Abstract: A fuel saving food cooker and water heater arrangement includes an inner tank body and an outer tank body to define a water chamber between the inner and outer tank bodies, a heat chamber within the inner tank body, a bottom heat inlet communicating with the heat chamber for operatively connecting to a steam outlet of a food cooking apparatus, and an upper heat outlet communicating with the heat chamber, wherein an excessive heat from the food cooking apparatus is guided to pass to the heat chamber through the heat inlet to heat up the water within the water chamber.

Abstract: A fuel energy saving water heater includes a food cooking apparatus, a heat collecting tank, and a water guider. The heat collecting tank includes an outer tank body and an inner tank body spacedly supported within the outer tank body to define the water chamber between the outer tank body and the inner tank body. The water guider is thermally communicated with the heat chamber, having a water chamber, a water outlet communicating with the water chamber, and a water inlet for operatively connecting to a water source. When a water flow is guided to pass through the water chamber from the water inlet to the water outlet, the water flow is heated by the excessive heat therewithin at a predetermined water temperature.

Abstract: 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.
