If you’re a busy person who doesn’t have time to prepare meals, a slow cooker can assist you in ways you never expected.

Suppose you’re a college student who has to balance part-time employment and classwork, or a recent bachelor trying to establish yourself in the competitive job market without enough time to prepare a nutritious breakfast or dinner. Here, a slow cooker comes to your aid. You can just add all the required ingredients the night before and set it in a way that the food will be ready in the morning. So, when you come back from your classes or job, you can sit and relax with a warm meal.

When we think of electrical gadgets, many of us imagine that they use a lot of electricity. However, in reality, a slow cooker consumes less amount of power than many other home appliances. So, how much electricity does a slow cooker use?

In this blog post, we will discuss just that.

Electricity Usage of A Slow Cooker

It’s financially necessary to know how much energy you are consuming in your home and kitchen and whether these day-to-day appliances are increasing your energy bill alarmingly.

If you’re using a slow cooker, you already know that these don’t require much electricity. The insulated body and lid don’t let the steam come out, which keeps the power usage lower. A meal that takes 8 hours to be cooked, needs 1.2-1.7 kWh. If you make a medium meal for six hours, it roughly needs .9 kWh or 150 Watts per hour. You just need to plug it in a socket where it will be provided with a 120 volt AC.

If you are really eager to know the cost, do a simple multiplication using this equation Cost = power (kilowatt ) x cost of one kWh (Dollar/[the currency of your country]) x the time taken (just the one-off meal, or over a week or month.) If you ponder over it, I think you will find it worth giving slow-cooker a shot.

Slow cooker power/wattages :

The power usage varies from model to model as well as the heating setting. The recent models will fall between 70-250 watt ranges. If you are not familiar with slow-cooker just know that there are two heating systems. High and low, respectively, ranging from 70-150 watts and 150-250 watts. So owning a slow-cooker doesn’t contribute much to your electric bill. Not only that but also the high efficiency of a slow cooker helps to save nature.

Slow-Cooker electricity using calculation

We have mentioned the formula above. But if you hate math( who loves math anyway?!) We are here to take you even further. It’s simple. Take the lowest setting of your cooker and watts and then multiply by how many hours you used your cooker.

For example: if your cooker takes 90 watts per hour in a low setting, it will take 450 watts in five hours. Easy right?

Now let’s do a bit of complicated math (nothing Einsteinian). For this part, you need to know the price of 1 kWh in your country. In Australia, 1 unit costs roughly 0.224 USD for households. (b So if your cooker takes 450 watts to cook a meal it will cost 0.450×9=0.1008 USD. If you cook twice a day, then the monthly expense will be (0.1008×2×30)=6.048 US dollars. If you find it expensive, wait till we compare it with other kitchen appliances.

Electricity Usage of a Slow Cooker in Comparison to Ovens

At this point, you must be wondering why other electronic kitchen tools are so demanding. Well, everything comes with its own distinction. The key difference between an oven and a slow cooker is time. Though it completely depends on the recipe you are making, the cooker takes a longer time than the oven. Normally the average time a cooker takes is 5-10 hours. Both of these also differ in size, cooking method, and consistency.

If you compare time

  • One to one and half hours on high in a slow cooker is equivalent to 15 to 30 minutes in the oven.
  • Six to eight hours on low is equivalent to 35-45 minutes in the oven.

But when it comes to energy consumption, no one can beat a slow cooker ( in a positive way obviously). The reason behind slow cooker’s use of very little energy is: that they cook at 170-300 degrees F. It’s possible because the lid prevents steam and heat from escaping. On the other hand, it takes a longer time to heat the ample space of an oven, as a result, they cook at a far higher temperature(ranging from 325-500 F, based on what ingredients you are cooking).

On average, slow cookers use 150-210 watts whereas an oven needs between 1000-5000 watts of energy (2400 on average). Big difference, right?

For instance, a cooker needs 0.8 Kwh to make roasts and quick soups, while electric ovens use nearly 3 Kwh for the same recipe. So, if you are looking to slash your bills, ovens are not a wise option.

In another real-life example, it will cost you 3.57 dollars to cook a slice of 6-pound pork in an oven and only 40 cents in a slow cooker. The rest of the decision is yours.

Energy Efficiency of Slow Cookers

If you’ve got a modern slow cooker for yourself, you know these are designed with an in-temperature sensor for meats. This will automatically switch the pot to a warm mood once the desired temperature is obtained. Also, it is manufactured to maintain a steady and continuous heat. This special design makes a cooker 90% energy efficient. If you are dying for maximum energy efficiency, invest in a slow cooker that is programmable. The timer setting allows switching between off and on, economizing electricity units. To get the greatest service for a long time, keep your slow cooker clean after each usage.

So we have discussed all the common features of a slow cooker and the output it gives in the world of spices and taste. We hope this helps you make a more informed purchasing decision, and if this isn’t enough, please read our extensive slow cooker buying guide.
