Gas heating water heater with smoke temperature compensation structure

Technical Field

The utility model relates to the technical field of heating equipment, in particular to a gas heating water heater with a smoke temperature compensation structure.

Background

The heat exchanger of the wall-mounted boiler product is mostly formed by red copper welding, copper is a relatively active metal, condensed water is extremely easy to corrode, and is limited by energy efficiency requirements and the design conditions of the whole boiler, and the wall thickness of the heat exchanger cannot be too thick, so that most of non-condensing wall-mounted boiler products are afraid of corrosion of the condensed water.
