Water Geysers- Use It Right To Lower Electricity Bill

Updated by

Gone are the days when people had to manually heat the water and carry it to the bathroom only to realize that it has gone cold again. Water heaters or Geysers are one of the best inventions that mankind has come up with to make our life easier.

These technologies are not only convenient for heating water but also a very efficient resort to save money on the electricity bill. But, do you know how actually you can use this device and lower your electric bill drastically? Well, let’s find out everything in this article.

But before we go any further we want you to learn about a very vital component of this device that will later come in handy. So, without much further ado, let’s begin.

What is a Thermostat?

A water heater could turn into an expensive investment due to the ignorance of important components or simply by not taking proper care of the units. That said, almost every water heater comes with a thermostat, and using it in the right way can save your money on electricity bills. But what is a thermostat?

A thermostat is nothing but a device that controls the temperature in a water heater. Basically, the function of a thermostat in a water heater is to keep the water temperature at the desired level, and when this level is achieved the thermostat automatically shut down the power supply.

This device helps to check the water temperature and switch the heater back ON if the temperature decreases. A thermostat comes with different customizable settings to set the temperature accordingly. We shall discuss this later in this article.

How do I find a Thermostat in a water heater?

Thermostats in a water heater are attached to the side of the tank. Most models come with plastic or metal covers that hide the thermostat and other components. So, to do the adjustments, you will have to remove the cover first.

Talking about adjustments, there are two types of thermostats you will find in different models. One – thermostats that are adjustable and second – thermostats in which settings are default and are not adjustable.

Customizable thermostats come with knobs that rotate and allow you to change the temperature setting. However, thermostats that are non-customizable have 55 – 60 Degree Celsius as their default settings and come with a green and red light to notify whether water is heating or not.

What is the Ideal Temperature for a Water Heater?

According to an ‘energy-saving’ website handled by the government, a good temperature in a water heater is around 50 degree Celsius or 120 degrees Fahrenheit for almost every household purposes.

In the market, water heaters come with a range of 40 to 75 degrees Celsius, this means the highest temperature that could be set in your thermostat will be 75 degrees Celsius or 167 degrees Fahrenheit.

Ideally, the best advice is to keep the temperature in the mid-range or set the thermostat settings in the center. This will not only heat your water but will also save your electricity bill.

Keep in mind that the electricity consumed by your water heater will depend on the temperature that you set on the heater or thermostat. This means the higher the temperature of your water heater, the higher will be the energy consumed hence high electricity bills.

Does a Thermostat in a Water Heater Switch off When the Water is heated?

In short, Yes! A thermostat is designed in such a way that when the water reaches the desired temperature it automatically switches off the heater. That being said, it is extremely crucial that this technology should not be taken for granted.

What we mean by this is that many people have a habit to leave the switch ON and completely rely on the thermostat to do its magic. Sure, the thermostat will switch off the heater once the desired temperature is reached but, it will turn the heater ON once again if the temperature decrease.

This will result in energy wastage and you will without a doubt experience high electricity bills.

Things that save electricity in water heaters:

Below are some of the most important things that you can follow to lower your electricity bills in water heaters.

1: Correct the Thermostat Settings

A thermostat is a device that helps to keep the temperature at the desired level and cut off the power supply once the water is heated. It comes in two different variants – one that allows you to change the settings and the other comes with a default setting.

An adjustable thermostat ranges between 40 and 75 degrees Celsius. This means if the thermostat settings are set to 75, the water will get extremely hot and will require cold water before use. This is a clear indication that the heating is done in excess and more energy is consumed.

To save this from happening, maintain a mid-range temperature like 50 degrees Celsius for the best results.

2: Lower the Temperature of the Water Heater

If you want to see fewer digits in your electricity bill it is advisable to keep the temperature of the water heater low. Just by lowering the temperature of your water heater, you could reduce the energy consumption by up to 5%.

3. Do not keep the Water heater switched ON for longer

People completely rely on the thermostat for switching off the power supply once the water is heated but actually, this is a poor habit and should be avoided at all costs.

When the water heater is switched ON for a longer duration it uses excessive electric energy and shoots up the electricity bill. To avoid this, you can do two things and both of them goes hand in hand:

  • Lower the water heater temperature
  • Set a timer

4. Choose the right sized Water Heater

You don’t want an oversized water heater, just choose a model according to your daily consumption and the size of your family.

5. Choose Star Rated Heaters 

Water heaters are rated by stars based on how low they consume electricity for heating water. This means a ‘5 Star’ rated water heater will be more efficient in comparison to lower star rated heaters.

6. Prefer short showers over hot water baths

If you have a habit of filling the entire bucket or bathtub with water and bathe you might want to switch to short warm showers for saving energy. Short showers are better than bucket baths and could be more refreshing too!

7. Turn off the Tap When Not in Use 

We were lectured on this matter in our childhood, but are we strictly following this learning? When you shampoo your hair, apply soap on your body or shave, just turn off the tap to save water wastage and see fewer digits in your bill.

8. Fix costly leaks 

Leaks are very common in the water supply but, ignoring them could cost you a lot of money. According to a survey, one drip of water in a steady leakage means wastage of approximately 8.70 gallons of water per day. So, if you have even a minor leakage in your unit, contact a qualified technician ASAP.

9. Insulation Helps 

Insulation here means saving the heated water in special valves or storage tanks so that it could be kept warm for a few hours. Insulating the water once will not require the heater to reheat the same water. This means lesser usage of water heater, less energy consumption, and hence lower electricity bill.

10. Low Flow Fixtures and Leakages

If your property has low flow fixtures, we suggest to keep it that way and don’t replace them. Low flow fixtures reduce water consumption by twenty percent and are a great way of saving water.

They also reduce the amount of energy consumed in heating. How? A higher flow rate means more energy is required for heating the water whereas, low flow fixtures that have a lower flow rate require less energy for heating.

If lowering the electricity bill is your priority, then leakage on low flow fixtures could affect your goals. Make sure there is no malfunction in the connection and water flows properly. You don’t want to just save money but, the natural resource too!

11. Use cold water for Laundry

Using hot water for laundry will not only waste electricity but, will also damage the fabric. It is advisable to use cold water for laundry unless you are fighting tough stains.

12. Consider purchasing a new water heater 

This is a very important thing that you should keep in mind if you are serious about lowering the electric bill. If your water heater has seen days let’s say more than 10 years, it is time to replace it with a new one.

A good reason to switch to a new water heater is that you will have the latest upgrades in your arsenal and chances are quite high that you will be able to save more money on your bills. Here are some signs that you need an upgrade in your water heater:

  • Old unit
  • Water does not heat as per the set temperature.
  • Your unit is making noises.
  • Unrepairable leakages
  • Rusty water


There you go, twelve things that could majorly lower your electricity bills in no time. A water heater is an essential household appliance and could consume a lot of electricity if the above-mentioned points are missed.

Sure, there might be other things that could save you more energy, we brought you some of the easiest and underrated ways to lower your electric bill. Hope you learned something valuable from this article. Good luck!
