Hot water is required for bathing in winter, and for this both induction cooktop and electric geyser options are available. But there is a difference in energy consumption and expenditure between the two. Let us understand which of these options is less expensive.
electric geyser
Geyser requires less electricity to heat water because it is specifically designed to heat water. It can heat more amount of water in less time, thereby reducing electricity consumption.
Electric geysers usually range from 1.5 to 3 kilowatts (kW). A normal 15-20 liter geyser takes 10-20 minutes to heat water. If the geyser is of 2 kW and it is operated for 15 minutes (0.25 hours), the power consumption will be 0.5 units.
induction cooktop
Induction cooktops also range from about 1.5 to 2 kilowatts, but are not specifically designed to heat water. Using an induction cooktop to heat water consumes more time and energy. It can be used to heat water in small vessels, but for larger vessels or more water, it takes more time.
To heat water on induction, you have to boil it again and again and be careful. Additionally, this method is not practical for regular use, especially if heating water in large vessels is required on a daily basis.
Which option is better?
Electric geysers are more efficient and energy-sensitive for heating water. It also costs less because it can heat a large amount of water in a short time. Using geyser is also simple and convenient. You can leave it set and in a few minutes you have hot water ready. Therefore, electric geysers are a less expensive and more convenient option for bathing in winter.
