Our Customers Say It Best

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.

Dalmatian Plumbing did a solid job installing my new gas line. Donald Land handled the work, and he was punctual, careful, and kept me updated as he went. The install was clean and the pricing was fair. I’d definitely use them again for future work.

Booker Young

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

They responded immediately to my request for service and had someone inu home the next day! Gary was extremely knowledgeable and patiently answered all of my questions. He provided the inspection that I needed to provide to my homeowners insurance to get my issue resolved thoroughly. I highly...

Margaret Winston

Our hot water heater was leaking and I called the guys at Dalmatian Plumbing and they had someone on the way to my house within 20 minutes. Chris was amazing. He was very clear on the explanation of the issue and pointed out issues in our existing setup that should not have passed home inspection. He came back out the next morning and was finished with the replacement in a few hours. Dalmatian will definitely be my first call for all plumbing related issues in the future.

Scott Shelton

It is difficult to think of a pleasant plumbing repair experience but that is exactly what Chris provide to my family. He kept us updated regarding his projected time of arrival and actually was always on time. Great knowledge, easy to work with, explains what he is doing, pleasant, well spoken and cleans up his work area. Reasonable price and well above average service. Dalmatian Plumbing is the only company I will use and recommend going forward.

Bernie Breton

Christian was prompt and quickly assessed the situation. He explained to me what the job entailed and the price breakdown. When additional work was needed, he gave me a discount which I appreciated. He was very respectful and patient to answer all my questions. I was very happy with the service.

J. Mendoza

I had Jason from Dalmatian fix a dripping bathroom shower head. He arrived when he said he would and covered his feet with booties which my wife much appreciated. He then gave me a fair price estimate and immediately got to work. Unfortunately, the part needing to be replaced was not easily found but over 4 days he stayed in contact and was quick to call, say the part was in and came immediately to replace it. I really appreciated his diligence in hunting down the part and his keeping me up to date during the search. He has a pleasant, calm. reassuring, confident attitude and the skills to do the job. I have a couple of plumbers I could have called but glad I gave Dalmatian and Jason a chance. If further problems will certainly call them again.

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.
