Condensation type gas heater

The invention discloses a condensation type gas heater. The condensation type gas heater comprises a water path system, a condensation heat exchange device and a water cleaning device. The condensation heat exchange device is provided with a condensed water outlet. The condensed water outlet is connected with the water path system to recycle condensed water. The water cleaning device is connectedbetween the condensed water outlet and the water path system to treat condensed water. According to the embodiment of the condensation type gas heater, the condensed water is treated through the watercleaning device, and then the treated condensed water is recycled to the water path system so as to be used, so that the problem of emission of condensed water is fundamentally solved, the condensedwater is recycled, and the heater is more convenient and safer to install and use. 本发明公开了一种冷凝式燃气加热器，所述冷凝式燃气加热器包括：水路系统、冷凝换热装置和水清洁装置。其中，所述冷凝换热装置具有冷凝水排出口，所述冷凝水排出口与所述水路系统相连以回收利用冷凝水；所述水清洁装置连接在所述冷凝水排出口和所述水路系统之间以处理冷凝水。根据本发明实施例的冷凝式燃气加热
