to contents ↑Varieties of water heaters
When choosing an electric heater for water in the house, you should know that, depending on the basic principle of operation, these devices are divided into the following categories:
- Flowing equipment.
- Storage devices.
Each of these types of equipment has its own advantages and disadvantages, which affects its functionality.
Instantaneous water heaters
The main element of flowing water heating equipment is located inside the heater. This heating system includes a copper pipe with a pressed-in heating nichrome spiral.
Important! The design of the heating element is not afraid of the formation of air jams and is characterized by a long service life.
Flowing boilers do not have a storage tank, because their functional purpose is to heat the entire volume of water passing through them. However, it should be borne in mind that for heating significant volumes it is necessary to choose high-power equipment.
Important! In order not to limit family members in the amount of hot water used, it is recommended to install a flow-type boiler, the power of which is from 4 to 27 kW.
pros
The main advantages of water heaters of this design are the following properties:
- have the ability to provide the user with the necessary amount of water at any time;
- do not require regular maintenance;
- has compact dimensions, which allows its installation in a room with a limited area.
Important! If you plan to choose exactly this type of equipment, leave a note on our article about how to connect a instantaneous water heater.
Minuses
However, perfect equipment does not exist, therefore flow-type boilers have several disadvantages:
- To install such a device, it is necessary to have centralized water supply systems with a constant pressure;
- presence of stable power supply in the room;
- can provide only one point of water intake with water.
Important! Before buying a instantaneous water heater, it is necessary to consult with a qualified electrician, because not every wiring can withstand the voltage provided by this equipment. It should also be taken into account that such devices are not suitable for installation in “stalinkas” and “Khrushchevs”.
Accumulative water heaters
According to the structure and principle of operation, the storage water heater resembles a thermos, which has the function of heating the water. Initially, this device accumulates the required volume of water, after which it carries out its heating and maintains a given temperature regime.
Important! Due to the installation of a storage water heater, you will provide your family with a large amount of hot water at relatively low loads on the electric network.
pros
Such equipment is characterized by the following advantages:
- the device can perform the functions assigned to it with not the best pressure in the central water supply network;
- energy efficiency when heating water to a temperature of 80 ° C;
- the ability to provide hot water to several water points.
Important! The average power of storage heaters is 2 kW, which does not pose a threat to the wiring.
Minuses
Like any technical device, storage boilers have a number of disadvantages, the most significant of which are the following:
- the need to conduct maintenance of installed equipment every 6 months;
- water heating occurs within 1-2 hours;
- the ability to process only a certain amount of water.

Practical advice for the buyer
When choosing a home electric water heater, you should, first of all, pay attention to the following equipment characteristics.
Dimensions
To obtain the optimal amount of hot water for domestic needs and in order to maximize the efficiency of operation of water heating equipment, a boiler of the appropriate size should be chosen.
Important! Do not forget to take into account the features of the room where you plan to install an electric water heater, so that after the purchase there are no problems with the choice of its location.
Energy efficiency
To ensure savings in energy consumption before buying equipment, check with the seller the degree of rationality of energy consumption of your chosen device.
Operating expense
Experts recommend that before buying a water heater for the home, to clarify the annual operating costs of the device and compare this indicator with other energy-efficient models.
type of instalation
Depending on the volume of the room for the boiler and personal preferences, you can purchase a device of one of the following types:
- for horizontal installation;
- for vertical installation;
- universal equipment.
Tank Material
Different models of domestic water heaters may have a stainless steel or enamelled steel tank:
- Stainless steel is more preferable for its operational characteristics.
- Enamel - will cost less.
The presence of a magnesium anode inside the device
This chemical element protects the boiler from internal corrosion damage. If the model of the water heater you like does not imply the presence of a magnesium anode, it is recommended to choose a more practical and reliable unit.
Storage tank volume
The expediency of purchasing new equipment to obtain a stable volume of hot water will depend on how correctly you decide on these parameters.
This parameter is important only for cumulative models:
- The optimal tank capacity is 100-150 liters. This will be enough for an opportunity to take a shower to a family of 2-3 people, without a lack of water in the kitchen.
- In spacious private houses where a family with a large number of members lives, you can choose an electric water heater with a volume of 200 liters.
- And for giving - 50-80 liters are enough.
Important! In flow models, the heating rate and volume of water are determined by power. For example, models with power values of 3.5-6 kW are popular - this is enough to service a kitchen sink, a washstand in the bathroom, and fine washing. But for taking a shower - you need at least 8 kW.
Thermal insulation quality
This parameter is also important for storage water heaters.The best are those that have a double system of tank walls with an additional gasket of insulating material. They may be, for example, polyurethane foam.
Important! Each high-quality electric water heater requires the following structural elements - a control unit, a heater, a magnesium anode and a thermostat. The most economical are devices with a thermostatic device of capillary or electronic type.
Overview of brands and manufacturers
An extensive range of equipment from various manufacturers is presented on the modern market for water heaters. Boilers differ among themselves not only in price and external performance, but also in functionality, workmanship, reliability, energy efficiency and many other qualities.
Important! The following points are also important for safe operation of the equipment:
