través del conducto de derivación 106 se bloquea. Las Figures 6a y 6b muestran un regulador de caudal 158 de acuerdo con una variante adicional. También el regulador de caudal 158, de forma análoga al regulador de through bypass conduit 106 is blocked. Figures 6a and 6b show a flow regulator 158 according to an additional variant. Also the flow regulator 158, analogously to the flow regulator

5 caudal 108, se configura a fin de limitar el caudal suministrado a través del conducto de derivación 106 basándose en la presión de agua aguas arriba del regulador de caudal 158. 5 flow 108, is configured to limit the flow supplied through the bypass conduit 106 based on the water pressure upstream of the flow regulator 158.

En otras palabras, el regulador de caudal de 158 regula el caudal suministrado a través del conducto de derivación 106 de manera pasiva. In other words, the flow regulator of 158 regulates the flow rate supplied through the bypass conduit 106 passively.

10 De acuerdo con esta realización, el regulador de caudal 158 comprende un obturador 160 que tiene un canal sustancialmente en forma de T 161 configurado para asegurar el paso de un caudal mínimo incluso cuando la presión aguas arriba del regulador de caudal 158 es menor que el valor umbral mínimo (configuración de la Figura 6a), y el obturador 160 se dispone en In accordance with this embodiment, the flow regulator 158 comprises a shutter 160 having a substantially T-shaped channel 161 configured to ensure the passage of a minimum flow even when the pressure upstream of the flow regulator 158 is less than the minimum threshold value (configuration of Figure 6a), and shutter 160 is arranged in

15 contacto contra la entrada 112. Cuando la presión aguas arriba del regulador de caudal 158 está comprendida entre el valor umbral mínimo y el valor umbral máximo, el obturador 160 está en una posición intermedia en la cámara 109 (configuración no mostrada en las Figuras adjuntas), para permitir el paso a través el conducto 15 contact against inlet 112. When the pressure upstream of the flow regulator 158 is between the minimum threshold value and the maximum threshold value, the shutter 160 is in an intermediate position in the chamber 109 (configuration not shown in the attached Figures ), to allow passage through the duct

20 de derivación 106 de un caudal proporcional a la presión de agua aguas arriba del regulador de caudal 158. Cuando la presión aguas arriba del regulador de caudal 158 supera el valor umbral máximo, el obturador 160 se mueve a tope contra la salida 113, bloqueando así el paso del agua sanitaria a través del conducto de derivación 20 bypass 106 of a flow rate proportional to the water pressure upstream of the flow regulator 158. When the pressure upstream of the flow regulator 158 exceeds the maximum threshold value, the shutter 160 moves fully against the outlet 113, blocking thus the passage of sanitary water through the bypass conduit

25 106. Una variante no representada de la presente invención establece que, en la configuración de operación, el conducto de derivación se dispone por encima del intercambiador de calor favoreciendo la circulación del agua sanitaria cuando el quemador está apagado y no hay demanda por parte de los usuarios. Esto activa un fenómeno de circulación natural gracias al que el agua 106 106. A variant not shown in the present invention establishes that, in the operating configuration, the bypass duct is arranged above the heat exchanger, favoring the circulation of domestic water when the burner is off and there is no demand from the the users. This activates a natural circulation phenomenon thanks to which water

30 en el intercambiador de calor, que es más caliente y menos densa que aquella contenida en el conducto de derivación, tiende a aumentar, dando así paso a la más fría que, a su vez, se calienta al entrar en el intercambiador de calor. Ventajosamente, el calentador de agua 1, 100 de acuerdo con la presente invención tiene una estructura simplificada y menos costosa si se 30 in the heat exchanger, which is hotter and less dense than that contained in the bypass conduit, tends to increase, thus giving way to the colder which, in turn, heats up upon entering the heat exchanger. Advantageously, the water heater 1, 100 according to the present invention has a simplified and less expensive structure if

35 compara con la estructura de los calentadores de agua conocidos y asegura al mismo tiempo que la temperatura del agua no se sobrecaliente cuando el quemador está apagado y no hay demanda por parte de los usuarios. 35 compares with the structure of known water heaters and ensures at the same time that the water temperature does not overheat when the burner is off and there is no demand from users.

El conducto de derivación 6, 106, se configura, de hecho, para suministrar un flujo controlado de agua sanitaria de una forma pasiva. La expresión "forma pasiva" significa sin la ayuda de ningún regulador de caudal controlado activamente por un sistema de control, por ejemplo, basándose en The bypass duct 6, 106 is, in fact, configured to provide a controlled flow of sanitary water in a passive manner. The term "passive form" means without the help of any flow regulator actively controlled by a control system, for example, based on

5 los valores detectados por los sensores dispuestos aguas abajo y/o arriba de la derivación o a lo largo de la derivación y analizado por un dispositivo de control. Los reguladores de caudal activamente controlados son, por ejemplo, bombas y/o válvulas de ajuste, etc. 5 the values detected by the sensors arranged downstream and / or above the branch or along the branch and analyzed by a control device. The actively controlled flow regulators are, for example, pumps and / or adjustment valves, etc.

Básicamente, el conducto de derivación 6, 106 configurado de acuerdo Basically, bypass conduit 6, 106 configured according

10 con la presente invención puede suministrar un caudal controlado de agua sanitaria de forma independiente y sin la ayuda de un ningún sistema de control dedicado. De esta manera, los costes de producción del calentador de agua de acuerdo con la presente invención se reducen significativamente con respecto a los costes de fabricación de los calentadores de agua de la técnica anterior. 10 with the present invention can supply a controlled flow of sanitary water independently and without the help of any dedicated control system. In this way, the production costs of the water heater according to the present invention are significantly reduced with respect to the manufacturing costs of the prior art water heaters.

15 Por último, es evidente que el calentador de agua aquí descrito puede estar sujeto a modificaciones y variaciones sin apartarse del alcance de las reivindicaciones adjuntas. Finally, it is evident that the water heater described herein may be subject to modifications and variations without departing from the scope of the appended claims.
