Copper material is suitable for the water quality partial alkalinity. Therefore, if the water quality is too acid, copper cannot be used. If customers find that red copper and 304 stainless steel are corroded in water, they can try to use Incoloy 800, which is heat-resistant, corrosion-resistant and oxidation-resistant. Package: 1PC x Heater, 1PC x Cap, 1PC Silicone Gasket Notices: 1) Water/oil heater, can not be dry burning, heating in oil should be kept below 300. 2) Since the heating wire in the heater is made of OCr25A15 and has magnetism, it is normal that the element can be adsorbed by the magnet. 3) Some heaters may have defects, such as welds, stainless steel marks and polishing marks.
