It is important that all work is carried out by real professionals. After all, as our extensive practice shows, most often electric boilers fail not because of manufacturing defects, but because of design errors and low-quality installation.
Typical problems
Among the most common problems that are typical for electric heating boilers are the breakdown of heating elements, equipment for monitoring and controlling the operation of the system.
If the heating elements fail, restoring the boiler's functionality involves replacing the heating elements or electrodes, depending on the type of equipment.
To prepare for the planned activities, you need to visit a specialized spare parts store. Here you can find the required electric heating element without any problems. You can find out the model of the spare part that will help perform repairs from the technical data sheet of a specific heating unit.
If the problem concerns control and monitoring systems, it is necessary to first take measures to identify the faulty units.
In cases where it is impossible to repair heating boilers by repairing a non-working element, it should be replaced.
Causes of failure
Common reasons for insufficient performance of electrical equipment and its complete failure are as follows:
- untimely maintenance of boilers and unfair operation;
- poor-quality installation and connection of the heating unit;
- incorrect design;
- presence of manufacturing defects;
- natural wear and tear of functional elements.
Replacing heating elements
Troubleshooting an electric boiler by replacing heating elements requires compliance with the following sequence of actions.
To begin with, the boiler is disconnected from the power supply, which is a basic safety requirement and allows you to avoid electric shock. All working fluid is drained from the heating system.
If the heating element mount is in a hard-to-reach place, the electric boiler is dismantled. Next, the wires are disconnected from the heating elements. Each wire is pre-labeled with convenient symbols. The initial order of fastening (zero and phase) is recorded.
Then the fastening elements of the electric heating elements are unscrewed. The heating element is directly dismantled. The special waterproofing gasket is being replaced.
Using an old gasket can quickly lead to leaks when the new heating element is operating.
A working heating element is installed and secured. In reverse order, perform the steps indicated above in the description of the disassembly process. The electric boiler is connected to the network. The operability of the boiler and the reliability of the entire heating system are checked.
Restoring the performance of electrode and induction boilers
Repair of electrode-type boilers occurs by replacing electrodes. The same approach is used here as in the case of repairing heating elements units. However, electrode boilers are more demanding in terms of assembly accuracy.
As for restoring the operation of induction boilers, such heating devices do not have heating elements. Therefore, in case of malfunctions, independent repairs are not possible here.
It is worth noting that the most likely breakdowns of electric heating boilers, as well as the causes and methods for eliminating them, are given in the operating instructions for specific models.
Features of electric heating boilers
Today, electric heating boilers are installed as often in homes and institutions as often as solid fuel systems, as well as gas and liquid fuel systems. Indeed, they are easy to operate, have a fairly high efficiency, and are even safer in many ways than their other “colleagues.”
But at the same time, electric heating boilers also have a lot of design features that simply must be taken into account during their installation and, of course, during repairs.
Today, electric boilers are offered in wall-mounted or floor-mounted versions. The first is less powerful, but more compact and lightweight. Its installation can be carried out even in a fairly cramped room.
But floor-mounted electric boilers have great power and can serve spacious homes and institutions. At the same time, such models are larger in size and have greater weight, and require preliminary hardening of the floor.
Electric boilers can be powered from a conventional single-phase network, or from a more powerful three-phase one. The coolant can be water, oil and similar substances provided by the manufacturer.
Accordingly, all this will need to be taken into account if repair of electric heating boilers of a particular model is required.
When repairing electric boilers, the method of supplying heat energy must also be taken into account:
- with indirect heating. In this case, the heat transfer element is a heating element placed inside the heat exchange device. This option is the most common today;
- with direct heating - here the electrode is placed directly inside the coolant;
- induction models are an effective modern solution based on the principles of electromagnetic induction.
Each of the listed boiler options has its own characteristics, pros and cons. Thus, models equipped with heating elements are among the most expensive in terms of electricity consumption. However, they themselves are quite inexpensive. At the same time, the heating element can collect all the scale from the water - especially if it is placed directly into the liquid. Typically, repairing electric boilers of this model comes down to replacing the heating element.
Induction-type models are economical and efficient. But at the same time they are offered more expensive. And repairing electric boilers of these models is quite labor-intensive and complicated.
Prevention
Compliance with operating rules, along with the implementation of timely preventive measures, largely affects the service life of the boiler. Some manufacturers include an annual service inspection of heating equipment in its cost. If this option is not provided, it is better to carry out preventative maintenance of the boiler in the summer.
Before the start of the new heating season, all unstable functioning elements should be replaced, malfunctions should be eliminated and the system should be checked for operability in advance.
Preventive measures can also include cosmetic repairs of the heating boiler. For example, cleaning air ducts and checking the reliability of connections will help to avoid major problems during operation. Timely, regular implementation of preventive measures along with high-quality installation and proper operation will allow heating equipment to operate trouble-free for decades.
Repair work on electric heating boilers
Our company is often contacted by users faced with the following problematic situations:
- during operation, the boiler makes unusual noises;
- refuses to get involved in work;
- automatic shutdown is constantly activated;
- or vice versa – it doesn’t work;
- The boiler takes a very long time to heat up to the set temperature.
An ordinary user will not be able to independently determine the cause of the problem. To do this, you need to know all the technical features of the unit. Moreover, depending on the model, they can be individual. Sometimes the so-called “reboot” of the unit helps - that is, turning it off and then turning it on again after a quarter of an hour. However, this does not always happen, of course.
Quite often people come to us because their automatic security systems are constantly tripping. It is necessary to carefully inspect not only the boiler itself, but also the electrical wiring in the house. It is quite possible that the problem is hidden there. In any case, our specialist will check the error code being issued and carry out the appropriate repair measures.
Violation of the manufacturer's recommendations during operation of the electric boiler, the use of low-quality coolant, unqualified intervention in the equipment, power surges - all this and much more can lead to breakdowns.

Tips for use
When installing an electric boiler, it is important to pay attention to the nature of the water that is used as the working fluid. If the water is too hard, the heating elements become coated with scale rather quickly. The result is insufficiently efficient operation of the heating system, as well as an increase in the amount of energy consumed by electrical equipment.
To extend the service life of the heating unit, it is necessary to carry out regular maintenance of the boilers, in particular, cleaning the heating elements from scale. However, you can prevent the problem by pouring distilled or soft water into the heating system. A less effective option is to install devices for filtering the working fluid.
The reliability of the electrical system in the home is of particular importance. Outdated wiring is one of the most common causes of electrical equipment failure.
What we recommend
As soon as there is a need to repair the electric boiler, under no circumstances should you try to fix the problem on your own. Modern electric boilers are very complex equipment. Inept actions can not only damage the device, but also cause irreparable damage to your health.
If your electric heating boiler starts to work “somehow wrong,” you should immediately disconnect it from the power supply and call our service specialists. The technician will arrive and conduct a thorough diagnosis of the equipment in order to identify the true cause of the problem. Then they will carry out qualified repairs of the electric boiler with a quality guarantee.
Design features
Regardless of the type, the design of electric boilers requires the following mandatory elements:
- circulation pump;
- copper heating unit;
- fuse in the form of a thermal switch;
- safety valves;
- air valve;
- pressure gauge;
- control panels;
- power control systems.
Common malfunctions of heating devices
One of the main elements of the boiler is the burner, which ensures efficient gas combustion. During operation, carbon deposits from combustion products accumulate on its working surfaces, which leads to a decrease in combustion stability and ignition reliability. Regular maintenance and cleaning can prevent this from happening and prevent more serious problems.
Our technicians most often encounter the following problems with equipment operation:
- the burner does not light;
- poor or slow system heating;
- pressure drop;
- loud noise during operation.
There can be many reasons for this, so professional intervention cannot be avoided. The main ones are unqualified installation and low quality coolant, the presence of contaminants in the system. However, the most dangerous thing is poor electrical wiring, which can lead to malfunctions of the automation and gas leaks.
If you find the slightest defect in operation, contact the service center. Our specialists will promptly come to your home, perform inspection, diagnostics (if necessary) and repair of gas boilers of all brands. At the same time, we offer reasonable prices for all services provided.
Types of faults
