2. Heat the liquid
Water: Stainless steel 304 material can be used for heating tap water, stainless steel 316L for drinking water, and water heating with serious impurities can use the coated anti-corrosion and anti-scale electric heating tube developed by Feiyu Electric Heating
Oil: Stainless steel 304 is used for oil heating, and electric heating tubes made of carbon steel can also be used if you pursue low cost
