High-Efficiency Tankless Water Heater Installation in Texas

Unlimited Continuous Hot Water: Run multiple showers, the dishwasher, and laundry simultaneously without running out of hot water.

Longer Operational Lifespan: Tankless water heaters last 20+ years—more than double the lifespan of standard storage tanks.

Compact Space-Saving Design: Wall-mounted units free up valuable floor space in closets, utility rooms, or garages.

Zero Risk of 50-Gallon Tank Ruptures: Eliminate the danger of a massive water heater tank splitting and flooding your attic or home interior.

Lower Monthly Energy Bills: Condensing heat exchangers achieve up to 0.96 UEF energy efficiency ratings, reducing monthly utility costs.

Advanced Digital Temperature Control: Precise digital wall controllers allow you to set exact water output temperatures within one degree.

Gas Supply Line Sizing: High-output tankless units require 150,000 to 199,000 BTUs. We verify or upgrade your gas supply line to a full 3/4-inch dedicated pipe.

Concentric Direct Venting: We install dedicated twin-pipe polypropylene or stainless-steel venting through an exterior wall or roof.

Isolation Service Valves: We install commercial brass service valves to facilitate annual 30-minute mineral descaling flushes.

Dedicated Electrical Receptacle: We verify clean 120V power for the electronic control board and internal anti-freeze protection heating bands.

Combustion Air Clearance: We verify proper intake clearances to ensure safe, whisper-quiet operation.

Condensate Drain Line: High-efficiency condensing units produce acidic condensate; we install neutralizers and code-approved drains.

Tankless water heaters are sized based on incoming groundwater temperature and peak simultaneous flow rate in gallons per minute (GPM). In Texas, groundwater temperatures average 65°F to 70°F, allowing a standard 9.5 GPM Navien NPE-240A unit to comfortably supply three simultaneous showers and a kitchen faucet without any drop in water temperature.

Because Texas groundwater contains dissolved calcium and magnesium, mineral scale can slowly accumulate inside the copper and stainless-steel heat exchanger. We install accessible flush valves and provide annual descaling flushes using non-toxic food-grade solutions to keep your unit operating at peak thermal efficiency for decades.

Our 5-Step Turnkey Tankless Installation Process

Comprehensive Gas & Flow Sizing Evaluation: We evaluate your existing gas meter, piping capacity, and household hot water demand.

Safe Removal of Old Tank: Disconnect, drain, and recycle your old storage tank unit.

Gas & Venting Infrastructure Upgrade: Install high-flow gas piping, dedicated shutoff, and concentric venting.

Unit Mounting & Plumbing Connection: Securely wall-mount the tankless heater and connect to domestic hot/cold water loops.

System Commissioning & Permitting: Fire up the unit, calibrate water temperature, test flow rates, and pull all municipal city permits.
