Slow Cookers carry out the liberty to cook meals while focusing on other daily tasks, however how much power does a sluggish cooker use and how does this compare to other appliances such together an electrical stove or oven?

When operation for 8 hours on the short setting, a common slow cooker will certainly consume around 1.44 kW/hours the electricity. Over there are number of variables that affect the overall power consumption of a sluggish cooker. However generally, a slow-moving cooker is an energy-efficient different to an electrical stove or oven.

There are 4 areas we will check out further come answer how energy effective using a slow-moving cooker have the right to be and also how much they cost to run (compared come a stove/oven).

Before we acquire into it, together a basic safety note, always be sure to follow said recipe settings and also adhere come the safety instructions of your specific slow-cooker.

How Much electrical energy Does a slow-moving Cooker Use?

Calculating the electrical energy use the a slow-moving cooker relies on numerous variables including temperature setup (low the high), term of cooking, and also the dimension of your slow cooker.

Let’s begin with a rapid overview of how power intake is measured, then we’ll perform the math for a slow cooker example. 

How Power consumption is Measured

For most homeowners and also renters, the essential number for power usage is walking to it is in kilowatt/hours (kWh). 

This is the number the your electrical provider will certainly use when it comes time for billing and is a result of two other factors, amperage (current) and voltage (electrical “pressure”). 

Let’s briefly specify these terms for clarity:

Amperage (A) – The existing in an electric circuit. This considers both the volume and also flow-rate that the electricity.Voltage (V) – The potential electrical difference between points of an electrical circuit. This is essentially the basic “push” that moves electrical energy in a circuitWattage (W) – The power (P) calculation in an electrical circuit that results from both amperage and voltage.

Note: Resistance also plays a variable in electrical systems however we can afford come overlook this for the benefits of our sluggish cooker investigation.

A common means to think around this, is thinking about electricity together if it was water in a garden hose. Amperage would define the flow-rate of a specific volume of water v the hose and Voltage would explain the pressure exerted by the water. 

When multiplied together, we gain the Wattage (power) that the water generates. If we rise the pressure or present coming indigenous the hose, we view a higher resulting strength output.

The math (and an Example)

Now fine walk v the math using the low-cook estimate for a slow cooker.

Slow cookers run using a standard 120V outlet. They likewise operate in ~ a fairly low amperage, around 0.6 amps when maintaining food heat to 2 amps when operating in a high food preparation mode.

In bespeak to number out the strength output, we just multiply the Amperage and Voltage together using this equation.

 Amperage x Voltage = strength (Watts)

We will certainly assume the slow cooker is in the low-cook mode, which draws about 1.5 amps

Step 1: 1.5 Amp x 120Volts = 180W

A meter reading is done in kilowatts. 1 kilowatt is equal to 1000 watt in the same method that 1 kilometer is 1000 meters. To have actually our calculation be in kilowatts, we have to divide the product that the over equation by 1000 watts (1 kilowatt)

Step 2: 180 W / 1000 W = .18 kW

To acquire this amount into kilowatt hours, we then must multiply the product in example two by the moment that us were spend the electricity. Let’s say, for example, 8 hours.

Step 3: 0.18 kW x 8 hours = 1.44kW/hours

So we view that using a slow-moving cooker top top a low-cook setup for about 8 hours will use about 1.44 kWh that electricity.

Now, let united state take a look at at just how this translates into cost…

How much Does it price to run a slow Cooker?


At the time of creating this article, the average residential cost for electrical power in the united Sates is hovering approximately $0.13 every kWh. This would placed the expense of our theoretical power intake at the following.

 Step 4: 1.44 kWh x $0.13 = $0.19

So, we have the right to see the running a sluggish cooker for 8 hours on the low setting, would certainly cost about $0.19.

We have the right to follow the same procedures to calculation that using a slow cooker ~ above a high-cook setting for 8 hrs would cost about $0.25 ~ above average. 

However, making use of a high-cook setting would cut down top top the time required for cooking. So, if we only cooked for 5 hrs on high, then the price is basically the same, at around $0.19.

On paper, the expense efficiency between a high and also low setting switches (high becoming an ext expensive) if the high setting is supplied for more than 60% of the low-setting cook time.

Of course, there are plenty of variables the can affect this math, consisting of the size of your slow cooker and even the type of food being prepared. The is usually best to simply follow every little thing the cooking recipes calls for.

Are slow-moving Cookers energy Efficient?


As we observed above, sluggish cookers use a fairly low lot of power. This makes them a great alternative to stove-top and also oven cooking.

One that the an excellent benefits that the slow cooker is that much of its power is conserved. tiny heat is lost to ambient surroundings. In comparison, a stove-top burner might heat/cook the food quickly, however it also loses a many of energy to the air and also other aspects of the stove. 

Some slow-moving cookers, as well as many ovens, can additionally operate with what is known as a “duty cycle” in stimulate to assist conserve power use. This attributes in the same way that a heating system connects to a thermostat. 

The heating facet will periodically turn off and ago on to preserve a constant temperature. The appliance, then, isn’t constantly illustration energy the entirety time that it is on.

Is that Cheaper to use a slow Cooker or cooktop / Oven?

Calculating the expense of to run a stove provides the precise same an approach that we would use for a sluggish cooker. The main distinction is the the amperage and voltage the a range or cooktop is walking to be drastically greater than a slow-moving cooker. 

The cooking time, however, is typically less once using a range or oven. For this reason what type of numbers does this yield?

A residential electrical stove/oven, top top average, features using a 220 V outlet and also can draw in between 30 and 50 amps. Much bigger numbers 보다 our slow-cookers.

Using our equations native earlier, we watch that a stove drawing 30 amps would use 6.6 kWH if used continuously because that one hour. This would certainly cost about $0.88 per hour.

However, stove-top food preparation time is usually much less than a complete hour. If we assume we usage a burner for just 20 minutes, the total cost the that certain cooking time would be $0.29.

Using one oven additionally requires a higher electrical draw. The key variable to take into consideration with stove is that the main electrical attract is throughout its heater cycle.

While the range is heater to the preferred temperature, it will certainly be using a considerably larger amount of power than after the reaches the temperature and also the heater unit turn off off.

This makes the power usage of an oven less than what it would be merely doing the hypothetical math. To have a totally accurate calculate of the power use of one oven, friend would have to track the accumulation time that the heating element is functioning, not simply simply the cook time.

Overall, the slow cooker is going come be much more cost-efficient than utilizing an electrical stove-top or oven. The trade-off for utilizing the stove-top or cooktop is walk to it is in in the much shorter cook times compared to utilizing a slow-moving cooker.
