Electric vs Gas Tankless Water Heater: Differences
Tankless water heaters are becoming increasingly popular due to their energy efficiency and cost savings. When choosing between an electric and gas tankless water heater, there are several differences to consider.
Firstly, the primary difference between the two is the type of fuel they use. Electric tankless water heaters rely on electricity to heat water, while gas tankless water heaters use natural gas or propane.
Secondly, electric tankless water heaters typically have a lower upfront cost and are easier to install, as they do not require venting. They may not be as powerful as gas tankless water heaters and can have higher operating costs, depending on the cost of electricity in your area.
Thirdly, gas tankless water heaters are generally more expensive upfront and require professional installation and venting. They are often more powerful and can provide hot water to multiple appliances simultaneously. They may also have lower operating costs, depending on the cost of gas in your area.
Fourthly, the decision between an electric and gas tankless water heater will depend on your specific needs and preferences. Consider factors such as upfront costs, installation requirements, and operating costs when making your decision.
Gas vs Electric Tankless Water Heater: The Key Features Comparison
Energy Efficiency
Electric tankless water heaters are more energy-efficient than gas models since they only use energy when hot water is needed, whereas gas models maintain a pilot light and use energy even when no hot water is needed.
On the other hand, gas models can be more energy-efficient during periods of high hot water demand, such as when multiple people are showering at the same time.
Initial Cost
Electric tankless water heaters are generally less expensive than gas models, but they may require an upgrade to the home’s electrical system to accommodate the increased electrical load.
Gas models, on the other hand, require a gas line, venting, and a larger upfront investment.
Maintenance
Electric models generally require less maintenance than gas models since they have fewer moving parts, and there is no need for annual cleaning of burners and ventilation.
Durability
Gas models tend to have a longer lifespan than electric models, with some gas models lasting up to 20 years. Electric models typically have a lifespan of 10-15 years.
Capacity
Gas tankless water heaters have a higher capacity for providing hot water at a faster rate than electric models. This is because gas models can heat water more quickly than electric models.
Electric vs Gas Tankless Water Heater: The Choosing Factors
1. Fuel source availability- The first factor to consider is the fuel source availability in your area. If your house is already set up for natural gas or propane, a gas tankless water heater may be the more efficient and cost-effective option. On the other hand, if your house does not have a gas line, an electric tankless water heater may be the only choice.
2. Energy efficiency- Both electric and gas tankless water heaters are energy-efficient, but gas models tend to be more efficient. Gas models have a higher energy factor (EF) rating, which measures the unit’s overall efficiency. On the other hand, electric models have a lower EF rating due to energy losses during transmission and conversion.
3. Installation cost- The installation cost of an electric tankless water heater is generally lower than that of a gas model. Electric models require less complex venting and gas line installation, which can lead to savings in installation costs.
4. Operating cost- The operating cost of a tankless water heater is also an important factor to consider. Gas models generally have lower operating costs due to the lower cost of natural gas compared to electricity.
5. Flow rate- The flow rate of a tankless water heater refers to the amount of hot water that the unit can produce per minute. Electric models generally have a lower flow rate than gas models, which can be a disadvantage for larger households.
Electric vs Gas Tankless Water Heater: Maintenance
1. Flushing the unit: Both electric and gas tankless water heaters require periodic flushing to prevent mineral buildup and maintain efficiency. The frequency of flushing depends on the water hardness in your area and usage levels.
2. Venting and gas line maintenance: Gas tankless water heaters require regular venting and gas line maintenance to ensure proper functioning and safety. This includes checking for leaks, inspecting the venting system, and cleaning the burners.
3. Electrical maintenance: Electric tankless water heaters also require electrical maintenance, including checking for loose connections and replacing any damaged components. It’s important to have a

Another advantage of gas tankless water heaters is that they have a longer lifespan than electric models, with an average lifespan of up to 20 years. Gas models also tend to be more energy efficient than electric models, meaning they can save you money on your energy bills in the long run.
They do require a larger upfront investment due to the cost of installation and venting requirements.
Electric vs. Gas Tankless Water Heater: Installation
Step 1: Understanding the Difference Between Electric and Gas Tankless Water Heaters
Electric and gas tankless water heaters have some distinct differences. An electric tankless water heater uses electricity to heat the water, while a gas tankless water heater uses natural gas or propane to heat the water. Electric tankless water heaters are generally more efficient but have a lower flow rate, while gas tankless water heaters have a higher flow rate but may be less efficient.
Step 2: Choosing the Right Size Water Heater
Before installing a tankless water heater, it is important to determine the right size for your household. This will depend on your water usage, climate, and the number of people in your household. Generally, a smaller household can opt for a smaller tankless water heater, while larger households will require a larger unit.
Step 3: Preparing for Installation
Before installation, you will need to prepare the space where the tankless water heater will be installed. Make sure the area is clear and clean, and that there is enough ventilation for gas units. You will also need to turn off the water and gas or electricity supply.
Step 4: Installing the Water Heater
To install a tankless water heater, you will need to follow the manufacturer’s instructions carefully. For electric units, you will need to connect the unit to the electrical supply and mount it securely to the wall. For gas units, you will need to connect the gas supply and ventilation and mount the unit securely to the wall.
Step 5: Connecting the Water Supply
Once the unit is securely mounted, you can connect the water supply. This will involve attaching the hot and cold water pipes to the unit using the appropriate fittings.
Step 6: Testing and Inspecting the Water Heater
After installation, it is important to test and inspect the water heater to ensure it is working correctly. Check for leaks and ensure that the water temperature is correct. It is also a good idea to schedule regular maintenance to keep the unit functioning efficiently.
Electric vs Gas Tankless Water Heater: Disadvantages
Electric models typically have a lower flow rate compared to gas models, making them less suitable for larger households or homes with high water demand. Also, electric models may require a larger electrical supply or circuit breaker to operate efficiently, which can increase installation costs.
Gas models, on the other hand, require proper venting and gas lines, which can add to the installation costs. They also have a higher upfront cost compared to electric models.
Gas models may require more maintenance than electric models due to the presence of a pilot light and the need for regular venting inspections.
