How much electricity does a geyser use per hour?

The amount of electricity used by a geyser per hour depends on several factors, including the geyser’s power rating (in kilowatts), the temperature of the water being heated, and the efficiency of the geyser. 


As an example, let’s say you have an electric geyser with a power rating of 3 kilowatts (kW). 


To calculate the electricity usage per hour, you can use the following formula:


Electricity Usage per Hour (in kWh) = Power Rating of the Geyser (in kW)


Using the example of a 3 kW geyser:


Electricity Usage per Hour = 3 kW


So, a 3 kW geyser would use 3 kilowatt-hours (kWh) of electricity per hour when operating at full power.


Keep in mind that this is a simplified calculation, and actual electricity usage may vary based on factors such as the geyser’s efficiency, the temperature setting, and how frequently hot water is used. Additionally, electric geysers typically consume more electricity than gas or solar-powered geysers due to the energy required to heat water.
