Electrode boilers

Electrode boiler

— a variety of electric boilers (see the relevant paragraph), also known as ion boilers. The key difference between such devices is that they do not have heating elements: heating occurs because the electric current passes directly through the liquid coolant. In addition to the general advantages of all electric boilers (small size, ease of installation and control, the ability to use advanced automation, etc.), such models also have such advantages as very high efficiency and good heating rate. It should be noted that even if the coolant leaks, there is practically no danger of electric shock. On the other hand, electrode boilers are very demanding on the quality of the coolant: it must be water with a strictly defined salt concentration, and during operation electrolysis gases must be regularly removed from the heating system and the coolant must be added to it. In addition, units of this type are not compatible with RCD protection.
