One of the major things that we mostly ignore while buying a water heater is the power rating of the heating element.
However, the power rating of the heating element plays a big role in deciding how much power the water heater will consume.
As a thumb rule, we know that a high-power rating heating element means more power consumption. It’s true. But when you check carefully, you might see different data based on different use cases.
So in this article, we will see the Difference Between 2KW And 3KW Geyser and find out which one is more energy efficient.
Why have we chosen 2 kW and 3 kW?
That’s because most water heaters are available with these power-rated heating elements.
Difference Between 2KW And 3KW Geyser
To understand the difference between 2KW and 3KW Geyser, we first need to understand what is meant by 2KW or 3KW
2KW or 2KWh means that the heating element will consume 2 units of electricity per hour. On the other hand, a 3 kW heating element will consume 3 units per hour. So, ideally, a 3 kW heating element is consuming more power per hour.
Please remember that a 2 KW heating element will generate less heat than a 3 KW element and thus take more time to heat water.
Now let’s take a real-life example. A 2 kW heating element takes about 20 minutes to heat 15 liters of water (The time may slightly vary based on the water temperature difference). So a 2 kW heating element can heat 45 liters of water in one hour.
On the other hand, a 3 kW heating element can heat 15 liters of water in just 15 minutes. So in one hour, it can heat 60 liters of water.
Now, if you look carefully, you will notice that a 3 KW geyser consumes more power, but you are getting more hot water too.
So, ultimately, a 3KW geyser is more economical if you have more people using hot water at a time. For small families, a 2 kW heating system makes more economic sense.
Conclusion: Difference Between 2 kW And 3 kW Geyser
If you have a small family of less than 4 members, then a 2KW geyser will be more economical, considering that not all four members will use the hot water at a time.
On the other hand, for big families, a 3KW geyser makes more sense as you will be getting more water by sacrificing a few units of electricity.
