List of the Power Consumption of Typical Household Appliances
If you are attempting to find good info on a building code, then the internet is the perfect place for you to go. Whether your looking for a home inspection or more information about building contractors, we can help you!
Turn that TV off if you're not watching it! It's wasting electrically!
How much electricity is it really wasting?, and would it not be better to switch off the 4 lights in the room?
The best way to compare the cost of running different appliances is to look at their power consumption, which is measure of how much power they use in Watts. The following list points out typical values for the wattage of some devices you would find in your home so that you can compare them.
Lets start with the easy ones ...
- 60W light bulb - 60W
- 100W light bulb - 100W
Now some more common appliances...
- Toaster : 800-1500W
- Microwave : 600-1500W
- Dishwasher : 1200-1500W
- Washing Machine : 500W
- Vacuum Cleaner : 200-700W
- Iron : 1000W
- Electric Mower : 1500W
- Clothes dryer : 4000W
- Ceiling Fan : 10-50W
- Table Fan : 10-25W
- Electric Blanket : 200W
- Hair Blow dryer : 1000W
- Electric Shaver : 15W
- Laptop Computer : 20-50W
- Desktop Computer : 80-150W
- TV (19" colour) : 70W
- Clock radio : 1W
- 9" disc sander : 1200W
- 3" belt sander : 1000W
- Fridge / Freezer : 500W
- 25" colour TV : 150W
- Electric Kettle : 2000W
- Power Shower : 240W
An important point is also to bare in mind the length of time for which the device will be used. For example an electric blanket may be used for 2 hours, but a hair drier for 5 minutes. Therefore the blanket uses 200W * 2 hours = 0.4kWh. The Hair drier uses 100W * 0.0833hours = 0.008333 kWh. So using the blanket costs roughly 5 times as much as the hair drier.
All values reported here are estimates, you should check the appliance labels or literature to find out the correct power consumption.

Starting power consumption is really only worth considering if there is a large motor (motors generally draw 6 times their rated current on start-up) such as a pool pump or refrigerator. And will not so much affect the power consumption as at will the requirements of the off-the-grid inverter which will have to be capable of providing the max expected demand of the installation (rated current of the biggest motor x 6). I have just done an excel spreadsheet to calculate your monthly power bill by appliance to help find what appliances use the most power. If anybody is interested you will find it on my website www.ets.net.nz

Starting power consumption is more difficult to measure and has less documentation. If anyone knows the typical transient consumption for any of the above appliances then please let us know and it will be added.

Many people are beginning to explore "off grid" systems and those people need to consider both the "running" power consumption and the "starting" power consumption. You omitted the latter.
It would be helpful if you included the starting consumption in your chart.
