Pump testing facilities now available
Waterco is 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 labelling
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 (+
GST), although Waterco reserves the right to
increase the test charge accordingly, if the
individual pump test exceeds one hour.
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.
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 (PA-
ECD) 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)
• Solar Pool Heating
• Pool Heat Pumps
• Pool Blankets/Rollers
• Automatic Pool
