Disclosed is a system and method for monitoring hot water supply in a load control network, and more particularly for ensuring that there is sufficient hot water available for a customer participating in a demand response program that uses, at least in part, water heaters as a component of the demand response program. A multi-meter that is external to the water heater is used to monitor an electrical power supply circuit on the water heater, to report preferably volts, amps, and power factor of the water heater. The multi-meter may use these measured values to, in turn, determine a current charge state of the water heater and thus ensure maintenance of an adequate supply of hot water, even in times of demand response curtailment.

The present disclosure provides a water heater including a bypass conduit to allow flow of cold water from an inlet pipe to an outlet pipe, and an outlet temperature sensor coupled to the outlet pipe downstream of an outlet of the bypass conduit, to sense temperature of mixture of hot water and cold water in the outlet pipe. An electronic mixing valve is disposed along the inlet pipe to receive temperature data of water mixture from the outlet temperature sensor and compare temperature of the water mixture with a predefined temperature value. In response to determining that the water mixture is flowing through the outlet pipe, the electronic mixing valve regulates the flow of cold water through at least one of the bypass conduit and the inlet pipe until the temperature of the water mixture is within a predetermined range of the predefined temperature value.

A heating system including a heating device; a thermal battery loop including a thermal battery and a pump configured to circulate a working fluid through the thermal battery; a fluid conductor for receiving the first fluid at an inlet at a first temperature and delivering the first fluid at a second temperature; a first heat exchanger configured to thermally couple the heating device and the fluid conductor at a first location of the fluid conductor; a second heat exchanger configured to thermally couple the thermal battery loop and the heating device; and a third heat exchanger configured to thermally couple the thermal battery and the fluid conductor at a second location of the fluid conductor, wherein the second location of the fluid conductor is a location downstream from the first location of the fluid conductor between the inlet and the outlet of the fluid conductor.

Control of temperature of water delivered by a dual-stage water heater having an external boiler with a first heater as first stage and an internal duct (water booster) with a second heater as second stage. A control loop based on a measured water temperature in the boiler and controls the first heater. A second loop calculate a reference booster water temperature based on the temperature error at the outlet (difference between a measured outlet water temperature and a reference outlet water temperature) and controls second heater based on error between reference booster water temperature and measured booster water temperature. The reference outlet water temperature depends on type of beverage (e.g. espresso, cappuccino) and includes a temperature profile with different temperature for different sub-beverages (e.g. coffee, milk). Takes into account physical response times, inertia of heater and anticipate sudden changes of reference water temperature at hot water outlet.

A water heater system includes a water heater having a first water outlet and a second water outlet. The water heater system further includes a flow detection device coupled to the first water outlet to detect a water flow through the first water outlet. The water heater system also includes a flow control valve fluidly coupled to the second water outlet. The flow control valve is configured to control a flow of water through the second water outlet based on whether the water flow through the first water outlet is detected by the flow detection device.

The invention is a double-circuit electric boiler for boiling a warming heat-carrying agent and a residential hot water. A hot water supply circuit first container and a second container with an electric heater for the heat-carrying agent of a warming circuit are arranged in a housing. Outer surfaces of inner walls of the warming circuit second container are in a contact with the water of the hot water supply circuit inside the first container. The electric heater for the heat-carrying agent is isolated by the second container walls from a contact with the water of the hot water supply circuit inside the first container. Both containers have separate inlet and outlet ducts and separate isolated temperature sensors. In a second embodiment of the boiler, an electric heater having heating areas isolated by the inner walls of the second container is further mounted in the first container.

The present invention provides an electric boiler having a heating element surrounded by a thermally conductive inner container to define an inner passage about the heating element, the inner container having an inlet 13, 14 and an outlet for a flow of water and is arranged such as to cause water received at the inner container inlet to flow along the inner passage in close proximity to a surface of the heating element, the boiler further comprising an outer container in which the inner container is substantially located, the outer container defining an outer passage about at least part of the inner container, the outer container having an outlet into the inner container wherein the outer container is arranged such as to cause water to flow along the outer passage in close proximity to a surface of the inner container, such that water received in the boiler makes at least a double pass through the boiler to increase the potential heat transfer to the water.
