CA 2464753

A water heater or boiler, comprising a conduit (2) having an inlet (10) and an outlet (20), means for causing water to flow through said conduit (2) from said inlet (10) to said outlet (20), and one or more radio frequency wave heating sources (3) arranged such that water is heated thereby as it flows through said conduit (2) from said inlet (10) to said outlet (20). The radio frequence wave heating source (3) is preferably a microwave heating source, and the apparatus may include one or more waveguides (7) for directing the microwaves towards the conduit (2). The invention provides a water heater or boiler which can heat water on demand (but required the need for a storage tank or the like) using microwave or other radio frequency heating source. One or more microwave radiation absorption members (not shown), such as a metal rod or piece of wire wool, may be disposed in the water to be heated to significantly increase the efficiency of the heater.

L'invention concerne un chauffe-eau ou un bouilleur, comprenant un conduit (2) doté d'une admission (10) et d'une évacuation (20), un système d'écoulement de l'eau à travers le conduit (2) depuis l'admission (10) vers l'évacuation (20), et une ou plusieurs sources chauffantes en radiofréquence (3), visant à chauffer l'eau durant son écoulement à travers le conduit (2) depuis l'admission (10) vers l'évacuation (20). On choisit de préférence comme source chauffante en radiofréquence (3) une source chauffante hyperfréquence, et l'appareil peut comprendre un ou plusieurs guides d'ondes (7) orientant les ondes hyperfréquence vers le conduit (2). L'invention concerne un chauffe-eau ou un bouilleur permettant de chauffer l'eau à la demande (mais nécessitant un réservoir de stockage ou autre), qui utilise une source chauffante hyperfréquence ou autre source chauffante en radiofréquence. On peut disposer dans l'eau un ou plusieurs éléments absorbant le rayonnement hyperfréquence (non représentés sur les figures), du type tige métallique ou élément en laine à base de fils, ce qui permet de chauffer le ou les éléments en question afin d'améliorer sensiblement l'efficacité du chauffe-eau.
