Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, heat water precisely when you need it — eliminating the need for a storage tank. Unlike traditional tank systems that constantly heat and store water, these innovative units provide hot water only when needed, greatly improving energy efficiency.

As the leading plumbing expert serving the Greater San Antonio area — from bustling Downtown near the River Walk to the charming streets of Alamo Heights — George Plumbing Co., Inc. is here to transform your hot water experience. 

Discover how our state-of-the-art tankless solutions can elevate your comfort and efficiency. Contact us today.

Benefits of Tankless Water Heaters

The demand for energy-efficient water heaters continues to grow, and San Antonio’s hard water conditions make tankless installations a particularly smart investment.

These systems are celebrated for their innovative design and performance, even in areas with a high mineral content in the water supply. They offer benefits such as:

  • Energy efficiency
  • Endless hot water
  • Space-saving design
  • Longevity
  • Minimizing energy waste

Common Tankless Water Heater Problems

When dealing with hard water — a challenge common to the San Antonio area — it’s essential to collaborate with a knowledgeable plumbing professional for tankless water heater repair. Homeowners may encounter issues that require expert tankless water heater troubleshooting: 

  • Water temperature fluctuations: Caused by a variance in water pressure or mineral deposits, these can often be resolved through periodic system maintenance.
  • Inadequate hot water supply: This may stem from undersized units or scaling issues and is best addressed by proper system evaluation.
  • Mineral buildup: Over time, calcium and magnesium deposits can impair performance; routine descaling is the recommended solution.
  • System error codes or shut-offs: These alerts typically indicate sensor or control problems that require prompt professional diagnosis to restore optimal function.

Tankless Water Heater Installation

Our dedicated team proudly assists San Antonio residents in embracing the benefits of these advanced units through professional tankless water heater installation. Our process includes: 

  • Home assessment: Evaluating your space and plumbing needs to determine the best solution.
  • Tankless water heater sizing: Ensuring the unit fits your household’s demand for efficiency and performance.
  • Choosing between gas and electric models: Helping you select the option that aligns with your energy preferences and installation requirements.
  • Code-compliant, professional setup: Our installations adhere strictly to local codes, ensuring safe and efficient operation.

We emphasize precise sizing and safety protocols to guarantee that your new tankless system performs flawlessly in your home.

Tankless Water Heater Repair

Our repair services cover common issues associated with tankless units, including error code resolution, fixing ignition failures, and recalibrating water flow sensors.

We focus on restoring normal water heating performance with a quick, expert diagnosis designed to minimize downtime and inconvenience for tankless water heater troubleshooting.

Tankless Water Heater Replacement

While many clients choose to repair their systems, frequent maintenance and persistent issues may indicate that replacing your old tankless water heater is a more cost-effective solution.

  • Age (10–15 years): Over time, even the best systems can wear out.
  • Frequent repairs: Recurring problems might mean your unit is nearing the end of its lifespan.
  • Inability to meet household demand: If your system no longer supports your family’s needs, a new installation could be the answer.

Our streamlined replacement process involves carefully selecting the right unit, safely removing the outdated system, and installing a modern, high-performance model.

Abigail B.

I have been beyond impressed with the punctuality, honesty, knowledge, patience in explaining things, and superb professionalism of Kody and Patrick. I had a very complicated job, and their price was beyond fair. I had roots growing into my piping in 14 ft of foundation. It is truly a relief to work with a company and people that do a great job, price fairly, care, and go above and beyond.…

Robinette L.

Will and Austin listened to our concerns and provided us with options and pricing regarding repairing the current water heater or installing a new system. Their work was meticulous and detailed. They took time to provide an overview of our new system and all the work done. I was very impressed with their professionalism and excellent customer service! I strongly recommend George Plumbing for any plumbing concerns or needs.

Jared G.

Kody and Nathan were absolute professionals when they arrived, explained in layman’s terms the issue and provided an accurate estimate. Then they completed the work quickly and expertly giving us water pressure back when we needed it most. As a young family with an infant, water is pretty important and these two gentlemen are as good as it gets when it comes to professional plumbers.

Francesca K.

I called George Plumbing Co. on a Thursday and Doug and Nick came the next day. I had a clog in the line going from the back of my washer to the main part of my house. Additionally, small leaks were coming from the cut-off valve behind the washer. Doug and Nick were wonderful. The work done was exceptional.

Ed. T.

Kody and Nathan were very professional. Kody gave me several estimates. I decided on one and they went to work very quickly. Both gentlemen were knowledgeable, respectable, and very professional. You can also tell that they take pride in their work. I am very happy with their work. I will definitely Yell for George again.
