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.

Provided is an aerosol generating device which is capable of stopping aerosol generation at an appropriate timing. This aerosol generating device includes a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a circuitry which controls the power supplied from the power source on the basis of the measurement value. The circuitry controls to increase a power supply amount per unit time in response to a first condition that the measured value is equal to or larger than a first threshold being satisfied, and to decrease the power supply amount per unit time in response to a second condition that the measured value is less than a second threshold greater than the first threshold and a third condition which is different from the first condition and the second condition being satisfied.

Systems and processes for use in heating articles include passing a carrier loaded with an article through a vessel inlet and into a first vessel portion and moving the loaded carrier in a first direction through the first vessel portion away from the inlet. During at least a portion of the movement through the first vessel portion, the article is contacted with a first fluid medium. The loaded carrier is moved carrier in a second direction opposite the first direction through a second vessel portion toward a vessel outlet. During at least a portion of the movement through the second vessel portion, the articles is contacted with a second fluid medium. In certain implementations, each of the first direction and the second direction are vertical.
