Why can a boiler be shocked?
Owners of water heaters are often faced with such an unpleasant phenomenon as an electric shock. Most often, ordinary people have no idea what to do in this situation. Why does the water heater strike with electricity, and is the defective device dangerous? Yes, it is dangerous! Further operation of the boiler carries a health risk. The owner should call a specialist or replace the device with a new one.
Water punching
A completely serviceable and recently bought tank for heating water suddenly begins to strike the wearer with an electric discharge upon contact with a liquid. It feels like light shots on fingertips, accompanying a person when touching the mixer. It becomes clear that rinsing hands with electrified water is a painful procedure. Each time, opening the tap, the owner of the boiler will be afraid.What could be the reason for hiding?
- The device was not grounded during installation. Carefully follow the installation of the newly acquired boiler: the lack of grounding can lead not only to injury, but also to premature breakdowns.
- Malfunctions of heaters in the tank, more specifically, the destruction of the protective shell of the element that protects it from contact with liquid.
- Incorrect power connection. This could be due to improper installation.
What should be done in this situation? If possible, refuse to use the tank before the arrival of a specialist. Only after carrying out a professional technical inspection can a conclusion be drawn up, and a sequence of actions can be drawn up to eliminate the problem.
Breakage TENA
One of the most common causes, in which water beats up with current, is a significant destruction of the protective layer of the heating element. This detail provides the performance of the entire system, but has a low power. Externally, the element looks like a simple metal tube. The main task of the heating element is to supply the electricity necessary for boiling water. To perform these functions, it has a special nichrome thread. Possessing high conductive properties, this material provides the necessary heating of the liquid.
The work of the heating element takes place in critical conditions. The constant moisture that surrounds the heating element increases the risk of corrosion, and, consequently, the formation of scale. A combination of factors leads to wear of the heating element and the exposure of the nichrome thread. Being one of the best conductors, the water with which nichrome interacts can be electrocuted when touched.
To fix this damage is quite simple. For this you need:
- disconnect the boiler from the mains;
- drain all the water from the storage tank;
- dismantle the spent heating element and install a new part.
Selecting spare parts, it is necessary to pay attention to their manufacturer. The ideal option would be to buy parts from the same company as the tank itself. Experts do not recommend purchasing cheap low-quality counterparts.
Network connection errors
In rare cases, the root of the problem may be negligence when mounting the device. The water heater will start to beat with a current if the master incorrectly connects it to the power supply.As a rule, the problem is detected at the stage health checks, but in some cases an error is detected after a certain time. Removing the problem will help re-connect the wires connecting the tank and the electric meter.
It is very important to follow all the rules when installing and using a home appliance. Careless handling can lead to serious damage.
A malfunction can also occur if the wiring is cheap or low quality. The period of its operation is quite limited, and it can be used only as a temporary replacement. High cable wear not only creates the danger of electric shock, but can also cause short circuits. For these reasons, experts urge not to save on the quality of the wires.
Punching the body
If the use of a boiler leads not only to a current blow through the water, but also to the electrification of the case, it is necessary to immediately de-energize the device and abandon its operation until an expert opinion is obtained. Only after repair will the safe operation of the device become possible.
In this case, can help proper grounding. Experts say that in this way several drawbacks are eliminated at once:
- the danger of electric shock disappears;
- over-consumption of electricity is reduced;
- reduced formation of corrosion on the heater.
Additional security can guarantee RCD installation. Professionally installed grounding removes voltage from the surface of the device. Without a protective shutdown device, this process leads to the destruction of the case, faults in the heating element, and false alarms of the electrical machine.
Summing up, we can say that if the tank hit the owner at least once with a current - this is an occasion to think about checking it out. A good specialist will be able to give an expert opinion and, if necessary, fix the damage.
