Home Appliances Power Consumption Guide

Have you ever wondered why the running costs for home electricity are so unpredictable?

Assuming your household has maintained a consistent routine, your power consumption should not deviate from a specific figure. Yet for some reason, your billed costs probably continue to fluctuate up and down without an exact cause.

The confusing trend can be answered via a method to estimate your electricity bill rates.

The first step begins with isolating the factors most likely causing the fluctuations in the measurement of electric uses in the household.  

Factors such as broken meter readings and even a neighbour stealing power from you are big possibilities. However, before you can address them, you need to figure out how much you’re spending on household appliances.

Finding this figure can allow you to subtract the running cost from your electric bill and single out the outlying odd factors.

Identifying the watts consumption of each electrical appliance is an ideal starting place. The wattage values will let you calculate an accurate figure. Protip: An online electricity bill calculator can speed up the process significantly.   

Oftentimes you can find these wattage values on the appliance itself. Sometimes it is carved or imprinted somewhere on the unit. On certain occasions, they might be found on a tag or an online listing.

Another good reason for finding the unit’s wattage is to rule out potential safety hazards. Products that generate excessive wattage might necessitate maintenance or replacement.

You can check an appliance unit’s precise wattage when you use a wattage meter after switching on the appliance.

How Much Power Does Your Appliance Consume?

Learning precisely how much power your household appliances will consume will have several useful applications.

Besides concerns about safety hazards and electric bill costs, knowing the wattage can help you plan for aspects such as setting up your house’s wiring and a more suitable location to handle your wattage needs. 

Advertisements for supposedly better and more efficient models of desired electrical appliances will also be less likely to mislead you in the future.

Electric Oven

Electric Oven

Of the many household appliances that eat up power, a good many of them are found in the kitchen.

Electric ovens cook different meal types and pastries. They, therefore, need to be able to crank up to 425 Fahrenheit degrees, requiring over 1000 to 5000 watts depending on the unit.

The average electric oven will thus generate at least 2400 watts per hour, usually resulting from the use of medium to high heat.

Crock Pot

Crock Pot

Crock Pots are known for being some of the most energy-efficient examples of electrical appliances out there. There is a tradeoff, however in terms of the number of hours required.

Crock pots will run for eight hours for what electric ovens can accomplish in one. Therefore, since the average crockpot uses 200 watts per hour you need to calculate that accordingly times eight each time.

Toaster

Toaster

Toaster wattages will often come in a diverse range between 800 and 1500 watts. Its wattage per hour will average around 1,200 watts.

Given the oven toaster’s limited mode of uses, it’s more likely to average even less than that for your electric bill. After all, the average household isn’t likely to use an hour’s worth toasting bread regularly except for special occasions.

Microwave

Microwave

Wattages for microwaves can depend on the microwave type. Compact microwaves will be somewhere between 500 and 800 watts, while the more regular sizes will range between 850 to 1800.

The modern microwaves will usually average at 1200 watts per hour when used for heating. During standby mode, it will average at 4 watts per hour, between 2 to 7 watts.

Refrigerator

Refrigerator

Unlike many of the other household appliances, refrigerators aren’t usually going to be put into standby mode or switched off. They will continue using a consistent amount throughout the day until their operation is interrupted.

The average fridge uses 100 watts per hour, but if it’s a large unit, it could be as high as 180. That translates to 2400 watts a day for smaller units and 4320 for large units.

Computer (Laptop and Desktop)

Computer (Laptop and Desktop)

When computing wattage costs, you need to differentiate between active and standby mode. During active mode, laptops will generate 200 watts per hour, while desktop PC’s will only use between 50 to 100.

Switching to standby mode will reduce wattage consumption to a third of those numbers. If the monitor screen is the only thing put on standby, consumption will only reduce by 15%.

Washing Machine

Washing Machine

Most washing machine models will use over 400 to 1300 watts per hour. Modern machine models (referred to as frontloaders) will usually be more efficient, using less water and energy for every wash.

Most modern models use about 90% of its energy just to heat up the water to wash the clothes. Therefore, we recommend washing in cold water to save on energy.

Television

Television

Calculating television wattage consumption is usually the most complicated factor. This is because the wattage is dependent on television type and size. Energy-saving features can also change the wattage output significantly.

For example, a 15-inch LED screen runs 15 watts per hour. An LCD screen of the same size will generate 18 watts while an equal-sized CRT unit will go up to 65.

As the size of screen sizes go up, so does the wattage at different rates. Thus, an average ballpark figure will usually depend on those two factors.

Electricity Saving Tips

Electricity Saving Tips

We recommend you try these options to keep your running costs down.

1. Unplug appliances when not in use – Although relatively simple to execute at the moment, the practice is often easy to forget due to the perceived inconvenience of having to plug and unplug repeatedly.

Pasting a sign next to each appliance can be an easy way to ensure that you won’t forget or be tempted to drop the routine.

2. Consult each appliance’s manual thoroughly – Most modern electrical appliances have energy-saving features that are easy to overlook. These can include preset timers that can either switch off or set your device to hibernate after an idle period.

3. Install an energy-tracking solution – If you feel you need a more obvious constant reminder, getting an energy-tracking device can be useful. Some apps will even allow you to hook directly into an outlet and provide you with updates about your power usage.

4. Consult a handyman or electrician – Who better to advise you on your power usage than the one who maintains your household wiring? In terms of safety and conservation, their perspective on your current and future appliances will be invaluable.  

After inspecting your household, they’ll be able to give you tips on any internal modifications that can make your living space more energy efficient.

5. Weatherize your Household – Escaping heat, or cool air can cost you unknowable amounts. You can address these problems by finding the holes, cracks and openings between windows and vents.

We recommend you hire a professional to help you perform a thorough reinforcement.
