In the average home, the water heater is the second most energy-consuming appliance, right behind the air conditioner. A water heater can use up to 18% of your total energy bill.

One of the best ways you can save money on your energy bill and keep your water heater working efficiently is to replace it with a new, more energy-efficient model.

But before you rush out to buy a new water heater, there are some things you should know about the different types of water heaters. These include the advantages and disadvantages of each option.

If you’ve been considering upgrading or replacing your water heater, whether your existing one is problematic or if you’d just like to know what systems are available to you, we’ve got you covered.

Read on to learn all about electric water heaters vs gas and decide which option is right for you.


When considering the cost of electric water heaters vs gas, there are several expenses to analyze. Electric water heaters are typically more affordable to purchase upfront. They also tend to be less expensive to install. This is because they don’t require venting.

However, the electricity used to power electric water heaters can be more costly than natural gas. Electric water heaters have shorter life spans than gas models. This can result in higher maintenance costs over the years.

Gas water heaters generally have a longer life expectancy. It needs less energy to operate. But they may be more expensive to install and may need extra venting costs.

Overall, the direct monetary costs must be weighed against the expected longevity and energy efficiency of each system in order to make an informed decision.

Maintenance Demands

Electric water heaters need less maintenance than their gas-powered counterparts. They do not need periodic maintenance to maintain their optimal efficiency and reliability. This is due to the lack of components. This includes the flue, pilot light, and thermostat, which must be serviced in gas heaters.

Electric water heaters also tend to have fewer service issues due to fewer moving parts. They also have fewer potential points of failure, such as pilot light burners or corroding parts, making them more reliable.

Electric water heaters also have a generally greater energy efficiency than gas. They have a higher EF rating since no energy is lost through venting.

Gas models tend to recover faster and provide a greater flow rate of hot water. Ultimately, when it comes to maintenance demands, electric water heaters have a definite edge over their gas counterparts.

Environmental Impacts

Electric water heaters have a significant advantage over gas as an energy source for heating water. Electric water heaters produce fewer greenhouse gas emissions. This is because electricity is generated from clean energy sources. Which includes solar, wind, and hydropower.

In comparison, burning natural gas produces large amounts of carbon dioxide, which is a major component of climate change. Electric-powered instant water heaters are much more efficient than gas water heaters. This means that the same amount of energy can be used to heat the water at a much lower cost.

Electric water heaters also tend to be better for the environment. They don’t release toxins into the surrounding air.

Gas-powered water heaters also release a variety of pollutants, including nitrous oxide, sulfur dioxide, and carbon monoxide. This makes them far less efficient than their electric counterparts.

Ultimately, electric water heaters are the clear environmental choice when it comes to climate change.

Lifespan Considerations

One important factor to consider when deciding between an electric water heater and a gas water heater is the lifespan and durability of each type.

Gas water heaters have the potential to last up to 10-15 years with proper maintenance. However, electric water heaters are only expected to last half as long with an average life span of 6-8 years.

Electric water heaters are cheaper to buy and maintain. But their durability and lifespan are significantly lower. This makes them a less cost-effective option in the long run. Gas water heaters, on the other hand, may cost more initially. But their long lifespans make them a more cost-effective option in the long run.

Ultimately, it is up to the consumer to decide which type of water heater will best meet their needs.

Installation Process

When comparing the installation process of electric versus gas water heaters, the complexity and cost of installation vary. Electric water heaters need less specialized knowledge, making installation simpler but more time-consuming.

Furthermore, they require both an electrical and water line connection. Gas water heaters require less time and fewer connections, but installation must be completed by a trained and licensed gas specialist. In terms of cost, electric water heater installation can be completed for cheaper as a DIY project or with a professional electrician.

However, gas water heater installation requires an experienced specialist, which often increases costs substantially. It is important to consider both the complexity and the cost of installation before choosing an electric or gas water heater.

Critical Safety Considerations

Safety considerations are critical when choosing between electric water heaters and gas water heaters.

The National Electric Code (NEC) states that electric water heaters must have a temperature relief valve and a solid dielectric union to prevent electric shock. They also require grounded three-wire power cords and grounding elements.

Gas water heaters require an approved venting system and access to a dedicated gas line or a propane tank ensuring that the necessary gas pressure is provided.

In addition, a temperature relief valve is also required and as with electric ones, must be serviced annually to avoid hazardous temperature spikes.

Finally, all water heaters should be inspected regularly by a licensed plumber or professional to ensure that any problems are detected and addressed promptly.

Learn the Difference Between Electric Water Heaters vs Gas Today

Electric water heaters are energy efficient and may be more cost-effective than gas heaters. However, gas heaters may require a lower upfront installation cost. The right choice depends on the homeowner’s preferences and budget.

It’s best to research both types of water heaters and make an informed decision on whether electric water heaters vs gas is right for your home. Contact a trusted service provider today and get the facts you need to make the best choice for your home.
