Tankless Water Heater Installation & Repair in San Antonio, TX

Hot water is one of those modern luxuries you don’t really think about—until it’s gone. If you’re tired of running out of hot water halfway through a shower, dealing with bulky storage tanks, or paying high energy bills for heating water you’re not using, a tankless water heater could be the solution you’ve been looking for. At My Throne Plumbing, we specialize in professional tankless water heater installation and repair services throughout San Antonio, TX. Tankless systems, also called on-demand water heaters, provide hot water instantly whenever you need it — without the need for a storage tank. This not only saves space in your home or business but can also lower your energy costs significantly. Whether you’re switching from a traditional tank model, replacing an old tankless unit, or repairing an existing system, our licensed plumbers ensure the job is done correctly, efficiently, and in compliance with local plumbing codes. With us, you get reliable hot water, expert installation, and peace of mind.

Our Tankless Water Heater Installation Process

Installing a tankless water heater is more complex than swapping out an old tank. These advanced systems require precise sizing, gas or electrical upgrades, proper venting, and expert calibration to function at peak performance. At My Throne Plumbing, we follow a proven installation process to ensure your new system works flawlessly.

Benefits of a Tankless Water Heater

Switching to a tankless water heater offers numerous advantages for homeowners and businesses in San Antonio:

Endless Hot Water

On-demand systems heat water instantly, so you’ll never run out — even if multiple taps are running at once.

Energy Efficiency

No need to keep 40–50 gallons of water hot all day; tankless models only heat water when it’s needed.

Longer Lifespan

With proper maintenance, tankless water heaters can last up to 20 years, compared to the 8–12 years of traditional tanks.
