Running Cost Calculators

Introduction

Need to calculate the electricity costs of a water garden? Our running cost calculator will help you know how much you will
pay for your pond electric usage for an existing water pump. You can also use our running cost calculator to know how much
will you spend on electric bills when you choose a certain pump for a new pond or water garden. All you have to do is to fill
in the required information about your pump/appliance, click the calculate button, and see the calculation results.

Steps

You will need 3 values to calculate your pump/appliance’s running cost:

• Watts - the power rating or wattage can be usually found in the pump or appliance. You can also calculate
  this by multiplying the appliance’s Amps with its Volts (Amps x Volts = Watts)
• Time – this is the number of time, in hours, when the pump/appliance is used or is turned on per day. If your
  time value is in minutes, divide the minutes by 60 (minutes / 60) to get a value expressed in hours.
• Cost per KWh – the cost per KWh can be seen in most electrical bills or can be asked from your electrical provider. This is the rate on which your electrical provider charges you per kilowatt you use hourly.




This works by dividing watts by 1000 (Watts / 1000) to get the kilowatts. Then, kilowatts will be multiplied to hours/time (KW x t) for the Kilowatt hours (KWh). Finally Kilowatt hours will be multiplied to cost per kilowatts for the cost of running your water garden. 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¢ to use an AQUAGARDEN Cyclone 2500 (80 watts) for 24 hours. Based from the results, a lower energy pump will consume less energy than an ordinary pump would. By multiplying the 13.38 cents you saved by using a low powered pump to the number of days in a year, you will see that you would have saved around $48.84 per year.
