Our Comprehensive Tankless Water Heater Services
A tankless water heater is a significant investment in your home's comfort and efficiency. Proper service from a qualified professional is essential to protect that investment. We offer a full suite of services tailored to the needs of Cibolo residents.
Professional Tankless Water Heater Installation
Whether you're building a new home, renovating, or finally replacing an old, inefficient tank heater, a professional installation is the key to performance and longevity. Our process is thorough and customer-focused. We assess your home’s specific needs, including family size, plumbing configuration, and typical hot water usage, to recommend the perfectly sized unit. Our technicians handle every aspect of the installation, from safely disconnecting and removing your old unit to making precise gas or electrical connections and ensuring proper venting for a safe, code-compliant setup.
Expert Tankless Water Heater Repair
While tankless water heaters are known for their reliability, they can occasionally experience issues. If you notice fluctuating water temperatures, strange noises, an error code on the display, or a complete loss of hot water, our skilled technicians are ready to help. We have the diagnostic tools and expertise to quickly identify the root cause of the problem—be it a mineral buildup, an ignition failure, or a faulty sensor—and perform the necessary repairs to restore your system to perfect working order.
Essential Tankless Water Heater Maintenance
To ensure your tankless unit operates at peak efficiency and reaches its full lifespan of 20 years or more, annual maintenance is crucial. The hard water common in the Cibolo area can lead to mineral and scale buildup inside the heat exchanger, forcing the unit to work harder and reducing its efficiency. Our maintenance service includes a comprehensive system flush and descaling, which removes these harmful deposits. We also inspect all components, clean filters, and check for any potential issues, preventing unexpected breakdowns and ensuring you get the most value from your system.

Understanding the Benefits of a Tankless System
Upgrading to a tankless water heater offers a range of advantages over traditional storage tank models, making it a smart choice for modern households.
- Endless Hot Water: Since water is heated on demand, you never have to worry about the tank running empty. You can enjoy long showers and run multiple appliances without interruption.
- Superior Energy Efficiency: By eliminating the need to constantly heat a large tank of water, tankless systems can reduce water heating energy consumption by 24% to 34%, leading to significant savings on your utility bills.
- Longer Lifespan: A well-maintained tankless water heater can last 20 years or more, often twice as long as a conventional tank heater, which typically needs replacement every 8 to 12 years.
- Space-Saving Design: These compact, wall-mounted units can free up an entire closet's worth of space, giving you more room for storage or other uses.
Choosing the Right Fuel Type: Gas vs. Electric
Tankless water heaters are available in both natural gas and electric models. The best choice for your Cibolo home depends on your existing utilities, budget, and hot water demand.
- Natural Gas Tankless Water Heaters: These are the most powerful option, capable of producing a higher flow rate of hot water. This makes them ideal for larger families or homes with high simultaneous hot water demands. While the initial unit cost may be higher, their operational efficiency can lead to greater long-term savings, especially for households already using natural gas. They require professional installation with proper ventilation to the outdoors.
- Electric Tankless Water Heaters: Electric models are often more affordable upfront and have a simpler installation process as they do not require venting. They are highly efficient but typically provide a lower flow rate than gas models, making them a good fit for smaller homes, apartments, or as point-of-use heaters for a specific sink or bathroom. It's important to note that larger whole-home electric units may require a dedicated, high-amperage circuit and a professional assessment of your home's electrical panel.
Answers to Your Common Tankless Water Heater Questions
What size tankless water heater do I need for my home?
Sizing is crucial and depends on two factors: the flow rate (how many gallons per minute you need at one time) and the required temperature rise (the difference between the cold groundwater temperature and your desired hot water temperature). A professional technician will calculate your peak demand to ensure your unit can handle your household's needs without compromising performance.
How often should a tankless water heater be flushed?
We recommend a professional flush and descaling service at least once a year. For homes in areas with particularly hard water, more frequent service may be beneficial to prevent efficiency loss and component damage.
Can I replace my old 75-gallon tank heater with a tankless model?
Absolutely. A properly sized tankless water heater can easily meet and exceed the performance of a large tank heater. It will provide more hot water overall (an endless supply, in fact) while using less energy and taking up significantly less space.
What are the signs my tankless water heater needs a repair?
Common signs include inconsistent hot water, a sudden drop in water pressure, unusual banging or rumbling sounds, visible leaks, or a diagnostic error code appearing on the unit's digital display. If you notice any of these symptoms, it's best to seek professional service promptly.
