Waterco is now offering testing facilities for suppliers and manufacturers of swimming pool pumps who would like to provide energy efficiency star ratings on their products. The recently-published, voluntary Australian Standard AS5102* for star labelling applies to all residential swimming pool pumps that are imported or manufactured in Australia.
"Swimming pool pumps account for almost 80 per cent of a pool's energy use and both the environmental and money saving benefits of having a reliable energy star labelling program have long been recognised," says Bryan Goh, group marketing manager, Waterco Limited.
"Waterco has worked closely with the Department of the Environment, Water, Heritage and the Arts (DEWHA), Australian Standards and other key stakeholders to establish this new standard for the swimming pool industry. Developing and investing in the necessary testing tools that meet Australian Standard's stringent requirements was a natural next step," he says.
Waterco's test rig has been designed and constructed in consultation with Peter Seebacher, a specialist consultant to Australian Standards on the energy labeling program. The rig is capable of testing from 40mm up to 150mm ports and consists of sound-measuring hardware and customised software for testing efficiency and accuracy.
In order to determine energy ratings, a minimum of three units of the same model are required for testing at any one time. In some circumstances, where the performance of three pumps is too variable, additional units may be required. The cost per single pump model starts from $1500.00 + GST**.
Once tested, Waterco will provide the results in accordance with AS5102 and will calculate the pump's star rating. The labels are then to be displayed at the time of sale.
"Energy efficiency star ratings are an important step for the industry, finally bringing us into line with the wider electrical appliances industry. Given that there are moves to make this standard mandatory from 2011, we encourage suppliers and manufacturers to comply as soon as possible," says Goh.
Pump star rating: the process
The pump star rating process consists of measuring the input power (PD), head (HD) and sound power (LWD) for various flows (QD) for each pump unit tested, then calculating the energy efficiency and the projected annual energy consumption (PAECD) of the unit. The energy efficiency is then used to calculate the star rating index and the star rating.
The final Waterco test report will then contain the following information:
Model name design (single-speed etc)
Efficiency (EFD(av)) - (L/Wh)
Flow (QD(av)) - (L/min)
Head (HD(av)) - (m)
Power factor (PFD(av))
Noise (LWD(av)) - dBA
Projected annual energy consumption (PAECD(av)) - kWh/y
To organise testing, suppliers and manufactures should contact Bryan Goh at Waterco Limited on firstname.lastname@example.org or call 02 9898 8643.
