Hot water coils are one of the simplest parts to an HVAC unit, but it can be important to know the parts so you know what type of connections and where they need to be located. Similar to chilled water coils, If and when a coil is to leak it usually happens in the copper u-bends. But with hot high pressured water, it will first leak at the weakest place which can be on a return bend or in the middle of the coil. When patching a leak in the middle of the coil it will significantly destroy that area causing the coil to lose a great deal of efficiency.
