A heater system includes a heater bundle and a power supply device. The heater bundle includes a plurality of heater assemblies and a plurality of power conductors. The heater assembly includes a plurality of heater units, each heater unit defining at least one independently controlled heating zone. The power conductors are electrically connected to each of the independently controlled heating zones in each of the heater units. The power supply device is configured to modulate power to each of the independently controlled heater zones of the heater units through the power conductors.

A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.

A water dispensing apparatus includes a hot water module configured to heat supplied water using an induction heating method, a water supply pipe configured to supply water to the hot water module, a flow rate control valve provided on the water supply pipe to control a flow rate of water supplied to the hot water module, a flow rate sensing device provided on the water supply pipe to sense the flow rate of water supplied to the hot water module, and a controller configured to increase an opening speed of the flow rate control valve when the flow rate of supplied water sensed through the flow rate sensing device is equal to or less than a set flow rate.

The present disclosure relates to an integrated modulating forced air electric heater with temperature control protection used to limit the electric heater output to protect the forced air electric heater components from overheating. The integrated modulating forced air electric heater with temperature control protection may be used to prevent the electronic heating element from overheating. The integrated modulating forced air electric heater with temperature control protection may also include protection to prevent a switch from overheating where the switch is used to switch power to the electric heating element.

A control system of a water heater apparatus with a combustible gas burner is presented where the apparatus includes a pilot burner with an intermittent-type pilot flame, a main burner, a pilot valve and a main valve, a control unit, a flame detection electrode, introduced into the flame of the pilot burner, and which is configured to conduct an ionization current. The control unit is configured to measure/detect a variation involving increase/decrease of the intensity of ionization current detected, the variation in intensity of ionization current being generated during the change between a first condition, in which the ionization current identifies the ignition state of only the pilot burner, and a second condition, in which the ionization current identifies the simultaneous ignition state of the pilot burner and the main burner so that, by detection of the measurement/variation of ionization current, the effective ignition of the main burner is recognized.

A heating and hot-water supply apparatus shortens the time taken for hot-water supply to stabilize at a set temperature in response to a request for a hot-water supply operation during a heating operation. The apparatus performs, using a common heating medium heated by a heater, a heating operation by circulating the heating medium through a heating terminal, and a hot-water supply operation of heating service water through heat exchange with the heating medium circulated through a hot-water supply heat exchanger and supplying hot water. A distribution unit (three-way valve) changes a distribution ratio of the heating medium between the heating terminal and the hot-water supply heat exchanger. A controller controls an amount of heat generated by the heater for the heating operation or the hot-water supply operation, and stops heating with the heater when the temperature of the heating medium reaches a predetermined upper-limit temperature.

The apparatus for supplying hot water comprises: at least one processor; a heat exchanger connected to the at least one processor, and configured to receive tap water through a tap water inflow pipe, heat the supplied tap water by means of heat exchange to thereby generate hot water, and discharge the generated hot water through a hot water supply pipe; a burner configured to directly or indirectly provide heat required to generate the hot water; a mixing valve connected to the at least one processor and installed on a mixing pipe connecting the tap water inflow pipe and the hot water supply pipe, and configured to mix the tap water with the hot water discharged from the heat exchanger and flowing through the hot water supply pipe; and a memory connected to the at least one processor and configured to store instructions.

A heating and hot-water supply apparatus performs a heating operation by heating a heating medium with a heater and circulating the heating medium through a heating terminal, a hot-water supply operation by circulating the common heating medium through a hot-water supply heat exchanger, heating service water through heat exchange with the heating medium, and supplying hot water, and a simultaneous operation of the heating operation and the hot-water supply operation, and controls a distribution ratio of the heating medium between the heating terminal and the hot-water supply heat exchanger. The apparatus determines whether the heating terminal proceeding in the heating operation is a suspendible terminal to suspend the heating operation or an unsuspendible terminal not to suspend the heating operation in response to a request for the hot-water supply operation.
