A storage type water heater, which may have either fuel or electric-based heating apparatus, is provided with a control system incorporating a control algorithm that monitors the time between heat demands and then sets the tank water setpoint temperature accordingly to lower the effects of water stratification due to periodic heat demands, and also save energy. When the time between consecutive heat demands is less than a predetermined setback time, for a number of heat demands equal to a predetermined setback limit, a setback mode is activated and responsively operates to reduce the setpoint temperature by a predetermined setback offset at the next cycle. The original control setpoint temperature is restored once the time between two successive heat demands is more than the setback time.

Номер: US20140096726A1
Принадлежит: Rheem Manufacturing Co

A tube disposed in the combustion chamber of a standing pilot type fuel-fired water heater is used to increase the overall efficiency of the water heater by improving the heat transfer from the pilot flame to the tank during standby periods by funneling the standing pilot flame upwardly through the tube in a manner concentrating the pilot flame heat against an underside portion of the bottom head of the water heater tank. To further increase water heater efficiency, the pilot burner is of a dual input type. Various pilot burner operational algorithm modes are disclosed for causing the pilot burner to operate at a high firing rate during main burner operation, and at a low firing rate during standby periods.

In a method for operating a heating device, fluid is initially introduced into a fluid chamber, then the heating elements of the heating device are switched on and a leakage current is detected as a temperature-dependent current flow through a dielectric insulation layer. A supply voltage of the heating devices is measured and is taken into account in an evaluation of the temperature at the fluid chamber as a function of the leakage current. The leakage current is converted into a leakage voltage by means of a resistor, which is then divided by the measured supply voltage. Subsequently, the quotient obtained may be multiplied by a compensation value in order to obtain a normalized leakage signal, which is normalized to a base value of the supply voltage.

Принадлежит:

Mobile water heating systems for producing hot water are disclosed herein. In one embodiment, a mobile water heating system includes a water heater having an oval-cylindrical shape. The water heater includes a shell, a lid and a water reservoir having a screen. A first heating coil and a second heating coil can extend between the screen and a first cone and a second cone, respectively. A first burner and a second burner can be configured to mix and combust fuel and air and direct the resulting flames through the heating coils. Pall rings can at least partially fill an interior volume of the water heater and the combustion of the fuel and air can heat the heating coils and the pall rings. Water can be heated by being directed through the heating coils and through a water manifold positioned to spray water on the pall rings. 120-. (canceled)21. A water heating system comprising:a shell defining an internal volume;a heating coil positioned at least partially within the internal volume and including a tube coiled in the shape of a cylinder having an upper end portion and a lower end portion, wherein the tube is positioned to receive water at an inlet positioned in the upper end portion and direct the water to an outlet positioned in the lower end portion;a manifold having a plurality of nozzles, wherein the plurality of nozzles are positioned to spray water within the internal volume;a water reservoir positioned to receive water from the heating coil and the manifold; anda burner positioned to direct flames into the cylinder of the heating coil.22. The water heating system of claim 21 , further comprising a vaporization coil having a fuel inlet for receiving fuel and a fuel outlet for providing fuel to the burner claim 21 , wherein the vaporization coil is positioned to receive heat via the flames from the burner and transform at least a portion of the fuel in the vaporization coil from a liquid fuel to a gaseous fuel.23. The water heating system of claim 21 , further ...
