Tankless vs. Tank Water Heaters: The Honest Math for Central Texas

We install both tank and tankless water heaters every week, so we have no horse in this race — and the honest answer is that tankless is a genuinely great technology that gets oversold to people who won't benefit from it. Here's the framework we actually use.

In the Waco area, a quality 50-gallon tank installed runs roughly $1,800–$2,800. A gas tankless conversion runs $3,500–$6,500 because the unit costs more and most conversions need a larger gas line and new venting. That gap is the number tankless has to earn back.

It earns it back two ways: efficiency (no standby heat loss, roughly $80–$150/year for a gas household) and lifespan (20+ years vs. 8–12 for a tank). Over twenty years, tankless usually wins the math — but you have to stay in the house to collect.

Your family genuinely runs out of hot water; you're staying put 5+ years; you have natural gas; you value the reclaimed closet or garage space; or you're already doing a remodel that makes the install cheaper. The endless-hot-water benefit is real and people love it.

You're on a budget and the heater just died (a tank gets hot water back today for half the price); your home is all-electric (whole-house electric tankless often demands a major panel upgrade that wrecks the economics); or you may sell within a few years. There's no shame in the proven option.

One non-negotiable either way: Central Texas hard water. A tankless unit needs an annual descale flush here, and a tank lasts years longer with a softener upstream. Whichever you choose, we'll quote both honestly — with installed prices, not teaser numbers. Call (254) 366-8281.
