This invention relates to an electrical heating device 10 and to an installation including such a device 10. The heating device 10 is for use in a heating apparatus, for e.g. a geyser and includes: a mounting formation 12 for removably mounting the device 10 to the geyser; a first heating element 14.1 which is connected to the mounting formation 12 and which includes a first pair of electrical connection terminals 20.1 which are connectable to a first power supply; and a second heating element 14.2 which includes a second pair of electrical connection terminals 20.2 which are connectable to a second power supply, independent of the first power supply. The first and second heating elements 14 are electrically insulated from each other in a configuration in which the first and second power supplies are simultaneously connectable to the respective heating elements 14.

A device adapted to accumulate the thermally treated fluid is described, comprising: a containment chamber of said thermally treated fluid (1), at least one separator (4) arranged with a substantially vertical development in the containment chamber, said at least one separator being adapted to divide said chamber in at least two parts, and to leave openings at the opposite upper (6) and lower (7) end of said chamber, by means of which the fluid can pass in order to determine a rotatory circulation of the fluid in the cross direction in said chamber.
Abstract:
A solar photovoltaic water heating system is disclosed having a photovoltaic solar panel array, a storage tank containing water to be heated, a resistance heating element in the water to be heated. The water heating system matches the load resistance of the resistance heating element to the power that is available from the photovoltaic solar panel array in order to maximum energy transferred to the water in the storage tank.

Abstract:
Disclosed is a water heating system comprising: a hot water storage tank having a first port located in a lower region of the tank and a second port located in an upper region of the tank; a water flow pathway extending from the first port through a heating chamber to the second port; electrical heating means (for example a heating element) arranged to heat water within the heating chamber, when required, so that water within the water heating system will circulate from the first port to the second port through the heating chamber, by convection, when water is not drawn from the water heating system; a water supply outlet communicating with the water flow pathway intermediate the heating chamber and the second port; and a check valve arranged to restrict the flow of water out of the hot water storage tank by way of the second port when water is drawn from the water heating system through the water supply outlet. Therefore, when water is drawn from the system, the flow of water from the tank to the water supply outlet is restricted, and a much higher proportion of water passing through the water supply outlet has flowed directly from the heating chamber. Since water received at the water supply outlet directly from the heating chamber will have been more recently in contact with the electrical heating means than water received from the hot water storage tank via the second port, less electrical heating energy is required in order that water at a given temperature may be drawn from the system, or water drawn from the system will be at a higher temperature, than water drawn from a system lacking a check valve. Therefore, the system of the present invention is more efficient than a system lacking a check valve.
