Consequently, buying efficient products can save money over the years they are owned and there are a variety of tools to calculate their running costs. The ENERGYWISE running costs calculator, supplied by EECA (Energy and Conservation Authority), can be used for most whiteware and heat pumps to find out how much they will cost to use. Alternatively, energy consumption figures can be found on the energy ratings labels many of the appliances have. Not included in the calculator are appliances that use electricity at a constant rate when in use, such as some electric heaters, kettles, toasters. However, EECA supplies a simple calculation. The running cost of an electrical appliance is determined by its capacity, expressed in watts (W) (1000W=1kW); the electricity tariff, typically about 26-cents per kWh for normal residential electricity supply; and how long the appliance is used for. To work out the running cost: ■ Take the capacity in kilowatts (if it is in watts, divide by 1000 to get kilowatts). ■ Multiply by the electricity tariff if you know it, otherwise use 26. The answer is how much it costs to use the appliance in cents per hour. ■ If the appliance is used for a period of time, multiply by the number of hours to get the total and don’t forget the answer is in cents. For example, a 2.4kW heater run for four hours a day at an electricity cost of 26c per unit will cost 62.4c an hour to run, or $2.50 to run each day. For more complex appliances that use a varying amount of energy over time, such as a heater with a thermostat or a stereo, a simple electricity metre can be used. They are available from hardware stores and go between the wall socket and a plug-in appliance. They measure how much power the appliance is using at a moment in time and can also track energy consumption over longer times. ■ The ENERGYWISE running cost calculator can be found online at www.energywise.govt.nz.
