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The advanced electronic ignition system replaces outdated standing pilot lights, further reducing energy consumption and enhancing safety.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.
Yes. No matter how large your home, we can configure a tankless system to meet your needs. Rinnai systems can meet the needs of every thing from a tiny house to a mansion. A Rinnai Tankless Water Heater solves the tank heater water inconsistency problem because hot water becomes delivered at a precise temperature to every fixture. Imagine providing unlimited hot water to your home.

Plumbing Express has the highest level of Rinnai dealer status and receives training at the Rinnai Headquarters in Peachtree City, GA. We provide quality service at a fair price.
Yes! In addition to our tankless water heater installation and upgrades, we offer maintenance and repair services. One of the many benefits of a tankless water heater is that components can be easily exchanged, if needed, versus replacing the entire system.

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.
Service couldn’t be completed due to needing a new system. We appreciate the very informative visit as well as insight that could help after a new unit install.
Plumbing Express was great. I had a failed sump pump that had partially overflowed into the basement. Nasty. Josh was the tech that did the work. He was efficient, neat and courteous. I will use Plumbing Express if I have any other plumbing needs and I will recommend them to my family and friends.
The technician was very knowledgeable and professional. I believe they did a very good job.
Ron was our second plumber from this company. The first plumber came, examined pipes and said he found no leak, even though we had experiences a large amount of water leaking from the ceiling in the finished basement. Several days later we had another leak-same area but less water the second time. Ron came in, listened to our frustration and did a more thorough inspection of the pipes and identified the problem. He was very personable and professional. On his third visit, we had several replacement pipes installed and are without leaks again. Our frustration, with the situation, was my son had used your company to replace pipes when he purchased the home and founding out not all the pipes were included with that process.
Tim arrived on time and was very professional. He took his time to explain the problem and the process it would take fix the water line.
Outstanding customer service, we will definitely be using them in the future for any plumbing needs. Can’t thank them enough!
Extremely knowledgeable and very helpful. The team was excellent. The job was completed in 1 day with a great team. Very expressive.
Daniel Perez was great in coming out to check the problem I had with a water leak from my air conditioner line. His recommendation was correct.
Great and informative service while I was in a bind without a functioning water heater.
Plumbing Express is my go-to plumbing support team. They have fair pricing, well-vetted technicians, and a truly exceptional scheduling system. Rod, my technician, was the best. He quickly assessed the problem and gave a fair estimate, working hard to keep to the schedule. He even brought Josh along on the day of service, and the two of them worked well together. They addressed the bathtub drain repair with expertise and caused the least sheetrock damage. It was difficult to replace the broken pipe and get to the upstairs drain, but together they made it a success.
Rod and Josh did an awesome job taking care of my clogged sinks. Knowledgable, professional and great to work with - I really appreciated their help today and would highly recommend them and Plumbing Express!
Daniel was excellent. The work he did was simply superb. I highly recommend your company and hopefully Daniel will get more and more work
Dylan from Plumbing Express came over and replaced our garbage disposal for us. It was older, had a massive leak, and needed to be replaced. He did a great job and was in and out in about 30 minutes! I also asked him to check out a potential leak I had been hearing in my ceiling. He used a thermal camera to investigate and was very honest and upfront about what he found. Rather than immediately cutting into the drywall to confirm something uncertain, he explained that the sound could simply be pipes expanding and that opening the wall might be unnecessary. He recommended monitoring the area and waiting to see if a wet spot appears, which would clearly indicate an actual leak. I really appreciated that he didn’t try to upsell or push unnecessary work. Overall, great service and a great guy. They will definitely be our go-to plumbing service from now on.
Once again we had some problems under our kitchen sink so we called Plumbing Express who were able to get us on their schedule pretty quickly after these storms Tim Robinson came out to do the job. Tim has been to our house for a number of different plumbing problems. He is personable & professional. As usual he did a great job even though this particular problem turned out to be far more difficult than anyone had expected. As frustrating as it was, Tim worked through it until he finished the job. We can't thank him enough.
Anthony was very competent, professional and friendly. He answered all my questions throughly. Highly recommend!
Anthony has come to my house a few times and he is always very professional, respectful of me and my home. He is also very knowledgeable in his craft.
TOTAL HOME RE-PLUMB. Our neighborhood has had so many homes experiencing water leaks (hundreds) that many of us have chosen to re-plumb before it happens. Based on my own experience speaking with four different plumbing companies, and speaking with several of our neighbors, I decided on Plumbing Express. They are knowledgeable, professional and very responsive to any questions along the way. Their price was fair and it’s one price for the whole job. You won’t have to find someone to repair and paint drywall. They have their own people or contractors to do that so your house looks perfect when they finish. I would highly recommend Plumbing Express to anyone needing to have their house re-plumbed. EDIT: Ed was the initial person I spoke to. His experience, knowledge and easygoing (non-salesman like) demeanor was greatly appreciated. Ivan was my point of contact for any questions and he was friendly and as I said, very responsive. He also installed a Moen smart valve in our home. Dylan plumbed the exterior of our home to the street while another crew did the interior re-plumbing. I’m very pleased with all of them.
Dylan did a great job fixing our Rinnai hybrid water heater. He didn’t try to do the typical “oh it’s over 5 years old you need a new one” that so many companies do. We really appreciated that! He did need to order parts, but they came in quickly and he was very efficient.
We had an excellent experience with Plumbing Express. They repiped my entire home and also handled all of the drywall repair and repainting afterward. When they were finished, it honestly looked like they had never been there—everything was spotless and perfectly restored. Ed Torres, the estimator, was wonderful to work with: extremely knowledgeable, professional, and thorough in explaining the process. Ivan Del Campo was my office contact, and he was fantastic at keeping me informed every step of the way, which I really appreciated. The team of four plumbers who removed the old piping and completed the actual repipe did an outstanding job. They were professional, hardworking, and efficient, and it was clear they took pride in their work. They answered questions when needed and were respectful of my home throughout the entire process. Kenny and Waldy, did a great job on the painting and drywall. They took a house that looked like swiss cheese and now you'd never know! From start to finish, the entire team was professional, communicative, and detail-oriented. I highly recommend Plumbing Express to anyone needing major plumbing work done right. It's not fun money to spend, but if you're in need-these are the guys to call.
Daniel was very professional and transparent. Also, this is the second time he has been to my home to repair a plumbing issue and his quality of work is A plus. GOOD JOB!
Dylan did a great job. He was very professional and courteous. Would highly recommend their services.
I would recommend Plumbing Express to anyone for repiping services. I got initial quotes from 4 different plumbers for replacing PB pipe, and Ed was by far the most knowledgable, informative, and personable that I interacted with. Price was also hard to beat, especially considering the drywall repair was included. The crews that came out to work were on-time and worked quickly. The drywall repair was seamless; as many others have said, it is impossible to know there were ever any holes in the walls. Throughout the entire process, Ivan stayed in contact and communicated proactively and clearly. Any issues or concerns we had were addressed promptly. The only complaint we had was that some of the workers didn’t clean up thoroughly after themselves and left behind debris/trash. One piece left was a metal piece from a pipe that could’ve damaged our lawnmower if it hadn’t been found. In general though, the work spaces were left clean. Overall, we’re very happy with the quality of work done and customer service experience. These guys know what they’re doing.
It was an easy and professional service. Execution and customer service is really really good. Anytime again. 5 stars if prices would be a bit cheaper.
Many thanks to Dylan for all of the work he put in yesterday to replace my hot water heater. It was an absolute pleasure to meet such a kind man who completed such a laborious task in such a short timeline, both skillfully and efficiently. Great communication all around, from the office updates on arrival timelines to expected finish time. Will absolutely recommend you in the future. Thanks again for your hard work! Happy New Year!
Tim and his crew did great work in replacing a water line at my home. They attended promptly, completed all work on time and cleaned up fully. Highly recommend Tim for any plumbing work.
This company is great - super easy to schedule, get in touch with them, good availability. Rod and Daniel are awesome and have been to our house multiple times and go above and beyond for us!!!! Cannot recommend this company more!!
Rod made a quick adjustment to our toilet system and explained how it all worked. Took just a few minutes. He’s a great guy, too
Rod came same day within 30 minutes of my call for no hot water. He checked both my tanks and got pilot light back on and flaring. He explained a lot about my units and left me quotes. If needed in future. He was very knowledgeable and professional. Thank you
Dylan was so kind. Our water heater had a leak that caused some damage and he came out today to assess and give us a quote for replacement. He was very professional and knowledgeable.
Rod came to our house today to sort out an issue. He was so awesome, he smiles, he has the best manners, he’s do kind and polite and was so efficient. Love this service so much
After finding out that my home of 21 years had a leak in the slab, I discovered that the slab was full of polybutylene and I would need my entire home repiped. I spoke with three different plumbers before discovering Plumbing Express. Ivan came to my home right away and thoroughly explained the process and the cost. He answered all my questions and it was an easy choice to choose this company. The crew (Lucio, Ben, Jose and Rad) arrived on time and got the repiping done in one day. They were pleasant and did a great job. The next two days, Flaniel arrived to do the dry wall and painting. Like the crew the day before, furniture and carpet was covered to protect my home. He was meticulous and did his job like an expert. He went over and above expectations. This company has its act together ! They are not pulling subcontractors but are using their own w-2 well-trained employees. What a difference this makes!
Tim Robinson did a fantastic job for installing upgrades for my kitchen sink, shower kit and bathroom faucets and pivoted to fix an unforeseen issue that came up which he resolved
