A water heating assembly, related kit, use and method make use of a temperature control near a point of use of water, so as to reduce a time response for hot water at this point of use are provided. The water heating assembly includes a tank for containing water, an inlet temperature sensor for sensing an inlet temperature of the water upstream of the tank, and a valve located upstream of the tank. The valve is actuated when the sensed inlet temperature reaches a given temperature set-point such that the water is bypassed from the tank and directly sent to the point of use. The water heating assembly is configured such that the point of use can be fed with water at the desired temperature in a reduced time, the water coming directly from the hot water source and/or the water heating assembly, thereby saving water, energy and time.

A hot water supply device (10) is provided with: a first device (for example, a kitchen remote controller (13)) for performing control relating to hot water supply; a second device (for example, a water heater (11)) that is communicably connected to the first device and performs control relating to hot water supply; and a communication unit that is provided in the first device and can be connected to an external communication network. The first device divides data of control software of the second device acquired from an external device (for example, a server (50)) via the communication unit, into a plurality of parts, and transmits to the second device.

A water heater system includes a gas burner configured to selectively produce flue gases, and a heat exchanger for heating water in the water heater system. The water heater system is operable in a heating mode, and a standby mode. An exhaust assembly is in communication with the heat exchanger, and includes a condensate collector configured to receive the flue gases and condensate. A first temperature sensor is positioned to sense a temperature of the condensate within the condensate collector. The first temperature sensor is configured to detect a rate of temperature change of the condensate. A controller is configured to determine a leakage when the rate of temperature change adjusts from a first state to a second state when the water heater system is in the standby mode after the water heater system was in the heating mode.

A LWCO remote monitoring and diagnosing system or device features a signal processor configured to: receive signaling containing information for running a remote low water cut off (LWCO) mobile application, and also containing information about historical data related to a LWCO circuit that monitors and controls a burner of a boiler that opens and closes to provide water to the boiler depending on the water level in the boiler; and determine corresponding signaling containing information about the historical data requested based upon the signaling received.

A switch assembly includes an automatic type 11 switch having 1 and 2 contacts and 3 and 4 contacts with the 2 and 3 contacts being shorted together, configured to respond to a water level of a boiler, short the 1 and 2 contacts when the water level is high, short the 3 and 4 contacts when the water level is low; and an electronic circuit board having a processor configured to sense signaling containing information about the 1, 2/3 and 4 contacts, and provide control signaling containing information about the water level of the boiler. The electronic circuit board also includes a relay configured to respond to the control signaling, and turn the relay on/off.

In one aspect, a first device includes a processor and storage accessible to the processor. The storage bears instructions executable by the processor to receive input from a water heater meter that monitors a water heater and provide an output comprising information pertaining to a time estimate related to the provisioning of heated water based on the input.

An on-demand hot water dispenser includes a housing, a water heating system received in the housing, and a faucet connected to the water heating system through the housing for dispensing hot water into a container. A drip tray is positioned below the faucet and a screen covers the drip tray to support the container during dispensing of the hot water.

The present invention relates to an instantaneous heater, comprising a heating assembly, wherein the heating assembly includes a heating element, a first shell, a first inlet tube, a first water outlet, a hot water cavity, a cold water cavity and a capillary tube, the hot water cavity is in the first shell, the heating element is in the hot water cavity, the hot water cavity communicates with the cold water cavity, the first inlet tube communicates with the cold water cavity, the first water outlet is on the top of the first shell and communicates with the hot water cavity, the capillary tube is in the cold water cavity, one end of the capillary tube communicates with the hot water cavity and the other end communicates with the outside of the first shell. The instantaneous heater boasts simple structure, low cost and effective prevention of vapor from rapidly erupting.

A heater for heating liquid to boiling comprises a heating element (48; 106), a first heating region (18, 20; 100) heated by said heating element (48; 106) for heating liquid flowing therethrough to a temperature below boiling, and a second heating region (22; 102) for heating said liquid to boiling. The second region permits the exit of steam therefrom separately from heated water.

A hot water supply device (10) is provided with: a first device (for example, a kitchen remote controller (13)) for performing control relating to hot water supply; a second device (for example, a water heater (11)) that is communicably connected to the first device and performs control relating to hot water supply; and a communication unit that is provided in the first device and can be connected to an external communication network. The first device divides data of control software of the second device acquired from an external device (for example, a server (50)) via the communication unit, into a plurality of parts, and transmits to the second device.
