Requirements for a valid claim Claims must be submitted for installed systems only Houses must have running water and electricity Proof of electric connection and address required Roof structures must be able to support the weight of the system System must be registered on the Eskom SWH programme Supplier and installer must be registered on the Eskom SWH programme for that particular system Full customer documentation to be submitted per installation and per home Claims will only be paid up to max quota allocation per month/company 9

Claim irregularities No installations and false documentation Incomplete installations Duplicate/triplicate claims on barcodes/addresses/customer details Non-existent addresses Incorrect system installed Non performing systems Physical address validation for audits 10

Quality of installations Most common technical audit issues 1 Loose bolts and nuts on the frame work 2 Plastic pipes used on the outside instead of copper pipes 3 Insulation not installed on the water pipes 4 Eskom barcodes not used on the equipment/customer DB 5 Water proofing not done properly resulting in water leaks at the geyser and pipe work holes left open 6 Water pipes not supported 7 Tank and collectors not facing the optimum direction/angle 8 Incorrect timer setting, SWH System and pipes not earthed properly 9 Water pipes not connected 10 Systems not properly/safely secured to roofs 11 Mixing valves and stop valves not installed 12 No collars on filler tanks 13 Filler tanks leaking & filler tank valves not working

Poor installations illustration Filler tank leaking excessively Drilled hole left opened Filler tank with no collar Filler tank with no overflow pipe & lid Plastic pipes used and poor insulation Loose & plastic pipes 12

Poor installations illustration Unit not properly/safely secured to roof Skew installation/plastic pipes/ loose pipes/ no insulation System leaking Unit not properly/safely secured to roof Roof structure collapsing due to weight of unit & no support Plastic pipes outside building 13

It is not all doom & gloom Installation quality is improving! 14
