Signs It's Time to Replace Your Tankless Water Heater
Even the most advanced Water Heaters have a lifespan. If you're experiencing any of the following issues, it might be time to consider replacing your tankless unit:
- Advanced Age: While tankless heaters last longer than tank models (often 20+ years with proper maintenance), performance declines over time. An older unit is more prone to failure and less energy-efficient than newer models.
- Frequent Breakdowns: Are you calling for Water Heater Repair more often? Constant issues like error codes, ignition problems, or flow sensor failures signal that the unit is nearing the end of its functional life and replacement may be more cost-effective than ongoing repairs.
- Inconsistent Hot Water: If your "endless" hot water supply is becoming unreliable, fluctuating in temperature, or taking longer to heat, your unit's components may be failing.
- Corrosion or Leaking: Visible rust, corrosion around connections, or actual leaks are serious signs of internal damage. Leaks can cause significant damage to your property and often indicate irreversible system failure.
- Reduced Efficiency: Over time, mineral buildup (scaling) or failing components can significantly reduce your tankless heater's energy efficiency, leading to unexpectedly high gas or electric bills.
- High Repair Costs: If a single repair costs a significant percentage of a new unit's price, replacement is usually the wiser investment.

Benefits of Upgrading to a New Tankless Water Heater
Investing in a new tankless water heater isn't just about solving current problems; it's about enhancing your home's comfort, efficiency, and value. Modern tankless units offer significant advantages:
- Energy Efficiency: Newer models are highly efficient, only heating water as needed. This can lead to substantial savings on energy bills compared to older tankless units or traditional tank heaters.
- Endless Hot Water: Enjoy a continuous supply of hot water, ideal for large families or simultaneous use of multiple fixtures.
- Extended Lifespan: With proper maintenance, new tankless units are built to last 20 years or even longer.
- Space Savings: Tankless heaters are compact and can be mounted on a wall, freeing up valuable floor space compared to bulky tanks.
- Improved Reliability: New systems feature advanced technology and are less prone to the issues common in aging units.
Replacing Tankless vs. Upgrading from a Tank Unit
The replacement process can differ depending on whether you're replacing an existing tankless system or upgrading from a traditional tank water heater.
- Tankless-to-Tankless Replacement: This is often a more straightforward process as the necessary utility connections (gas line size, electrical, venting type) are usually already in place. Our technicians assess your existing setup and recommend a new unit that aligns with your home's hot water demands and the existing infrastructure. We handle the safe disconnection and removal of the old unit, installation of the new one, reconnection of water, gas, and electrical lines, and verify proper venting.
- Tank-to-Tankless Upgrade: This involves more complex modifications. Traditional tank heaters have different venting requirements, use different water pipe sizes, and often don't have the correctly sized Gas Lines or dedicated electrical circuits required for tankless operation. Our team expertly assesses your home's current setup and performs all necessary modifications, including:
- Upgrading Gas Lines to ensure sufficient flow.
- Adding or modifying electrical connections for ignition and controls.
- Installing appropriate venting (often requiring new wall penetrations or rooftop terminals).
- Making necessary changes to water piping.
- Installing a condensate drain for high-efficiency condensing units.
We ensure all modifications meet current plumbing and safety codes for Abilene, TX, ensuring a safe and efficient installation.

Understanding Tankless Water Heater Replacement Cost
The cost of replacing a tankless water heater or upgrading from a tank unit varies widely based on several factors, typically ranging from $1,800 to $6,000 or more. Key factors influencing the final price include:
- Type and Size of New Unit: Higher capacity or more feature-rich units cost more.
- Fuel Type: Gas tankless heaters are generally more expensive than electric units and may require more complex venting or gas line work.
- Complexity of Installation/Modifications: Upgrading from a tank unit usually costs more due to the need for significant modifications to gas lines, electrical, and venting. Relocating the unit also adds complexity and cost.
- Labor Costs: Vary based on the complexity and time required for the job.
- Permits: Required permits add to the overall cost.
- Disposal: Cost associated with the safe removal and disposal of the old unit.
For an accurate estimate tailored to your specific home and needs, we recommend scheduling an in-home consultation.
