The characteristics of the water in your region.

5. ACCORDING TO THE CHARACTERISTICS OF THE WATER
The quality on the water in the distributor system can directly yes influence on life on yours device . If a lot firm can yes reasons cauldron stone , esp on the heating element . If she is aggressive , she can yes provoked in a hurry corrosion on the water reservoir . 
Water heater and, manufactured in ELDOMINVEST, work long ago in dozens countries with different characteristics on the water . The long-standing us practice showed that​ there isn't universal decision , but us allow yes develop successful product concepts for everyone type water .

5.1. Water heater and with dry heaters .
Ours decision for the areas with hard water is the ELDOM Eureka family - water heaters with the so- called " dry " tubular or ceramic our heater elements . Dry tubular heaters everything they call the heating ones elements on the water heater , which no are in direct contact with water , and are placed in special designed tubular muffs , over which give off heat . Through them everything provides direct heat exchange , without yes there is significant thermal lost . The energy one them characteristic and efficiency on heating are similar to these on the standard ones submerged tubular heaters , but so like no enter directly​ contact with aggressive waters , theirs life is significant longer .
Here it is some from the main ones advantages on water heaters ELDOM Eureka at solving on similar problems :
- The heating element has no direct contact with the water - it is heated through the steel enamelled tube in which it is placed. Due to the optimally selected power of the heaters up to 1.2 kW, a much smaller amount of lime (scale) is deposited on the enamel coating of the ELDOM water heaters. It does not accumulate, but falls as sediment to the bottom of the water container. The absence of limestone on the pipe preserves the efficiency of water heating throughout the entire operational period.
- Effective protection from corrosion - enameled tube in which the heating element is placed tightly , it becomes part from overall the enameled one internal surface on the water content , which effectively everything protects from both anode with enlarged mass , which we install in the water heaters ELDOM. 
- Double electric key - ELDOM Eureka water heaters with dry tubular heaters they have double electric key for gradually inclusion on both heating the element which optimize the regime on warming up on the water. 
- Extremely facilitated repair - at replacement on the heating element no everything imposes draining on the water heater .
