The effectiveness of storage water heaters is confirmed by their sales and production volumes. This is one of the best solutions to provide the house with hot water and not depend on the city boiler. At the same time, it is very difficult to decide which company a storage water heater is better, because each of them seeks to beat competitors and produces equipment using its own technical know-how, which improves its characteristics.

To simplify the selection process, we made a review of the most popular manufacturers of domestic-type water heaters (for a private house) and the highest level (increased capacity and volume).

Storage electric heaters - the best companies

The best manufacturers of storage water heaters for the home

The production of domestic water heaters in terms of the scale and complexity of the tasks given is in no way inferior to the manufacture of professional devices. It’s just here that manufacturers of storage water heaters make equipment that is supposed to be used in confined spaces to ensure an uninterrupted supply of hot water for home needs.

AEG - experience and practicality

AEG is one of the few old-timers in the water heater market. It was registered since 1887 and in the process of development mastered the manufacture of a wide variety of equipment. Now it is the largest manufacturer with manufacturing enterprises around the world, and a separate unit, AEG Haustechnik, is responsible for the production of domestic water heaters.

Timberk - The Grace of Technology

All Timberk-manufactured water heaters are designed to withstand heavy use. For this, not only reliable materials and components (stainless steel for the tank and magnesium anodes) are used, but also innovative technologies, according to which the company is one of the leaders in its field.

The "chip" of Timberk water heaters is a microprocessor control system that monitors the occurrence of leaks and prevents the occurrence of excessive pressure in the tank. You can learn about the features of the models from the marking: the shape of the case is F (flat) and R (round), the material is S (stainless steel) and E (enamel).


The main series of produced water heaters:



Series with thin body (d = 29 cm). The working volume of 30, 40 and 50 liters, the installation is only vertical.

Thermex - simplicity and reliability

Since the mid-20th century, the design bureau and the scientific laboratory of the company have been exclusively engaged in the development and methods of improving water heaters. The result of the work is impressive - the company supplies its products to 160 countries, invariably occupying one of the leading positions in the market.

The engineers of the company solve one of the “Achilles heels” of water heaters - corrosion of tanks in places of welding steel sheets - by an innovative method of their own development. This is the technology codenamed G5 - laser welding of metals in a vacuum to avoid air or other impurities entering the joint.Tanks coated with bio-glass porcelain are also used, in addition to the appearance of corrosion, which prevents the appearance of microorganisms.


Models are combined in the following series:



Classic cylindrical water heaters. Tank sizes from 5 to 150 liters, with wall and floor installation.

Ultra Slim

Ultra slim

Ultra-thin water heaters (d = 270 mm) vertical mounting with a capacity of 30 to 50 liters.

Flat Plus.

Flat plus

Flat-shaped water heaters with a capacity of 30-100 l, with microprocessor control and display of operating modes on the LCD display. The material of the heating tanks is stainless steel.

Flat Diamond Touch.

Flat diamond touch

The entire interior is taken from Flat Plus models, but the exterior is polished stainless steel.

Champion (+ Slim).


A separate line of heaters in which the inner walls of the heating tanks are coated with bio-glass-porcelain. The Champion line is made in a steel case with a working capacity of 50-300 liters, Slim are made in a plastic case - they are designed for 10-30 liters.



In terms of characteristics and dimensions, this is the same Champion, but the outer case is rectangular in shape, and the Turbo Boiler function is added to the electronic filling, which can significantly accelerate the process of heating the water.

To save energy, many models use two independent heating elements - if now you do not need the fastest heating, then only one of them works. Management of water heaters is maximally simplified - wherever possible, developers adhere to the principle of "nothing more."

Manufacturers of storage water heaters for large facilities

Autonomy in the supply of hot water and heating is needed not only for private houses and apartments. The owners of large and extra-large facilities, such as, for example, hotels, stadiums, airports and other stores, also think about this. To provide them with hot water, we need devices that are significantly larger than household ones in power and size, which in turn requires the use of non-standard solutions.

OSO Heaters - When Size Matters


The Norwegian company OSO is one of the largest manufacturers of professional thermal equipment - it will be one of the first to advise if it is necessary to choose a storage water heater for large objects. In addition to simply high quality, OSO brand equipment has advantages that not all competitors can repeat:

The volume of the heating tank is up to 10,000 liters. The difficulty here is not even to create a tank of such dimensions - with dimensions of the order of 2x2x2.5 meters, it is necessary to ensure at least uniform heating of the water, plus the maximum possible energy savings (and this is far from all the tasks that need to be solved).

Production of stainless steel heating tanks without the use of anti-corrosion coatings. This is achieved through the use of proprietary plasma arc welding technology, which eliminates the need for fluxes or similar additives, which over time can trigger corrosion.

The longest guaranteed lifetime. The cost of equipment of this size is quite high, so the longer the warranty period, the calmer the buyer. Through the use of proprietary technologies, OSO provides a 10 year warranty on its heaters.

A separate advantage of the brand is experience - for more than three decades, the main tasks of the company's engineers were the development and installation of super-large heating devices. OSO water heaters are already installed in residential and office buildings, cargo and passenger ships, sea oil rigs and other facilities. With such a number of developments, a sufficient number of solutions has already been accumulated, which will significantly accelerate the development and implementation of new ones, if necessary.
