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
