– How Much Electricity Does an Induction Cooktop Use Per Month?
In reality, if your household uses a gas stove to cook food in a pot, you first have to heat the air under the pot before the pot itself is heated. This means only about 40% of the heat is directly transferred to the pot, while 60% is lost to the environment.
On the other hand, induction cooktops work by directly heating the pot, achieving up to 90% efficiency. Only about 10% of the heat is lost to the surroundings. This superior heating method of directly heating the food in the pot is what makes induction cooktops so efficient.
When using an induction cooktop, you can safely touch the area outside the cooking zone without burning yourself.
The power of an induction cooktop indicates how much electricity it consumes. To calculate the monthly electricity consumption of an induction cooktop, you first need to know its power consumption, which can be found on the label, packaging, or in the technical specifications of the product.
Additionally, you need to estimate the actual cooking time in a month.
For example, according to our estimates:
Let’s say you buy a double induction cooktop with a power of 2000W for each cooking zone. On average, it takes 30 minutes to cook a meal.
This means: 0.5 x 4000W = 2KW (electricity)
If you cook two meals a day with this electricity consumption, it will cost: 2 x 1.5 x 2 meals = 6,000 VND/day.
For a month (30 days) x 6,000 VND = 180,000 VND (for a standard induction cooktop).
What about a gas stove? Usually, a gas cylinder costs around 300,000 VND, and a family of five cooking two meals a day will use about 1.5 cylinders per month, costing approximately 200,000 VND/month. Moreover, you also face the daily risk of fire and explosions due to the abundance of fake and low-quality gas cylinders and stoves available in the market, with no regulatory control.
– Should You Unplug the Induction Cooktop After Cooking?
If you’re unsure whether to unplug your induction cooktop after cooking, read the following essential information before taking any action.
Unplugging the induction cooktop can reduce its lifespan and pose a danger to the motherboard and internal components.
Whether or not you should unplug the induction cooktop depends on the situation. If you’re just cooking a regular meal and unplug it afterward to save electricity, this could be a mistake that leads to faster deterioration of the cooktop.
Induction cooktops have a high cooking power, quickly heating the cooking zone to high temperatures. This causes the fan inside the cooktop to work continuously to cool all the components and parts under the cooktop.
If you suddenly unplug the cooktop, the fan will stop working, and the components will not be cooled.
In the case of using an induction cooktop with an infrared zone, the infrared zone takes longer to cool down, which can lead to cracked glass and burns if touched.
If you repeatedly do this, you will soon have to replace the cooktop as the components weaken, the circuit board becomes unstable, and other parts become almost “paralyzed.”
In this case, it’s best not to unplug the cooktop. Instead, turn it off and let the fan cool the internal components for about 30 seconds to a minute until the cooktop is cooled down, and then unplug it. You don’t have to worry about excessive energy consumption as the fan uses very little electricity.
Wait until the cooktop is cooled and the fan has stopped working before unplugging it to ensure safety and maintain your induction cooktop.
Using Induction and Infrared Cooktops Correctly
Don’t Block the Ventilation Fan
Placing bottles of spices or other kitchen items in front of the ventilation fan will cause the cooktop to deteriorate faster as it won’t be able to dissipate heat effectively.
Clean the Fan Vent with a Brush and Cloth
Over time, use a brush to clean the fan vent to prevent dust from clogging the ventilation system and causing the cooktop to function poorly.
