Top 7 rating according to KP
1. Zanussi ZWH/S 80 Smalto DL (18 rubles)
This storage water heater with a capacity of 80 liters differs from competitors in quiet operation. The power of 2 kW allows you to heat water up to a temperature of 70 degrees, and the volume of the tank is enough for a family of 2-4 people.
The device comes in a stylish silver case. The front panel has a display with bright numbers that are visible even at a distance of 3 meters. Inside the water tank is divided into two parts, each of which has its own heater, thanks to which the device combines two heating modes. During economy mode, only one side works, which saves power consumption. At maximum power, 80 liters of water will heat up in 153 minutes.
2. Hyundai H-SWE4-15V-UI101 (5 500 руб.)
This model is an excellent low-power option for those who need hot water only for the kitchen (for example, in the country). In addition to its compact size and weight of 7.8 kg, it has an interesting design and relatively high functionality. The tank of the device is designed for only 15 liters. At the same time, the economical power of 1.5 kW will allow you to heat water up to 75 degrees, which more powerful models can boast of. You can control the maximum temperature thanks to a convenient regulator.
The heating element of this water heater is wear-resistant due to the stainless steel from which it is made. True, the use of glass ceramics for the internal coating of the tank looks like an ambiguous solution. Despite the high heat resistance, it is quite fragile, which forces you to be extremely careful when transporting (if necessary).
3. Ballu BWH / S 100 Smart WiFi (18 rubles)
This water heater is primarily convenient for the versatility of installation – it can be placed both vertically and horizontally. In addition, the model attracts with an interesting design with rounded edges.
The front panel has a display, a step switch and a start key. The 100 liter tank is heated by a coil in a copper sheath. In 225 minutes, the system is able to heat water up to 75 degrees.
The main advantage of this water heater is the ability to connect a Wi-Fi transmitter, with which you can control the device settings via a smartphone. With the help of a special application that exists for both Android and iOS, you can set the start time of the boiler, the number of degrees, the power level, and also start self-cleaning.
This feature will allow you to start the device shortly before leaving work, and not keep it warm all day. Thanks to this, when you return home, you will have hot water without having to spend extra on electricity.
4. Gorenje OTG 100 SLSIMB6 (10 rub.)
This representative of the Slovenian company Gorenje is one of the best options in its price range. The tank volume of this device is 100 liters, and the power of 2 kW allows you to heat water to a temperature of 75 degrees.
The model is suitable for both a large apartment and a private house – several points of water intake will allow you to use the boiler in several rooms at once. Of the nice additions, one can note the operation status indicators and the temperature limiter, as well as two types of design – dark and light.
Despite the fact that this water heater is equipped with a standard set of protective systems, its weak point is the safety valve. There were cases when, due to an excess of pressure, it came to a rupture, which simply “killed” the apparatus. So in case of purchase, you should periodically check the condition of the valve.
5. AEG EWH 50 Comfort EL (43 000 руб.)
This water heater holds 50 liters of water, which are heated by a heating element with a power of 1.8 kW. Due to this, the maximum temperature to which the device can heat water is 85 degrees.
The walls of the tank are covered with a multilayer enamel coating, which is a patented technology of the company. The coating not only protects the metal from rust, but also slows down heat transfer, which allows the water to stay warm longer, and this, accordingly, saves electricity. Contributes to this and a dense layer of foam under the casing.
Thanks to the electronic diagnostic system, the model can diagnose itself, after which it displays a possible error code on a small display. True, with all the pluses, the device does not have protection against overheating.
6. Thermex Round Plus IR 200V (43 890 руб.)
This electric boiler has a capacious tank with a capacity of 200 liters, which will allow you not to think about the amount of hot water spent. Despite the impressive tank, the device has a fairly compact size relative to analogues – 630x630x1210 mm.
The Turbo heating mode allows you to bring the water temperature to 50 degrees in 95 minutes. The maximum heating is 70 degrees. The speed and temperature can be adjusted with a mechanical setting system. It should be noted that for the speed of heating the heating element is divided into three parts with a capacity of 2 kW each, which, however, affects the consumption of electricity. By the way, this model can be connected to both 220 and 380 V networks.
It must be said about the durability of the tank of this device – the sellers give a guarantee of up to 7 years. Such parameters are called due to the fact that the tank is made of stainless steel 1.2 mm thick and has an increased area of anodes that protect the walls from oxidation.
Of the minuses, it is worth noting the protection against turning on without water, which forces you to closely monitor this factor when using.
7. Garanterm GTN 50-H (10 rubles)
This horizontally mounted electric boiler is perfect for rooms with a relatively low ceiling, whether it is an apartment, home or office. The device pleases with its reliable design – it has not one, but two stainless steel tanks with a total volume of 50 liters.
Seams and joints are made by cold welding, reliably polished, so that corrosion centers do not appear on them over time. This approach to manufacturing allows the manufacturer to declare a warranty period of 7 years.
This unit is equipped with a convenient adjustment mechanism that allows you to switch between three power modes. At the maximum, the indicator reaches 2 kW.
How to choose an electric boiler
What to look for when choosing the best electric water heater?
Power
Speaking of power, it should be remembered that the larger the volume of the tank, the higher the power consumption will be, respectively. You also need to clarify how many heating elements the model has. If there is only one, and the capacity of the tank is very high (from 100 liters or more), then the device will heat up for a long time and spend a lot of energy to save heat. If there are several heating elements (or one is divided into several parts), then heating will take less time, but the total power of the parts themselves will be greater.
As for the volume of the tank, a 2-4 liter boiler is enough for a family of 70-100 people. For a larger number of users, you should consider purchasing equipment with a larger capacity.
Management
Boilers with a mechanical control system are easy to use and practical – the chance of failure of a toggle switch is much lower than that of an electronic unit. In addition, in the event of a breakdown, replacing it will cost much less.
However, the electronic control system is more convenient. With its help, you can adjust the temperature of the device with an accuracy of a degree, control the operation of the device from a small display, and in the event of a breakdown, many models allow you to perform self-diagnosis.
Dimensions
As a rule, boilers have very large dimensions, which indicates the need to determine in advance the place where the device will be located. Horizontal and vertical mounting options greatly simplify the placement of very massive heaters in the apartment – you can choose a model, the installation of which will allow you to make the most efficient use of the available space.
Economy
As we have already noted, the efficiency of electric boilers primarily depends on two indicators – the volume of the tank and the power of the heating element. It is on them that you should pay attention when buying, if the size of the electricity bill is crucial for you. The larger the tank and the higher the power, the greater the flow.
In this case, you should look at models with an economical heating mode. As a rule, it does not use the entire volume of water or heats it up to the maximum temperature, which saves energy consumption.
Additional features
When buying, check the availability of various security systems for the device. Despite the fact that now most devices are equipped with protection against turning on without water, overheating, etc., there are models without these functions.
In addition, if you are a fan of newfangled “chips”, you can purchase a boiler with the ability to control via smartphone. In this case, you will be able to regulate the temperature, power and turn-on time of the boiler even when leaving home from work.
Checklist for buying the best electric boiler
1. If you decide to buy an electric boiler, decide in advance where it will be installed. Firstly, the device requires a lot of space, and secondly, it needs to be connected without problems to a 220 V outlet or directly to the electrical panel.
2. Carefully choose the volume of the tank. If you have a small family (2-4 people), it makes no sense to buy a device for 200 liters. You will overpay for power, and already at home you will sacrifice extra space for the installation of massive equipment.
3. The volume of the tank, the maximum temperature and the heating rate directly affect the power consumption. The higher these figures, the larger the amount you will see in receipts.
