A tankless water heater heats water on demand instead of storing it, so you get hot water that doesn’t run out, a smaller footprint on the wall, and lower standby energy loss. The trade-off is that a good result depends on right-sizing the unit, sizing the gas line, and venting it correctly. Infinity Plumbing installs and services a tankless water heater in Broken Arrow the right way, licensed for both plumbing and gas work in Oklahoma. Call 918-258-1818 for a written quote.
Tankless shows up most in Broken Arrow’s newer subdivisions and in remodels where a homeowner is tired of running out of hot water or wants the closet space back. It’s a strong fit for a lot of homes here, but not a drop-in swap you eyeball. Below is how it works, what a proper install takes on the gas and venting side, why hard water makes maintenance matter locally, and the repairs we handle when a unit acts up.
A traditional tank keeps 40 or 50 gallons hot around the clock, whether you use it or not, and refires whenever the stored water cools. A tankless unit skips the tank. When you open a hot tap, cold water flows through the unit, a gas burner or electric element fires, and the water is heated as it passes through a heat exchanger. Close the tap and it shuts off.
Because it only heats when you’re drawing water, there’s no tank of water losing heat all day, and there’s no tank to run empty. That’s where “endless hot water” comes from: as long as you stay within the unit’s flow rate, it keeps heating. Stay under that rate and the hot water simply doesn’t quit.
Homeowners here move to tankless for a few concrete reasons:
Tankless isn’t automatically right for every home. If your usage is low or your budget is tight today, a standard tank can still be the better value, and we’ll tell you so. If you’d rather repair or replace the tank you have, see our water heater repair in Broken Arrow page.
Sizing is where a tankless install succeeds or disappoints, and it comes down to flow rate and temperature rise.
Flow rate is how much hot water you might use at once, measured in gallons per minute, adding up the showers, sinks, tub, and appliances that could run together. Temperature rise is how far the unit has to lift the incoming water to reach your target, usually around 120 degrees. And here’s the Broken Arrow wrinkle: our incoming water is noticeably colder in winter than in summer. A unit that keeps up in July can fall behind in January if it was sized for the easy season. We size for a cold-weather worst case, using your home’s real fixture count and how your household actually uses hot water, so the unit still delivers when the ground is cold. An undersized unit is the most common reason people are disappointed with tankless, and it’s avoidable.
This is the part a lot of homeowners don’t see coming, and it’s why tankless is a licensed job, not a weekend swap.
Get the gas and venting right and the unit runs clean for years. Get them wrong and you get error codes, poor performance, or worse. Because tankless ties into your gas system, it’s worth having the same licensed crew handle it end to end. We cover gas and full-home plumbing as a licensed plumber for the Tulsa area.
Water across the Tulsa metro and eastern Oklahoma tends to run hard, Broken Arrow included, and hard water is the main thing that shortens a tankless unit’s life. As water heats, dissolved minerals drop out as scale and coat the heat exchanger, which is a narrow passage by design. Scale chokes the flow, drops efficiency, throws error codes, and if it’s ignored long enough it can damage the exchanger.
The fix is routine descaling, flushing the unit with a descaling solution through those isolation valves we install, usually once a year here. Many manufacturers tie their warranty to it. A lot of homeowners also pair a tankless unit with treatment so scale never gets a foothold. If hard water is a running problem in your home, ask about water filtration for Broken Arrow homes; softened or filtered water protects the tankless unit and everything downstream of it.
Already have a tankless unit that’s acting up? We service them, not just install them. The calls we see most:
We diagnose the actual fault, tell you whether it’s a maintenance flush, a part, or a replacement, and quote it in writing before we start.
Straight answer: install cost depends on the unit you choose, whether the gas line and venting need upgrading, and the condition of your existing connections, so a flat price over the phone would be a guess. A straightforward gas upgrade in a newer home costs less than one that needs a larger gas line and new venting in an older house. Repairs range from an affordable descaling flush to a specific part. What we can promise is how we price it: an upfront, written quote before any work starts, the assessment as a clear line item, and no surprise add-ons at the end. Financing is available if you’d rather spread an install over time.

We install and service tankless water heaters across Broken Arrow and the wider Tulsa metro, on both the Tulsa County and Wagoner County sides of the city, plus Tulsa, Bixby, Jenks, Owasso, and Sand Springs. Not sure whether tankless fits your home? Get in touch and we’ll walk you through it.
For many homes here, yes, especially larger or newer ones that run out of hot water with a tank, or households that want the space back and lower standby energy loss. For low-usage homes or a tight budget today, a standard tank can still be the better value. We size it to your real usage and tell you straight which one fits.
A well-maintained tankless unit generally outlasts a standard tank, often noticeably so. The key word is maintained. With hard water common around Broken Arrow, annual descaling is what protects the heat exchanger and keeps the unit in service for the long haul.
Often, yes. A gas tankless unit fires at a much higher rate than a tank heater while it runs, so the existing gas line and meter capacity have to be checked and are sometimes upgraded. We’re licensed for gas work in Oklahoma and size this as part of the install so the unit gets the fuel it needs.
Hard water leaves mineral scale on the heat exchanger as it heats. That narrow passage clogs, which drops efficiency, triggers error codes, and can eventually damage the unit. Flushing it with a descaling solution, usually once a year here, clears the scale. Many warranties require it.
We do both. We service tankless units for error codes, ignition and flame-sensing faults, flow problems, clogged filters, and scale, and we descale them. We diagnose the real cause first and tell you whether it’s maintenance, a part, or a replacement before quoting.
Tankless gives you endless hot water, but not necessarily instant hot water at a far fixture; the water still has to travel the pipe from the unit to the tap. If instant delivery matters to you, we can talk through a recirculation option during the install.
