Abstract:
A residential water heater comprising an insulated tank, for containing water to be heated; at least one partition of said tank, for dividing said tank into at least two sub-tanks, said division substantially not allowing water transition therebetween; an individual heating apparatus for each of said at least two sub-tanks; and a selecting mechanism for selecting one of said at least two sub-tanks as the current sub-tank for dispensing the heated water therefrom, thereby obtaining higher temperature of primary water to be dispensed from said tank at less power than heating an un-partitioned tank.
Abstract:
Die Erfindung betrifft ein elektrisch betreibbares flüssigkeitsdurchströmtes Heizgerät (100) mit einem Gehäuse (1). Das Heizgerät (100) umfasst eine elektrisch betreibbare Heizvorrichtung und eine Flüssigkeitskammer zur Aufnahme einer wärmeübertragenden Flüssigkeit. Die Flüssigkeitskammer weist eine Vielzahl von Scheibenpaaren (11g) aus miteinander in gegenseitigen vorgegebenen Abständen verbundenen Scheiben (11) auf, wodurch Flüssigkeitsströmungskanäle zwischen den Scheibenpaaren (11g) erzeugbar sind. Die elektrisch betreibbare Heizvorrichtung ist als ein Die elektrisch betreibbare Heizvorrichtung als ein Heizverbund (20) mit einer Vielzahl von Heizelementen (22) ausgebildet ist, wobei der Heizverbund (20) zwischen den Flüssigkeitskammern anordenbar ist durch Einführung der Heizeinheiten (21) in die zwischen den Scheibenpaaren (11g) erzeugten Aufnahmeräumen.

Abstract:
The invention relates to a cast iron or aluminum sectional boiler, in particular a condensing boiler, comprising substantially circular sections, wherein a forward section (1), a rear section (2) and at least one central section (3) are provided that form a combustion chamber (4) comprising substantially peripheral hot gas passages, the annular water chambers (5) of said sections being connected together by way of hubs (6, 6'), a return connection and a flow connection, an exhaust gas nozzle (12) and at least two anchor rods for holding the block of sections together. The object of the invention is to optimize a cast iron or aluminum sectional boiler with regard to compactness and robustness in particular. The invention is characterized in that annular gaps (9, 10) are provided between two respective adjacent sections (1, 2, 3, 7) as hot gas passages, and that the hot gas passages are subdivided into a primary section (P) and a secondary section (S), wherein each of the hot gas passages runs approximately radially in the primary section starting from the combustion chamber (4) outward and ending at an exhaust gas collection chamber (11) on the outside of the respective sections (1, 2, 3, 7), wherein the hot gases overflow there to the secondary section (S) and wherein at least one hot gas passage runs approximately radially in the secondary section (S) starting from the exhaust gas collection chamber (11) and going inward to an exhaust gas nozzle (12).
Abstract:
There is provided an instantaneous heating apparatus configured to heat introduced water, while water is flowing therein, to a certain temperature by means of a heating unit during which the generation of steam is minimized. The instantaneous heating apparatus includes: a main body having an inlet through which water is introduced and an outlet through which water is expelled; and a heating unit provided in the main body and configured to heat water introduced into the main body, wherein at least one of the main body and the heating unit is configured such that water introduced into the main body through the inlet is heated to a predetermined required temperature while flowing for a certain period of time and the generation of steam is minimized.
Abstract:
When feedback loop control is used for controlling a temperature of liquid at an outlet (5) of a flow through heater, a volume of an ineffective portion (4) of the flow through heater at the outlet (5) constitutes a dead volume which causes a delay in the feedback process. In order to minimize the delay, an insert (6) is applied, which serves for reducing the dead volume by occupying most of this volume. In a practical case, the insert (6) comprises a duct system (12) for conveying liquid from a liquid conveying conduit (2) of the flow through heater to an outlet (10) of the insert (6). Preferably, a volume of such a liquid conveying duct system (12) is relatively small, so that the presence of the duct system (12) in the insert (6) does not spoil the dead volume reducing effect of the application of the insert (6).
