In today's blog post, we will discuess how much electricity an electric geyser consumes and how you can reduce your electricity expenses.

How Does An Electric Geyser Affect Your Electricity Bill?

There is a great need for hot water in winters, but when our electricity bill comes, It gives a bit of a shock, right?. Especially if we use electric geyser, then this question must be coming in your mind that how much electricity does this geyser consume?

A water heater is one of the most common household appliances that are used to heats water in your home or office.

The average wattage of a water heater can depending on factors such as the type of heater, its size, and efficiency, a normal domestic water heater uses consume anywhere from 3,000 to 5,000 watts ,the average energy consumption of a residential water heater is 4000 Watts.

  • Electric water heaters: Residential electric water heaters models uses bewteen 3,000 watts to 5,000 watts and larger or commercial electric water heaters consume more energy depending on size on heater.
  • Gas water heaters: Gas water heaters consume usually much lower power than electric geyser. A Gas water heaters can consume bewteen 400 to around 1,000 watts.
  • Tankless water heaters: The wattage of tankless water heaters depending on the model and size, but they generally have higher wattages, They can user power from 10,000 watts to 30,000 watts or more.
But this is just an estimate, and your actual usage may be more or less than this, depending on the capacity of the electric geyser, your usage pattern and technology. 

How much electricity does an electric geyser consume? 

The electricityof consumption that an electric geyser depends on many things, such as:

  • Capacity of the Geyser: Big geysers consume more electricity
  • Water Heating Temperature: The hotter the water you need , the more electricity will be consumed. 
  • Time of Running the Geyser : The longer you run the geyser , the more electricity it will consume.

How to reduce electricity consumption?

You can reduce your electricity expenses in some easy ways:

  • Use a smaller geyser : Choose a geyser based on your needs.
  • Do not heat water too hot : Lukewarm water  is enough, not boiling water.
  • Heat Water in Buckets for Bathing: Instead of filling the entire tub. Use hot water as per your need.


water heater Power consumption

The average energy consumption of a water heater:

Type of Water Heater Average Annual Energy Consumption
Electric (Small) 3,500 kWh
Electric (Medium) 5,000 kWh
Electric (Large) 6,500 kWh
Gas (Small) 40,000 BTU/h
Gas (Medium) 50,000 BTU/h
Gas (Large) 60,000 BTU/h
Solar Variable (depends on sunlight)
Tankless Variable (depends on water flow and model)
Using the below tools you can easily calculate water heater cost.But this is just an estimate, and your actual usage may be more or less than this depending on the wattge, capacity and technology of your electric geyser.

How much electricity does a water heater use?

Let assume that your water heater operates 1 hour a day, Average power consumption of the water heater between 400 to 1300 watts.

Let’s take an example and say your model uses 600 watts, you can find The wattage label that displays the power consumption of the electric water heater, Look like this or check device manual.

4000 watts X 1 hours = 4000 watt-hours per day

How many kilowatts does a water heater use?

4000 watt-hours per day / 1000 = 4 kWh per day

How much does it cost to run a water heater every day

4 kWh per month x 0.10 per kWh = $ .4 per day

How much does it cost to run a water heater?

4 kWh per day X 30 days = 120 kWh per month
120 kWh per month x 0.10 per kWh = $ 12 per month

@assuming per cost 10 cents

Important things keep in mind while installing a water heater

If you take care of some things while maintaining the geyser, you will also be able to save electricity.Here we are telling you that if you are going to buy geyser, then keep these things in mind.

A good geyser or water heater heats up water in just a few minutes and it is quite safe as well as it consumes less power.

1- The new tankless water geysers consume less electricity, while the traditional water heater stores water, which consumes more electricity.
By the way, Tankless geysers are slightly more expensive than traditional geysers. You can choose according to your convenience.

2- Make sure that there is a small gap left between the wall and the geyser. Otherwise, you will face problems while servicing or repairing the geyser.

3- Many people installed geysers at high altitude, this should not be done. According to experts, the geyser should be install at least 1.8 meters above the ground or a maximum of six feet. During servicing or repair, you will face problems.

4- Also, make sure that the geyser is connected to the MCB (miniature circuit breaker) so that it automatically turns off when the voltage is high. So that the possibility of short circuits from the geyser also reduces.

How to take care of geysers?

1- Do not keep the geyser switch on for long. For example, if you are going for a bath, then run a geyser five minutes before that.

2- The geyser can be maintain even by keeping its temperature low.
Keeping a low temperature means that the geyser will have less burden and will last longer while running at higher temperatures will put more emphasis on it.

3- Before winter, check the anode rod inside the geyser tank. According to experts, this work should be done at an interval of every three years.

4- Do the servicing of the geyser once a year.

5- Take care of geysers size

First of all, before buying geysers, take care of its size.Always choose the size of the geyser according to your bathrooms.

Always buy geyser which automatically closes after the heating of the water, because people forget to turn it off, which will increase the electricity bill. Automatic geysers also save your energy.

Limited resources like water need to be used carefully. Also, we should pay attention to the power savings, because their production is at the expense of the environment.

Of course, the water heater is a great necessity to keep life simple in the winter, But during this time we should be avoided the wastage of the resources.

6- If the water in your tank has become hot, then switch off its switch. Bathe in water instead of the shower, because it saves water.

Water heater wattage makes the water heat fast or slow. If we buy 4.5 kW of the water heater, then he will heat the water faster than a 2 kW capacity water heater also stop wastage of extra hot water.

There is only one negative side that, it increases the power load of the house, which increases the power load of your home, which will increase your connected load and ultimately increase the bill.

Everyone needs hot water to take a bath in cold weather, for this we need Good quality geyser.However, we must remain alert to stop the wastage of water and energy in their use.

Bathing with cold water is good for skin. so please prefer normal water for the bathing.

Ideal temperature for bathing

The normal temperature of the human body is 37 ° C, and any temperature above it feels hot and produce irritation.
The temperature of 46 degree Celsius is too hot for the human body, although it is less dangerous than the 60 degree Celsius.

if your water heater heats the water up to 60 degrees Celsius, but you have to mix extra cold water to make it bearable.

A 100-liter water heater’s standings are more than 1 unit/day, the standing loops of a 70-liter water heater are 0.9 units/day.

However, due to decreasing size, standings losses also fall in the same proportion.If you leave the water heater open throughout the day, you definitely damage the full standings.

To minimize the standings losses, we should only heat the water in the appropriate amount and after the use, the water heater should be a turn-off.so that we can save the waste of electricity.

Talking about money, tankless geysers are more expensive than tank geysers. When buying, pay attention to your budget and your family size as well. You can buy the geyser that suits you according to your needs.
