8 best instantaneous electric water heaters
The most powerful, compact and efficient
Author: Oleg Yasinsky
Many city dwellers are familiar with the eternal problem of seasonal disconnection of hot water. And well, if lasting discomfort lasts only a couple of weeks. It happens that this period is calculated in months. For country estates and at all about heating the water will have to attend independently the whole season or even a year. In such situations, one of the optimal solutions is the use of electric water heaters. The best instantaneous electric water heaters are in our current rankings.
Criteria for selecting a flowing electric water heater
The list of current parameters is not particularly large, but each of them has an important meaning. Competent selection of characteristics is the key to the efficiency of the water heater, its reliability and makes the operation truly comfortable.
Device type
There are two main types of flow models:
- Free-flow. Simple and compact devices, calculated only one point. They are convenient to use with low or unstable pressure in the plumbing system. The best and inexpensive version of the water heater to give or as a temporary source of heating when the hot water is turned off in the summer;
- Pressure head. Often they are also called systemic. They are connected to the water supply system, they work under pressure and can be used to service one or several points of water withdrawal.
Power
The heating capacity of the device and its performance directly depend on this parameter. The optimal value can be determined by the formula:
P = Q x (T1-T2) x 0.073.
Q is the volume of water to be passed in l / min., And T1 and T2 are the inlet and outlet temperatures, respectively.
There is also a simpler method: to get the water heated to about 35 ° C, you need to multiply its planned flow per minute by 2.
Type of heating control system
There are few options:
- Hydraulic. The temperature is regulated by water pressure;
- Electronic. The necessary parameters are set on the display and controlled by the control unit by adjusting the power when the pressure changes.
Equipment
The characteristic is more relevant for low-cost non-pressure water heaters. Variants of nozzles: only tap, hose with a watering can for a shower, tap + shower. Models up to 3.5 kW are equipped with an electrical cord with a plug having a ground contact. For more powerful versions of the cable bundled is usually not provided.

Good running electric water heater at a reasonable price. A power of 6.5 kW can be considered a necessary minimum for normal water heating in the shower. In the presence of "direct" hands, the connection to electricity will not be a problem. |

A very inexpensive instantaneous electric water heater, manufactured from the Scandinavian brand, produced in China, has good technical characteristics for using one water dispenser:
In this case, the water heater provides water heating from about room temperature to 60 degrees - the average temperature difference at the inlet and outlet reaches 35 degrees. If the difference exceeds this value (for example, water is supplied cold from a well or well), the heating will not be as effective. The parameters of the device set a limit on the minimum temperature of the incoming water +16 degrees. Due to its parameters and affordable cost, the heater can be called one of the best low-cost instantaneous electric water heaters in the domestic market. |

The classical flowing electric water heater with a kitchen complete set and with a power of 3.5 kW. Maintains capacity up to 2 l / min. The manufacturer declared the heating temperature to 50 ° C, but in reality it is more likely 30-40 ° C and that provided that the water at the entrance is not colder than 14 degrees. In other words, it is quite convenient to wash the dishes in the summer, but the alternative “shower” equipment is not suitable for everyone. After all, even at the maximum, the water will be only warm and come with a little pressure. Anyway, the device is very popular and, if used properly, is quite reliable. A wire with a plug in stock, although a bit short - 1 meter. It is important to ensure that the outlet used is earthed. Power control is performed using two keys, the temperature is controlled by the mixer tap. Do not forget that Lotus 3.5 is intended only for one point of water intake and is not adapted for work under constant pressure. Main advantages:

They put it to the country house so that warm water was always available in the summer. Hot to achieve is unlikely to succeed, but the dishes, face, hands wash easily. Hooked up the hose with a watering can from the shower - cool, but quite tolerable. |

The universal flowing water heater completed with nozzles the crane and a shower. As well as the models described earlier, the device is free-flow, intended for use only in an open water supply scheme, and only for one point of consumption. Hyundai H-IWR1-5P-UI061 can operate at 3 power levels with a maximum value of 5.5 kW.The manufacturer stated the upper limit of the water temperature at the outlet is 85 ° C, but this is purely theoretical. The real numbers are 30-50 ° C, and the specific result will depend on the chosen mode and head adjustments. The device is able to heat up to 3.6 liters per minute, which is quite enough for a more or less comfortable shower. For management is responsible convenient mechanical knob switch. Safety is maintained by pressure sensors and overheating protection. The heating elements are copper. Main advantages:

Typical mistakes when choosing instantaneous water heaters
Surprisingly, even diametrically opposite reviews of the owners can be found even on the best and most reliable flow electrical. Some are completely satisfied with the device, others are exactly the opposite. And although there is nothing absolutely perfect in this world, and marriage happens to all manufacturers, the lion’s share of negativity is still associated with elementary non-compliance with the rules of operation, installation, or both.
A few examples:
- Non-pressure water heater is used as a system. But its working pressure is limited, and the flask is not designed for a constant or long-term load at all. Therefore, angry type reviews "My device burst, leaks, we flooded neighbors" from the most "cunning" users who wish to get the maximum of opportunities for minimal money are not always objective;
- Water pressure adjustment valve is installed at the outlet, although the instructions clearly state that this is prohibited. Then what is the fault of the device? You just need to carefully read the installation manual;
- Incorrectly chosen section of the electric cable. As a result, the wire and contacts can become very hot, which is fraught with short circuits, fire, damage to the device, not to mention the danger to life and health;
- Wrong choice of parameters. The desire to save often becomes the cause of complaints: it heats poorly, weak pressure, etc.
Finally
Of course, not all decent models are represented in the rating. Some of the devices listed above have alternatives with different specifications or options. Powerful and high-performance instantaneous water heaters powered by a three-phase network (380 volts) are rather closer to professional equipment. They are relevant for installation in new individual houses equipped with special communications for their connection. Our review is devoted to classic household appliances.
The choice of the best instantaneous electric water heater mainly depends on your needs for hot water, the power of the network. And we advise you to pay attention to the availability of service centers of one or another manufacturer in your region.
We wish you a happy shopping!
