Running Cost Calculators

                             
Electric usage is measured in kilowatt-hours.
 1 watt-hour is the equivalent of 1 watt of power used for 1 hour.
1 kilowatt-hour is the equivalent of 1000 watt-hours used for 1 hour

Three values are needed to calculate the cost to use an appliance:

• The power rating or wattage of the appliance. This is found on the appliance e.g. 50W or 1800W.
• The time the appliance is switched on in hours (or minutes ÷ 60)
• The cost per KWh.


1. Appliance wattage ÷ 1000 = kilowatts (kW)
2. Kilowatts × (time appliance is switched on in hours) = kilowatt hours (kWh)
3. Kilowatt hours x cost per KWh is what you pay for that appliance to run.

 

  
     
  RUNNING COST CALCULATOR
Enter the details of your pump and/or UVC, and daily use below to work out how much it costs to run:
Wattage of Pump or UVC
How long is it used each day? Hours
Cents per KWh -
as shown on your electricity statement
Cost per day $ 
per quarter $ 
per year $ 

 



 
Example 1:
AQUAGARDEN Cyclone 2500 (80 watts) on for 24 hours where the cost per KWh for electricity = 13.94¢ (.1394)

(80 ÷ 1000) × 24 =  1.92 kWh used

1.92 kWh × 13.94¢ =26.76¢

This means that it costs 26.76¢ to use a OASE Neptun 3000 Eco (40 watts) for 24 hours.

 
 
Example 2: OASE Neptun 3000 Eco (40 watts) on for 24 hours where the cost per KWh for electricity = 13.94¢ (.1394)

(40 ÷ 1000) × 24 = .96 kWh used

.96 kWh × 13.94¢ =13.38¢

This means that it costs 13.38¢

As you can see, using a low energy pump in place of an ordinary pump will save you 13.38 cents every 24 hour period your pump is on..

Multiply this for a years worth of running and you are saving $48.84 per year.
