Power consumption (watch the watts)
|
The average cost of power
in Australia is about $1.65 per watt per year, so a 10 watt
pump / light etc,
will cost about $16.50 to run 24 hours a day for a year. (31cents per week)
If running 24/7
To calculate
yearly cost of operation: Watts divided by 1000 x the price of electricity in $
per kilowatt hour x 24 hours x 365 days (assuming continuous operation)

Pond and sump pumps are cheap to run
|

Pond
pumps are designed to pump water at low pressure and use minimum power.
For
example, a pond pump pumping 15,000 litres per hour uses
250 watts
of
power, while a high pressure head pump at the same volume uses about
700 watts,
an increase of 450 watts, an
approximate cost increase of $742.50 annually.
Look on the pump charts, every pump has a 24/7 electricity use cost
