Enjoy endless hot water with tankless water heater installation from Holloway Plumbing. Serving Kerrville, Boerne, and Fredericksburg with trusted local expertise.

Go Tankless! Endless Comfort for You and Your Family

Imagine a world where you never run out of hot water, no matter how many showers are taken or how many loads of laundry are run. A world where you reclaim valuable closet space and lower your monthly energy bills. That’s the reality a tankless water heater offers. These modern, efficient systems heat water on demand, providing an endless supply while saving space and money.

Here in Texas Hill Country, making the switch to tankless is a smart investment in your home’s comfort and value. At Holloway Plumbing, our family has been helping our neighbors with their plumbing needs for nearly 50 years. We have the expertise to help you choose and install the perfect system for your Hill Country home.

Choosing the Right Tankless System

Unlike traditional tanks, tankless water heaters require careful sizing to match your home’s specific requirements. Our professionals can help guide you through the key considerations, including but not limited to the following:

  • Gas vs. Electric: Most whole-home systems are gas-powered for higher output, while smaller electric models can be great for a single sink or shower.
  • Flow Rate (GPM): Gallons Per Minute (GPM) is perhaps the most critical factor. We’ll calculate your home’s peak demand—how many hot water fixtures you might run at once—to select a unit that can keep up.
  • Temperature Rise: This is how much the heater must raise the water temperature from the ground to your desired setting. With our cool Hill Country groundwater, selecting a unit with sufficient temperature rise is crucial for consistent performance.
  • Recirculation: Want instant hot water at every tap? We can install models with built-in recirculation pumps that eliminate the wait, while helping conserve water.

While our experienced technicians can diagnose and service nearly any tankless model you might have, we specialize in supplying and professionally installing the industry’s top residential brands: Navien, Rheem, and Rinnai.

Our Code-Compliant Installation is Next Level

Tankless water heaters are sophisticated pieces of equipment, and their performance and safety depend almost entirely on the quality of the installation. You get yourself a bad tankless install job, and you’ll have poor performance for as long as you own it. Not to mention you’ll have one dangerous indoor appliance on your hands! Our licensed plumbers are meticulous with tankless water heater installations, ensuring every finished job meets or exceeds local codes. Our process includes but is not limited to the following:

  • Proper Venting: We ensure your unit has the correct intake and exhaust venting for safe and efficient operation.
  • Gas Line Sizing: Tankless heaters require more gas than tank models, so we often need to upsize the gas line to provide adequate fuel.
  • Condensate Drains: High-efficiency condensing models produce acidic condensation that must be properly drained and neutralized.
  • Water Treatment: Hard water is tough on any appliance. We can install scale mitigation systems to protect your investment and ensure longevity.
  • Isolation Valves: We install service ports and isolation valves that make future maintenance, like descaling, simple and clean.
  • Freeze Protection: For outdoor installations, we ensure the unit’s built-in freeze protection is correctly configured for Hill Country winters.
