Why Greater Metro Atlanta Homeowners Are Switching to Tankless Water Heaters
Experience Endless Hot Water with America’s #1 Tankless System
Transform your home’s comfort with on-demand hot water technology that eliminates the limitations of traditional tank systems. Rinnai® tankless water heaters provide an unlimited supply of perfectly heated water exactly when and where you need it—even during simultaneous use at multiple fixtures throughout your home.
No more scheduling showers around laundry. No more lukewarm dishwashing after bath time. No more running out of hot water during family visits. With professional tankless water heater installation from Atlanta’s certified Rinnai® specialists, your home enjoys:
Superior Energy Efficiency & Lower Utility Bills
Rinnai’s advanced tankless technology features precision-engineered copper heat exchangers that deliver maximum thermal efficiency while consuming up to 40% less energy than conventional tank water heaters. This significant efficiency improvement translates directly to lower monthly utility bills and reduced environmental impact.
Atlanta homeowners typically save $100-$200 annually on energy costs after professional tankless water heater installation, with savings continuing throughout the system’s extended lifespan. The innovative on-demand heating design eliminates the constant energy waste of maintaining a large tank of hot water 24/7.
On-Demand Operation for Maximum Energy Savings
Unlike traditional water heaters that continuously heat and reheat stored water—even when you’re not using it—tankless systems operate only when hot water is needed. This on-demand functionality eliminates standby energy losses that account for up to 20% of water heating costs in conventional systems.
The advanced electronic ignition system replaces outdated standing pilot lights, further reducing energy consumption and enhancing safety. This intelligent design ensures you’re only paying to heat water you actually use, making tankless technology the smart choice for energy-conscious Atlanta homeowners.
Increase Your Atlanta Home’s Value & Qualify for Incentives
Professional tankless water heater installation represents a smart long-term investment in your Atlanta property:
- Enhanced Home Value – Tankless systems typically increase property values by 4-6% compared to homes with conventional water heaters
- Improved Energy Ratings – Lower your Home Energy Rating System (HERS) Index Score and optimize LEED certification potential
- Available Tax Credits – Federal tax incentives of up to $300 for qualifying energy-efficient tankless installations
- Local Utility Rebates – Georgia natural gas providers offer rebates of $200-$500 for qualifying tankless water heater installations
- Extended Warranty Protection – Transferable warranty coverage adds value when selling your home
Our tankless water heater specialists will help you navigate available incentives to maximize your return on investment and minimize upfront costs.
Customized Solutions for Every Atlanta Home
Rinnai’s comprehensive product line offers multiple capacity options to perfectly match your household’s specific hot water demands:
- Compact Models – Ideal for smaller homes, condos, and apartments with limited space
- Mid-Range Systems – Perfect for average-sized Atlanta homes with 1-2 bathrooms
- High-Capacity Units – Engineered for larger homes with multiple bathrooms and high-demand applications
- Commercial-Grade Options – Available for businesses and multi-family properties
Our certified tankless water heater specialists conduct a thorough assessment of your home’s hot water requirements, ensuring you receive the perfectly sized system for optimal performance and efficiency. This customized approach prevents both undersizing (inadequate hot water) and oversizing (unnecessary expense).
Modular Design for Extended Lifespan & Reduced Waste
Unlike conventional water heaters that typically require complete replacement every 8-12 years, Rinnai tankless systems feature a modular design where individual components can be serviced or replaced as needed:
- Serviceable Parts – Heat exchangers, burners, and electronic components can be individually maintained
- Extended Lifespan – Properly maintained tankless systems typically last 20+ years—twice as long as conventional tanks
- Reduced Waste – Component-level repairs minimize environmental impact compared to whole-system replacement
- Lower Lifetime Cost – Despite higher initial investment, the extended lifespan and modular repair options result in lower total ownership costs
This sustainable approach to water heating aligns with modern environmental consciousness while providing superior long-term value for Atlanta homeowners.

Tankless Water Heater Frequently Asked Questions
Instead of storing water, tankless water heaters use heating coils to heat water as it’s needed, which is why they’re often referred to as “on-demand water heaters.” When you turn on a tap or start an appliance like a dishwasher, the tankless unit detects the demand and immediately begins delivering hot water where and when you need it. This makes tankless water heaters much more energy-efficient than traditional tank units, which continuously heat water even when it’s not in use.
Tankless water heaters offer several advantages over traditional tank units. One of the key benefits is an endless supply of hot water. You can run multiple showers, do laundry, and use the dishwasher at the same time, all while enjoying uninterrupted hot water.
Another significant advantage is nearly instant hot water—no more waiting for several minutes for the water to warm up; your tap will deliver hot water in seconds.
With a Rinnai tankless water heater, you’ll also save space, as it’s much smaller than a traditional tank, and reduce energy costs due to its superior efficiency.
Additionally, tankless units typically have about twice the lifespan of tanked water heaters. Overall, a tankless water heater outperforms a traditional tank water heater in almost every aspect.
Rinnai® is the market leading tankless water heater. Plumbing Express exclusively installs Rinnai because we believe they are the best.

When selecting the right size tankless water heater, several factors come into play, such as the number of people in your home or office and the number of facilities (like bathrooms, washrooms, laundry rooms, or kitchens) the unit will support. To make this process easier, our team can help you choose the ideal Rinnai tankless water heater capacity for your needs.
A Rinnai tankless water heater can last up to 20 years, with its actual lifespan depending on factors like water quality, usage, and regular maintenance. For comparison, a tankless water heater lasts roughly twice as long as a traditional tank water heater, offering better value over time.
Rinnai tankless water heaters run on natural gas or propane and feature an electronic ignition system.
Traditional tank water heaters are the most common type in the US. These heaters use older, less efficient technology to gradually heat cold water stored at the bottom of a large tank, constantly keeping the water heated until you need it. In contrast, tankless water heaters heat water on demand using heating coils, eliminating the need for storage. Tankless units are more energy-efficient, take up less space, and offer advanced technology not typically found in tank-based systems.

Daniel was first rate. Knowledgeable and courteous, he address all our concerns expertly. We were delighted that he able to replace our tankless water heater the same day, and it has been working great ever since.
Would definitely recommend a Plumbing Express! About a month ago, we had an issue with leaks and ended up needing a full home repipe. Ed was our first point of contact and was wonderful at explaining everything to us. He was very thorough and helpful, which made a stressful situation feel more manageable. Communication was consistent throughout the entire process, which we really appreciated. A couple of days later, the work began and we met Jose and his team for the repipe. Everyone was great and worked diligently from early morning to late evening, completing everything in just one day. The next day, Kenny and his brother came in to handle the drywall, and they did an amazing job. With all the holes that had been made during the repiping, you truly couldn’t tell where anything had been opened up. This was a 2 day process. Ivan was also a pleasure to work with and helped us with any questions and payments along the way. Pricing was fair for the amount of work done, especially considering how quickly and efficiently everything was completed. Overall, this process was overwhelming for us, but the entire Plumbing Express team made it so much easier to get through.
Our house is less than six years old, so a total house re-pipe was about the farthest thing from our minds. But a hot water PEX pipe failed under the slab in our bathroom in an area that would require the shower area and some of the bathroom to be destroyed in order to get to and fix the leak. Obviously not a good situation and in the final analysis, a total re-pipe of the house would cost less and then we wouldn't be wondering if/when another under-slab leak would occur. We end up selecting Plumbing Express to do our large job. They have a team that does nothing but repiping ... including the initial assessment, all the plumbing, and then all of the drywall repair. And they do the whole thing really well. Everyone (and I mean everyone) at Plumbing Express that we interacted with during this extensive project was great. Ty handled our first phone call and was helpful. Ed came to do the initial assessment and also helped later on in the process. He has extensive experience and has a great way of relating that background to your situation. Ivan was the project manger and he was always very responsive and helpful. Lucio (the lead plumber), Hose', Ben, and Rad were the four plumbers that did the plumbing work. They were experienced, respectful, pleasant, and clearly liked working together. Lucio even found a way to get repiped hot and cold water to our kitchen island without having to jackhammer the floor and slab. Kenny and his crew did the drywall repair (and there was a bunch of it to do) and painting. Ed and Ivan told us that after Kenny was done, we wouldn't know that the plumbers had even been here. We were very skeptical. Holes were everywhere in walls and ceilings. But Kenny and his crew did a fantastic job with all of the repairs and it all looks as good as before the project began. It is impressive how well they employed their skills. We had (and still have) a tankless water heater with a recirculating pump and system. Prior to the repipe, some of our outlets had hot water faster than afterward. That is a function of the fact that the piping under the slab could be more direct to areas than the repipe that had to go overhead and through the walls. To a certain degree, that is just the way it is. But Ed and Ivan went the extra mile to help mitigate that situation in one area by working with us on installing an under-sink small water heater in the kitchen. That helped tremendously for that area. Facing this major plumbing situation, especially in a relatively new house, obviously isn't fun in any way. But these guys made the whole process as seamless and pleasant as possible for us. They truly are professional, helpful, friendly, and skillful. Regardless of how old your house is, if you need to have a repiping job done, this is the team you want!
Dylan arrived on time and was polite. He repaired a burst pipe to exterior faucet and did a great job. He also cleared a bathroom drain, advised we not use drain cleaners and showed us the gadget he uses. We will definitely call on Plumbing Express again.
Plumbing Express had some sound advice and good recommendations for the situation that I was in. The technician was helpful and very understanding.
Replacement of garbage disposal done quickly and cleanly by Tim. On time, too. Wonderful experience!
I had a great experience with plumbing express. JOSH arrived early, listened to the problem I was having and provided excellent solutions. He definitely went above and beyond to make sure I was completely satisfied.
Josh was very knowledgeable and helpful with the repair, installation and setting up the Moen Flo app.
Just purchased a home that had polybutylene pipes throughout. Searched online to find a company who specialized in repiping. Came across Plumbing Express. Read the reviews and comparison shopped as any good consumer should. Plumbing Express stood out above the rest by far. Blake provide information and proof to back his product. The installers arrived BEFORE their appointment, took excellent care of my home, and the drywall repair was perfection. I am extremely pleased with my choice. You can't go wrong with Plumbing Express. Update 3/20/26 I have found my forever plumber. I had Plumbing Express repipe my home a few years ago. I recently reached out; because, I thought I had a plumbing issue developing. Fortunately, I did not. The service technician Dylan was outstanding. He calmed my and my husband concerns and provided a plethora of information. I no longer have to worry about finding a good plumber. Dylan will be my go to plumber every time.
I had a great experience with my plumber Tim Robinson today. He was fast and very knowledgeable. I will definitely recommend him to others.
These guys sure know what they are doing. Besides that they where efficient, friendly, and quick
Had a great experience with Dylan from Plumbing Express! Scheduling was a breeze, he showed up on time, and his knowledge was impressive — he addressed all of our concerns without hesitation. The repair price was very competitive, and he even threw in an extra service at no additional charge. Will definitely be calling Plumbing Express again!
Rod was friendly and knowledgeable. He was very professional and efficient. He provided me with repair options with pricing.
Rod did an awesome jobinstalling my tankless water heater!! His attention to detail during the installation and clean up was top tier!!! I am very impressed with the service and product.
Dylan provided excellent service from start to finish. I would definitely recommend Dylan for anybody that values and appreciates receiving top-notch service.
Rod Anderson did an excellent job of removing pipes and closing off water access to my former master bathroom. It's now ready to be converted to a master walk-in closet. He did three different jobs in a timely manner. He's also a very nice and pleasant person. I will request him to come for my future plumbing projects.
We had Tim Robinson come to our laundromat to fix an issue what was causing a back up when our white top loaders where running. We had another company out before them that couldn't do the descaling and stated we needed to tear up the new floor we just did so they could do a camera inspection that maybe there was an issue with the pipe. Tim came right in and did the camera inspection and was able to do the descaling, the pipe was clogged causing the issue. We had a busy weekend with the washers and no issues at all. Splish Splash Laundromat is so glad we went with Plumbing Express.
Daniel was wonderful and we are happy with the work he did replacing our disposal. We would recommend.
Tim was amazing with a problem that we thought was bigger than it was. Friendly, professional and knowledgeable. Will highly recommend you reach out for honest and fast service!
Tim Robinson was very thorough and professional. He provided me with information on the process for repairs, estimates, and options for slab leak.
Josh was professional, honest and personable. He diagnosed the problem and even after I had signed a more expensive estimate, when he found the problem could be solved for less he let me know. Fast, efficient, and extremely knowledgeable. Highly recommended.
2nd time using their services and they didn’t disappoint. Very professional and friendly
I woke up to no hot water Sunday morning! I called Plumbing Express and they were able to schedule me for first call Monday. Josh arrived and surveyed the situation. He advised me that the T &P line had not been attached by the person who originally installed this in 2022! Josh attached the T & P, drained the water heater and set up the app on my phone for this water heater. Because I had the app, I got an email Tuesday morning with a water sensor alarm - I called Plumbing Express & Josh came back out to check it out. Gratefully it turned out to be the residual water that drained out of his hose when he disconnected it from draining. I highly recommend Josh and the Plumbing Express team!
As we expected Dylan did a fantastic job!! Dylan kept us informed along the maintenance and repair. Answered all questions we had before we even asked. Outstanding service , we were so very pleased. Dylan is a top notch professional ❤️❤️☀️☀️☀️☀️
Very knowledgeable, professional and personable. Completed the work on my bathroom and left everything nice and clean.
Tim did an awesome and quick job clearing a drain. He gave me a competitive quote and was very personable as well.
Anthony was great! Thorough, professional, courteous. He spent a great deal of time listening, answering my questions, and educating me.
Ivan is a very good service tech! He has taken care of all of my issues in a timely manner! He is a great asset for your company! He took care of a water leak we had in a quick timely manner!
Extremely knowledgeable and very helpful. The team was excellent. The job was completed in 1 day with a great team. Very expressive.
2 other companies and plumbers couldn’t fix the issue but Dylan was able to identify and fix the issue in one afternoon.
Tim Robinson and his crew did an awesome job on my plumbing issues. Quickly diagnose my problem, gave an estimate for the repair in a timely fashion No surprises. I don’t normally like recommending contractors electricians plumbers, but Plumbing Express is top-notch on my list. They were very good about notifying me with updates when the crew was on the way and worked me in on an earlier date, then was originally scheduled for. Thank you, Plumbing Express! Keeping you in my contacts.
Rod was professional and courteous. Provided insight and detailed quotes regarding my issue. Highly recommend
I had a whole home repipe on my home. It was built in the 70s and the copper pipes were constantly springing leaks so it needed to be done. They quoted me a competitive price for the job, but the best part was the followup and communication with the team along the way to ensure my specifications were met and I was completely satisfied with my water system. Ed Torres the plumber along with Ivan the scheduler, and really the whe team that completed the work and the drywallers, couldn't recommend them enough.
The entire team was awesome. I had a repiping done. They were very courteous, efficient, and knowledgeable. I will definitely refer this company.
