Can A Bad Water Heater Raise Electric Bill And Gas Bill?

A malfunctioning water heater can potentially raise both electric and gas bills. If the water heater is electric, a malfunction can cause it to use more energy than it should, leading to higher electric bills.

If the water heater is powered by natural gas, a malfunction can cause it to use more gas than it should, leading to higher gas bills.

Additionally, if the water heater is not properly insulated, it can also result in higher heating bills.

It’s best to have regular maintenance and to address any issues as soon as they arise to avoid additional costs.

Always remember that a broken water heater can be costly. If a water heater’s bottom is too sedimented, it will require more energy to heat water adequately.

In many cases, the water still does not get heated properly despite the increase in energy. In other words, you pay more money for subpar water temperatures when your water heater breaks.

Is A Water Heater Going To Increase Your Utility Bill?

Is A Water Heater Going To Increase Your Utility Bill

Many factors can affect the monthly cost of your utility bill, including your water heater. When you consider what your water heater consumes and contains, you’ll see how your water heater’s bill can go up if it’s not working properly.

Your water heater generates heat to warm the water in your home that needs hot water to function. Depending on the commodity, energy, and water you use, this will affect your utility bill.

Is A Water Heater Responsible For High Gas Bills?

As much as 15% of your total natural gas bill can go towards paying for your water heater, which uses gas or natural gas.

The inefficiencies of old gas water heaters can negatively affect their effectiveness and increase fuel consumption.

Similarly to electric water heaters, lime and mineral buildup in gas water heaters need to be removed periodically by draining them.

Additionally, old, and perished gas pipes can cause gas leaks, which can be dangerous and cause your gas bill to rise.

Make sure your gas water heater is serviced regularly, and if it is reaching the end of its useful life, replace it with a newer model, which is more efficient and will lower your gas bill.

How Does A Bad Water Heater Affect My Electric Bill?

How Does A Bad Water Heater Affect My Electric Bill

When you spend a lot of time in your home, you expect certain things to remain consistent. It’s funny how you can hear the creak of the steps when you step on them after midnight snacking.

It is easy to control the temperature of the water in the shower by turning the nozzles. The electric bill should look like this every month at the end of the month.

As a result, if you noticed spikes in your electricity bill when you weren’t expecting them, you should identify the cause as soon as possible.

It can be difficult to pinpoint which component of your house is causing the high electric bill if you don’t know where to look.

Those who don’t consider a broken water heater an option may not even consider it.

Hence, what does a faulty water heater do with your energy bills rocketing? Do you want to reduce energy bills with a routine water heater repair service?

1. Age

It is common for water heaters to last for between 10 and 15 years. Usually, when the water heater unit is older than this, its efficiency begins to decline.

In this case, you will certainly see an increase in your energy bill as the heater takes longer to warm up the water. It is necessary to replace the water heater to fix the problem.

2. How Long Does It Take To Warm Up Your Water?

How Long Does It Take To Warm Up Your Water

Depending on your water heater’s speed at heating water determines how efficient it is.

A slow heater can lead to a skyrocketing electricity bill since it takes so long to heat up your water.

If faulty parts and your water heater is old, it may significantly impact how well it warms the water.

3. Malfunctioning Parts

An adequate maintenance plan can help your water heater last for many years without having to be replaced. Nevertheless, some parts can start failing during that time.

As your system begins to malfunction, you may start seeing an increase in your electricity bills.

Your system might be experiencing problems because of an overflow pipe or a broken pressure relief valve. You can save money on your next energy bill by contacting a trained professional.

4. Are You Using The Correct Sized Unit?

Are You Using The Correct Sized Unit

The type of water heater you use for your home matters, whether it is an electric or tankless one.

If you don’t have enough space or capacity for your home’s ongoing water needs, your water heater will work overtime to meet them.

The best option is to upgrade to a water heater with the capacity you need instead of using a lower-capacity one.

5. What Is Your Thermostat Set To?

You may not be aware of the importance of your water heater’s built-in thermostat to its overall performance and efficiency.

Having that thermostat set too high causes your heater to take longer to reach that target temperature, which uses more energy.

You can drastically reduce your electricity costs by setting your thermostat to a more reasonable temperature.

6. What’s The Energy Efficiency Rating?

What's The Energy Efficiency Rating

There is no such thing as an equal water heater. Depending on the company, some units prioritize energy efficiency more than others, whereas others may be more concerned with providing cheaper, less reliable units.

You should keep an eye out for the energy efficiency rating on a new water heater manufactured by a reputable manufacturer.

7. Hard Water

It is possible for minerals and sediment collected in hard water to settle at the bottom of your water heater and coat the heating element, which reduces its effectiveness. An increase in energy costs will result from this.

If a quarter inch or more of lime and mineral deposits build up on the bottom of your water heater, the efficiency can be lowered by as much as 20%. Cleaning out the sediment is as easy as flushing your water heater once a year.

Is It Possible To Use More Water With A Water Heater?

Besides your electricity bill, your water bill is also included on the bill. Your water heater stores a large quantity of water at any given time.

The increased costs might be related to your water and energy bills when you have a water heater that is not performing optimally.


Water heaters must have inlet and outlet connections for the necessary flow of water. As an appliance that isn’t seen daily, faulty fixtures, connections, and pipes can go undetected at the water heater.

Leaks can become significant and increase the amount you have to pay for energy and water. If you see more water and energy usage, you may want to inspect your water heater to prevent further expense increases.

Long pipes

It may take some time before warm water is dispensed if the distance between the water heater and the faucet is extensive.

This will not only use more water and raise the water bill, but it will also result in more water being taken from the water heater, which will use more energy to heat the cold water.

To solve this problem, install a small water heater near the outlet. The result is a reduction in both the amount of water and energy consumed.

Final Words

It is essential to inspect the water heater unit immediately if you notice any sudden or gradual rise in your utility bills.

In a household where water heaters are significant energy consumers, the costs can quickly rise if something goes wrong with them or if they aren’t set correctly.

Service and inspections of your water heater can catch problems early and replacing a faulty unit can reduce your long-term costs.
