The gas heater that this embodiment provided installs condensate water collection tank at gas heater's outer wall through hanging board 41, opens jam cover 7, through hose 3 with condensate water drain pipe 2 and condensate water collection tank intercommunication, gas heater normally works, and in its course of the work, the flue gas of production rises, is collected by collection petticoat pipe 62 back and rises to in the pipe 1 of discharging fume through interconnection connecting pipe 111 and exhaust connecting pipe 12, is discharged by the pipe 1 of discharging fume. When the flue gas flows through the smoke exhaust pipe 1, the smoke exhaust temperature is lower than the dew point temperature, and condensed water separated out from the smoke exhaust pipe 1 slides into the condensed water drain pipe 2 along the exhaust connecting pipe 12, the inner connecting pipe 111 and the water guide sloping plate 121. Assuming that the use environment is under the standard atmospheric pressure, the interior of the condensed water collection tank provided with the exhaust port 521 is also under the standard atmospheric pressure, and the pressure inside the exhaust pipe 1 is positive, the condensed water separated out from the exhaust pipe 1 is discharged into the condensed water collection tank through the hose 3 under the action of the pressure difference, and after entering the water inlet chamber 42, the condensed water enters the drying chamber 43 through the water through hole 421, and the drying agent automatically absorbs the discharged condensed water. Through the transparent tank body 4, the color change of the drying agent can be easily observed, the drying agent which has reached the water absorption saturation state is timely cleaned and replaced, the condensed water collecting tank is guaranteed to have continuous water absorption capacity, the problem that condensed water discharged by the condensed water drain pipe 2 cannot be timely treated is avoided, and random overflow of the condensed water is avoided. When the drying agent is replaced or the condensed water collecting tank is cleaned, the condensed water drain pipe 2 is temporarily plugged by the plugging cover 7, the gas water heater can be continuously used without stopping, and the temporarily stored condensed water part can be evaporated by the high-temperature flue gas of the smoke exhaust pipe 1. The water outlet end of the hose 3 can be blocked by the blocking cover 7, and when the condensed water collection tank is cleaned, the water outlet end of the hose 3 is blocked by the blocking cover 7, so that the hose 3 also has a temporary storage function. The comdenstion water that the comdenstion water collection tank produced the gas heater carries out timely collection and absorption, avoid the comdenstion water to be detained inside the water heater, or flow to the water heater outside at will and produce pollution and corruption, improve gas heater's life, effectively solve the unable timely problem of handling of the comdenstion water of discharging to the gas heater outside, the comdenstion water in the comdenstion water collection tank is cleared up to convenient to detach simultaneously, help preventing to the corruption destruction of gas heater and other equipment, improve gas heater's convenience in utilization and security.
