13 best storage electric water heaters

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

To organize water heating in a private house or in the country, various water heaters are used. Residents of high-rise buildings also resort to them, wanting to stay in comfort during preventive outages of the centralized hot water supply for several weeks. One of the most popular are storage electric models. Our experts have prepared a rating of such water heaters, which will help you make your choice.

How to choose an electric storage water heater

When choosing a storage water heater powered by the network, or as it is also called a boiler, we advise you to pay attention to the following parameters:

1. Storage device volume. The models are available in capacities ranging from 30 to 300 liters. The calculated value is 30-50 liters per person.
2. Installation method. Water heaters are floor-standing and wall-mounted. The former are easier to install, but take up useful floor space, the latter can be placed at a convenient height, but this requires more time and the presence of a solid partition (walls made of plasterboard or gypsum will not work).
3. Tank material. A steel tank covered with enamel will come out cheaper. A more advanced option would be glass ceramics. The most durable is a stainless steel container, but the price of such a water heater is also high.
4. Heating element type. Electric boilers heat the liquid with heating elements. It can be 'wet', that is, it has direct contact with water, and 'dry', isolated in a sealed flask. The former have a higher heating rate, but the service life is shorter. The second is the opposite.
5. Control type. The simplest here is the mechanical type – a relay that controls the heating power and turns off when a certain temperature is reached. Electronic control more precisely maintains the set temperature, has anti-freeze protection functions, a pleasant digital display and other settings that make operation more comfortable.
6. Heating element power. The indicator varies from 1500 to 6000 W and affects the heating rate.

Our rating contains 13 storage devices for water heating, which are distinguished by good characteristics and have collected many positive reviews. Before moving on to the review, let's note why this type of water heater is better than an electric instantaneous one.

Which water heater is better instantaneous or storage

Boiler type	Advantages	disadvantages
Cumulative	+ Long-term retention of heat (even with a power outage) + Economical energy consumption + No need for a separate electrical line + Stable flow temperature	– It takes time to warm up the volume – Take up a lot of space – Heavy during transport – High price – Complex installation
Flowing	+ Low weight + Easy installation + Heats only the water that is currently in use + Low price	– Consumes more electricity – Need a wiring with a cross section of 2.5-3 mm2 – Dependences of the heating force on the temperature of the incoming stream
