Water heaters with 2 heaters

2 heaters

— devices equipped with two heaters. The meaning of this function depends on the features of a particular model. So, in combined water heaters (see "Energy source"), two different types of heating elements are provided, in tankless models a similar design is used to increase productivity, and in storage models to improve the speed and uniformity of heating. In addition, in non-combined units, power control can be performed by turning individual heaters on and off.
