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The advanced electronic ignition system replaces outdated standing pilot lights, further reducing energy consumption and enhancing safety.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

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.
Called Plumbing Express as tankless hot water not operating. Their website states "Get Free Plumbing Quote ". When service man showed up an looked at unit he said there would be a $207 charge to look into unit in order to give me a quote to fix unit. Due to not having hot water and time required to get another company to address the problem I agreed to pay $207 for quote. After looking in unit I was told he would not be able to fix due to age of unit and parts not available. I think he should have said parts not available when seeing model number on front of unit and I would not have wasted $207.
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.
Daniel did a great job and was very professional during his service call last week!
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!
Tankless Water Heater Frequently Asked Questions
What is a tankless water heater?
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.
What are the benefits of a tankless water heater?
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.
Why choose Rinnai® for your tankless water heater?
Rinnai® is the market leading tankless water heater. Plumbing Express exclusively installs Rinnai because we believe they are the best.
Rinnai® is the registered trademark of Rinnai Corporation used under license by Rinnai America Corporation. All Rights Reserved.
What size tankless water heater do I need?
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.
How long does a Rinnai tankless water heater last?
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.
What types of fuel do Rinnai Tankless Water Heaters use?
Rinnai tankless water heaters run on natural gas or propane and feature an electronic ignition system.
Why does a tankless water heater cost more than a tank water heater?
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.
Can a tankless water heater produce enough hot water for my home?
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.
Can I change the hot water temperature on my Rinnai?
Yes. Rinnai tankless units can be controlled on the unit or by using a wifi mobile application.
Are there tax credits available if I purchase a Rinnai tankless water heater?
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.
Why choose Plumbing Express?
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.
Do you offer tankless water heater maintenance and repair?
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.
