Do I need a bigger gas line for a tankless heater?

Often, yes. A tankless burner draws considerably more gas while firing than a tank unit does, and the half-inch line that served a 40-gallon heater frequently can't supply it. We check meter and line capacity before quoting, so the gas work is priced up front rather than discovered mid-installation.

How often does a tankless unit need flushing in this area?

Roughly once a year on our water. Minerals deposit inside the heat exchanger where the water is hottest, restricting flow and eventually causing error codes. We install isolation valves as standard so the flush is a simple service call rather than a labour-heavy job.

Will a tankless heater really never run out of hot water?

It won't run out, but it is limited by flow rate — it can only raise so many gallons per minute by so many degrees. That's why correct sizing matters. A unit sized for mild weather can disappoint in January, when incoming groundwater is much colder and two fixtures are running at once.

Which tankless brands do you install?

Navien and Rheem. Both have solid parts availability and service support, which matters when a unit needs a component in year six.

Is tankless always the better choice?

No, and we'll say so. If your gas and venting would need substantial modification, your household hot-water use is modest, or you're unlikely to keep up with annual flushing, a good tank heater is often the better value. We give you both numbers and let you decide.

Tankless Water Heaters in Porter, TX

A tankless water heater heats water as it flows, which means no 50-gallon tank sitting in a closet slowly corroding, and no running out partway through the third shower. Texas Plumber Connection installs, services and repairs Navien and Rheem tankless units across Porter, Spring, The Woodlands, Conroe and the surrounding area — and just as importantly, we'll tell you when a tankless isn't the right call for your house.

They're excellent equipment. They're also less forgiving than a tank, and north Houston's water chemistry is exactly the thing they're least forgiving about.

Sizing matters more than the brand

The most common tankless complaint we're called out to isn't a broken unit — it's an undersized one. A tankless heater is rated to raise incoming water by a certain number of degrees at a certain flow rate, and in winter the groundwater feeding your house is meaningfully colder than it is in July. A unit sized on a mild-day assumption will keep up in September and disappoint you in January when someone runs a shower and the dishwasher at once.

We size on winter inlet temperature and on how the household actually uses hot water — two showers at the same time, a soaking tub, a large-capacity washer — rather than on square footage. Getting that wrong is the difference between a heater you never think about and one you resent.

Gas and venting are usually the real work

Swapping a tank for a tankless is rarely a like-for-like exchange. A tankless burner draws far more gas while it's firing, so the existing gas line is often undersized — a half-inch run that was fine for a 40-gallon tank frequently isn't. Venting changes too: most condensing units need their own sealed vent and a condensate drain, and the old flue can't simply be reused.

None of that is a reason not to do it. It's a reason to price it honestly up front, which is what we do rather than discovering it halfway through the afternoon.

Descaling: the part nobody mentions at the point of sale

Hard water is the tankless heater's main adversary. Instead of dropping sediment into a tank where it sits harmlessly for years, minerals deposit inside a narrow heat exchanger where the water is hottest. Scale there restricts flow, forces the unit to work harder, and eventually throws error codes or shortens the exchanger's life.

Flushing the unit — circulating a descaling solution through the heat exchanger — is routine maintenance, not a repair. On our water, roughly annually is sensible. Units installed with isolation valves make this a straightforward service call; units installed without them make it an expensive one, which is why we fit them as standard.

What we do

Assess the house: gas meter and line capacity, venting route, electrical, water hardness, and where the unit can be mounted safely.
Size the unit on winter inlet temperature and real simultaneous demand, not a rule of thumb.
Quote the whole job — gas, venting, condensate, isolation valves, permitting — so there are no mid-job surprises.
Install and commission it, confirming gas pressure under load and that the unit holds temperature at full flow.
Show you the maintenance, including how the flush works and how often it's worth doing here.

Repairs and error codes

If you already have a tankless unit that's throwing codes, cycling cold, or losing output, it's often scale, a dirty inlet filter, a venting or combustion-air issue, or an ignition component — not a dead heater. We diagnose Navien and Rheem units and repair rather than replace wherever the unit justifies it.

Serving Porter and the surrounding area

We install across Porter, New Caney, Spring, The Woodlands, Conroe, Oak Ridge North, Cut and Shoot, Humble, Atascocita and Tomball. Newer builds in Tavola, Grand Central Park and Creekside Park are often straightforward conversions; homes from the 1970s and 80s in Porter Heights, River Plantation or the older Woodlands villages more often need gas line work to support the change, and we'll say so before you commit.

No service fee to look at it, estimates Monday through Saturday 8am to 8pm, and financing through Synchrony. Call (832) 885-9820.
