Water heaters with 3 heaters

3 heaters

— devices equipped with three heaters at once. Most of these models are combined (see "Energy source") and are created according to the "2 + 1" scheme — two heaters of the same type plus a third of a different type (for example, two electric heating elements and a heat exchanger). However, in addition to this, there are also electric models with this feature — they have three heating elements for the most uniform heating of the tank and/or for power control by turning individual heaters on and off.
