 _Plumber demonstrates they mysteries of heat transfer coils in hot water cylinders by cutting away the side of the cylinder. Coils can transfer heat to or from the cylinder. So for example, hot water from solar panels can transfer heat to the cylinder via a coil; but also, hot water in the cylinder can transfer heat to water in a coil for the central heating. A cylinder can have one, two or more coils._
