Nicole Tukes

Water heater decided to call it quits after 22 years. Water pressure on hot side dropped to nothing and brown sediment started coming out of the hot side lines. Called Dalmation Plumbing first thing in the morning and they had Jim come out at 8:30am -- fast response. Jim replaced the water heater and expansion tank. In addition he also helped replace a leaking hose bibb and our water pressure regulator (PSI over 100). Jim was great and very knowledgeable. Would hire him again! Pricing was reasonable but on the higher side of the average range (based on Google Gemini cost comparison). But for an urgent service call and fast response, you can't ask for more! Will definitely use Dalmation Plumbing again in the future.

Fernando came to our home to check on a leak. He was so polite and kind! He was highly knowledgeable and resolved it in no time. We will be calling nobody else for all our future plumbing needs. 10/10 Highly Recommend!

Fernando did an amazing job on my sink repair. I had an issue with leaking and the housing of the faucet was weak and low pressure. The upgrade he did and install was professional and quick! His customer service is excellent and I would recommend this company and him personally hands down and I...

Gwendolyn Hooks

Recently purchased a home & started having issues with the water heater. Went through two other companies to take a look & both seemed unreliable with the information provided. My mom put us in contact with Simeon at Dalmatian who quickly got us scheduled with a tech for the next day. Gary was able to come out, take a look & tell us what was wrong & gave us multiple options to get the issue resolved. We decided on a new water heater. Installation was quick. The level of professionalism with this company is amazing. Will be using them for all of our plumbing needs moving forward.

Bklyn Crisci

We needed a new water heater and a neighbor had just used Dalmatian Plumbing and had been very pleased. I called them, Fadil showed up at at 1PM and before 3 we had a beautiful new water heater, then by 4 hot water! Fadil was great, addressed any concerns I had, a most pleasant and funny guy....

Reid Harris

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.

Christine Lascols

I called Dalmatian to install a manufacturer provided warranty kitchen faucet and to replace several shower cartridges that have been a long standing issue in our house and not fixed by other plumbers. Dalmatian lived up to their reviews and arrived on time and did a GREAT job. Houston was pleasant, worked with us to make sure they did what we needed and what was expected. Houston had to go get one part not on the truck and did so happily. He and Dalmatian will get our business going forward. It's nice to be able to trust a technician and a company. Well done, thanks!

Steve Kosmala

Pricing is fair and Fernando went above and beyond. We had a leak in our basement ceiling. It didn't take long for him to find the leak and repair it. I am surprised at how affordable the repairs were. Dalmatian Plumbing as a whole is excellent to work with. Simon, was very proactive with the...

Bill Groff

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.

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.
