A well-functioning hot water system in a private house is the key to a comfortable stay both in winter and in summer. You must admit that without it it is much more difficult to take a shower or to wash greasy baking sheets.
But even with a high-performance boiler, heated water may not be enough to serve all family members. And then the hot water system is supplemented by an indirect heating boiler, which raises the temperature of the water due to the already installed equipment.
Together with us, we suggest identifying the best indirect storage cylinder: how to choose a boiler, we will find out after analyzing the rating of current models. Among the top domestic water heaters are productive models with a high degree of protection and decent efficiency, designed to serve residential buildings.

Criteria for choosing an indirect heating boiler
With the help of a volumetric tank, which produces heating thanks to an already installed heating system or additionally connected equipment, it is possible to significantly increase the resources of hot water in the house.
More often, BKN is installed near the boiler, which provides heating of water for heating the house, and the DHW circuit is connected. Thus, it becomes part of a community water supply system.
The advantages of the boiler include efficiency, durability, the possibility of introducing into the DHW system with recirculation. Let’s figure out what criteria to consider for choosing a domestic water heater.
Criterion # 1 - tank volume
Useful volume is one of the important parameters that directly depends on the number of residents and the frequency of hot water consumption.
With a properly selected boiler, there will never be a shortage of hot water, and family members can always use a shower, a bathtub and all installed taps at the same time.
For a large water heater, especially a floor heater, it is necessary to provide a special room. Usually this is a boiler room, in which other equipment
When buying a boiler, you can focus on general recommendations for volume:
- 1-2 consumers and 1-2 water taps - 50-80 l;
- 2-3 consumers and 2-3 points of drawdown - 100-150 l;
- 4-5 consumers and from 4 water outlets - 200-250 liters.
It must be remembered that water in small tanks heats up faster, in large ones - longer, and regardless of the size of the tank, the heating rate also depends on the temperature of the coolant, if a heater is not connected.
Criterion # 2 - heating temperature
Water in the BKN never reaches 100 ° C, since it most often takes heat from the liquid from the heating circuit - and there the temperature usually does not exceed 90 ° C.
To control the temperature, a temperature sensor is installed inside the tank, connected to a thermometer. Using it, you can monitor the parameters, and if adjustment is provided, then adjust the desired temperature
On average, the temperature inside the tank heats up to 65-85 ° C. But keep in mind that another part of the heat is lost if the pipeline is long and passes through uninsulated sections, therefore, water can enter the tap with a temperature reduced by 5-10 ° C.
Criterion # 3 - mounting method
According to the position of the housing, the boilers are divided into vertical and horizontal. The former are more popular, the latter can be found much less frequently - these are either small household “indirect people” or huge production models.
At the installation site, all water heaters are divided into floor and wall. Wall mounting is only possible for tanks of limited capacity. Before buying, be sure to make sure that your wall will withstand the installation of equipment, given the weight with water.
The vertical shape of the water heater is more convenient for floor mounting - the base takes up much less space, and connecting and servicing is much easier
In general, among BKN there are most of all vertical models with floor standing, less often with universal installation. From a safety point of view, outdoor options are more reliable.
Criterion # 4 - fabrication material
The material from which the external and internal tank is made affects the durability and life.
To protect the inner surface from corrosion, various types of coatings are used, including:
- stainless steel;
- glass ceramic;
- enamel.
The first option is the most preferred, high-quality food grade steel used to protect expensive models. The enamel cracks due to constant temperature changes, and the glass ceramics deposited by the dry method are not inferior to the steel surface.
The outer casing is made of stainless steel, cheaper metal or heat-resistant plastic.
The metal of the outer tank is coated with heat-resistant paint, which serves throughout the life of the tank. If the paint peels off, and the metal under it rusts, it is better to replace the boiler in a timely manner with a better one
One of the successful options for floor installation is a water heater made entirely of stainless steel. They are heavier and more expensive, but as much as possible protected from corrosion and leaks.
Criterion # 5 - connection of a heating element
The introduction of an additional energy source is necessary in some cases:
- if the heating system, centralized or autonomous, is turned off for the warm season, maintenance or repair;
- if the temperature of the coolant is unstable and requires support;
- if the temperature from the heating circuit is insufficient.
Before buying, be sure to check if it is possible to connect the heater: some models do not have it, others are designed to install 1-2 heating elements. For them, special nozzles or inspection holes are provided.
