Is the electricity bill of electric kettle a great deal? Explain with the electric pot!

How to calculate electricity bill

Before entering the main subject, I will briefly explain from the method of calculating the electricity bill for home appliances.If you want to know the main subject, you can skip this block.

In the first place, the electricity bill is required in the following formula.

Electricity fee (yen) = W (wattage) ÷ 1000 x h (used time) x 1kw electricity bill

The following is a explanation of each value.

If it is troublesome to calculate in the above formula, it is also recommended to use a calculation tool, such as an electric calculation tool site.

Calculate the electricity bill for electric kettle!

First, check the power consumption (W) of the electric kettle.This time, as an example, we will calculate based on the classic T-FAL model "Apresia Plus".According to the T-Fal website, the rated power consumption of the kettle is "1250W", so use this number.

Next is time (H).According to the HP, if it is a cup of water (140ml), it can be boiled in about 53 seconds.Since 53 seconds is about 0.88 minutes, the use time to put in the formula is "0.88/60 (H)".

When these numbers are assigned to the above formula, the formula is as follows.

電気代(円)＝1250W÷1000×(0.88/60)h×27円/kW＝0.495円

つまり、電気ケトルで1杯程度のお湯を沸かすのに必要な電気代は約0.495円ということがわかります。公式がわかると意外と簡単に電気代を出すことができますね。

From the above, if two cups of water (280 ml) are boiled, it is assumed that the number of electricity of 0.495 yen is simply doubled and the electricity bill of about 1 yen is assumed ( *).If you boil two cups of water every day four times for a month, it will be about 1 yen x 4 (times) x 30 (Sun) = 120 yen.

What is the electricity bill for an electric pot?

Next, let's look at the electricity bill for electric pots.

In the first place, the difference between electric pots and electric kettle lies in "capacity" and "heat retention function".In an electric pot, you can keep the water warm even after boiling.Therefore, electric pots tend to increase electricity.

According to the T-Fal website, when 1L of water is boiled, the kettle is about 2.6 yen and the pot is about 7.6 yen ( * 1).Depending on the use, it seems that electric kettle is more advantageous if you focus on the "electricity bill" instead of simply "capacity" or "heat retention function".

What is the electricity and gas bills of the kettle?

Next is the kettle.According to the T-FAL website, when 1L of water is boiled, when a kettle is heated with propane gas, it costs about 3.36 yen ( * 2).As mentioned earlier, the electricity rate for boiling 1L water in a kettle is about 2.6 yen, so there is an electric kettle in terms of saving.

However, when warming the kettle with an IH stove or city gas, the difference between electricity and gas costs is small.When comparing with the kettle, the examination seems to differ depending on the conditions such as city gas, propane gas, or IH.

How to save electricity bills for electric kettle?

By the way, we will introduce "how to save electricity with electric kettle" below.The effects of each one are a few, but if dust is piled up, it will be a mountain.Let's accumulate a little ingenuity and save electricity bills!

Power saving method 1. Buy a kettle that suits you

First, buy an electric kettle with a capacity that suits your life.

There are various variations for electric kettle, such as those for families and those for one person.The higher the capacity, the more time it takes to warm it, so the power consumption tends to be high.In addition, some have a heat retention function, and the power consumption differs depending on the manufacturer.

Of course, the difference between capacity and functions can be said to be the same in electric pots.Therefore, it is a standard function to save electricity with a standard function than buying a size or function that is more than necessary.

However, even if you buy a small one to save, you will fall down if you use it many times because of lack of hot water.Think about what suits you and buy it.

Power saving method 2. Boil as much as you use

Many electric kettle does not have a heat retention function.Therefore, if you boil it more and leave it, it will cool down naturally.So, when boiling water, be aware of "adding water as much as you use".In addition, even if the kettle does not have a heat retention function, you can keep hot water with a warm -stored container such as a thermos.

Power saving method 3. Clean the kettle firmly

If you do not clean the electric kettle, the scales of white capikapi will be on the bottom.If you have scale, it will be difficult to convey the heat, so it takes time to boil the water and it costs extra electricity.Citric acid and baking soda can easily fall off, so keep them clean.

Power saving method 4. Remove the outlet when not in use

Needless to say, home appliances have waiting power.A standby power is a power that consumes even when the home appliances fled by the outlet are turned off.In particular, water heaters, air conditioners and TVs tend to be high.

By removing the outlet, the electricity bill for the waiting power will not be charged, so if you do not use it, you can expect a little power saving by pulling out the outlet.However, some products do not have standby power, so it is a good idea to check in the instructions at the time of purchase.

Power saving method 5. Use kettle hot water for cooking

This is not a power saving method of the kettle itself, but by transferring the boiled water in a kettle to a pot, the use time of the stove can be reduced.Because it can be saved in time, it is a very useful ingenuity when boiling something or when a bath.

Especially for families that use propane gas, it will contribute to the saving of gas.

***

Above, we have introduced the electricity bill for electric kettle.

Even if you were not very conscious, you would have been able to deepen your understanding of how to calculate and think about electricity bills.

Electric kettle is a convenient item that can be expected to save electricity bills and to have a time -saving effect on cooking.By all means, please look for something that suits you and use it.
