In a heat storage water heater, a water container 5 is surrounded by a thermal storage block 4, is connected via a line 10 to a header tank 3, and has a water discharge line 9 controlled by a valve 7. When there is low demand for hot water, steam pressure in the container 5 forces water into the header tank to reduce the heat input to the water. As illustrated, the heater is incorporated in a central heating system having a radiator 6 and a water circulating pump 8. The system includes either a line 1 and nozzle 2 or a line 11 and riser tube 12 for returning water to the container 5. The nozzle 2 is such that return water falls on to the surface of the water in the container 5 without touching the walls of the container. A number of water heaters may be connected in parallel to form a single unit, Fig. 2 (not shown). The ...

Control Algorithm for Water Heater

Номер: US20130092102A1
Автор: Raheel A. Chaudhry
Принадлежит: Rheem Manufacturing Co

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.

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. The normalized leakage signal is used, if a particular absolute value of the leakage signal is exceeded or if a particular slope of the profile of the leakage signal is exceeded, in order to top up the fluid chamber with more fluid and/or to reduce the heating power of at least one heating element. 1.
