What Is the Average Price of a Tankless Water Heater?
The average price of a tankless water heater unit, without installation, ranges from $700 to $2,500 depending on the size, brand, and features. Installation can add another $500 to $3,500 or more, making the total cost to $1,200 to $6,000.
Understanding Tankless Water Heaters
Tankless water heaters, also known as on-demand water heaters, have revolutionized the way homeowners access hot water. Unlike traditional tank-based heaters that constantly heat and store water, tankless systems heat water only when a hot water tap is turned on. This offers several potential advantages but also comes with specific cost considerations.
Benefits of Tankless Water Heaters
Opting for a tankless water heater comes with a range of benefits:
- Endless Hot Water: Enjoy consistent hot water supply without worrying about running out during peak usage.
- Energy Efficiency: Because they only heat water when needed, tankless heaters can be more energy-efficient than traditional tank heaters, potentially leading to lower energy bills.
- Space Saving: Tankless units are typically smaller than tank heaters, freeing up valuable space in your home.
- Longer Lifespan: Tankless water heaters often last longer than tank heaters, typically 20 years or more, compared to the 10-15 year lifespan of a traditional tank.
Key Factors Influencing the Price
Several factors influence the cost of a tankless water heater and its installation:
- Size (Gallons Per Minute – GPM): The GPM rating determines how much hot water the unit can deliver simultaneously. Larger homes with higher hot water demands require higher GPM ratings, increasing the price.
- Fuel Type: Electric tankless water heaters generally have a lower upfront cost but may have higher operating costs depending on local electricity rates. Gas-powered units are often more expensive initially but can be cheaper to operate.
- Brand and Features: Well-known brands with advanced features like digital displays, self-diagnostics, and remote control capabilities tend to command higher prices.
- Installation Complexity: Installation costs vary depending on factors such as existing plumbing, electrical wiring upgrades, and ventilation requirements. Replacing an existing tank with a tankless heater in the same location is generally less expensive than a new installation or relocating the water heater.
Installation Process and Costs
The installation of a tankless water heater can be complex and often requires a professional plumber or HVAC technician. The installation process typically involves:
- Removing the Old Tank: If replacing an existing tank heater, the old unit must be drained and removed.
- Plumbing Modifications: Alterations to the existing plumbing may be necessary to accommodate the tankless unit’s connections.
- Electrical or Gas Line Connections: Depending on the fuel type, the unit needs to be connected to either an electrical circuit with appropriate amperage or a gas line with sufficient capacity.
- Ventilation (for Gas Units): Gas tankless heaters require proper ventilation to exhaust combustion byproducts safely. This may involve installing or modifying venting systems.
- Testing and Calibration: After installation, the unit must be tested and calibrated to ensure proper operation and optimal efficiency.
Common Mistakes to Avoid
When considering a tankless water heater, avoid these common mistakes:
- Underestimating Hot Water Needs: Accurately assess your household’s hot water demand to choose a unit with the appropriate GPM rating.
- DIY Installation: Improper installation can lead to safety hazards, equipment damage, and void warranties. Always hire a qualified professional.
- Ignoring Local Codes and Regulations: Ensure that the installation complies with all local building codes and regulations.
- Neglecting Maintenance: Regular maintenance, such as flushing the unit to remove mineral buildup, is essential for prolonging its lifespan and maintaining its efficiency.

Frequently Asked Questions (FAQs)
What is the typical lifespan of a tankless water heater?
Tankless water heaters generally last much longer than traditional tank water heaters, typically around 20 years or more with proper maintenance. Tank heaters, on the other hand, usually last between 10 and 15 years.
Are tankless water heaters truly more energy-efficient?
Yes, in many cases. Tankless heaters only heat water when you need it, eliminating the standby heat loss associated with tank heaters. However, actual energy savings depend on your hot water usage habits and the efficiency of the specific models compared.
Can I install a tankless water heater myself?
While it might seem tempting to save on installation costs, it’s generally not recommended to install a tankless water heater yourself. These systems require specialized plumbing and electrical/gas connections, and improper installation can be dangerous and void the warranty.
What size tankless water heater do I need?
The size of the tankless water heater depends on your household’s hot water demand, measured in gallons per minute (GPM). To determine the appropriate size, estimate the maximum number of hot water fixtures you might use simultaneously (showers, faucets, dishwashers, etc.) and add their GPM ratings together.
Do I need to upgrade my electrical panel for an electric tankless water heater?
In many cases, yes. Electric tankless water heaters often require a significant amount of amperage, and your existing electrical panel may not be able to handle the load. An electrician can assess your panel and determine if an upgrade is necessary.
What kind of maintenance do tankless water heaters require?
Tankless water heaters require periodic maintenance to ensure optimal performance and longevity. The most common maintenance task is flushing the unit with vinegar to remove mineral buildup, which can reduce efficiency and damage the heater. It’s generally recommended to flush the unit once a year, or more frequently if you have hard water.
Are there any rebates or tax credits available for tankless water heaters?
Many utility companies and government agencies offer rebates or tax credits for energy-efficient appliances, including tankless water heaters. Check with your local utility company and state energy office to see what incentives are available in your area.
Are tankless water heaters noisy?
Some tankless water heaters, particularly gas models, can produce some noise during operation. However, the noise level is generally not excessive and is often comparable to other household appliances.
What are the advantages of a gas vs. an electric tankless water heater?
Gas tankless water heaters typically have a higher upfront cost but can be cheaper to operate in areas with lower natural gas prices. They also tend to provide a higher GPM flow rate. Electric tankless water heaters have a lower upfront cost but may be more expensive to operate, especially in areas with high electricity rates.
What are the disadvantages of a tankless water heater?
While tankless water heaters offer many benefits, they also have some potential drawbacks. They typically have a higher upfront cost than tank heaters, and installation can be more complex. Some users may also experience a slight delay in hot water delivery, known as the “cold water sandwich.”
What is the best brand of tankless water heater?
There are several reputable brands of tankless water heaters, including Rheem, Rinnai, Navien, and Bosch. The best brand for you will depend on your specific needs and budget. Research different models and read reviews before making a purchase. Consider factors like warranty, features, and customer support.
What is the average price of a tankless water heater including all expenses?
Considering both the unit itself and the installation costs, What Is the Average Price of a Tankless Water Heater? will fall in the range of $1,200 to $6,000 or more. The final price is heavily influenced by the unit’s complexity, local labor rates, and necessary modifications to plumbing or electrical systems. Getting quotes from multiple qualified installers is crucial for an accurate estimate.
