Average consumption of home appliances
Here we give information about the power consumption of several home appliances, which use either gas or electricity.
Electric home appliances
When you purchase an electric appliance, the power consumption will usually be written on it (either on the box, or on a sticker on the appliance itself). This will indicate what power it is consuming when in use. It will not indicate the average power consumption over time but rather the power consumption at full power. For example, a microwave oven will consume a lot of energy when turned on, but none when turned off. And even though it consumes a lot of power when functioning, you might only use it a few minutes a day. In the following table we show the power consumption (in watts), and the energy in consumes every day on average (based on the typical amount of time each appliance is turned on every day).

Gas home appliances
There are less appliances in your home which will use gas.
| Appliance | Power (BTU/hour) | Usage per day | Energy per day (BTU/day) |
|---|---|---|---|
| Space heater | 80,000 | 5 hours | 400,000 |
| Water heater | 40,000 | 2 hours | 80,000 |
| Stove | 20,000 | 0.25 hours | 5,000 |
| Baking oven | 16,000 | 0.5 hours | 8,000 |
| Grill oven | 12,000 | 0.5 hours | 6,000 |
| Gas clothes dryer | 22,000 | 2 hours per week = 0.29 hours / day | 6,380 |
| Gas fireplace | 25,000 | 1 hour | 25,000 |
The amount of hours each appliance is used per day is very subjective. Each customer may use these appliances differently, depending on habits, the size of the house, or the number of inhabitants. In addition, some appliances may be used less if other appliances are used more. For example, if a customer bakes more often than he/she cooks on the stove, the values in the table will change.
