Purge Pump For Ground Source Heat Pumps

Kensa recommends the Clarke SPE1200SS (part no. 051012200) to purge ground arrays, in order to remove air in the pipes to avoid the heat pump system freezing. The pump comes ready to take a 1” BSP fitting.

As a kit, Kensa Heat Pumps provides 2 x 1” BSP Male Iron to 28mm Speedfit connectors. This will enable the pump to be connected to the slinky manifold using 28mm Speedfit or similar pipes and elbows.
