In this particular regard, stainless steel is significantly worse than copper, and having stainless steel heat exchangers for water heaters is usually a practice that requires less. In the face of the Air Dryer series BPHE following industry status, AO Smith provides his own opinion. They introduced lots of heat exchangers using stainless steel water heater products, and ranking with high-end products. According to the AO Smith staff, the metal heat exchanger has many merits, including longer life, up that will 15 years, and strong plaque created by sugar and corrosion resistance. The first element of the actual heat exchanger is heat conduction, that's directly related to the user's experience in with the water Copper brazed plate heat exchanger heater product.. Its understood that water heater product technology isn't complicated, its core component will be heat exchanger, the role would be to quickly and efficiently exchange the heat generated by gas combustion into your water, cold water absorbs heat when flowing throughout the water pipe in the heating exchanger, become Hot water to get users.
