Tired of These Common Water Heater Frustrations?

If any of this sounds familiar, you're in the right place. Total Tankless specializes exclusively in solving these exact problems.

Running Out of Hot Water

Waiting 30 to 60 minutes for your tank water heater to recover after a long shower is inconvenient and frustrating.

High Energy Bills

Traditional tank heaters constantly reheat water 24/7, even when you're at work or asleep. Tankless units only heat water on demand.

Finding a Trusted Specialist

Most plumbers specialize in tanks. You need someone who installs and services tankless systems every day, not someone learning on your home.

Confused by Brands & Sizing

Rinnai vs. Navien vs. Rheem? GPM vs. BTU? Sizing a tankless system correctly matters, and the wrong choice leads to lukewarm showers.

Unsure About Upfront Cost

Tankless costs more upfront than tank replacement, but lasts twice as long. Understanding the real value helps you make a confident decision.

Uncertain About the Process

What does installation involve? Do you need permits? How long does it take? Getting straightforward answers upfront removes the guesswork.

What Homeowners Say About Their Tankless Water Heater Experience

"Total Tankless made our upgrade from a 15-year-old tank heater completely painless. The virtual estimate was spot-on, and the local plumber they connected us with was professional and thorough. Endless hot water is life-changing."

Michael R. — Tampa, FL

"Our Rinnai started throwing error codes and we had no idea what was wrong. Total Tankless had a repair tech at our house the next day. He diagnosed the issue in minutes and had us back up and running. Great service."

Jennifer L. — Houston, TX

"I appreciate that they don't push you to buy. They answered all my questions about sizing and brands, gave me a free estimate, and let me decide on my own timeline. When I was ready, the installation was seamless."

Frequently Asked Questions

How much does a tankless water heater installation cost?
Most homeowners invest between $5,000 and $9,000 for a whole-home gas tankless water heater, fully installed. If you're replacing an existing tankless unit, the cost typically runs $3,000 to $5,500 since the gas line, venting, and mounting infrastructure are already in place. Factors like your current water heater type, gas vs electric setup, home size, and unit accessibility all affect the final price. We provide free virtual estimates so you know exactly what to expect.
What brands of tankless water heaters do you install and service?
We work with all major tankless water heater brands including Rinnai, Navien, Noritz, Rheem, Bosch, and AO Smith/Takagi. Our vetted local plumbing partners are trained to install, repair, and maintain units from every leading manufacturer, so you get expert service regardless of the brand you choose.
How long does a tankless water heater installation take?
A straightforward tankless-to-tankless replacement typically takes 3 to 5 hours. A first-time conversion from a traditional tank water heater usually takes a full day, as it may involve gas line upgrades, new venting installation, and electrical work. Our plumber will give you a precise timeline during your free estimate.
What are the benefits of switching to a tankless water heater?
The primary benefit is continuous, on-demand hot water that never runs out. Tankless units also take up significantly less space than traditional tank heaters, last 20+ years with proper maintenance (compared to 8-12 for tanks), and operate more efficiently since they only heat water when you need it. While the upfront investment is higher, homeowners who plan to stay in their home for 3+ years typically find tankless to be the better long-term choice.
Do you provide tankless water heater service in my area?
Total Tankless currently serves major metropolitan areas in Florida (Tampa, Orlando, Fort Lauderdale, Jacksonville), Texas (Houston, Austin), Colorado (Denver), and California (Inland Empire, San Jose). We're actively expanding to new markets. Call us at 833-350-5930 or request a free virtual estimate to confirm availability in your area.
