Tulsa Tankless Water Heater Installation and Repair

Compact Design. Built for Your Needs.

Old units heat and reheat water constantly—even when no one’s using it. Modern on-demand equipment eliminates that cycle, reducing waste and reclaiming valuable square footage. At Mullin Plumbing, we help you make the switch with expert recommendations based on usage volume, building layout, and pressure delivery.

Our licensed technicians configure each setup to deliver reliable heat without energy drag. From day-to-day use to peak demand, we tailor the process for clean results, consistent flow, and dependable output—no oversized tanks, no excess runtime.

Advanced Planning for Seamless Performance

Tankless equipment isn’t a plug-and-play upgrade—it requires planning that accounts for infrastructure, flow rate, fuel capacity, and water quality. Mullin Plumbing brings the field experience and design insight needed to help you get it right the first time.

• Pre-Conversion Load Assessment: We evaluate your plumbing and electrical setup to determine if upgrades are needed before integrating on-demand tech. That includes checking panel draw, pipe sizing, and gas line capacity—so performance doesn’t suffer under demand.
• Commercial and Multi-Unit Integration: For offices, shops, and facilities with multiple points of use, we configure tankless units to meet shared output needs without staggered flow or temperature drops.
• Filtration and Mineral Adaptation: Tankless models are sensitive to mineral buildup. We help protect your equipment with inline filtration, isolation valves, and maintenance-ready layouts that prevent scale and preserve warranty compliance.
• Code-Ready Install Coordination: Local installs often require venting changes, clearance adjustments, or a permit. We handle all documentation, schedule any required inspections, and make sure the final product passes with zero delays.
• Diagnostic Support and Smart Tech Tuning: Many modern units include Wi-Fi controls and smart sensors. We offer programming support, update firmware, and diagnose errors tied to flow sensors or burner calibration.

Why Tankless Clients Choose Mullin for Precision Work

Tankless upgrades only deliver when every piece is aligned, we approach each project like a long-term asset, not a quick swap. Our crews are trained to tune gas input, adapt to hard water conditions, and troubleshoot variables that impact heating consistency.

We don’t treat tankless like a one-size solution. Instead, we take time to size each unit properly, add protection where needed, and map the install for performance—not just fit. That includes verifying permit requirements, optimizing line clearance, and testing under actual peak-use conditions. For property owners who want savings without surprises, this kind of detail is what sets us apart.

Your Upgrade Deserves More Than a Drop-In Unit

Tankless water heating isn’t just a switch—it’s a step toward smarter energy use, longer equipment life, and cleaner mechanical design. At Mullin Plumbing, we don’t just mount the box and walk out. We test, refine, and build around your goals—fuel use, layout, and daily volume.
