What is a water heater with a dry heater?

Modern manufacturers often equip manufactured water heaters with a dry heater. This element extends the life of the unit and also simplifies its use.

What is a dry PETN, and what features are typical for water heaters with such a component, this article will tell.

Tan is a thermoelectric part. In the water heater, this element is in a special flask. Thanks to this “isolation”, contact with the water is excluded. This design is safer to use, therefore, is very popular.

In order to better understand what a water heater with a dry heater is, it is necessary to consider in detail what its features are.

Standard constructions of such units consist of the following elements:

• hollow bent pipes of copper or stainless steel;
• spirals of non-chrome filament inside;
• an insulator, which acts as a heat-conducting substance (it can be magnesium oxide or quartz sand).

Dry PETN is in an insulating ceramic flask with high strength. Often its body is made from magnesium silicate or inorganic steatite, but never use metal.

The process of direct heating takes place through this flask. The tubular part itself does not come into contact with the aqueous medium at all, and therefore it serves for a very long time, without any breakage.

Wet Teng in many ways different from the dry. The main distinguishing characteristics of this detail are the principle of its operation and the fact that it is immersed in water in the inner part of the boiler.In the dry tenes, as already mentioned, the heating element is in a protective vessel, not in contact with the aqueous medium.

Wet tenes are cheaper. As a rule, they are installed in budget class boilers. Dry elements, on the contrary, cost more and are installed in more reliable and expensive units.

Another difference between a wet PETN and a dry one is that in the first version, when replacing, it is necessary to drain the water from the tank. In the case of dry PETN, this is not necessary at all.

Units with dry teng have more compact sizesrather than a device with a wet element. Moreover, in expensive devices, 2 dry PETNs are often installed at once, so they warm up the water much faster.

It may seem that water heaters with dry heaters can last for ages, since the parts do not come into contact with water in the course of their operation. However, in fact, everything is a little different.It is necessary to take into account the fact that electrical interference and stray currents eventually destroy the heating part. For this reason, boilers of this type have not only advantages, but also a number of disadvantages.

For starters, you should consider the advantages of devices with dry PETN:

• All the constituent elements of construction in such units serve much longer than in simple water heaters.
• Devices with dry PETN quickly heat up the liquid.
• To replace the heating element, it is not necessary to drain the water once again.
• Such units are distinguished by the absence of accumulation of scale.
• As a rule, such water heaters have compact dimensions. Thanks to this feature, 2 elements can be placed in one tank at once, and the water heating will accelerate even more.
• These types of water heaters do not need to be cleaned often.
• The quality of water in such units can be almost anything.
• In such devices do not appear air traffic jams.
• In such water heaters, Teng has a high level of protection.
• In use, water heaters with a dry heater are considered to be the most secure - the electric shock in this case is reduced to zero.
• Dry teny is distinguished by quite good interchangeability.Similar designs are suitable for various types of tanks. Wet tena cannot boast of such qualities.

Of course, a lot depends not only on the water heater with a dry heater, but also on the manufacturer who produced it.

Water heaters with dry PETN are not ideal. They also have some drawbacks, which are best seen before purchasing such a unit.

• Such water heaters are more expensive than ordinary boilers.
• Due to the fact that the temperature of the heating element always exceeds the temperature of the water, it is likely that it will overheat and break down.
• Most of the spare parts for such water heaters are quite expensive.
• For such devices there are no universal heating elements. Variants of dry heaters are original, so before purchasing a part you need to make sure that it is suitable for your boiler.
• According to users, such units break down a bit more often than boilers with a wet element.Often you have to turn to expensive replacement parts.
