Conclusion

The 80 liter vertical flat storage water heater can be an excellent solution for a family. With this equipment you can eliminate problems with hot water supply. If you still cannot decide which manufacturer to prefer, then it is worth comparing the cost of the devices, as well as their completeness and functions.

With the onset of cold weather, more and more often you begin to understand how good it was in summer. There is nothing like a cool shower to escape the heat. But only warm water in the taps will save from the cold weather, which, unfortunately, can be supplied either at the height of the heating season or not at all. In some cities, hot water is not available all year round. A device called "boiler" helps to find a solution in this situation. the words boiler – boiler... Although it would be more correct to say that this water heater... We do not need to delve into the correctness of the names, but we will try to figure out how not to freeze in the cold season.

It looks like a "dry" heating element

As you might have already guessed, the "wet" heating element is located right in the water and accordingly, scale is constantly formed on it. In turn, scale, due to low heat transmission, increases the time spent on heating the water, and accordingly, electricity consumption increases.

"Wet" heating element

To significantly reduce the negative effect of water on the heating element and the walls of the boiler, a special magnesium anode... It is a metal pin, on which magnesium alloy is applied in a layer of up to 30 mm. It is installed in most cases next to the heating element and significantly reduces the formation of corrosion on the internal tank of the boiler. It is better to entrust this business to specialists. They will check the degree of wear and carry out all the necessary "procedures".

Experts advise changing the magnesium anode every 15-18 months, and at the same time carrying out the internal cleaning of the tank, because otherwise rust will “eat through” the metal from the inside more and more. One day the tank may burst, and all its contents will begin to pour out directly from all the cracks. Our experience with the boiler shows that replacing the anode only prolongs the life of the device for a short time. It's all about the quality of our water, which leaves much to be desired and the anode does not cope with the task as much as possible. But here it is also important to take into account factors, how often the boiler is used, how high the temperature is set for heating, whether it is possible to turn off the device during idle hours, etc. All this in the compartment will give you more time to enjoy the purchase, we can talk about 5-7 years of continuous work.

When all the nuances have been studied, let's move on to the choice of the volume of the boiler tank... It is difficult to advise something here. It all depends entirely on the type and size of the room where you will install the water heater. This is often a bathroom or toilet. What matters is the number of family members and how much you are willing to spend on electricity per month.

Recently we saw on sale devices that are designed to save energy. They have a special button, by pressing which you can reduce the power of the device. But experts note a large number of breakdowns of these models due to the fact that the device is worn out faster.

It will not be superfluous to have a special regulator for water heating temperature. In ordinary models this is a common "wheel", in more expensive models - buttons indicating the current temperature.

Experienced experts suggest that it is better to make it possible to turn off the boiler if you know that you will not use it even for several hours. If the device does not have a switch, then you can install this one, correctly and beautifully connecting it on the wall and hide the wires.

It is enough to heat the water and turn off the device, thus, the water heater will not turn on every time at the slightest change in the water temperature (+ - 1 degree). And this will save money and service life. You can turn on the boiler at night, and all day you will have warm and comfortable water.
When leaving for a long period, it is better to drain the water through a special hole in the tap. This is not difficult to do. This will save you from possible boiler breakdown and flooding of neighbors from below.

What volume of a tank for a boiler to choose

When you wonder if how to choose a boiler, then not everyone can understand how much it should be. Many people advise taking a 200-300 liter tank right away in large apartments. But we will allow only partly to agree with this. Such a volume will rarely be used to the maximum, is expensive and difficult to maintain. Therefore, we advise you to choose tanks with a volume of 80 to 150 liters. Even 80 liters. enough to fill the bathroom diluted with cold water at the ideal temperature. If you use only a shower, then 2-4 family members will be able to take it calmly, if you do not sing songs for half an hour 🙂 And a 120-liter device can already cost twice as much as an 80-liter one. Plus, not every room will allow the installation of such units.

Boiler power

Most often, on the shelves you can find models with a power of 1.5 - 2 kW. it most the best option ... Conventional wiring can handle this easily. Better to consult with an experienced installer. He will check your wires for connectivity. Average tank heating time 80 l. to the maximum temperature (it's very hot, believe me) from 2 to 3 hours.
A tank with a maximum volume of 20 liters is suitable for the kitchen. It makes no sense to take more.

Internal coating

Boiler manufacturers advertise two types of boilers to lure customers. Or that stainless steelwhich is more expensive or enamel coating (glass ceramics)slightly cheaper. But the whole point is that stainless steel seems to be better, but the technology of welding seams has not yet reached perfection, so we will get all the same corrosion and, over time, leakage along the seams. Their advantage is far from being the best. Manufacturers are developing more and more advanced stainless steel systems and coatings, so carefully study the boiler model before buying, on the Internet.

The enameled surface is also short-lived, cracks may appear inside over time, through which water will negatively affect the metal and then wear parts again. The fact is that enamel very poorly "tolerates" temperature changes... The service life of such a tank is on average 3 years, it can be extended by setting the operating temperature of 50-60 degrees. This is a perfectly normal value so as not to cause serious damage. But it should be borne in mind that bacteria can accumulate inside the boiler if the water is not used for a long time. We recommend purchasing a boiler that is coated with silver ions. Just a few dollars more, but keeps germs safe.

Boiler location type and shape

The location issue most often becomes in rooms with limited space. The most popular device models with vertical type of accommodation, because take up space along the wall. Plus, in such a boiler, hot water cools down longer. They look like a large barrel-shaped cylinder.

There are also more elongated and flatter water heaters. So called Slimywhich take up much less space in the apartment. Their cost is much more expensive, but their heating efficiency is higher.

Boiler "slim" or flat

There is and rectangular boiler... A little more "slim", but also designed to save space.

The horizontal type of placement of boilers also takes place. Unfortunately, such devices are ineffective in heating and water cools faster.

Installation of a water heater

Most often, the device is placed either in the bathroom or in the toilet. Note that the mount and wall must be the most reliable... The weight of the boiler can reach 25 kg, and if you add another 80-120 liters of water, it may turn out that not every wall can withstand such a load. Therefore, it is better to entrust the installation to specialists; the durability and warranty service of the water heater largely depends on this. The hardest part of all the work is the electrical wiring near the installation site. The standard cable may not be enough and will have to be extended.

Boiler service

As we already wrote, first of all, the internal tank deteriorates, so you need to change it in a timely manner magnesium anode. Try to mark the approximate service period in advance on the calendar. Also, if necessary, you need to clean the heating element from scale. If the water in your area is hard, then maintenance should be done once a year. Be sure to check with the store before buying about the possibility of free cleaning during the warranty period. Try not to carry out maintenance yourself, avoid buying homemade anodes or anodes of questionable quality and manufacture. They can not only disable the device, but be hazardous to health. Original anodes are always sold in branded packaging and are made of very high quality.

There are craftsmen who, to prevent the formation of scale on the heating element, before the water enters the boiler, they install a flask with salt on the pipe. It is not yet clear how practical it is and how it helps to deal with the problem, but the number of such successful reviews is constantly increasing.

Or so special

We advise you to put it on a pipe that fits the boiler special craneso that small rust in the water or some other small debris from the water does not get into the water heater. The filter will sometimes need to be cleaned or changed, but this is better than repairing the device.

Popular models of water heaters

We have selected for you the most popular boiler models, which are gaining the largest possible number of positive reviews. It is difficult to single out any particular favorite among the manufacturers. Let's just say that the technologies are constantly being improved and we can already talk about significant progress in the production of boilers.

That's all our advice for today. As you can see, buying a boiler requires observance of small nuances. But they fade against the background of the fact that you will have hot water in your house or apartment. Now you know more about how to choose a boiler, which water heater is better to choose.

Rising hot water prices have spurred the development of the hot water industry. They also buy them for summer cottages, country house, that is, where people are not constantly, but want to make this stay the most comfortable by connecting an independent and uninterrupted source of water heating. Electrical installations accumulative type are called boilers. Below we will consider the main aspects that are important to pay attention to when buying and using water heaters. The rating, which is built on the basis of live customer reviews, will help to understand the lineup and popularity. The reader will be able to make sense of the myriad of products of this type by taking a closer look at the best boilers.

When choosing, you need to pay attention to such features as:

• the size of the tank can be from 10 liters to 300. But, as practice shows, the most popular boiler-type heaters with a volume of 50, 80 and 100 liters
• power. The higher the number in this paragraph, the faster the device will heat the water and, of course, the greater the energy consumption.
• a heating element. Inside there can be a heating element or a spiral. The difference is that the former are somewhat more expensive, the latter have to be changed more often.
• anticorrosive anode. This is an element that, if necessary, independently removes small cracks in the tank.
• electrical protection. There are device safety standards, the manufacturer must take care of ensuring them in reality.

When purchasing a water heater, many pay attention to such an indicator as its overall dimensions. Therefore, before buying, you need to determine how much water you need, as well as the location of the heater.

Dimensions of storage water heaters

The volume of contained water directly depends on what sizes of a water heater. A heater with a capacity of 50 liters in length is much shorter than a similar model, but with a capacity of 100 liters. Usually tank diameter most heaters do not exceed 45 centimeters.

With an increase in volume, only the height of the water heater increases. For a tank with a capacity of 50 liters, the height is 50-60 cm, with a volume of 80 liters, the height reaches 75-85 cm, 100 liters up to 115 cm and the height of the heater with a capacity of 150 liters reaches 160 cm.

Flat Tank Heaters

It should be noted that heaters having a large height and diameter have an advantage over smaller analogues. According to this factor, it can be assumed that a large thermal insulation layer which will significantly reduce heat loss. Therefore, you need to think carefully before purchasing such a heater.

However, such devices have a number of disadvantages. So, a flat heater having a depth of 27 cm has a very large height. The result is a flat heater, which, in fact, has the dimensions of a conventional one. Square-shaped water heaters

A water heater, the dimensions of which are small, and the shape is close to a square, are widespread. Moreover, inside such a water heater has round sectionand its diameter is 45 cm. Due to its size and shape, this water heater has a long service life. Heaters of this type belong to the premium segment, have an expressive appearance, and the thermal insulation of such tanks is at a high level.

Slim water heaters

A large number of manufacturers produce a water heater with a round cross-section - its dimensions do not exceed 38 cm in diameter. This type of heaters is very reliable. They are widely used when installation space is very limited. Installation produced in existing niches and various non-standard places. As already mentioned, with a decrease in thickness, the height of the heater increases. For example, a slim heater with a capacity of 50 l has a height of 80 cm, 80 liters - 115 cm, 100 l - reaches a height of 140 cm.

Instantaneous water heaters

There are two types of flow heaters on the market - pressure and non-pressure. Non-pressure heaters have low energy consumption and are able to heat water at two points if they are located nearby (for example, a kitchen and a bathroom). For long service, it is necessary that the water heater (dimensions do not matter) be installed in accordance with all installation rules. This is because the pressure in such a device is equal to atmospheric. Therefore, when the boiler is on, the tap must be in the open state. Otherwise, such a heater will not last long.

To turn on the pressurized flow heater, you just need to open the tap. The device is equipped with a hydraulic regulator, which switches the device on and off due to the difference in water pressure at the inlet and outlet.

More comfortable is a water heater with automatic electronic control. This system not only automatically turns the device on and off, but also keeps the temperature at a constant level, which completely eliminates human intervention in this process.

The key parameter of the heaters when choosing is the volume of the tank. "The more capacious - the better"? This statement is not always true, because it takes a lot of time to warm up an impressive amount of water. Although you can give preference to a powerful unit, but in this case it will empty your pockets when paying for electricity.

How to determine the appropriate volume of the water heater? Indeed, the compactness of the device itself and the continuity of the flow of hot water will depend on its size.

The same model of a water heater is always available in several versions, ranging from the smallest to largest tanks. But unlike flow types, where the pneumatic flow of water passing through the device instantly heats up to a maximum temperature, the tank is first filled in the storage heater and only then temperature increase water in the tank. As it cools, the sensor starts heating cyclically, which allows water to always remain at the required level of heat.

Save on volume or not?

According to statistics, a city dweller uses from 100 to 400 liters of water every day, most of which is hot. Moreover weighty volume consumed to no avail, inefficient.

Naturally, each person’s water consumption is purely individual. One will be able to use the volume of the water heater to take a full bath, leaving a certain amount of water for washing dishes or hands, but for the other member of the family you will need to wait a bit to heat up the next portion of water.

But if you don't care at all water saving and electricity, and the financial security and potential of electric networks allow you to use a powerful heater, in this situation, purchase several devices with capacitive tanks of 200-300 liters.

Waiting time for water heating

The temperature level of hot water set from the control panel of the heater can be adjusted in the range from 30 to 80 degrees Celsius. But according to safety precautions, you need to fix it within 55-60 degrees in order to avoid injury from hot water.

Based on the fact that the temperature of cold water in the summer months is about +15 degrees, and in the winter months +5, and water with a temperature of about + 30 + 40 degrees is comfortable for swimming, different volumes will warm up in different times. For example, a volume of a water heater of 100 l warms up water to 60 degrees in about 5 hours.

As the consumption of hot water, it is gradually diluted with cold, continuously flowing into the tank. After mixing, 160 to 250 liters of heated water are formed. Undoubtedly, the true values \u200b\u200bare less, because with decreasing hot water the general temperature indicators of the contents of the tank decrease.

The volume of the water heater used for different needs varies depending on personal preferences. So, individually for kitchen needs, a small 5-liter heater may be suitable. It will allow you to rinse your hands and some dishes. If you do not save on water, a water heater with a 20 l tank will be suitable.

To use the shower, you need a tank capacity of at least 50 liters, taking a bath - 80-150 liters. Therefore, the selection of capacity should be optimally coordinated with specialists focusing on the personal needs of the user.

Consumers using centralized hot water supply remember that most often in summer (and sometimes in other seasons) there is no hot water. Happy owners of suburban private houses also need to take care of how to heat water for household and personal needs. Therefore, the question of how to choose a water heater becomes almost for every owner.

The option of heating water with gas (gas column) is the most economical option, but it is not always possible to supply gas. You can also use the boiler, working on the products of oil distillation. Such a construction will require a separate room, and in apartments it is completely prohibited.

Since there is electricity in almost all houses, the option of heating water with an electric water heater remains the most relevant. Water heaters of this type are divided into two types: storage and flow. At first glance, they differ only in size: cumulative - larger (depending on the volume of the tank), and flow - the size of a shoe box. Consider these two types in more detail.

Accumulative (capacitive) water heater

The storage water heater consists of a tank filled with water, in which a tubular electric heater is installed. TEN heats water in the range from 35 to 85 degrees Celsius and turns off (the temperature is set by the user). When the temperature of the water in the tank drops by 0.5 degrees, the water heater automatically starts to warm it up to the indicated mark.

Instantaneous water heater

The instantaneous water heater works according to a different principle - cold water from the water supply passes through a tube (a tubular electric heater) and, depending on the amount of hot water consumed, includes a certain number of heating elements. Instantaneous water heaters do not have their own tank, all the water is heated not in the tank, but when passing through the tube with heating elements.

Compare flow and storage water heaters

Before buying a water heater, it is important to decide what type you need and what are the main differences between the two devices.

It remains a profitable solution to choose a storage water heater, for the operation of which you will need from 1 to 2.5 kW of electricity. Such a device is quite enough to provide heated water (from 60-75 ° C) to an apartment or a small private house.

How to choose a high-quality storage boiler

In this section, we consider in more detail the characteristics of the storage water heater, which will help determine the choice of a quality device. Depending on the increase in the volume and quality of boiler materials, the price of a water heater also rises.

How to choose a boiler volume

The most valuable parameter of a storage water heater is its volume. Consider the volume of boilers sufficient for domestic needs (averaged indicators):

• small capacitive water heaters, from 10 to 15 liters, are used for washing dishes and washbasins (for a shower this volume may not be enough), they are usually mounted there - under / above the sink or washbasin;
• small 30-liter boilers are used by bachelors, and for women who pay more attention to water procedures, this volume may not be enough;
• accumulative boilers from 50 to 100 liters are most often used in apartments. Such a volume is sufficient for a married couple (50-80 l), and for a large family with children (80-100 l);
• large water heaters with a capacity of 150 l - for large apartments and medium-sized houses. Used in families who prefer to take a bath instead of a shower;
• the largest water heaters (200 l) are used to provide large apartments or a private house with hot water. This capacity is enough to provide a family of 6-8 people. A huge boiler is installed on the floor, because of the heavy weight, wall mounting is not permissible according to safety regulations.

When choosing a water heater, you should not choose a model, guided only by volume indicators. For more capacious boilers, more time will be required for heating. Sometimes it’s more profitable, for example, to install a water heater with a volume of 50-80 liters in the bathroom, and another, small volume, for hot water in the kitchen.

Power and heating time

Electric water heaters operate on the principle of "boiler". Depending on the power of the heater (an electric heating device in the form of a metal tube filled with a heat-conducting electrical insulator) and the volume of the boiler’s capacity, the speed of heating cold water to the indicated temperature also depends.

Tenes are divided into:

1. "Wet" TEN. A heater from a copper tube is immersed inside with a water tank. Over time, due to direct contact with water, the heater is covered with a layer of scale, as a result of which the time for heating the water increases significantly. Another disadvantage of using a water heater with a "wet" heater is galvanic steam (electrochemical corrosion), due to the occurrence of a chemical reaction between the heater and the walls of the tank. Not recommended for use with mineralized water;
2. “Dry” heating element. The heating tube is placed in a protective flask or casing and does not have direct contact with water. Thanks to the protection, the metal tube does not overgrow with scale and there is no electrochemical corrosion. Water heaters with a “dry” heating element have a longer operational life.

Power distribution, depending on the volume of the tank:

• water heaters with a 30 liter tank use power from 1 to 1.5 kW;
• boilers with a volume of 50-80 l use power from 1.5 to 2.0 kW;
• large devices with a capacity of 100-200 liters with a capacity of 2.0 to 2.5 kW.

The speed of water heating depends on the possibility of the mains, if the power supply to the outlet is limited to 2 kW, then, accordingly, large models of water heaters (150-200 l) will spend more time for heating than indicated in the specifications.

The amount of time required for heating water (75-80 о С) in various models by volume:

• 30 liter boiler with a power consumption of 1-1.5 kW, heating time - 1-1.5 hours;
• 50 liter boiler with a power consumption of 1.5 kW, heating time - 2 hours;
• 120 liter boiler with a power consumption of 2 kW, heating time - 4 hours.

From these we get: do not chase a large volume, for the average family, from 50 to 80 liters are enough, and the heating speed differs almost twice from the model with one and a half volume.

Types of the inner surface of the boiler

Models of water heaters with an inner surface of glass-porcelain and enamel have a good price-quality ratio. The disadvantage of such boilers is considered to be sensitivity to sudden changes in temperature, as a result of which a crack can form. This problem can be solved by lowering the upper mark of the temperature to 60 ° C, but in such a situation it is often necessary to heat the water.

A titanium-coated stainless steel boiler will differ significantly from an enamelled water heater. As a result, due to the durability of the stainless steel, the life of the water heater increases.

Extra options

When buying a storage water heater, you need to pay attention to related products and equipment, which include:

• The presence of additional additives in the coating material of the container (for example, zirconium), which further disinfect the water.
• The safety valve protecting the water heater during a sharp jump in water pressure in the pipes.
• A set of brackets or anchors for fixing the boiler to a wall or floor.
• The kit includes an adapter for 380 V (if this is intended to be connected to the network), or a standard plug for connecting to a household network.
• Protective system against power surges.
• Automatic water heater shut-off system in the absence of water or mains voltage.
• Cleaning filters for water.
• Pressure reducer - to lower the water pressure upon entering the tank, in case of increased pressure in the water supply system (if the pressure at the entrance to the apartment exceeds 5 bar).

The best models of water heaters

In a variety of boiler models it is easy to get lost. Given all the characteristics (water heating time, price, life, design) and many other features, here is a list of the best models from reliable manufacturers:
