A tankless water heater takes a different approach: instead of keeping a full tank of water hot around the clock, it heats water only while a tap is open. When water starts moving, a flow sensor notices, a powerful burner or electric element fires, and the water is heated as it passes through a compact heat exchanger. The benefits are real: no standby heat loss, hot water that does not run out during back-to-back showers, a wall-mounted unit that frees up floor space, and a service life that often reaches twenty years with maintenance. For many households in Texarkana, TX, that makes tankless a smart upgrade.
Sizing is where tankless installs succeed or fail. We work from two numbers, flow rate and temperature rise: add up the fixtures you realistically run at the same time in gallons per minute, then factor in how cold the incoming water gets in winter, since a unit that delivers five gallons per minute at a mild rise may deliver far less when the groundwater is cold. Then comes the infrastructure. A whole-home gas unit can draw several times the gas of a standard tank, which often means a larger gas line or confirming the meter can keep up. Venting must match the unit, and electric tankless models can need well over 100 amps, sometimes enough to require a panel upgrade.
Every tankless install from Texarkana Water Heater includes isolation service valves so future descaling takes minutes instead of hours, a clean gas connection with a sediment trap, correctly pitched and terminated venting, and a pressure relief valve piped to a safe location. If your water is hard, we talk through scale protection, since mineral buildup is what shortens tankless life most. We can add recirculation for faster hot water at distant bathrooms, set the temperature, handle permits where required, and walk you through maintenance before we leave.

Symptoms That Mean It's Time to Call
Most tanks announce trouble weeks or months ahead with rumbling noises, rusty water, or hot showers that keep getting shorter. These are the red flags our technicians see most often before a breakdown:
- A distant bath or detached space that needs its own hot water source
- A remodel that would benefit from a compact wall-mounted heater
- A home remodel or new build where the gas line and venting can be planned from scratch
- A tank water heater that is ten years old or more and due for replacement
- Preferring a heater that can be repaired and maintained instead of replaced every decade
- Energy bills that reflect a tank heating water around the clock
- A tank that cannot keep up with your household's morning routine
- More people or more fixtures than your current heater was sized for
Don't Wait for a Total Failure
A little rust-colored water or a relief valve that drips now and then can be the first hint of a tank that is close to the end. If you notice any of these signs, contact Texarkana Water Heater at (903) 202-2374 for a prompt inspection.

Why This Job Calls for a Pro
Why not install a tankless unit yourself? Because the risks and the details stack up quickly. Gas piping must be sized for a burner that may draw nearly 199,000 BTU, and leaks or undersized lines are both dangerous and costly. Venting has to match the unit exactly, with the right material, slope, and termination clearances, or combustion gases can end up where they do not belong. Electric models may need a panel upgrade, and warranty terms often depend on a qualified installation. Permits and inspections are common requirements as well.
We take the guesswork out of going tankless. That starts with sizing for your busiest hour and coldest water, then confirming your gas, venting, and electrical can support the unit. We install with service valves for descaling, proper relief valve discharge, and venting built to the manual, then test under real demand before we leave. If a tankless unit is not the best choice for your home, because of cost, supply limits, or how you use hot water, we say so and help you compare other options honestly.
From Your Call to Hot Water
Good water heater work comes down to a consistent routine, and ours starts with a real diagnosis instead of a guess. Here's what you can expect when you choose Texarkana Water Heater:
Size It Right
Sizing starts with your peak demand in GPM and the temperature rise needed for cold winter water. That pairing tells us which unit will actually keep up.
Supply & Venting Plan
We confirm the gas line and meter can feed the burner's full BTU demand, plan the right venting, and check the panel for electric units before any price is set.
Clean, Code-Minded Installation
Every connection follows the manual and local code: gas, venting, relief valve discharge, condensate, and isolation valves for future maintenance, with permits handled where required.
Startup & Verification
Startup includes a full-flow test, a gas pressure check with the burner at high fire, a leak check on every joint, and a plain explanation of settings and maintenance.
Repair or Replace? Let's Figure It Out.
We give honest advice and upfront pricing on every job, big or small.

A few simple habits, like an annual flush and a quick look at the relief valve, can add years to a tank. Start with these practical measures our team relies on:
- Descale the heat exchanger once a year, or more often with hard water
- Clean the inlet water filter screen a few times a year
- Pay attention to error codes; they point to issues that are cheaper to fix early
- Make sure the outside vent and intake are never blocked
- A setting near 120F limits scalding and reduces scale formation
- In freezing weather, keep the unit powered and insulate exposed piping
- Treating hard water protects the heat exchanger from mineral buildup
DIY vs. Professional Tankless Water Heater Installation
Online videos may help in a pinch, yet lasting repairs and code-compliant installs depend on correct venting, proper relief valve discharge piping, and a trained technician. Here's how the two approaches stack up:
| Factor | Doing It Yourself | Professional Service |
|---|---|---|
| Capacity | Chosen by brand or price alone | Calculated for your coldest months |
| Gas Supply | Undersized line starves the burner | Gas pressure tested at high fire |
| Venting | Clearances and pitch overlooked | Venting built to the manufacturer's specs |
| Electrical | Panel capacity not checked for electric units | Panel and circuits confirmed before install |
| Future Service | Service access ignored | Isolation valves installed for quick descaling |
| Result | Lukewarm water and error codes | Safe, inspected, and working as designed |
