows you to relieve pressure when the water is heated.
To drain water from the water heater, a bypass with a three-way valve (6) is provided. To supply air to the tank when draining the water, a tee with a valve (5) is provided on the hot water pipe. The outlets to the draw-off points are indicated in the figure by positions (2) and (3).
To fill the water heater with water, it is necessary to open the hot water taps, as well as the valve on the safety valve. The three-way valve on the bypass must be closed. As the tank fills, air will come out of the taps, and after the water starts flowing, the heater can be turned on.

The choice of the manufacturer
Not less than frequently asked question arising when choosing a water heater - which company's device will turn out to be reliable, convenient and economical. As a rule, the buyer trusts trusted brands, and it is important not to overpay for the big name of the company.
The most popular devices on the market are well-known companies such as Ariston, Bosch, Electrolux, Thermex. These companies represent a wide range of models of different power and volume, equipped with modern automation. They are safe to use and durable.
Having considered all the characteristics of water heaters, you can make a choice in favor of a specific type of water heating and the manufacturer, and buy a device that meets all the requirements and wishes. At correct installation and operation, the water heater will last long years providing stable water heating.
Since we cannot rely on the availability of hot water, we need to stock up on water heaters for emergencies. Modern models very comfortable, compact, and most importantly - effective. Despite this, you may get quality model which received bad customer reviews. Below we have selected for you a rating of the 10 best storage electric water heaters of 2018.

What should you pay attention to when choosing a boiler?
Surely you have repeatedly encountered the problem of the lack of hot water in the house, which is why you ended up on this page. But what if you have never chosen a water heater? Below we describe the main criteria that you should pay attention to when choosing a storage water heater.
Water heater type
- Cumulative- the most popular type of water heaters that heat water in a tank, inside of which there is a heating element. As you use, cold water enters and is heated to the desired temperature. The features of this type are the use of low power, and the ability to connect several water points.
- Flowing- in these water heaters, water instantly becomes hot passing through the heating elements. Features of the flow type are small dimensions, and the fact that you do not need to wait for water heating.
- Bulk- this option is most suitable for those places where there is no own water supply system (dachas, garages). Water is poured into the tank manually by the user, and there is a tap on the side for supply warm water. As a rule, such models are installed directly above the sink.
- heating tap- this is a regular faucet with a small built-in heating element. The principle of operation is the same as that of the flow type.
In this article, we will consider only storage water heaters (boilers), if you want to learn more about instantaneous water heaters, follow the active link.
Tank volume
This indicator should be calculated based on the number of family members and their needs for hot water. To do this, it is customary to use the average figures for water consumption per 1 person:
It should be noted that in a family with Small child, the cost of hot water increases significantly.
Tank lining
The two most popular are:
- Stainless steel - it is a virtually indestructible material that has high strength and reliability. The disadvantages include the inevitable appearance of corrosion, with which manufacturers have already learned how to deal with.
- enamel coating- despite the outdated technology, enamel is in no way inferior in terms of the characteristics of steel. Modern additives that are added to chem. composition, have properties similar to metal. At right technology applying enamel, the coating will serve you for a very long time.
Anode
Anti-corrosion anode significantly increases the life of the device. It neutralizes the environment and prevents oxidation, that is, the appearance of corrosion on the welds. The magnesium anode is replaceable, the average service life is up to 8 years (depending on the conditions of use). Modern titanium anodes do not need to be changed, they have an unlimited service life.
The best storage water heaters up to 30 l
Boilers with a small volume are ideal for washing dishes and washing. The shower will need to be taken very sparingly and the second person will have to wait for reheating.
3 Oasis VC-30L
Third place in the category "boilers up to 30 liters" is compact model Oasis VC-30L. small size allow you to place the device in small apartment, and protection against overheating and overpressure makes the operation of the device completely safe.

Hot water for modern man is not a luxury at all. He is in dire need of it. In this regard, many apartment owners in which centralized system water supply cannot be provided with hot water around the clock and throughout the year, sooner or later they begin to think about purchasing such a device as a water heater.
Modern market household appliances offers many models. However, not everyone can answer the question of which water heater is better to buy for an apartment. Let's try to figure it out.
Electricity or gas?
Which water heater is better to buy in an apartment? Feedback from experts and consumers confirm that when choosing, it is necessary to determine which energy source will be used when operating this device. Depending on what will be brought up to heat the water, the units are divided into two types. They can be gas or electric.
Which water heater is better to buy in an apartment? Consumer reviews indicate that gas appliances are cheaper to operate. At first glance, it may seem that this option would be the most acceptable for apartment owners. However, this is not quite true. The cheaper type will bring the water up to the set temperature very slowly. In addition, to install this device, you will need to involve specialists from gas service. They will charge for laying additional pipes and ventilation ducts. The end result is a pretty decent amount.
Quite expensive and gas boilers, heating an impressive volume of water. In addition, there is no point in placing such units in a small apartment.
As for electric water heaters, all models of this type of device are powered by a network:
220 volts (single phase);
- (three-phase).
Which water heater is better to buy in an apartment? User reviews indicate that the most powerful devices are connected to a 380 volt network. Such devices heat water very quickly, but their cost is quite high. In addition, for such units it will be necessary to carry out powerful wiring, and three-phase networks are not available everywhere. In addition, for old city apartments it is not recommended to choose a water heater that consumes more than 5 kW. Otherwise, the network will simply be overloaded.
If the apartment is located in a new building, then the owner is given the opportunity to choose a more powerful device. How many kilowatts to count in this case can be determined according to the existing project.
Which water heater is better to buy in an apartment? Feedback from many people who decide to purchase this useful device, say that they are afraid of a sharp increase in electricity bills. But you shouldn't worry about it. Electric water heaters with average volume and power indicators, with their permanent job cost the owners no more than a couple of hundred rubles a month.
Installation location
Which water heater is better to buy in an apartment, you need to decide not only based on the type of energy it consumes. Users note that if the project does not initially provide for a place in which the device should be installed, it is quite difficult to find free space. In addition, the entire structure, together with water, has an impressive weight, which makes it difficult to attach it to non-capital walls. All this is taken into account by modern manufacturers who produce wall-mounted and floor-mounted devices.
If you decide to purchase a water heater for an apartment, which of these two types is better? Wall-mounted appliances save space. Floor water heaters are securely installed on the floor and do not cause the risk of collapse even with large volumes of water in them.
When choosing wall variant before buying, you will need to measure the width and height of the free space with a tape measure. This will let you know allowable dimensions water heater and how best to position it.
Wall units are mounted either horizontally or vertically. At the same time, the manufacturer produces universal devices that can be positioned depending on the available space, as well as special models with one configuration or another.
To date, the manufacturer also offers such water heaters that can be installed directly under the sink. However, their main disadvantage is the limited amount of heated liquid.
Volume
This is one of the important parameters that should also be taken into account when choosing a water heater. In order to determine the required volume of the tank, you will need to take into account the required dimensions of the unit, the number of connection points, as well as the number of family members. For those owners who purchase a water heater only for washing dishes, a tank volume of 10-30 liters is sufficient. But to take a shower of water, you will need more (from 50 to 100 liters). If family members are used to taking a bath, then the maximum volume of the tank is required (up to 150 liters).
Device type
Water heaters are of the following types:
Cumulative;
- flowing;
- accumulative indirect heating.
Let's consider them in more detail.
Storage water heaters
Aggregates of this type are the most popular. In such devices, the entire volume of water in the tank is heated. Storage water heaters bring the temperature of the liquid to a certain limit, and then maintain it at a given level. In this regard, such units are the most economical.
What storage water heater is better to buy in an apartment? One that will allow you to use the required volume of water, because when it is fully consumed, you will have to wait again for the heating of a new portion of the liquid. In this regard, when choosing a model, it is necessary to calculate the size of the tank.
Flow type water heater
As for this type of heater, it has smaller dimensions. However, it should be borne in mind that this device does not allow the water to warm up enough and be very hot. At the same time, such units have more than storage units. However, if we take into account that heating occurs only at those moments when the owners go to the shower or wash the dishes, then the costs will not be very high.
But for apartments with old wiring instantaneous water heaters better not to buy. After all, previously designed networks will not be able to withstand the installation of units whose average power exceeds 6 kW.
Which instantaneous water heater is better to buy in an apartment? To select a device, you will need to evaluate the load that will be placed on the unit.
What power water heater is better to buy in an apartment? In the event that up to three people will use the water, it should be approximately 12 kW. Such power will allow you to keep the performance parameter at the level of up to three liters of hot water for one minute. In this case, the maximum supply temperature will be at least fifty degrees.
How to determine which is better for an apartment?
The choice of such a unit is also based on the available parameters of its power supply. As a rule, water heaters of this type have it at 220 V with a frequency of 20 to 30 Hz. However, in cases where there are problems in the form of power surges in homes, a model must be purchased at 30 Hz.
Storage water heaters with indirect heating
According to user reviews, such units are the most economical. The fact is that their work is carried out with the simultaneous inclusion of a single-circuit heating boiler. In winter, such water heaters use the same energy that is intended for heating.
The main disadvantage of such a device is its difficult installation, which involves inserting into the heating system. But if we consider the advantages of using this unit, then it is worth noting that there is no need to connect it to the electrical network.
Indirect heating devices are installed, as a rule, in urban private or country houses that have autonomous system heating.
Performance and Power
Which electric water heater is it better to buy an apartment? For selection the best option the device must be looked at in the instructions for its performance, which directly depends on the power.
The strongest dependence of these indicators is observed in instantaneous water heaters, as already mentioned above. In such units, for comfortable consumption of hot water, the power must be above 12 kW. IN storage devices enough power of 2 kW. The performance of this type of device will be at a sufficient level.
heating elements
When deciding on the choice of a heater, this parameter should also be paid attention to. Manufacturers offer models that provide either one or two heating elements.
In the first case, water heaters use energy, which is controlled by automation. At the same time, to maintain the set temperature level, the device turns on the economy mode. After the full use of water in such units, further heating is carried out slowly.
Which water heater is better to buy in an apartment? With high hot water consumption, models with two heating elements are the most preferred option.
Other selection criteria
Modern devices for heating water are distinguished by low heat loss. This figure is only a few degrees during the day. This becomes possible due to the good thermal insulation of the tanks, for which polyurethane foam, fiberglass or expanded polystyrene are used.
When choosing a water heater, you can compare the heat loss rates for different models. To do this, you need to clarify this parameter in the instructions attached to the device.
Equally important is the service life of the device. On average, it is 5 years, but at best, the manufacturer will indicate a period of up to 7 years. This parameter characterizes the reliability of the water heater. After all, the service life will directly depend on the material used for the tank, as well as on the quality of the applied anti-corrosion coating.
When buying a water heater, you need to focus on its price. It will be directly dependent on all the above parameters, as well as the brand of the device.
Manufacturers
