Are Tankless Water Heaters Worth It: Costs, Installation, & Benefits
In this comprehensive guide, we’ll delve into the world of tankless water heaters, examining their benefits, installation process, and associated costs. By the end, you’ll clearly understand whether a tankless water heater aligns with your needs and preferences.
Understanding Tankless Water Heaters:
In the 1990s, tankless water heaters began gaining traction in residential and commercial applications. Advances in electronics, controls, and heat exchanger materials contributed to increased efficiency and performance. As environmental concerns grew, the energy-saving benefits of tankless models became more appealing.
Also referred to as on-demand water heaters, these innovative systems provide hot water only when needed, eliminating the necessity for storage in traditional tank water heaters. Unlike traditional water heaters, which maintain a continuous hot water supply, tankless heaters heat water directly as it flows through, offering impressive energy efficiency and space-saving advantages.
How Do Tankless Water Heaters Work?
As you open the hot water tap, cold water flows into the tankless water heater through an inlet pipe. Flow sensors activate the heater, where the water encounters the heat exchanger. A controlled flame heats the water around the exchanger in a gas model. In contrast, in an electric model, heating elements do the job.
Swirling through this chamber, the water reaches your desired temperature, regulated by the unit’s controls. Exiting the heat exchanger through an outlet pipe, the now-heated water heads for the shower, providing a continuous stream of warmth. After use, the tankless heater goes into standby mode, conserving energy until needed again.
This results in a continuous hot water supply without the concern of running out, a challenge often faced with tankless model other-style water heaters.
The Benefits of Tankless Water Heaters:
Now, let’s uncover the array of advantages that these tankless water heaters tend to bring to the table:
Energy Efficiency:
Among their most striking benefits, tankless water heaters excel in energy efficiency. Tankless water heaters are generally 24% to 34% more energy-efficient than traditional storage tank water heaters. Traditional heaters tend to maintain hot water even during periods of non-use, causing standby heat loss. In contrast, tankless heaters heat water on demand, eliminating standby heat loss.
Tankless water heaters can achieve an 80-98% thermal efficiency, indicating the percentage of input energy effectively converted into hot water. This energy-efficient move translates to lower energy consumption and reduced utility bills.
Unlimited Hot Water:
Tankless water heaters provide a consistent stream of hot water as long as there’s demand. This stands in contrast to conventional storage tank water heaters, which can exhaust their hot water supply once the whole tank water heater is depleted.
Space Utilization:
Tankless water heaters are ideal for homes with limited space, as they are compact and wall-mounted. This is a notable departure from their bulkier traditional counterparts with storage tanks and other condensing tankless water heaters models.
Longevity:
Another compelling advantage of tankless water heaters is their extended lifespan. While they might entail a higher upfront cost, their durability means less frequent replacements, ultimately leading to long-term savings.
The average lifespan of a tankless water heater is approximately 20 years, while traditional tank heaters tend to last around 8-10 years.
Maintaining Your Tankless Water Heater:
Let’s shift our focus to maintenance considerations for tankless water heaters, recognizing their unique design:
Flushing the System:
The buildup of minerals, especially in areas with hard water, can impede the efficiency of a tankless water heater. Regularly flushing the tankless system is essential to expel mineral deposits and ensure optimal operation.
Tankless units require more frequent flushing than tanked water heaters due to their on-demand water heating only mechanism. This prevents the accumulation of minerals like calcium and magnesium within the heat exchanger.
Checking for Leaks:
Routine leak checks for connections and pipes are essential to prevent potential water damage, as with any plumbing system.
Fortunately, tankless water heaters are less prone to leaks than traditional ones due to their lack of a large stored water volume. This absence of stagnant tankless water heaters reduces the likelihood of leaks over time.
Referring to the Manual:
Each tankless water heater model may have specific maintenance guidelines outlined in the manufacturer’s manual. Regular consultation with the manual ensures proper adherence to maintenance tasks and schedules.
Professional Inspection:
Enlisting the expertise of an experienced technician for an annual tankless water heater maintenance and inspection is a wise decision. This guarantees the system’s optimal function and early detection of potential issues.
Navigating Tankless Water Heater Installation:
Let’s address the critical aspects of the new tankless water heater and installation, ensuring a seamless transition:
Installation Time:
The duration of a tankless water heater installation varies based on factors like unit type, installation complexity, and the proficiency of the installation team. On average, a professional installation of gas and electric units or a tankless water heater can span 4 to 8 hours.
Size Matters:
Accurate sizing is pivotal for a tankless tank water heater here. A technician will assess your hot water requirements, and fixture count to ensure the unit matches your needs.
Gas or Electric Tankless Water Heater:
Tankless water heaters offer gas and electric options. The choice hinges on your home’s energy source and specifications.
Gas: Gas-powered tankless water heaters are known for their higher flow rates, making them suitable for larger households. However, they require access to gas lines and proper ventilation for safety.
Electric: Electric tankless water heaters are easier to install and are a great fit for smaller households. Keep in mind that they might struggle to meet high hot water demand scenarios.

Ventilation Considerations:
Proper venting is vital for gas-powered tankless heaters to discharge combustion byproducts safely. This aspect demands meticulous planning during installation.
Strategic Placement:
Tankless heaters are often installed near points of use, minimizing the wait for hot water. Adequate ventilation and maintenance access in the chosen installation area is essential.
Professional Touch:
Given the intricacy of installation, a skilled technician is advisable. Their expertise guarantees a flawless installation, mitigating potential future issues.
Tankless Water Heater Cost:
Next, let’s talk about tankless water heater costs and what that means for you.
Investment Breakdown:
Tankless water heaters typically carry a higher initial cost than traditional tanked water heater models. On average, the total cost for a tankless water heater installation can range from $4,500 to $6,500 or more. This encompasses the unit, installation charges, and potential home infrastructure modifications.
Installation Expenses:
The installation cost fluctuates based on unit type, location, and installation complexity.
Long-Term Gains:
While the upfront investment may seem steeper, tankless water heaters offset this through energy savings, reducing long-term expenses. Lower energy bills and decreased maintenance contribute to these enduring financial benefits.
