Gas Water Heater or Electric – Which is Better?

When considering a water heater upgrade, the type of energy available in your home—whether gas or electric—often drives the decision. However, for those aiming to maximize efficiency and reduce energy costs, exploring both options can be a wise move. If your current water heater is powered by gas or electricity, you may wonder if switching to the other option could offer better savings or performance. Let’s explore the differences between gas and electric water heaters to help you decide.

Which Water Heater Is Better for You: Gas or Electric?

The ideal system for your home depends on the type of water heater you choose—either a traditional storage tank model or a modern tankless system. Both gas and electric models have distinct advantages and considerations, so let’s break down which fuel source may be best for your household.

Storage Tank Water Heaters

Storage tank water heaters are the most common style and work by storing a large volume of water, keeping it hot and ready for use. For homes with this type of heater, natural gas tends to be the more economical option. According to research, running a gas-powered storage water heater typically costs about half as much as running an electric model, based on energy consumption.

While gas models are generally more expensive upfront compared to electric units, the savings in energy costs typically allow homeowners to recoup the initial price difference within about a year. However, local utility rates can affect this, so it’s always wise to check current gas and electricity costs in your area before making a decision.

Tankless Water Heaters

Tankless water heaters, in contrast, heat water on demand instead of storing it. These systems are highly efficient, as they only activate when hot water is needed, eliminating standby energy losses common with tank-style heaters. For those considering a tankless system, gas models may offer better long-term savings on fuel costs, as natural gas tends to be less expensive than electricity.

However, the story doesn’t end there. While gas tankless water heaters save homeowners about 10-15% in annual energy costs compared to electric tankless units, their peak efficiency rates are lower. Gas tankless heaters typically operate at 80-85% efficiency, whereas electric tankless models can reach up to 98% efficiency. This difference can narrow the energy savings, making it important to consider how much hot water your household consumes and how often it’s used simultaneously.

For homes with older electrical systems, upgrading to an electric tankless water heater may require expensive rewiring to meet the power demands. In such cases, the cost of upgrading your home’s electrical capacity could outweigh the benefits of switching from gas to electric.

Energy Efficiency and Savings Potential

Water heating is responsible for about 20% of your home’s monthly energy costs, making it the second most expensive system to run, after heating and cooling. Recently, the Department of Energy introduced higher efficiency standards for water heaters, giving both gas and electric models a boost.

For storage tank models under 55 gallons, these new regulations result in a 4% improvement in efficiency. Larger models, with capacities of 55 gallons or more, offer even more significant savings, with a 25-50% efficiency increase depending on the specific technology used. This translates into substantial long-term savings on your energy bill, particularly if you select a unit that utilizes a more affordable fuel source.

Additionally, turning down the water heater’s thermostat by just 10 degrees Fahrenheit can net another 3-5% in energy savings. These small adjustments, combined with choosing the right fuel source, can help you save significantly over time.

Should You Choose Gas or Electric?

When deciding between a gas or electric water heater, it’s important to weigh the costs, efficiency, and potential savings each option provides:

• Upfront Costs: Gas water heaters generally have a higher upfront cost but can offer better long-term savings due to lower fuel costs.
• Energy Efficiency: Electric water heaters—especially tankless models—tend to be more efficient but can be more expensive to operate, depending on electricity rates in your area.
• Installation: Gas models may require venting and proper gas lines, while electric heaters may need electrical upgrades, particularly for tankless models.
• Maintenance: Gas water heaters tend to require more frequent maintenance, such as checking gas lines and venting, whereas electric models are typically easier to maintain.
• Location: If your area has higher natural gas prices or if your home is not equipped for gas, electric may be the better option. Conversely, if gas is affordable and readily available, it could save you more in the long run.
