Thermo-electric heater for heating

Thermocouple is a kind of hybrid electric kettle and thermos. The device operates on the same principle as the samovar in the old days. Like an electric kettle, the device brings water to a boil and keeps it hot for a long time. However, like all household appliances, the thermopot sometimes breaks down and needs to be repaired. For the correct selection of the heater for the thermopot and the repair of the thermopot, one must know by its own hands its general structure and the principle of operation.

Thermo button: advantages and disadvantages

Advantages of this unusual device are.

• Significant time savings if hot water is often needed.
• Optimal capacity.
• Economical energy consumption.
• Long working life.
• Ergonomic, thanks to the built-in electric pump.
• The presence of several modes that allow you to adjust the water temperature.
• High degree of safety, as the case does not heat up.

The drawbacks of the thermo-stick include the following.

• High cost.
• Relatively large mass.
• Relatively low power.

Important! The use of this "modern samovar" is inexpedient with the rare use of hot water. But, if you need to boil water often, you will be able to fully appreciate the advantages of this device.

Device

The common set of parts for these devices is the same. They differ from each other only by additional options. All working components of the device are enclosed in a housing. The principle of the thermopot is as follows:

1. There is a stainless steel tank equipped with two heaters for pouring water:
   • One serves to heat water to boiling point.
   • Another - to keep it hot.
2. All electrical parts are properly protected.
3. In the lateral part of the housing there is an engine that supplies water from the tank.
4. Electronic parts perform the function of a time relay when the water is reheated to boiling.
5. There is also a thermal switch, which does not allow the device to overheat.

The general device of the thermo-pin is identical for different instruments. Knowing how the thermopot works, you can quickly find out the cause of the fault and eliminate it.

thermo test algorithm If any deviations in the operation of the device are observed, it means - it is defective and repair of the thermopot is necessary. Consider the order of disassembly and inspection of the device.

Case

It rests on the screws that are on the bottom of the device. To remove the housing, you must unscrew the screws. After that, you should carefully inspect all the details: are there any damages to them.

The thermoswitch is located in the bottom of the housing. Its serviceability is checked with a tester.

Important! If the switch is working, it has infinite resistance.

If a breakdown is found, it remains to purchase a new switch and replace the broken one with a working one.

Pump for heatpipe

You can unscrew it by unscrewing the fixing bolts and disconnecting the supply pipe. Sometimes the device does not work correctly due to the clogging of the pump.

Important! In most cases, the cleaning of the magnet and the impeller is sufficient to ensure that the device has a new life.

The most common problems of

It is not difficult to determine them because different devices operate on the same principle:

• The device does not turn on. It is necessary to check if the power cord is OK, thermal switches, fuses.
• The water does not heat up to a boil, but the button for re-boiling works. If the heatpipe does not boil the water, the thermoswitch, located at the bottom of the device, most likely failed.
• If the situation is "exactly the opposite" - the re-boiling button does not work, the cause is in the electronics malfunction. To find out what exactly triggered the malfunction, you need to look through all the elements of the circuit - starting with the power source and ending with the circuit ground.
• There is no main heating, and the auxiliary one is operating normally. Maybe a heating element or some part of its electrical circuit has failed.
• No water supply. There may be options: malfunction of the pump motor or the failure of an additional heating element. In the latter case, the "on duty" heating will not work.

Repair of simple faults

It all depends on which particular part is out of order. First, you need to study the thermopot circuit, and then start analyzing the cause of the fault:

• Cord. Inside the case there is a shoe for fastening the cord. To check the serviceability of the cable, you must disconnect it and check with a tester for a short.
• Microchip. There are feeding and control elements. The fault can be detected by visual inspection. The failed parts can be replaced with a small power soldering iron.
• Condensers. The broken capacitor looks swollen and is noticeable during visual inspection.
• Diode. This part breaks down quite infrequently. You can determine the malfunction by calling it with a tester.
• Paths of the Getinax Board. If they have microcracks, they can be soldered with tin solder.

Important! If the heater is burnt for the thermopot, then repair, in principle, is possible, but economically unprofitable. The cost of a new heater is commensurate with the price of acquiring a new thermo-stick.

Classification of thermo-cords

The most economical, compact and trouble-free operation is a ceramic device:

• It has three basic temperature modes and a capacity of 1.2 liters. For small family gatherings - this is an ideal option.
• In addition to its simplicity of operation and compactness, the advantage of the device is environmental safety. It is difficult to think of anything safer for health than centuries-old clay.
• The water heats up in a few seconds.

Important! These models are mostly presented by different manufacturers.

Popular models of

• If you are interested in elite home appliances, you will like the model Zojirushi from Japanese manufacturers with microprocessor control and Teflon coating.

Important! This device is equipped with a timer that at the right time will boil water for tea or coffee. This is not just convenient, but also allows you to save energy significantly.

• Thermal cushion "Delta" - a reliable budget option. It can be used not only for heating water, but also as a portable thermos. There is a removable cover, three modes of heating water, as well as a dechlorination function.
• Hotter devices are the best for the average price segment.

Knowing how the thermopot works, you will quickly determine the breakdown and cope with it. However, there are faults, which even a specialist can not eliminate. In this case, you can not replace faulty parts with self-made parts. It is much more reasonable to purchase a new device.
