Water Heater Guides for New Braunfels Homeowners

These guides answer the water heater questions New Braunfels homeowners ask most, written for this town rather than a national average. Very hard water, a fuel that depends on your street, and a City permit on every replacement change the answer to almost every question.

All ten water heater guides

• Leaking water heater

  Shut it off, find the source, and learn which leaks can be fixed and which mean the tank is done.

• No hot water

  The breaker, reset button, pilot and thermocouple checks to run first, and what the common fixes cost.

• Replacement cost

  Typical price ranges by tank size, plus the permit, expansion tank and pan items that move the number here.

• Tankless cost

  Typical tankless ranges, the gas-versus-electric install gap, and the descaling cost hard water adds.

• Lifespan & warning signs

  Manufacturer lifespans, what hard water does to them, and the warning signs to replace before it floods.

• Tankless vs tank

  Cost, lifespan, hard water, big households and no-gas homes, compared honestly.

• Hard water & softeners

  How hard the water is, what it does to each kind of heater and where a softener fits.

• Big box vs local plumber

  Who really shows up, what the store's base price leaves out, and how to compare quotes.

• Gas vs electric & sizing

  Find your fuel, compare gas and electric, then size the heater from your busiest hour.

• Permits

  The City's rule, who pulls the permit, what the inspector checks and why skipping it backfires.

Where should I start?

Pick the line that sounds like your house today.

• Water on the floor: what to do when a water heater is leaking starts with the shutoff.
• Water simply cold: the no hot water guide walks through the causes for gas and electric water heaters.
• Repair or replace: how long water heaters last, then the replacement cost guide.
• Thinking about tankless: tankless versus tank, then the tankless cost guide.
• Choosing a size or fuel: gas vs electric and sizing.
• Comparing who to hire: big-box store vs a local plumber.

What makes New Braunfels different?

Three local facts run through every guide on this page:

• Hard water: NBU's 2019 water quality report (opens in a new tab) (2018 data) put hardness at 8.1 to 19.5 grains per gallon, average 15.1. See hard water and water heaters.
• Fuel: natural gas reaches many parts of the city but not all, and electricity comes from NBU, Guadalupe Valley Electric Cooperative (GVEC) or Pedernales Electric depending on where you live.
• Permits: the City requires one to replace a water heater. Water heater permits in New Braunfels explains why a quote without one is a warning sign.

How are the prices in these guides worked out?

Every cost figure is a typical range compiled from several national cost guides and rounded. A standard tank installed typically runs about $1,000–$3,400, and tankless about $1,600–$4,500. See how these ranges are calculated. You'll get the real price for your home before any work starts.

How are the guides written?

Each guide opens with the direct answer, then the reasons. Local facts come from the City, NBU and the Texas plumbing board (opens in a new tab), and nothing is guessed.

Lifespans come from manufacturers (opens in a new tab) and independent testers: tanks typically last 8 to 15 years, tankless water heaters 15 to 20. Where the answer depends on your house, the guide says so, and a call back gets you the specifics.
