WATER HEATER: device and characteristic

TEN for a water heater is a tubular electrical device that performs the function of converting a current into thermal energy. It is used both in the industrial and in the household industry as a component part. Self heating of the liquid in our case tubular heaters is carried out by convection, heat conduction and radiation.

Device

The design of heating elements implies the presence of the following tools:

  • Tubes TEN.
  • The filler.
  • The contact rod.
  • Sealant.
  • A metal spiral with a large ohmic resistance.

Together, all these mechanisms are a tubular TEN for a water heater (exactly as indicated in the first photo).

Advantages of using these tools

The main advantage of these heaters in the industrial and household spheres is their universality and safety. They can be used in contact with both liquid and gaseous media, as a result of which they can be used not only on single water heaters. In addition, these tools are able to operate at temperatures up to 800 degrees Celsius, while not afraid of various shocks and vibrations. By the way, thanks to these characteristics, heating elements are widely used in household washing machines. But the most important plus of a tubular electric heater is the safety of its use, which we already noted a little higher. This feature lies in the fact that the TEN (for the water heater "Termex" including) is absolutely not explosive, which allows it to be used in most household appliances.

disadvantages

The main disadvantage of this tool is its high metal consumption and high price, which is explained by the use of metals such as nichrome and stainless steel. It is also worth noting that the TEN (for the Ariston water heater, among others) is practically not repaired when the spiral burns. In addition, these tools have a not very long service life, which is about 5 thousand hours. In this case, the surface of this heater should be cleaned regularly (once every 2-3 months). By the way, TENs, which interact with gaseous substances, serve twice as long - up to 10 thousand hours. However, this does not mean that with a premature failure of the helix, they can be repaired and restored. In fact, the HEAT for the water heater is disposable, so this drawback does not make it the most practical and reliable heater. However, in the sphere of security and universality, it still has no analogues.

Marking

At the moment, there are several markings of these instruments, but specifically, the HEAT for the water heater is indicated by the letter "P", which indicates the possibility of its interaction with liquid substances. Devices that are used to heat gaseous media have a different marking, and depending on the particular type of gas, this can be one of ten notations.
