Abstract
A portable water heater includes an inner bracket and a thermostatic chamber. A burner and a heat exchanger are arranged in the inner bracket. An upper end of the heat exchanger is provided with a fume collecting hood. The burner includes multiple fire rows arranged side by side, and the fire rows are connected to each other through a gas-distributing rod. The gas-distributing rod is provided with a segmented self-priming valve. A gas-regulating valve is provided on a gas inlet pipe. An inlet end of an internal heat-exchanging pipe of the heat exchanger is communicated with a cold water feeding pipe. The thermostatic chamber has a water inlet connected to a hot water delivering pipe and a water outlet connected to a hot water discharging pipe, and a connecting pipe is provided between the cold water feeding pipe and the hot water delivering pipe.
