Abstract (en)
This relates to an additional heater (2; 3; 4; 5) associated with an accumulator water heater (1) which, according to the variants, is able to pre-heat the water introduced into said accumulator water heater (1) or post-heat the water delivered to the user. <??>In the first case, the negative effects of the so-called "mixing" operation are reduced or eliminated; in the second case the heat dispersion in accumulator water heater (1) is reduced because the water can be maintained at a temperature lower than that required by the user. <??>The additional heater (2; 3; 4; 5) is suitable for construction in the form of an accessory kit for retrofitting assembly on accumulator water heater (1) normally already in operation. <IMAGE>
