We are always concerned about power consumption when we use a water heater/geyser because it is one of the most power-hungry appliances.
We always make the mistake of not checking the Power Consumption Of Geyser before buying it. Although manufacturers mentioned the rated power data, there was no easy way to calculate the power consumption of the water heater.
To solve this problem, we are presenting a calculator that will calculate the power consumption of geysers from the rated power data in this article.
Power Consumption Of Geyser
Disclaimer: The calculator was developed with different assumptions, which might benefit most consumers. However, individual usage may vary, and many factors could contribute to the Geyser Power Consumption. This calculator is meant to give you a rough idea about how much electricity your geyser may consume based on your inputs and considering the best-case scenario.
The power consumption of a geyser depends on many factors, including the capacity of the geyser, the type of geyser ( Instant / Storage), the standing loss, and numerous other factors.
However, every manufacturer must provide data on the power ratings of all geysers. We can use that power data to calculate the power consumption of geysers easily.
The rated power data will be available on the BEE Star rating sticker on all geysers, as it’s a legal requirement.
Geyser Power Consumption Calculator Inputs
The following inputs are required from your end to calculate the geyser Power Consumption.
- Rater Power Of The Geyser [This data will be available on the product specification sheet or the BEE Star Rating sticker.]
- Hours Of Operation Per Day [Enter the hours you want to run the geyser daily. If you are not using the geyser daily, enter the average number of hours daily.
- Electricity Tariff Per Unit [You will get that information from your electricity board or your last electricity bill]
Geyser Power Consumption Calculator Outputs
You will get the following values once you enter the correct input values.
- Monthly Units Consumed By the Geyser (kWh)
- Yearly Units Consumed By the Geyser (kWh)
- Monthly Electricity Bill
- Yearly Electricity Bill
Water Heater Power Consumption Calculator
Geyser Power Consumption Calculator Assumptions
We did not consider the standing loss factor while calculating the power consumption data. Please note that the power consumption data may also vary slightly based on the temperature of the desired water.
For example, if the input water temperature is 20°C and you want your geyser to deliver water at 50°C, it may consume less power than if the input water temperature is 5°C.
So the main thing here is that the more significant the difference in temperature, the greater the power consumption will be. Manufacturers share the rated power data based on some ideal case scenario, which may not always be true in the real world.
5 Tips To Reduce Geyser Power Consumption
Here are some tips to reduce the geyser’s power consumption.
Use The Correct Capacity Geyser
It is always a good idea to use a correct capacity geyser. If you buy a high-capacity geyser but do not use that much water, it wastes power.
Please remember that a higher capacity geyser means a higher amount of water and a higher amount of power consumption.
Prefer To Use Storage Geyser
Instant geysers are cheap, so many people buy them. On the other hand, instant heaters consume more power than storage heaters of the same capacity.
The instant heater has no storage tank, so it can not hold hot water. All it does is heat the water instantly while it passes through the geyser. That consumes a lot more power than storage heaters.
Set A Reasonable Thermostat Temperature
All geysers come with a thermostat that cuts off when the desired temperature is reached. Set your desired temperature low so the geyser does not have to work much to heat the water.
It is preferable to keep the temperature between 50°C and 60°C, as a human body can tolerate this. Keeping a higher temperature is just a waste of power unless you want to use that for washing clothes or dishes.
Turn Off The Power When Not In Use
Some people believe the thermostat will turn off the power when not used. But that is not true.
The thermostat does nothing apart from cutting off the power when the desired temperature is reached.
When the temperature goes down, the thermostat will start working again, and this will go on again and again, which will consume a lot of power.
That is why you should turn off the power when not in use or use a timer in the geyser to turn off the power after a set duration.
Use A 5-Star Rated Geyser
5-star-rated geysers consume less power than 3-star-rated geysers, although the difference is not that much. If your usage is higher, using a 5-star-rated geyser is better.
Please remember that 5-star rated geysers are a little costly, but these geysers come with many advanced features to save power.
Conclusion: Power Consumption Of Geyser
During winter, geysers can contribute around 30-50% of your power bill, like an AC does during summer. So, it is always wise to check and control the energy consumption of water heaters.
The first step is to buy an energy-efficient geyser, and for that, you can use our calculator to find out how much electricity the geyser may consume. Based on that, you can make an informed purchase decision.
