End result:
The sensor cable from the collector header should be taken underneath the roof tiles and
down to the storage tank. The flow and return pipes must at all points slope down
towards the storage tank. This is essential in order for the water in the collectors and in
the pipes to flow back to the storage tank when the pump is not running. Ensure that
there is no tension on the flow and return pipes or leakage may occur. The red flow pipe
should be insulated along the whole of its length, using the pipe insulation provided. The
blue return pipe should be insulated only above roof level. The sensor cable can be
extended if necessary using a two wire cable.
