A heating device is designed to heat a liquid while minimizing current that is induced in the liquid. The heating device includes a radiant heat source and a heated member such that the radiant heat source applies radiant energy to the heated member and the heated member is positioned within a vessel. The radiant energy from the radiant heat source is radiated across an empty or gas-filled gap between the radiant heat source and the heated member and the heated member transfers heat to the liquid.

Provides heating pump cover and heating pump, heating pump cover comprises: cover body, comprising flange plate and sealing piece, sealing piece is outside and integrally connected with flange plate, with cross-section stepped, flange plate comprises first surface and second surface arranged oppositely, first surface is for contacting with liquid, temperature control assembly, arranged on second surface, heating body, arranged on one side of first surface, and end of heating body penetrates flange plate, sealing and connecting flange plate, connecting to temperature control assembly by electric circuit. Arranging sealing piece on outer side of flange plate on cover body, with cross-section stepped, after being installed onto pump body, achieving multi-level snapping and sealing, effectively avoiding situation of liquid leakage happen at connecting portion between cover body and pump body due to aging or not tightly sealing, improving sealing performance and reliability of cover body installation.

Disclosed are a heating pump cover and a heating pump. The heating pump cover comprises a cover body, a temperature control device, a raised part, and a heating body. The cover body has a first surface configured to be in contact with liquid on which the heating body is arranged and a second surface opposite to the first surface on which the temperature control device and the raised part are arranged. The raised part forms grooves on the first surface and the temperature control device is arranged on the raised part. The part of the heating body locates in the grooves has a first region which is in contact with the inner wall of the groove and a second region which is arranged interval with the inner wall of the groove.

A portable water heater assembly for heating water being dispensed into a drinking glass includes a base that has a fluid reservoir integrated within the base to contain a fluid and a fill port integrated into the base. A bottle is provided to contain water and the bottle is insertable into the fill port to direct the water into the fluid reservoir. A faucet is integrated into the base to dispense the water from the fluid reservoir. A heating element is integrated into the faucet and the heating element is in thermal communication with the faucet. The heating element heats the faucet when the heating element is turned on thereby heating the water when the water flows through the faucet.

An apparatus and method for heating water using tankless water heater with TRIAC. The present invention is a TRIAC adjustment device that lets a user adjust electric output within a tankless water heater to limit or turn off electricity to a TRAIC within the tankless water heater. As utilized herein, a TRAIC or traic is defined as “a three-electrode semiconductor device that will conduct in either direction when triggered by a positive or negative signal at the gate electrode.”

A water heater can include a housing and a heating system disposed within the housing, where the heating system is configured to heat a fluid. The water heater can also include a switch coupled to the heating system, where the switch operates between a first position during normal operations and a second position during an outage. The water heater can further include a primary power source coupled to the switch, where the primary power source is configured to provide primary power to the heating system through the switch during the normal operations. The water heater can also include an uninterruptible power supply (UPS) coupled to the switch, where the UPS is configured to provide reserve power to the heating system through the switch during the outage, and where the UPS is integrated with the housing.

A water heater includes a first heater, a second heater, and a controller. The controller can enable different operational modes of the water heater, wherein only the first heater operates, only the second heater operates, or both the first and the second heaters operate. The controller can also be configured to enable a hybrid operational mode and a bypass operational mode. Further, in the different operational modes, the controller can direct water flow to at least one of a first conduit coupled to the first heater, a second conduit coupled to the second heater, and a bypass conduit. The controller can be configured to receive input signals relating to environmental conditions around the water heater and/or an aquatic system in which the water heater is installed.

The application relates to an induction heating device having a housing and a fluid duct. The fluid duct is arranged in the housing and has a fluid inlet and a fluid outlet. Inside the housing is an induction element which generates an alternating magnetic field and which is separated from the fluid duct in a sealed manner by at least one wall. The device also includes at least one metallic areal heating element arranged in the fluid duct which can be heated by the alternating magnetic field.

A water heater and a method of heating water utilizing microwave energy are disclosed. The water heater includes an inlet pipe connecting tubular coils. The tubular coils overlap over one another in a pyramid-shape structure. The tubular coils include a microwave generator positioned adjacent to them. The water heater includes an insulation member that positions around the tubular coils. The tubular coils connect to an outlet pipe including a pressure relief valve and a switch. The inlet pipe supplies cold water to the tubular coils. The microwave generator produces microwave energy directed at the tubular coils. The microwave energy penetrates into the tubular coils and heats up the water. The insulation member reflects back the microwave energy into the tubular coils and ensures there is no loss of energy. The hot water flows through the outlet pipe.

Provided is an instant water boiling device, which comprises: an instant water boiler provided with a water inlet and a water outlet communicated with a faucet; a control panel arranged on the faucet; and a controller in signal connection with the control panel and the instant water boiler. According to the invention, the control panel is separated from the instant water boiler, which is convenient to install, the instant water boiler with a larger volume can be installed in a cabinet under a tabletop, which saves a space of the tabletop, and meanwhile, the control panel is installed on the faucet, which is convenient for a user to operate the control panel, thus facilitating the operation, simplifying the installation, and saving the space of the tabletop.
