TOP 5 electric boilers for main and backup heating

The Vaillant eloBLOCK VE 9 electric boiler is designed to create an efficient and comfortable heating system with the ability to be precisely adapted to a room of about 68 m². The model has optimal power, so connection requires a standard 230 V power supply. A generator can be used as a backup power source. When connecting an indirect heater, the user receives hot water supply, which is also possible in the summer thanks to the design of two independent heating elements. In this case, a less powerful 3 kW version is used, and for full heating, a second 6 kW version comes into play. Using an electric boiler, you can create a heated floor system with a comfortable and safe temperature.

The Vaillant eloBLOCK VE 9 boiler is equipped with protection against overheating, freezing and disruption of water circulation in the circuit. The work is controlled electronically in automatic mode. The user only needs to set a comfortable temperature level using the control buttons and display. An eBus is provided to expand the capabilities. It allows you to connect additional modules for remote control, configuration and diagnostics via the Internet, automation of heating based on weather conditions. It is worth noting good maintainability. The manufacturer offers all the necessary components, the replacement of which will not cause difficulties, unlike gas equipment. With a two-tariff electricity meter, maximum efficiency is ensured.

The Protherm Skat 9KE/14 electric boiler copes well with heating apartments, private houses, and commercial properties as an individual system or in combination with gas or solid fuel types. The manufacturer has provided the possibility of cascade connection using an external circulation pump. This will make it possible to create efficient integrated heating of houses with a large area and provide variability for the autumn-spring and winter periods. The electric boiler’s own power is enough to heat about 72 m², and provided that heat loss is minimized (facade insulation), it can be the main source of heat. This is especially true for holiday villages and rural areas where gasification is not provided. If there is no separate 230 V electrical wiring of the required power or there is a temporary blackout, you can use generators or solar panels.

The Protherm Skat 9KE/14 boiler is equipped with a smart electronic unit that automatically controls the system. All initial settings are easily performed using buttons and the display. Information about possible malfunctions is also displayed there. The set of safety measures includes protection against overheating, freezing, pressure drop, excess load on the electrical network and disruption of the water supply. The eBus helps expand the functionality of the boiler using additional devices. This will allow you to control the heating remotely and create an operating schedule based on internal or weather-dependent sensors. Protherm Skat 9KE/14 can be easily repaired by replacing components. This does not require complete disassembly and the help of specialists.

The Willer PT207 VOLT WF electric boiler offers the user advanced functionality and high-quality technical solutions that will help create a main or backup heating system at an affordable price. The heat exchanger is made of aluminum-magnesium alloy by casting, so it is seamless and durable. It contains a patented heating element that provides dry and safe heating. This allows you to avoid the appearance of scale and reduce the efficiency of the heating element, eliminating the need for scheduled maintenance.

The boiler is compatible with indirect heating water heaters to create a hot water supply circuit, as well as heated floors. It has average power, which is enough to heat a house, apartment, or office with an area of about 60 m². Connection to single-phase (230 V) and three-phase (400 V) power supplies is available, as well as backup power supply from generators.

The electric boiler comes with a Wi-Fi module for remote control via a proprietary application. Operating parameters are displayed on the display, and control is carried out using touch buttons. The electronic unit controls the functioning of the entire system, preventing overheating and freezing of the coolant.

The Teknix ESPRO 7.5 kW electric boiler is distinguished by a number of technical solutions to increase service life and efficiency. Here, 6 separate heaters of 1.25 kW are used, and their activation for heating the coolant is carried out alternately, which ensures uniform wear. The system itself selects the number of heating elements that are needed for effective operation based on the comfortable temperature conditions specified by the user. The Wilo-Yonos PARA pump with frequency control automatically regulates water pressure, ensuring stable circulation and compatibility with indirect heating boilers. The control unit is located in a protected housing on top, which eliminates the risk of damage in the event of a leak inside the housing. The front glossy glass panel is equipped with a touch screen with which you can quickly change operating parameters. All settings are saved in memory and will not be reset when the power is turned off. The boiler output is sufficient for residential and commercial premises with an area of about 60 m². To connect, you will need a three-phase 400 V line or a single-phase 230 V line. In emergency cases, you can use the energy of gasoline generators.

Teknix ESPRO 7.5 kW is equipped with a Wi-Fi module and the TEKNIX Smart boiler application for remote control via a smartphone. The presence of a weekly-daily programmer allows you to accurately set the on/off intervals so that heating coincides with the owners returning from work. This will allow you to save electricity during the day and take advantage of favorable night prices when using a two-tariff meter. Two temperature control options are available using internal water and external air sensors. The user independently determines which type of setting is suitable for the room.

The electric boiler is protected from overheating, freezing, excess water pressure and circulation problems, electric shock and the appearance of legionella bacteria.

The Thermex SKIF 5-12 Wi-Fi universal double-circuit boiler is compatible with different types of heating systems and is suitable for heating rooms up to 96 m². 4 power levels are available (5, 8, 10, 12 kW) to adapt to the quadrature, wiring options and required climatic conditions. The maximum power is limited manually on the control board, and subsequent control is provided by the electronics, automatically adjusting the heating to achieve an efficiency / economy balance. Two circuits are responsible for heating and hot water supply. An advanced electric boiler can be easily integrated into a heated floor system, and the corresponding mode limits the temperature at 60 °C to prevent excessive heating and discomfort upon contact with human skin. Hot water supply is also limited to 60 °C. The aluminum-magnesium heat exchanger has increased thermal conductivity and anti-corrosion properties.

The electronic unit prevents overheating, freezing and disruption of coolant circulation in the system, maintaining the integrity of the components. Error codes are displayed on the display, allowing you to accurately determine the malfunction. The electric boiler can be used in apartments, private houses, offices and commercial buildings with single-phase (230 V) and three-phase (400 V) electrical wiring, and can also receive power from street generators of the appropriate power.

Thermex SKIF 5-12 Wi-Fi is a smart boiler that supports remote control via the Thermex Home app. The Wi-Fi module allows you to quickly integrate heating equipment into the Smart Home system, and the built-in programmer fully automates the operation of the boiler, activating heating at specified intervals. The user receives additional savings with a two-tariff electricity meter.
