| National average cost range | $704-$2,031 |
|---|---|
| Low-end cost | $336 |
| High-end cost | $4,329 |
Electric tankless water heater installation cost
Installing an electric tankless water heater typically costs between $718 and $2,094. While this is slightly higher than the average cost to install a traditional electric storage-tank water heater ($689-$1,967), many homeowners find the added expense worthwhile for the potential energy savings and space-saving design.
Several factors can affect the final installation cost, including the unit's size and capacity, the number of fixtures it needs to serve, local labor rates, and whether electrical upgrades are required. Because tankless systems draw a significant amount of power, some homes may need new dedicated circuits, upgraded wiring, or an electrical panel upgrade, which can increase the overall project cost.
Although the upfront installation cost is often higher, electric tankless water heaters can provide long-term benefits, including lower energy consumption and a longer lifespan than many traditional tank models. They can also provide a continuous supply of hot water.
However, it's worth noting that electric tankless units generally have lower flow rates than gas models, making them best suited for smaller households or homes with moderate hot water demand. Larger households with high simultaneous demand may want to consult a pro about whether an electric tankless unit is adequately sized for their needs.
Cost breakdown
What affects the cost of electric water heater installation?
Several key factors influence the total cost of your electric water heater installation.
- Heater size and type: Larger tanks or more complex models like tankless or hybrid heaters generally cost more for both the unit and the installation labor. For example, replacing a standard 40-gallon tank is often less expensive than installing a new 80-gallon unit.
- Labor: Labor rates vary by your location and the professional's experience level. A complex installation that requires more time or specialized skills will increase the labor portion of your bill.
- Geographic location: Installation costs are often higher in urban areas where the cost of living is greater compared to rural regions.
- Accessibility: If your water heater is in a hard-to-reach spot, such as a tight closet or attic, the job may take longer and cost more. Easy access in a garage or basement can help reduce labor time.
- System modifications and repairs: Your final price might increase if the project requires new plumbing lines, electrical circuit upgrades, or a new vent system. You should check local codes or consult a licensed professional to ensure your setup is compliant.
- Urgency of replacement: Emergency or after-hours service calls typically come with premium charges. If possible, planning your replacement ahead of time may help you avoid these extra fees.
- Old unit disposal: Most professionals include the cost of removing and disposing of your old water heater in their quote, but it is a good idea to confirm. This service can sometimes be a separate line item on your final bill.
DIY vs. hiring a pro to install an electric water heater
Deciding whether to install an electric water heater yourself or hire a professional involves weighing potential cost savings against the risks and complexity of the job. Each path has its own set of benefits and drawbacks that can affect your budget and peace of mind.
DIY:
- You may save on labor costs, but you will still need to purchase or rent the necessary tools, such as pipe cutters, a soldering torch, and a multimeter, in addition to the heater itself.
- This project requires a solid understanding of both plumbing and electrical work. Common mistakes, like faulty wiring or improper pipe connections, can lead to serious risks like water leaks, electrical shorts, or fire hazards.
- A DIY approach might be suitable if you have previous experience, are replacing an identical unit in the same location, and no modifications to your plumbing or electrical systems are needed.
Hiring a pro:
- Though the upfront cost is higher due to labor, a professional’s experience often ensures the job is done correctly and efficiently. They can also troubleshoot unexpected issues that may arise during installation.
- Licensed professionals typically carry liability insurance and may offer a warranty on their workmanship. This can protect you financially if something goes wrong with the installation.
- A pro can help ensure the installation complies with all local building and safety codes, which is crucial for safety and may be required for home insurance purposes. You should always check local codes or consult a licensed professional.
- Hiring a professional is strongly recommended for complex installations, such as upgrading to a larger or different type of unit, moving the heater’s location, or if the job requires modifications to your home’s electrical circuits or plumbing lines.

How to save money on electric water heater installation
While a new electric water heater is a significant investment, there are several ways you might lower the overall installation cost. A little planning can often lead to meaningful savings without cutting corners on safety or quality.
- Get multiple quotes. Contacting several licensed professionals allows you to compare their prices and services. This can help you find a fair market rate for your project, but remember to compare the scope of work, not just the final price.
- Choose the right time for installation. If your current heater is still working, you can schedule the installation during a professional’s off-season, which might result in lower labor rates. Avoiding emergency or after-hours service calls can often save you from premium charges.
- Bundle with other projects. If you have other plumbing or electrical work that needs to be done, you might save on labor by having it all completed in one visit. A professional may offer a better rate for a larger job than for multiple small service calls.
- Select a suitable unit. You might not need the most expensive, feature-rich model. A mid-range, energy-efficient unit can often provide a good balance between upfront cost and long-term savings on your utility bills.
- Clear the work area. Ensuring the path to your water heater and the surrounding area is clear can reduce the time a professional spends on the job. This simple step may lower the total labor hours you are billed for.
- Get the scope in writing. A detailed, written contract that outlines all costs, including the unit, labor, parts, and disposal of the old heater, can prevent surprise fees. This ensures you and the professional agree on the full scope of the project before work begins.
FAQs
What's the typical cost to install an electric water heater?
The national average cost for an electric water heater installation is between $704 and $2,031. However, your final price can vary. Factors like the heater's size, necessary plumbing or electrical updates, and local labor rates will determine your specific cost.
Do I need a permit to install an electric water heater?
In many areas, a permit is required for water heater installation to ensure the work complies with local building and safety standards. A licensed professional can often manage the permitting process as part of their service. You should always check local codes or consult a licensed professional to understand the specific requirements in your area.
How does maintenance affect the long-term cost of an electric water heater?
Regular maintenance, such as flushing the tank to remove sediment, can extend your heater's lifespan and keep it running efficiently. This simple task may delay the need for a costly replacement and can help lower your energy bills over time. Neglecting maintenance might lead to premature failure, resulting in unexpected replacement costs sooner than anticipated.
Does my location affect the installation price?
Yes, your geographic location significantly influences installation costs, primarily due to differences in labor rates. Professionals in urban areas with a higher cost of living often charge more than those in rural regions. Additionally, the accessibility of the unit within your home can also affect the final price, as difficult-to-reach spaces may require more labor.
How should I decide between a basic and a high-end electric water heater?
Choosing between a basic and a high-end model often comes down to balancing upfront cost with long-term savings. A standard tank heater is typically more affordable to purchase and install, making it a good budget-friendly option. More advanced units, such as hybrid or tankless models, cost more initially but may reduce your energy bills over their lifespan, offering a better return on investment if you plan to stay in your home for many years.
