With the advent of the summer months, most apartment buildings in Russian cities experience massive hot water outages. It is quite natural that this creates quite serious difficulties for residents — there is nowhere to wash themselves, bathe a child, have to heat water in pots, and so on. Manufacturers of household appliances went to meet consumers and developed a very convenient and economical device — a flowing electric water heater.
These products immediately turned out to be to the liking of most users, so these devices literally flooded the market. Unfortunately, choosing the most suitable model from the available variety is not as easy as it might seem at first glance. In this regard, we decided to rank the best electric instantaneous water heaters of the year. However, here we will not only analyze the performance characteristics of specific models that are included in this review, but also give some useful tips on choosing this equipment. Let’s start with this.
How to choose the right instantaneous electric water heater?
These products have a not too complicated device, they include a body made of metal or plastic, where a small water tank is located. It also has a heating coil or heater. Budget models have one or two heaters. Unfortunately, they quickly overgrow with scale, but if necessary, they are very easy to change for new ones. Products that are more expensive have a heating coil that is placed in a hollow copper tube. Such devices do not respond well to air bubbles and air locks that may form in the tank.
If there is a need to equip several points of water analysis at once, then for this it will be necessary to provide a good flow and decent pressure. Non-pressure heaters, capable of operating even at low pressure, are able to serve just one single tap. Heating is provided almost instantly, and electricity is consumed exclusively during the operation of the heater itself.
These models have small overall dimensions, which is very important for rooms characterized by small free space. The heater can be installed both in the immediate vicinity of the tap, and at a decent distance. One of the main criteria that directly affects the choice of such equipment is its power, expressed in the volume of water that this device is able to warm up per unit time. If the family is small, and its main needs are showering, cooking and washing dishes, then products that can produce up to 5 liters of water in one minute will be enough. In this regard, it is advisable to purchase products whose power will be in the range from 3 to 6 kW.
Despite the fact that similar products have a simple design, all manufactured products can be divided into two groups — hydraulic and electronic. Hydraulics usually don’t cost too much. A step switch acts as a control element here. Thanks to the electronic control, you can set not only the desired temperature, but also the desired level of heating. Elite models have microprocessors and sensors that can respond to pressure and temperature changes.
When choosing models to include in our ranking of the best electric water heaters in 2022, we were guided by all the points above, as well as taking into account user reviews and product value for money. We hope that after carefully studying the review, you will be able to choose the best water heater for yourself, the performance of which will be quite enough for all households.

4. Stiebel Eltron DHC-E 12
This model has appeared on the market for quite a long time — about 5 years ago, and during the time it was on store shelves, several modifications were developed that differ from each other in such indicators as power, water tank volume and consumption electricity. Thanks to this, the consumer can receive from 5 to 11 liters of hot water per minute, which allows you to connect this device to several water points at once. This water heater is characterized by a rather high cost, which is not too surprising, since it was developed by engineers from a well-known German company. The control here is exclusively mechanical, there is a built-in thermometer, a liquid crystal display, as well as a heating temperature limiter. / This allows you to use the device completely safely, since it will not warm up above the specified threshold, so the owner will never get burned.
The starting pressure is quite decent, as a result of which the water consumption increases slightly, but not too critical. The internal wiring is all copper and has a good level of safety margin, so the user does not have to worry about overload. There is a system that reliably protects against significant voltage drops.
Advantages:
- There are several modifications of different power — you can choose the optimal product for water consumption;
- There is a system that limits the maximum heating temperature;

In turn, this ensures a fairly long service life of the heating element and will not require replacement. If any part needs to be repaired or changed, then finding it on sale will not be the slightest difficulty.
Despite the fact that the model is characterized by decent power and small size, it is notable for its low cost. In addition, there is a water filter that can also increase the life of this device. The control here is mechanical, so it is unlikely that it will be possible to set the temperature with an accuracy of tenths of a degree.
Advantages:
- Decent power of this device;
- Compact overall dimensions;
- The output is hot water, regardless of pressure;
- High quality workmanship.
Flaws:

1. Electrolux NPX6 Aquatronic Digital
Finally, we got to the leader of this part of the review. This product combines compact dimensions, decent efficiency and high performance — this parameter was achieved through the use of high-power spiral heating elements. They are made from high quality polymer coated stainless steel. Scale on the heating elements will accumulate very slowly — about 5 times slower than other models. The device has touch-type buttons, as well as a very informative LCD-type touch display. Manufacturers decided to hide the screen under the control panel, so it becomes noticeable when setting the temperature. The water heater has an electronic type control system, thanks to which it is possible to adjust the degree of water heating with an accuracy of one degree.
The performance of this device reaches 2.5 liters per minute, and the efficiency of the order of 95% is a very high indicator for products of this type. During operation, the spiral of the heating element vibrates a little, so even the smallest particles of scale fly off it. Thanks to this, it is possible to significantly increase the service life of not only the heating element itself, but the entire heater. The device is equipped with a very reliable thermostat that provides protection against overheating — the device will turn off if the water is heated to a temperature of 70 degrees or higher. The design is quite elegant, so this device will organically fit into the interior of any room.
Advantages:
- Compact dimensions;
- Heats water superbly
- There is an automatic diagnostic function;
- There are no restrictions on the number of liters consumed.
Flaws:
- Consumes a decent amount of electricity;
- Be sure to lay a separate line from the shield.
