Cylinder Loading System (CLS)
Most unvented cylinders use a heating coil
to heat up the cylinder. The CLS technology
replaces the coil with a plate heat exchanger.
A DHW pump circulates the cold water from
the bottom of the cylinder, through the plate
heat exchanger and puts the hot water back
to the top of the cylinder.
