What home appliances use the most power?

Appliances use varying degrees of energy but have you ever wondered how much power each of your appliances use? Or how much it is costing you to run each of these appliances per year?

We have taken the time to work out the figures, so you don’t have too.

Appliance	Av. Wattage	Average use per day / hours	kWh/ year	Cost
Kettle	2000 W	16 minutes	194.67 kWh	$60.00
Oven	2400 W	2 hours	1752 kWh	$539.97
Electric Heater	1500 W	4 hours	2190 kWh	$674.96
Television	138 W	4 hours	201.48 kWh	$62.10
Split system	10000 W	3 hours	10950 kWh	$3374.79
Microwave	1000 W	20 minutes	120.45 kWh	$37.12
Central AC	3500 W	3 hours	3832.50 kWh	$1181.18
Washing machine	500 W	2 hours	365 kWh	$112.49
Clothes Dryer	3000 W	2 hours	2190 kWh	$674.96
Hairdryer	1500 W	30 minutes	273.75 kWh	$84.37

Vacuum	1400 W	1 hour	511 kWh	$157.49
Dishwasher	1800 W	2 hours	1314 kWh	$404.97

This results in a total spending of $8,040.03 a year * on energy.  

Usage timings

When you have a solar panel system you have the luxury of being able to time when to use certain appliances. When possible try to use the high voltage appliances during the day when the power can come directly from your solar system. You can do this by using a smart plug or the timer settings on the appliance.

Solar Batteries

Energy prices are increasing and having a solar panel system can offset some of this cost. However, homeowners are still finding that they are paying considerably more for energy than they are getting back from their suppliers for feeding in their excess energy during the day. A solar battery lets you store that excess energy so that you can use it when you need it most.
