Homeowners can guarantee the smooth and efficient operation of their electric boilers by being aware of these common problems and knowing how to fix them.

Lack of heat or hot water is one of the most common issues with electric boilers. There are a number of potential causes for this, including a broken thermostat, an inadequate heating element, or sediment or limescale accumulation in the boiler’s tank. It’s crucial to make sure the thermostat settings are set correctly when dealing with this problem. Next, check for damage or wear and tear on the heating element if the thermostat is functioning properly. To get the heating element operating properly again, it might occasionally be necessary to clean or replace it.

Leaks are another frequent problem with electric boilers. Broken seals in the boiler system, corroded pipes, and loose fittings can all cause leaks. Leaks must be fixed right away to avoid potential safety risks and water damage. Start by looking for any obvious leaks in the pipes surrounding the boiler. Minor leaks are frequently fixed by tightening loosened fittings and changing harmed seals. To repair or replace the damaged parts, professional assistance might be needed if the leak continues or seems to be coming from a corroded pipe.

Furthermore, pressure fluctuations can be a problem for electric boilers. High pressure can unnecessarily strain the boiler and its parts, while low pressure can lead to decreased heating efficiency and insufficient hot water production. Before taking any action regarding pressure problems, homeowners should make sure that the boiler’s pressure gauge is reading within the recommended range. The boiler’s filling loop can be used to top off the system with water if the pressure is too low. On the other hand, it might be required to release excess pressure from the boiler’s relief valve or tobleed the radiators if the pressure is too high.

In conclusion, even though electric boilers have a lot to offer in terms of home heating, they are not impervious to issues and malfunctions. Homeowners can maintain dependable and efficient heating systems by being aware of common problems and knowing how to diagnose and fix them. Homeowners can guarantee that their electric boilers continue to provide warmth and comfort for many years to come by promptly resolving any issues that may arise.

Causes of breakdowns of electric boilers

In places without a main gas supply, electric boiler units are essential for personal heating.

However, during boiler operation, malfunctions may arise from component wear and tear or other causes that can only be fixed by fixing electric heating boilers.

Malfunctions can be caused by a number of external factors:

• low consumer quality of the coolant, which leads to the appearance of scale and harmful salt deposits on the inner surfaces of the heat exchanger;
• voltage surges in the electrical network, power failure;
• violation of technological installation: automatics, piping and building structures;
• Atmospheric circumstances and lightning charge accumulation, negatively affecting the electrical control circuitry.

In addition, low-quality equipment purchases, structural element wear and tear, and mechanical flaws from falls should be considered as potential causes of electric boiler malfunctions.

The latter are also thought to be indicators of subpar performance and disregard for the guidelines when using heating appliances.

The following categories of violations are exclusively internal:

• Failure of the automatic system of control and regulation of the heating process;
• constructional faults of the basic elements of the boiler unit: burner, circulation pump, air vent and strainer.

Main faults and repair methods

Regardless of the kind of failure, you must first establish the parameters of the power supply system and the medium pressure in the water supply system before you can proceed with repairing the heating boiler unit. The internal thermal boiler, automatic control, and heating element malfunctions are among the most frequent issues that arise when fixing electric boilers.

HEATING ELEMENTS

By replacing the heating elements in an electric boiler, malfunctions can be eliminated, and strict manufacturer guidelines must be followed. Only the service center is authorized to carry out repairs on Protherm boilers that are still covered under warranty.

In order to ensure its own safety, the boiler unit must first be disconnected from the electrical grid. This eliminates the risk of electrocution.

The repair staff’s next required task is to empty the liquid out of the internal boiler circuit. Simultaneously, shut-off valves at the boiler’s inlet and outlet disconnect the water, negating the need for a drain in the home heating system.

If the heating elements are situated in difficult-to-reach areas, disassemble the boiler’s internal components. The wiring from the heating elements is then severed. Phase and zero of the initial connection system are predetermined.

The electric heating element mounting components are then unscrewed. It replaces the specifically made waterproof gasket. When operating a newly installed heating element, using old packing is likely to cause leaks to appear quickly.

A defective heating element is installed and adjusted. The steps outlined in the disassembly process are carried out in the opposite order. The power grid is linked to an electric boiler. The heating system’s safety and operability are monitored and controlled.

Boiler repair involving electrode variety is accomplished by replacing the electrodes after a similar boiler disassembly procedure. Electrode boilers are also the most punctual in their assembly requirements.

Concerning the restart of induction boiler units, individuals are unable to perform self-repairing work on them due to the absence of heating elements in these types of devices.

Safety automatics

The following are the most common reasons why electric boiler control unit malfunctions:

1. Breakdown of the remote control of the boiler modes.
2. Failure of programs, which may have happened during transportation or installation.
3. Board malfunction.
4. Erroneously set program code mode after assembly is completed.

Criteria for a malfunctioning control unit:

1. In the presence of electricity, the boiler unit does not heat water, which indicates an incorrect adjustment of temperature regimes.
2. Blown fuses and malfunctioning of the network controller.
3. Failure of electronic boards.

Only specialists from service centers are capable of correcting the most recent failure.

Heat exchanger

An air lock in the heating system or a malfunctioning coolant circulation pump could be the cause of the boiler’s internal boiler not heating up. Low heat transfer in the boiler also suggests that limescale has clogged the heating surfaces.

You can remove air locks on your own by using the air vent. Only in service centers is it possible to completely eliminate circulation pump failure.

Who should be in charge of repairs

On the Russian market, domestic electric boilers made in other countries are adequately represented. For their assistance, service companies are set up within the manufacturer’s top distributors’ branches, or they can be built upon the foundation of assembly and dealer businesses.

Prior to signing a contract for warranty service, the equipment owner must ensure that the service provider has all the paperwork required to verify that it is authorized to perform design and adjustment work in addition to warranty service for heating boilers.

• licenses for design, installation and adjustment work on gas equipment;
• certificate from the manufacturer with authorization to perform assembly, adjustment and maintenance services by trained personnel;
• protocol of certification of employees on safety rules.

The work of the service provider must be grounded in both state regulations (SNiP, GOSTs, and fire safety standards) and boiler equipment manufacturer requirements, as detailed in operation manuals, certificates, and other technical documentation.

The warranty period typically begins when commissioning procedures completed under a contract that outlines the general specifications and terminology of the work to be performed are completed.

The warranty service contract also outlines the parties’ rights and obligations, as well as the cost, method, contents, and timing of routine maintenance.
