Having a washing machine is very big convenience for all kinds of households, be it small or large. It saves your energy and also a lot of time. Instead of going to the nearest stream or the public laundry, you can wash your clothes easily just at your home using a washing machine.
But are you aware of the energy it consumes? Well, if you aren’t, this article can help you. Here, you can learn to calculate the power that a washing machine consumes. If you’re interested in using the washing machine efficiently, read along.
How Does a Washing Machine Work?
Although every washing machine works differently, there’s a standard procedure. There’s a big drum inside the washing machine where you place the clothes. A washing machine agitates the clothes with soapy suds & water to clean them. Once the cycle is complete, it spins and drains the water out of the machine.
Majorly there are three types of washing machines: –
- Top load agitator
- Top load impeller
- Front Load agitator
How Can you Calculate the Power Consumed by your Washing Machine?
The power consumed by a washing machine depends on two factors. First is the electric motor of the machine which spins the drum. And the second one is the heating component, which is used to heat the water to be used for cleaning.
The heating equipment of the machine consumes about seventy percent of the power, and the motor pump consumes thirty percent of the remaining power.
First of all, to calculate the power consumption, we need to look at the wattage or the machine’s total rated power. It is generally written on a label at the backside of the machine, on its manual, or you can also find it online by typing the machine’s brand and model.
A washing machine of 7kg will be using a power of 2000-2500 watts if used at full capability using the hot water component. But if the water isn’t heated and only the electric motor pump is used, then the power consumption would nearly be 500watts.
Let us take an example of a 6 Kg washing machine of a brand “Y” that uses 2000watts of energy when used in a full load. That is using the hot water to get the clothes cleaned. The machine has a regular power rating of 500watts without the heating equipment.
Power Consumption (kWh) = Power rated(in kW) * total operational hours
We can calculate the power used by the machine based on two cases.
Case 1: The washing machine uses the heating equipment to heat the water and uses 2000 watts (2kW) of energy as per the company’s rating. If used for one hour, it’ll consume 2kW*1hour =2kWh or two energy units.
Case 2: The washing machine uses normal water to wash the clothes. It uses 500 watts (0.6 kW) of energy. If used for one hour, it’ll consume 0.6kWh*1= 0.6 kWh (0.6Units) of energy.
So, now you can understand that the washing machine uses 0.6units of energy without using a hot water mix and consumes 2kWh of energy when the hot component is used.
How to use a Washing Machine Efficiently to Save Electricity?
Buying an efficient device is not enough to save electricity. The way you use and operate it also makes a big impact. The efficiency will largely depend on how and how much the machine is being used regularly. Please refer to some good tips that can help you in saving electricity: –
Size of the washing machine – Always chose the washing machine according to your requirement. Buy a smaller size of a machine if you are a family of four members. And if you have more members in your family, you can go for a bigger one. This is because the bigger the machine size, the more will be the electricity consumed.
Use the right amount & type of detergent- A good quality detergent will wash the clothes in fewer cycles, whereas you might need multiple cycles to get the clothes cleaned using the wrong or a bad quality detergent.
Similarly, if you do not put an ample amount of the detergent, then again, it might need multiple cycles to clean the clothes.
Use a fast spinner instead of a dryer to dry the clothes – Instead of using a dryer that uses heat to dry your clothes, use the fast speed spinner to dry them. This will help in saving electricity. This process is called mechanical drying and is better than thermal drying.
Front-load or top-load – The top loaders have shorter cycles but use large amounts of water. At the same time, front loaders have longer cycle but make less use of water. The heating can increase power consumption to a great extent.
If hot water is used for washing the clothes, top loaders will consume excessive electricity, and if front loaders use cold water, it would have longer wash cycles. It all depends on the way you use your washing machine.
Load the washing machine optimally – Always use or try to use the machine in a full load. This is because the same amount of electricity is used even if the machine isn’t fully loaded.
Reduce the heating – Try not to use the heating element while washing clothes. Heating can increase electricity consumption and cost up to ninety percent. Using heat is not only expensive but also can damage your clothes’ fabric too if used excessively.
Basic information like how much energy the washing machine consumes is quite helpful. Not only it tells you how much you’re going to pay, but it also tells you about the machine’s efficiency as well. If you find that your washing machine is not efficient, you can follow the above points and save energy.
Or you can buy a new, more efficient washing machine. If you liked the above insights, please share them with others. We’re going to post more similar content soon. So, keep coming back for more.
