The pumping station serves several purposes. It makes self build installations easy as it collects together all major components into one area making for a much faster and robust install also the majority of compression fittngs can be connected and checked at the pumping station. Also any excess air/gas that may be introduced into the system when installing the solar water heating system or maintaining, can be removed using the air bleed. The pressure in the circuit between the sola collector and the cylindetr can be restored back to its original level of one bar using the hand pump and gauge.
