Abstract:
This invention concerns a device for conveying heated water in a water heater from a first position located at or proximate a heating element of the water heater to a second position. The device includes a water impervious conduit which has a first end for connection to the heating element and a second end which is, in use, a free end located at the second position. At least a portion of the conduit is buoyant so that, in use, the second position is above the first position such that the device conveys heated water from the first position to the second position by means of thermosiphoning. The invention also concerns a water heater including such device and a method of manufacturing such device.
Abstract:
A heater comprises an inlet (1) for a medium to be heated, an outlet (2) for the medium, and at least two cassettes (5). Each cassette comprising a first plate (6) comprising a first main surface(8) and a second plate(7) comprising a second main surface(9). The first and second plates are attached to each other and enclose a respective flow channel for the medium. The cassettes are arranged beside each other with a space (23) between the cassettes for an electric heating element (31). The electric heating element abuts the first main surface of one of the cassettes and the second main surface of the adjacent cassette. The heater comprises two distance members (19) extending between said one cassette and said adjacent cassette. The distance members define said space.
Abstract:
A modular manifold for a tankless water heater includes a first cavity member and a second cavity member. The first cavity member includes a first opening, a second opening, and a first base wall. The second cavity member is coupled to the first cavity member and includes a first opening, a second opening, and a second base wall. Two of the openings are configured to receive a first conduit and a second conduit. The first and second base walls and the two openings that receive the first and second conduits define a fluid flow path through the modular manifold.

A fire tube boiler includes a perforated flame holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Abstract:
A boiler comprising: a flexible tank configured to be collapsed when empty and to expand up to a predefined shape upon being filled with a liquid; a liquid inlet to said flexible tank; a liquid outlet from said flexible tank; a heating element port in said flexible tank.
Abstract:
Die Erfindung betrifft eine Heizvorrichtung (10) für ein Fahrzeug, mit: einem Strömungsweg (14, 16, 20, 22, 24) für ein flüssiges Wärmetransportmittel; einer elektrischen Heizeinrichtung (34) zum Erzeugen von Wärme und zur Abgabe von erzeugter Wärme an das Wärmetransportmittel auf einem Heizabschnitt (20) des Strömungsweges; und einer elektronischen Steuereinrichtung (26) zum Steuern einer Heizleistung der Heizeinrichtung. Die Steuereinrichtung (26) ist mit einem Wärmeabgabekörper versehen, zur Abgabe von Abwärme der Steuereinrichtung (26) an das Wärmetransportmittel auf einem Vorheizabschnitt (16) des Strömungsweges stromaufwärts des Heizabschnittes (20). Ein Verfahren zur Kühlung der Steuereinrichtung ist ebenfalls beschrieben.
Abstract:
A dual purpose heat exchanger comprises a central heating fluid circuit and hot utility water circuit. The exchanger contains fired or heated by flow of water or steam main heat exchanger and coil (2) enclosed by an external jacket (3) equipped with an inlet stub pipe (6) for fluid heating the utility water in the coil (2) as well as an inlet stub pipe (4) and outlet stub pipe (5) for utility water; however, the flow chamber of fluid heating the utility water in the coil (2) is connected with the flow chamber (8) of heated fluid in the main exchanger. Preferably, the coil (2) is wound on the jacket (1) of the main exchanger, and the flow chamber of fluid heating the utility water in the coil (2) is connected through at least one overflow hole (7) with the flow chamber (8) of heated fluid in the main exchanger.
