WATER-HEATER Russian patent published in 2008 - IPC F24H1/20 

FIELD: heating.

SUBSTANCE: invention relates to energetics and can be used in direct-flow water heaters. In the water-heaters with a heating module, which in its heating section, at least, in the main annular internal space is connected to a supply and drainage, contains, at least one tubular heating element, the heating section has an interruption on the course or the ring, which defines two separate beginnings of the route of flow. At the break there is an inlet zone at the beginning of the course of the flow. The outlet device of the heating section connected with the discharge, removed from the inlet zone and located such that both routes of flow have approximately identical length from the inlet to the outlet device. During the working of such a water heater there is no uncontrollable mixing of cold and hot water, and parts of the heater with increased energy release are well cooled, which increases the operational reliability and increases durability of the heating element.

EFFECT: increase in the operational reliability of a heating element and increase in durability.
