Abstract

A dual-heat-source gas water heater comprises a combustion-heat heat exchanger (2), a heating-heat heat exchanger (6) and a selecting valve (9), wherein the selecting valve (9) controls on and off of pipelines of the combustion-heat heat exchanger (2) and the heating-heat heat exchanger (6). The dual-heat-source gas water heater is capable of utilizing a heating heat source to produce hot water by the aid of the heating-heat heat exchanger (6) and utilizing gas combustion heat energy to produce the hot water by the aid of the combustion-heat heat exchanger (2).

Description

technical field [0001] The invention belongs to the field of water heaters, in particular to a dual heat source gas water heater. Background technique [0002] In the prior art, in regions with slightly cold weather around the world, there will be central heating in the cold season, and the heating heat source is delivered to the user's home for use, and the use cost is relatively low. Water heater is a necessary product for people's life. Most of the existing technologies use gas combustion to generate heat source, and then generate hot water through heat exchange, but the use cost is relatively high. For this reason, a kind of dual heat source gas water heater is specially developed for regions with central heating in cold seasons. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas water heater with dual heat sources, which has the characteristics of producing hot water by using the heat source for heat exc...
