Gas vs Electric Water Heater: Which One Should You Choose?

Understanding the Basics

In most homes, the choice between gas and electric water heaters is already determined by the existing setup. A house will usually have either a gas line or an electrical connection for the water heater, and switching between the two is nearly impossible. Because of this, most homeowners don’t truly get to choose.

When replacing a unit, the upgrade depends on the current system. For homes with an electric model, a hybrid water heater is usually the best choice. For homes with gas, a larger tank or a tankless gas system is often the preferred option.

Cost and Efficiency Comparison

When choosing between gas and electric water heaters, it helps to look beyond just the initial cost. Each type comes with its own operating costs, maintenance needs, and energy performance. All these factors are important in understanding how much you spend over time and how well the system fits your home. Comparing cost and efficiency is the first thing that comes to mind when deciding what to choose. 

Upfront and Installation Costs

Gas water heaters usually have a higher upfront cost because of the need for a gas line, venting, and additional safety components. Installation can be more labor-intensive and therefore pricier. Electric hot water heaters, on the other hand, are usually less expensive to purchase and install, as they only require proper wiring and a compatible outlet. This makes electric models more budget-friendly initially, but it’s important to remember that installation savings may be offset over time by higher operating costs. That depends on energy prices in your region and how much you use your heater. 

Energy Efficiency and Utility Bills

Gas hot water heaters usually have better energy efficiency because natural gas costs less per unit than electricity. This means lower monthly utility bills. Many households spend around $30 to $50 per month for gas. Electric hot water heaters are often cheaper to purchase and install, but generally use more energy.  Their operating costs are often $40 to $70 per month. Regardless of the type, other factors like tank size, insulation quality, and design efficiency are also important. 

Long-Term Savings Potential

Water heater electric models can offer long-term savings in areas where renewable energy, like hydroelectric power, keeps electricity costs low. On the other hand, gas hot water heaters are a good choice for bigger homes or those who need more hot water. Their lower monthly fuel cost and reliable performance can make them more economical over time. Overall, it depends on your local utility rates and home size. 

Performance and Capacity

When comparing water heater options, it’s important to think about how well each type can keep up with your household’s hot water needs. Performance depends on how quickly the unit can heat water. Capacity determines how much it can supply at once. Both factors are important if you want to feel comfortable using hot water.

Recovery Rate and Heating Speed

Natural gas water heaters usually heat water faster because their burners provide direct, concentrated heat at the tank’s base. This gives them a good recovery rate, allowing them to replenish a full tank in roughly an hour. Hot water heater electric options are slower to heat. It’s important to note that in most homes, the choice between gas and electric isn’t flexible – your setup is determined by the existing connection. If your home has a gas line and venting, you’ll be limited to gas models. If it only has an electrical hookup, you’ll need an electric or hybrid system. You can choose if you have both an electrical connection and a gas line. 

Tank Sizes and Flow Rates

Electric water heaters are usually more compact, so they’re suitable for smaller homes or areas with limited installation space. They also don’t require extensive ventilation, so you can place them in many different places. But they still need to be positioned near an outlet. Gas water heaters require additional clearance for ventilation and space for vent pipes. These requirements leave you with fewer places suitable for installation. Tankless gas units can help save space, but the flow rates may dip if many appliances are used at once.

What Size Water Heater Do I Need for My Family?

For most families, a 40-50 gallon tank works well for 3-4 people, covering daily showers, dishwashing, and laundry. Smaller households of 1-2 people can usually manage with a 30-40 gallon tank. Large families of 5 or more may need 60-80 gallons. If you choose a tankless model, look for a unit with a flow rate of 7-11 gallons per minute.

Installation and Maintenance Needs

Installing and maintaining a water heater is a bit more than just placing the unit in your home. Both electric and gas models have specific setup requirements, safety considerations, and maintenance needs to keep them running correctly. Proper installation is also important for performance, just as much as regular maintenance. The exact needs will vary depending on the type of water heater you choose.

Space and Venting Requirements

Gas water heaters require ventilation to release exhaust, meaning they need more installation space and proper venting systems. This limits where they can be placed in the home. Electric water heaters don’t produce combustion gases so they don’t require venting. This makes them more flexible for placement, especially in smaller or enclosed areas. Gas models are usually larger in size and take up more room, while electric units can fit in tighter spots but must be located near an electrical outlet. 

Routine Maintenance Requirements

Gas water heaters should have regular checks on the pilot light, venting system, and gas lines. Electric water heaters require monitoring of the heating element and thermostat. Their specific upkeep tasks differ, but both types also require general maintenance like flushing the tank to remove sediment and testing the pressure relief valve.

Expected Lifespan and Reliability

Gas water heaters usually last about 8 to 12 years. They may require more frequent maintenance, but with proper care, they can remain dependable throughout their service life. Electric tank water heaters can have a longer lifespan, about 10 to 12 years, with the possibility of lasting even longer if well-maintained. Their design has fewer parts exposed to combustion, which can make them more consistent over time since they do not rely on combustion to heat water. All in all, electric models usually offer slightly better long-term reliability when kept in good working condition.
