FIELD: heating systems. ^ SUBSTANCE: gas water heater includes cylindrical housing, inside it there installed is furnace with water jacket above which there are holes from flue gas channels and furnace. Connection pipe installed above the hole in water jacket attaches flue gas channel in a hydraulic manner to water chamber which is located under housing and connected via outlet connection pipe to consumer. Holes made in upper part of water jacket are made so that their diameters are enlarged towards edge wall of housing, and they are located in rows and offset relative to each other by 3d (d - diametre of the biggest hole). ^ EFFECT: possibility of using the device at various modes with optimum efficiency coefficient and improved water quality. ^ 2 dwg, 2 cl |
