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The advanced electronic ignition system replaces outdated standing pilot lights, further reducing energy consumption and enhancing safety.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.

Yes, there are Federal Tax Credits available. If you select a tankless gas water heater, hybrid gas water heater, or natural gas tankless water heater with an energy factor of at least 0.82 or a thermal efficiency of 90% or higher, you may qualify for these tax credits.
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.

Daniel was amazing! He represented the company to the very best standards! I will dwfinitely use him again! Very Professional! Courtesy! A very positive experience! Will use in the future! Absolutely
This was my second time using Plumbing Express. Once again, I had an excellent experience with Dylan
Anthony came to my house for an ongoing problem of extremely high water bills. He quickly diagnosed and fixed the issue. Anthony has a pleasant attitude and provided great service with professionalism and care for my home and property.
Everything about my experience was A++ service. From the friendly receptionist who took our call and let us know available times to Dylan who was friendly, knowledgeable and extremely professional. He helped fix everything and left it better than ever. Great Atlanta plumber team. You will not be disappointed!
My issue was a water heater being a great distance from my kitchen sink causing water waste as I waited for hot water to reach the kitchen. Daniel was very familiar with the issue. In a very brief time, he installed a recirculating pump on my water heater and a sensor valve at my sink. I now have instant hot water where I need it. Express plumbing was very responsive to my call, arrived promptly, and Daniel did an exceptional installation job. Express Plumbing can be proud to have an employee like Daniel representing them.
Very nice experience working with Plumbing Express, particularly with Tim Robinson who complete the job as expected. He listened and understood my concerns and try to address them as close as possible. Very nice work. Thanks guys.
Rod was courteous and focused. He had the situation sized up and solved by the time I got out to the meter-box to greet him. I was impressed with his talent for deduction and followed his train of thought in trouble shooting the problem. There was no leak after the watermeter and the watermeter worked fine. The evidence was subtle but it was there. Water wasn't leaking out of the box it was leaking in by the direction of the mud residue build-up. Thanks again Rod!
We had water pressure and water temperature issues, which turned out to be caused by a failing pressure regulator valve and a failed valve in a crossover recirculator. Anthony diagnosed and replaced both, repaired a pinhole leak in a copper pipe near the PRV, and did the annual service on our tankless heater, all in less than 3 1/2 hours including a 45 minute trip to pick up the correct PRV for our system. He is always fast, efficient and knowledgeable, and willing to answer all our questions.
Daniel did a great job with the tankless installation, educating us on the new unit, and was very professional. Happy to have hot water once again. Thank you.
Rob came in and was friendly and completed the toilet repair quickly and professionally.
Fantastic, trustworthy and reliable Plumber. Highly recommend. Daniel was awesome. Hard to recommend any other plumbing business in Atlanta! These guys are honest and don’t nickel and dime you for everything.
We had a pool of water forming in our front yard, so we scheduled an appointment with Plumbing Express and they quickly sent Daniel to come diagnose the issue. When he arrived, he let me know what the potential issues were and gave me a very detailed breakdown of the costs and work involved, from best to worst case scenario. He was able to break things down in a way that I could easily understand, and I could tell that he was being honest with me which gave me the confidence to hire him to work on the issue. He quickly found the leak, showed me, and I immediately agreed to have him fix the pipe. Within an hour or so he had the leak fixed and filled the area he had to dig up, all while it was so cold it actually began to snow a little bit. I could not ask for better service and will happily go with Plumbing Express in the future for any plumbing needs.
Rod was very professional, courteous, and quick. I've also used Plumbing Express in the past and was happy with the service.
Tim was great. Took the time to explain what he was doing and break down everything that needed to be done.
I requested Dylan because he had previously came to our house to diagnose what was wrong with our Renni tankless water heater. He always explains what is wrong and what needs to be done to fix what's wrong. Dylan this a highly talented plumber.
They say, “you won’t know what someone is made of until you see them navigate problems and mistakes.” The install team were incredibly professional and courteous. They did unfortunately have a couple of big missteps, but they and their boss Ty handled it the way great companies do. They listened apologetically and made it right!! Ty acted honorably to make things right and Lucio, Joe, Ben and Rad did a tremendous job replumbing the house in just one day to bypass the leak under the slab. Grateful for their hard work and will certainly recommend to my friends and family!
Daniel did a great job of telling me exactly what the issues were as well as the solutions. He finished the work in a timely fashion and was able to recommend another company for possible water damage.
Polite, customer friendly. Both were very nice. Work completed on time and did what they said. Thanks, Harry Fraley
Anthony hooked up a firepit to a new gas line. He did a good job and worked quickly. He was friendly and explained things well.
Service is prompt and expert. Highly recommend. Mr Robinson minimized any disruption possible from installation. His professionalism and attention to detail is outstanding.
Third time using them, very positive experience, friendly, efficient and do clean work. Will call them again.
Very calm, respectful, and explained things well to someone who doesn’t know much about plumbing.
Anthony was amazing to work with. Very knowledgeable, friendly, and very quick to respond to our situation! We would recommend him to anyone.
I am very pleased with their work. Were the most affordable and they a terrific job. I highly recommend it
Anthony was very competent, professional and friendly. He answered all my questions throughly. Highly recommend!
Thanks to Rod Anderson. I had a great experience with the Mr. Anderson who came to my home. He was very professional, respectful, and honest. You could tell he really knew his work and took the time to explain everything clearly. I truly appreciated his knowledge and transparency. I would highly recommend his services and will definitely call him again if I ever need plumbing help!
After suffering a second leak under our slab and getting quotes from various plumbers, we decided to have our house repiped through the attic. Ed came by from Plumbing Express and I was convinced that they were the right company. Not only was their bid competitive with the other plumbers, but they also provided better insulation for the pipes and turnkey drywall repair and paint. The plumbing crew were polite and professional and kept the work areas clean. They kept the damage and the dust down to a minimum which was a pleasant surprise. After they completed the job, Flaniel repaired and painted the walls like new with no signs of patching. He was super clean and even mopped the floors before he left. I also want to give a shout out to Ivan in the office who orchestrated everything. Finally, I can say without a doubt, that if you have plumbing issues, Plumbing Express is the one to call.
Anthony is very professional and polite. He installed plumbing during reno for the master bath, basement bath and new kitchenette. Highly recommend.
Rod did a great job.He was very professional and informative. Great customer service overall.
Very happy with the pipe replacement. The whole team was super professional, knowledgeable, efficient and communicative
Installed new water heaters and a whole home water filter system. Great communication. Did everything they said they would do in the timeframe stated. Left everything clean and answered all my questions.
I had an outstanding experience with Rod. He was professional, punctual, and extremely knowledgeable. He quickly diagnosed the problem, explained everything clearly, and completed the work efficiently. The quality of his work was excellent, and he left everything clean and neat when he finished.
Smooth process from receiving the initial estimate to completion of our complete home repiping.
Rod Anderson was my technician. He was courteous, prompt, and knowledgeable. He was able to fi n d the problem and recommended next steps. Thanks for your services.
Had a leaking pipe around the hot water heater and another one showing alot of corrosion from calcium buildup. I needed these pipes repaired before they become a bigger problem. I have used Plumbing Express in the past and had great results so I called them again and got great results from their service on repairing these pipes and quick and efficient service. Dylan was great and very efficient and knowledgeable about what repairs needed to be done. I will definitely use Plumbing Express and ask for Dylan when I have any plumbing problems in the future!
