Energy saving stove water heater

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.
