According to this principle, no continuous control of the temperature is given, the heating departments are retrieved separately from each other and it can be generated within the liquid quantities of constant temperature and flow rates. Mixtures between the specified limits do not take place. It is also no preheating, without immediate maintenance of the heating elements, possible. However, the main drawback here is that the sensor-controlled heating elements come into direct contact with the water to be heated.

The sensors used behave redundantly to one another and ensure that the tank-free hot water heater remains functional even if one of the sensors fails. If the need for hot liquid expires or falls, the outlet temperature sensor is activated a rise in temperature, whereupon the proportional controller throttles the supply of energy to / to the heating element / heating elements. As soon as the pre-set temperature is reached in the coil coil tank and all sensors, the energy supply to the heating element (s) is interrupted.

Abstract

L'invention concerne un chauffe-eau sans réservoir, destiné aussi bien à alimenter une maison en eau chaude domestique par l'utilisation de dispositifs de chauffage électriques qu'à injecter de l'eau chaude dans des circuits de chauffage afin de chauffer des pièces. En configuration modifiée, ce chauffe-eau sans réservoir peut être également utilisé pour chauffer d'autres liquides que l'eau, ce qui nécessiterait de choisir un autre matériau en particulier pour les tubes hélicoïdaux placés à l'intérieur dudit chauffe-eau, en conférant également à ces tubes hélicoïdaux un autre diamètre et une autre configuration hélicoïdale en fonction de ce diamètre. Le grand avantage de cette invention est que le liquide à chauffer n'entre pas en contact direct avec les éléments chauffants électriques pour entraîner rapidement l'accumulation de tartre dans le cas de l'eau. En effet, des éléments chauffants sont placés dans un espace limité, en barres, au milieu de tubes hélicoïdaux traversés par de l'eau ou par d'autres liquides, et leur énergie de chauffage est transmise indirectement aux tubes hélicoïdaux par l'intermédiaire d'un fluide inerte se trouvant dans l'espace limité susmentionné et par convection. Une température présélectionnée du liquide à chauffer est détectée au moyen de capteurs à la sortie et à l'entrée du dispositif et commandée à l'intérieur de ce dernier, de sorte que la température présélectionnée reste constante à chaque fois qu'une quantité de liquide est soutirée.
