Used hot water tanks serve the same purpose as new hot water tanks, and both heat cold water. Used hot water tanks not only heat water, the tank also stores hot water waiting for use. The used hot water tank usually has delivery pipes and a water supply on top.
When purchasing used hot water tanks, it is important to inspect the tank for rust, holes, corrosion and other defects to essential parts. These tanks are generally made of steel and feature insulation, which helps keep water warm during heating cycles. Used tanks may have damaged insulation or a corroded anode rod, which can prevent the tank from heating water properly.
