How to choose a 10-15 liter water heater?
The key parameter when choosing a water heater for most users is the volume of the device.
But, if you have decided on this criterion and decided to buy a 10-15 liter boiler, you should pay attention to other parameters:
- Shape and material of the case . Its cost directly depends on the shape of the water heater. Most models are cylindrical, but there are also more expensive flat rectangular devices that take up minimal space. The body of the device can be steel or plastic. Devices of the first type are more reliable and more expensive.
- Tank material . The tank can be enameled or stainless steel. The latter option is better, since stainless steel has increased resistance to corrosion and mechanical damage.
- Management . The simplest models provide only a rotary control and a dial that displays the water temperature. More advanced devices have an electronic control panel with a small display.
Cumulative
A storage type water heater is especially convenient because it always has a supply of hot water. In addition, it can be heated to high temperatures, which flow-through models cannot do.

The best manufacturers
For most users, not only the characteristics of water heating devices are important, but also the manufacturers. Reputable brands not only inspire trust, but also locate their service centers in all major cities.
Ariston
The Ariston brand belongs to the Indesit Company concern, founded in Italy in 1930. Today it is one of the largest manufacturers of household appliances in Europe and the undoubted market leader. The concern includes brands - Ariston, Indesit, Hotpoint and Scholtes. The Ariston brand produces a number of large household appliances - washing machines, dryers and dishwashers, water heaters, cookers, refrigerators, etc. The company has several manufacturing plants in different countries, including China. All factories maintain strict quality control of their products.
Electrolux
Electrolux is a brand of a Swedish manufacturer of household appliances, founded in 1919. Today it is not just a company, but an entire corporation called Electrolux Group, which unites several smaller companies. The products of this manufacturer belong to the middle and high price segment. The product line includes a wide variety of small and large household appliances, including water heating devices. The company is distinguished by innovative ideas, which it often implements into its products.
Gorenje
The Gorenje company was founded in 1950 in Slovenia and throughout its development has become one of the top ten manufacturers of household appliances in Europe. Having started its activities in the small town of Gorenje, the company was able to conquer the world market by absorbing some small production facilities. Already in 200, the Gorenje concern organized several additional production complexes and factories in South-Eastern Europe. The company acquired the Czech board factory Mora Moravia and the Dutch manufacturer of household appliances Atag. For several decades, Gorenje has been producing reliable, high-quality water heating devices for domestic use.
Thermex
Water heaters under the Thermex brand first appeared on the Italian market in 1949, but they were produced by the Lorency Vasco plant. Later, the production became part of a single corporation called Thermex, specializing largely in the production of high-tech water heating systems. In 1995, products under this brand appeared in Russia, when the company's central office opened in St. Petersburg. In 2007, along with a large number of retail outlets, the first automatic factory was opened in the Leningrad region. Today there are 27 enterprises, 104 branches and representative offices in the Russian Federation, CIS countries and far abroad.
Rules for selecting a horizontal boiler
First of all, you need to plan the area of the kitchen or bathroom where the water heater will be hung on the wall. For a horizontal layout this is especially critical. The useful area of the walls, as a rule, goes along this axis. If the ceilings in the house are high, there will be no problems with the location of the vertical boiler.
For similar reasons, popular models of horizontal boilers are made with a flat tank. Another reason is that it’s easier to balance the center of gravity. In the descriptions below, all models are considered in flat format.
The empirical table for water heating times remains approximately the same (different manufacturers state rather different figures), with the exception of the uniformity of heating.
| power , kW | Time heating |
| 0,75 | 2 hours 20 minutes |
| 1 | 1 hour 45 minutes |
| 1,5 | 1 hour 10 minutes |
| 2 | 53 min. |
| 3 | 35 min. |
Advice. The most popular both in price and in terms of cleaning efficiency are 1.5 - 2 kW models. More is too energy-consuming and expensive. Less means a long time to wash, and a kilowatt heating element is not particularly cheaper than a two-kilowatt heating element, either in “dry” or “wet” versions.
