The main advantages of dry water heaters
Below we list some of the advantages that dry-heated water heaters have.
Complete absence of scale
In water heaters with an immersion heater, scale builds up over time. Its amount directly depends on the hardness of tap water. There are cases when, due to the scale layer formed, the removal of the heating element was a difficult task, since it simply did not pass through the flange hole. In this case, it is not the scale itself that is harmful, but the results of its impact. As a result, there is a violation of heat transfer between the heating element and water, which leads to its breakdown.
Fast water heating
A heater with a conventional heating element will take more time to heat the water to the temperature you need. Yes, and it consumes much more energy. As a result, there are large overpayments for the consumed energy and a long wait for hot water.
The next disadvantage of heating devices with a classic heating element is their inclusion in the network in the absence of water in them. Unlike them, water heaters with a dry heating element are not afraid of such a dry start. The fact is that they are all equipped with special thermal protection units. If this block does not work, only the heater itself will be damaged, and no more.
Ease of maintenance
Devices that have a dry heating element in their design have simpler maintenance. So, if an element malfunctions in such a system, it will not be necessary to drain the water from the tank. You can easily get the heating element through the flange hole and then put it back as well. Preventive examinations of water heaters with a dry heating element are carried out much less frequently compared to submersible counterparts.
No air pockets
A “dry” heating element has smaller dimensions compared to a “wet” heating element. This makes it possible to simultaneously place two heating elements in the tank at the same time, which will directly affect the speed of water heating.

Thus, a water heater with a dry heating element has a large number of advantages. The main factor limiting the purchase of such a device is the price. But over time, this kind of device becomes cheaper, and today you can find models that are only slightly more expensive than heaters with an immersion heater. Moreover, this device is purchased for more than one year, so it would be advisable to purchase a heater with a dry heating element. Such a device is more reliable than analogues and will serve you for many years, delighting you with its work. The choice and purchase of the device is always yours.

The heating element needs a magnesium anode ... any one will last a long time with it ...
Yegorych:
With hard water, any heating element will not last long. Scale forms on the heating element, it begins to overheat and quickly fails. Depending on the intensity of use, its service life is from 0.5 to 1.5 years. As soon as the RCD works (now all electric heaters come with an RCD on the cord), then you need to disassemble the tank, change the heating element with a magnesium electrode. A magnesium electrode is needed to preserve the integrity of the tank from electrochemical corrosion, usually only a metal pin remains from it on the old heating element. Of course, it is better to choose a branded heating element (heating element with the packaging of the tank manufacturer), because they are made with high quality and will last longer. Chinese heating elements sold without packaging are a little shorter, therefore the spiral inside is smaller than it should be, as a result it will heat up more and burn out faster.
