Tankless Water Heater Installation & Repair in Atlanta

Endless hot water. Lower utility bills. A sleek upgrade for modern homes.
We install and service tankless water heaters across Atlanta—with clear pricing, expert guidance, and honest recommendations.

Ready to stop running out of hot water? Tankless hot water heaters (also called on-demand water heaters) heat water only when you need it—saving you energy, space, and frustration.

At Fix & Flow, we help Atlanta homeowners upgrade to tankless systems that fit their lifestyle, family size, and energy goals. Whether you’re replacing an outdated unit or planning a remodel, we’ll help you choose the right model and handle the installation or repair from start to finish.

Why Go Tankless?

  • Endless Hot Water: Never run out, even during long showers or back-to-back use
  • Energy Efficiency: Only heats water when needed—no standby losses
  • Space-Saving Design: Wall-mounted units free up storage space
  • Longer Lifespan: Most systems last 15–20 years with proper maintenance
  • Lower Utility Bills: Efficient operation reduces gas or electric costs
  • Cleaner Water: No tank = less risk of sediment buildup over time

Need a Tankless Water Heater Repaired?

If your tankless water heater isn’t performing like it used to—maybe you’re noticing fluctuating temperatures, strange error codes, or no hot water at all—it’s probably time for a professional repair. These systems are efficient, but like any appliance, they need occasional attention to keep running smoothly.

Common issues include mineral buildup, ignition problems, or sensor failures, especially in older units or hard water areas like Atlanta.

At Fix & Flow, we specialize in diagnosing and repairing all major tankless brands. Whether it’s a quick fix or something more involved, we’ll get your hot water back up and running with honest advice and fast, reliable service.

We handle all major brands and offer responsive
same-day service in many cases.

Frequently Asked Questions

How much does a tankless water heater installation cost?

In Atlanta, the cost to install a tankless water heater typically ranges from $2,200 to $4,500. The final price depends on several factors, including the brand and model, whether it’s gas or electric, the complexity of the installation, and whether your home needs any upgrades to plumbing, gas lines, or electrical systems.

At Fix & Flow, we provide clear, upfront estimates with no surprises—and we’ll walk you through all your options so you can choose the setup that fits your home and budget. We also help identify any available rebates or tax incentives to reduce your total cost.

Can I replace a traditional tank water heater with a tankless one?

Yes, in most cases you can replace a traditional tank-style water heater with a tankless system—but there are a few important things to consider. Tankless units often require different venting, and depending on whether you choose gas or electric, you may need to upgrade your gas line, electrical panel, or plumbing to support the new system.

While the upfront work can be a bit more involved than a simple swap, the long-term benefits—endless hot water, lower energy bills, and a longer system lifespan—often make it well worth the investment. Our team at Fix & Flow can assess your setup and let you know exactly what’s needed to make the switch smoothly and safely.

Do tankless water heaters really last longer?

They do. While a traditional tank water heater typically lasts around 8–12 years, a well-maintained tankless system can run strong for 15 to 20 years or more. Because there’s no tank storing water 24/7, there’s less wear and tear, fewer chances for leaks, and a lower risk of rust or corrosion.

With regular maintenance—like flushing out mineral buildup—your tankless water heater can easily outlast a standard unit, giving you more years of reliable hot water and better long-term value for your home.

Will a tankless system meet the hot water needs of a large family?

Absolutely—as long as it’s sized correctly. One of the biggest perks of a tankless system is that it heats water on demand, so you’re not limited by the size of a tank. That means multiple showers, laundry, and dishes can all happen without running out of hot water—if the unit is built to handle your home’s peak usage.

We’ll help you choose the right model based on your family’s daily routine, number of bathrooms, and how often you all need hot water at once. With the right setup, a tankless water heater can keep up with your crew without breaking a sweat.

Is it worth switching to tankless just for energy savings alone?

For many homeowners, yes. Since tankless systems only heat water when you need it, you’re not paying to keep a big tank of water hot all day—especially when no one’s using it. That can lead to noticeable energy savings over time, especially in smaller households or homes with gaps between hot water use.

If your current water heater is on its last leg, switching to tankless can be a smart, efficient upgrade that pays off in the long run—not just in utility bills, but in reliability, space savings, and peace of mind. We’re happy to help you weigh the numbers and see if the savings make sense for your home.
