Our Customers Say It Best

Excellent experience from start to finish. They were professional, responsive, and transparent throughout the process. I needed to replace an older leaking water heater, and they took the time to evaluate everything on site, explain my options clearly, and answer all of my questions. I was out of town while trying to coordinate the project, and they were very accommodating with scheduling. They worked with my timeline and fit the installation in between two trips, which I really appreciated. The installation, done by Jim, was smooth and very well done. He upgraded me to a 50-gallon Bradford White unit at the same quoted price, installed a new expansion tank, shutoff valve, and pan, and handled the permit process as well. The workmanship was clean and professional, and the final result looks great. I also appreciated how respectful and easy to work with they were throughout the whole job. Highly recommend if you’re looking for honest, knowledgeable plumbers who do quality work and provide excellent customer service.

I am ELATED with Dalmatian Plumbing and with my onsite Professional Plumber, Jim. I called around 8am this morning and received a text round 9:26am confirming my person was in the way. Jim was friendly, courteous and used shoe covers inside my home. He listened tentatively, asked engaging questions to help identify the problem and a plan. I was impressed he took a holistic approach not just about my leak, but details of its impact on the house water system. He confirmed the plan, gave me the cost breakdown, and after approval, initiated the work. He engaged me as needed in the process with updates and patient with my elementary questions. I am so happy with Jim’s work, solving my leaks and organized the chaos of plumbing lines. Thanks to my Plumber Whisper, Jim.

Jim(Technician) was awesome. Thoroughly explained the diagnosis and steps needed. After completing the repair Jim was able to explain the root cause of the issue. Review Below: Timeliness: Showed up within 5 minutes of quotes time. Efficiency: Drywall was only removed where necessary to make the repair. Kudos to Jim's experience here! Price: Who is ever happy with what it cost to get something fixed? But to be honest, I'm happy and see the value in the spend. Value: Explained the root cause of the issue and provided the solution in a timely manner with a friendly disposition. Will be utilizing Dalmation for my future plumbing needs.

My service person was Chris Hank. He was very knowledgeable and great personality. Money well spent; I highly recommend this company. Before I finished typing this review he actually came back and took the trash that another company left behind.

Simone McDonald

I recently hired Dalmatian Plumbing for some repair work, and I’m very satisfied with the overall experience. They were professional, arrived on time, and quickly diagnosed the issue. The work was completed efficiently and with great attention to detail, and everything has been working perfectly since. What stood out most was their clear communication—they explained the problem, walked me through the solution, and made sure I was comfortable with the approach before starting. The pricing was fair and transparent, with no surprises. Overall, it was a smooth, stress-free experience, and I would definitely recommend Dalmatian Plumbing to anyone in need of reliable plumbing work.

Ray Rehal

We had a main sewer line stoppage and needed help fast, and Dalmatian Plumbing absolutely delivered. They came out immediately, which was a huge relief given how urgent the situation was. The job involved clearing the blockage through the water closet, pulling and resetting the toilet, and running a sewer camera to fully diagnose the issue. Everything was handled efficiently and with real professionalism. They took the time to explain what was going on, showed us the camera results, and made sure the problem was completely resolved before wrapping up. What really stood out was their attention to detail and respect for our home. The toilet was reinstalled perfectly, everything was left clean, and there were no shortcuts taken. On top of that, their pricing was very fair for the amount of work involved, which made the whole experience even better. If you’re dealing with a tough plumbing issue and want someone reliable, knowledgeable, responsive, and reasonably priced, I highly recommend Dalmatian Plumbing. Great service from start to finish.

Terri Blanchard

I am thoroughly impressed with the exceptional service provided by Jason Minor, who installed our under-sink water filter. His work was professional, meticulous and neat, reflecting his high level of expertise. Jason's friendly demeanor and extensive knowledge made the entire experience pleasant and stress-free. He ensured that the installation was completed to our satisfaction. I am more than happy to recommend Jason and Dalmatian Plumbing for their outstanding service. If you're looking for a reliable and skilled plumber, I highly recommend reaching out to them.

How Tankless Water Heaters Work

A traditional tank water heater keeps 40-80 gallons of water hot around the clock, burning energy even when no one's home. A tankless water heater eliminates the tank entirely. Cold water flows through the unit, and a high-powered heat exchanger heats it in seconds, delivering hot water on demand for as long as you need it.

The result: no stored water to run out, no standby heat loss, and a unit roughly the size of a suitcase that can mount on a wall and free up significant floor space.

Understanding How Tankless Water Heaters Operate

Tankless water heaters, often called on-demand systems, heat water only when it's needed instead of storing it in a tank. When you turn on a hot water tap, cold water runs through the unit, where a gas burner or electric heating element quickly warms it. This process delivers a steady flow of hot water for as long as you need it, unlike traditional tank models that can run out.

Because they don't have to maintain a large tank of hot water around the clock, tankless systems are more energy-efficient and can help lower utility costs. Homeowners often find them especially useful for households with higher hot water demands or for those looking to save space, since these units are compact and wall-mounted.

Gas vs. Electric Tankless Water Heaters: Which Is Right for Your Atlanta Home?

This is the question most homeowners have first, and the answer depends on several factors specific to your home and usage.

Gas tankless water heaters

Most common choice for Atlanta homes with existing natural gas
Heat water faster than electric models
Handle higher simultaneous demand (multiple showers, laundry, dishwasher running at once)
Typically have lower monthly operating costs
Installation usually requires a dedicated gas line and proper venting

Electric tankless water heaters

Well-suited for point-of-use applications
Electric units can perform well for smaller households without the same heating burden you'd see in colder climates
Larger homes with high simultaneous hot water demand are generally better served by gas.

Benefits of Going Tankless

Endless Hot Water Supply

Unlike traditional water heaters, which can run out of hot water, tankless water heaters provide a continuous supply of hot water on demand, ensuring that you will never experience cold showers again.

Energy Efficiency

Tankless water heaters only heat water when needed, reducing energy waste and lowering utility bills. This on-demand heating can result in significant energy savings compared to traditional water heaters, which constantly keep a tank of water hot.

Space-Saving Design

Without needing a large storage tank, tankless water heaters are compact and can be installed in various locations, freeing up valuable space in your home.

Longer Lifespan

Tankless water heaters generally last longer than traditional models, with a lifespan of up to 20 years or more. This durability makes them a wise long-term investment for homeowners.

Reduced Risk of Water Damage

Since no tank can leak or rupture, the risk of water damage from a tankless system is significantly lower, offering peace of mind and potentially lowering home insurance costs.

Federal tax credit eligibility

Energy-efficient tankless water heaters may qualify for a federal tax credit. Ask our team about currently eligible models when you schedule your estimate.

Signs Your Water Heater Needs Repair or Replacement

Whether you have an aging tank unit or a tankless system showing problems, these are the signals to call a plumber:

You're running out of hot water before everyone's showered
Your tank-style water heater is 10-15 years old (or older)
Your tankless unit is throwing error codes or failing to ignite
Hot water takes unusually long to arrive at fixtures
You're seeing rust-colored or discolored water from hot taps

If your current unit is 10+ years old and repairs are becoming more frequent, a replacement is almost always the more cost-effective path forward. Our technicians will give you an honest assessment either way.

Frequently Asked Questions

Q What are the signs that my water heater needs repair or replacement?

There are several indicators that your water heater may need attention. Look out for rusty or discolored water, strange noises coming from the tank, a lack of hot water, or water leaking around the unit. If you notice any of these signs, it's best to contact a professional plumber to assess the situation.

Q How long do water heaters typically last?

The lifespan of a water heater can vary depending on the type of unit and maintenance. On average, traditional tank-style water heaters last around 8 to 12 years, while tankless water heaters can last up to 20 years. Regular maintenance and timely repairs can extend the life of your water heater.

Q Should I repair or replace my water heater?

The decision to repair or replace your water heater depends on the extent of the problem, the age of the unit, and the cost of repairs compared to a new installation. A professional plumber can evaluate the condition of your water heater and provide expert advice on the most cost-effective solution.

Q How can I maintain my water heater?

Regular maintenance is crucial to keep your water heater running efficiently. Flushing the tank annually to remove sediment buildup, checking the pressure relief valve, and inspecting the anode rod are some common maintenance tasks. It's also advisable to have a professional plumber perform a thorough inspection and maintenance service periodically.
