The energy saving stove water heater includes a heat collecting body, with a tubular shape, having a water chamber surrounding with a heat source of the cooking stove, a water pipeline operatively communicating with the water chamber, and a top opening aligning with the heat source. Therefore, when a cooking tool supports on the heat collecting body at the top opening thereof, the heat source of the cooking stove is arranged to generate relatively high heat energy thermally transferring not only towards the cooking tool at the top opening but also towards the water chamber to heat up the water therewithin.

A horn connectable to an energy source to amplify ultrasound displacement is connected to a transmitter formed of material having relatively high mechanical Q for transmitting ultrasonic energy therethrough at a frequency f, the transmitter having a horn-shaped configuration of length that is a multiple of a half-wavelength. lambda. /2, and preferably this horn-shaped configuration is comprised of multiple horn segments, each of a length substantially equal to a multiple of. lambda. /2, where. lambda. =c/f (c is the speed of sound in the high Q material). The transmitter has a proximal end of cross-sectional diameter D. sub. 1 connected to the horn and a distal end of cross-sectional diameter D. sub. 2, where D. sub. 1 >D. sub. 2. Ultrasonic energy transmitted through the transmitter drives a tip which is coupled to the transmitter by means of a flexible connector.
