Household running costs
Typical running costs for household appliances
The amount of power an appliance uses is determined by its wattage. 1000 watts equal a kilowatt. When you run a 1000 watt appliance for one hour, you use one unit (kilowatt hour) of electricity. One unit of electricity will run a 2000 watt space heater for 30 minutes or a 100 watt bulb for 10 hours. The following table sets out approximate running costs based on Meridian Energy’s Prices as at 15 March 2009. All prices include GST.
Electricity used by hot water cylinders will vary according to the size of the cylinder, amount of hot water used, the thermostat setting, the temperature of the incoming water temperature, and the insulation of the cylinder.
