Water Heater Repair & Replacement in New Braunfels, TX

Leaking right now? Three things before anything else

1. Shut off the water. Turn the cold-water supply valve on the pipe at the top of the heater clockwise until it stops.
2. Cut the power. Electric unit: switch off its breaker at the panel. Gas unit: turn the gas control knob on the front of the heater to OFF.
3. Then call or text (830) 243-5644. Answered 24/7, and you'll get a call right back.

Smell gas? Leave the house, don't flip any switches, and call 911 and then CenterPoint Energy's leak line at 888-876-5786 from outside.

Why do water heaters wear out faster in New Braunfels?

Three local facts shape almost every water heater job here: very hard water, a gas-or-electric split that depends on your street, and a City permit on every replacement. Knowing them helps you read a quote and keep a new heater going longer.

Hard water builds sediment and scale

New Braunfels Utilities (NBU)'s 2019 water quality report (opens in a new tab) (2018 data) put hardness at 8.1 to 19.5 grains per gallon, with an average of 15.1. That works out to roughly 258 mg/L, well past the U.S. Geological Survey (USGS) line for "very hard" water at 180. NBU's newer reports don't publish a hardness figure.

In a tank, those minerals settle on the bottom as sediment. The burner or lower element then heats through a crusty layer, which is the rumbling and popping many homeowners hear. In a tankless water heater, the same minerals coat the heat exchanger as scale.

• Flush the tank: at least once a year, and more often with hard water.
• Check the anode rod: it's the part that corrodes so the tank doesn't. Replace it when the core wire starts to show.
• Descale tankless: at least once a year, through isolation valves if you have them.

The hard water guide covers softeners and the anode trade-off.

Gas or electric depends on where you live

The City's utilities page (opens in a new tab) says CenterPoint Energy supplies natural gas to many areas of New Braunfels, but not all of them. Veramendi is the one neighborhood with a confirmed gas provider (CenterPoint). Everywhere else, check which fuel your home has before you shop for a new heater.

Electric service splits as well. NBU serves most of the city, Guadalupe Valley Electric Cooperative (GVEC) serves the area south of County Line Road, and Pedernales Electric serves the area west of town out FM 306.

If there's no gas line on your street, a gas heater means a new line, and that changes the price. The gas vs electric and sizing guide shows how to tell which one you have.

A permit comes with every replacement

The City's permits page (opens in a new tab) requires a permit to install, alter, repair, remove or replace any plumbing or gas system, and that covers swapping a water heater. It's normally pulled by the licensed plumber doing the job, through the City's online portal. The fee isn't published as a single figure.

New Braunfels adopted the 2021 International Plumbing Code (opens in a new tab) in 2023. That code is where the expansion tank rule (section 607.3) and the drain pan rule (section 504.7) come from, so a proper quote accounts for both. The permit guide has the details.

What does a water heater cost in New Braunfels?

Most homeowners pay about $1,000 to $3,400 for a standard tank installed, and about $1,600 to $4,500 for a tankless water heater.

Repair visits usually cost $200 to $850, with the average near $550. These are typical ranges compiled from national cost guides, not a quote for your home. You'll get your real price on the call, before any work starts.

What moves the number here: tank size, gas or electric, where the heater sits, and the code parts your home needs. The pricing page breaks it down by size and by repair.

How does it work?

Three steps, and nothing is committed until you say yes to a price.

1. Call, text or send the form. Tell us what's going on and give your ZIP code.
2. Get a call right back with a price. A few questions about the tank, the fuel and where it sits, then a price before any work starts.
3. Get your hot water back. A like-for-like tank swap usually takes about 1 to 3 hours, with the permit and haul-away on the quote.

Have these handy if you can: the ZIP code, what the heater is doing, and whether it's gas or electric. The tank size and age off the label help too, but none of it is required to call.

Should you repair, replace or go tankless?

Repair when the heater is under about 8 years old and one part has failed. From about 8 years on, repair only a small, inexpensive part on a dry tank. Replace when water comes from the tank body, when the tank wall rusts, or when an older tank needs a second costly part. Go tankless when you want endless hot water and are ready for a higher up-front cost.

• Repair: a thermostat, heating element, thermocouple or gas valve. A leak at a top fitting is usually fixable, and a thermocouple typically runs $125 to $250.
• Replace: water from the tank body means the steel has rusted through, and no part fixes that. Tanks typically last 8 to 15 years, and hard water pushes them toward the short end.
• Tankless: hot water on demand and a lifespan of 15 to 20 years. In this water, plan on a descale at least once a year.

A tank-to-tankless conversion usually takes 4 to 6 hours, because the gas line, venting or electrical circuit often changes. Compare the two side by side in tankless vs tank.

East of I-35, that includes Legend Point on Klein Road, Heather Glen and Kowald Lane near FM 306, and Voss Farms off FM 1044. To the northeast it reaches Freiheit along FM 1101 and the acreage at Havenwood off FM 1102.

Out west, it covers Vintage Oaks and Copper Ridge off Highway 46, then up FM 306 to Canyon Lake, Sattler and Startzville, and on to Bulverde, Spring Branch and Rockwall Ranch. See every neighborhood on the service areas list.

What makes this different?

Four plain things, none of them hard to check.

• Answered 24/7. Nights, weekends and holidays included. Call or text any time and you'll get a call right back.
• A price before any work. You'll hear the number, including any trip charge, before anything starts. Nothing is committed until you say yes.
• Published ranges. Typical costs are on the pricing page, so you can tell whether a quote sits in the normal band before you agree to it.
• License number on request. Texas master plumber license numbers start with "M", and Board Rule 367.10 puts that number on written estimates and invoices. Ask for it and look it up on the state's public license search.

A fair replacement quote also lists the water heater, the permit, haul-away and any code parts line by line, so nothing gets added on the day.
