An instant gas water heater features a water circuit (4) fed with water contained in a thank (7) and heated by another, preferably natural, heat source; a gas burner (11) for generating hot fumes; a heat exchanger (10) for transferring heat from the hot fumes to the water circulating in the water circuit (4); a gas adjusting device (24) for adjusting the gas flow rate to the gas burner (11) as a function of water flow rate in the water circuit (4); and a partializing device (20, 21) for partializing the gas burner (11) as a function of the water temperature in the water circuit (4) upstream from the heat exchanger (10). |
