Endless hot water, wall-mounted space savings, and a 20-year service life — if the install is done right for hard Central Texas water. Get matched with a Lakeway installer who does it right.
Two minutes now beats waiting on hold. No obligation.

A properly sized tankless unit heats water continuously at a flow rate instead of draining a stored supply — hot water for as long as you want it, from a unit hanging on the wall instead of eating a closet. It commonly outlasts two tank replacements.
The catch in this region is water quality. Lake Travis municipal water runs hard here, and well pockets on the edges of town run harder — scale is a fact of life for Lakeway water heaters and fixtures. Scale is the number one killer of tankless heat exchangers, and several manufacturers scale their warranty terms to water hardness — that's where the fine print lives.
An install done right here includes isolation and flush valves for annual descaling, ideally treatment upstream, and a gas-line check — tankless burners draw far more than the tank they replace, and many homes need a line upsize. A licensed pro verifies that before quoting, not after.
The right question isn't gallons — it's simultaneous demand: two showers, a filling tub, and a dishwasher on a Saturday. Lakeway homes are big, glassy, and lake-facing — multi-system layouts fighting brutal west sun, with the original sections off Lakeway Boulevard now running equipment past the 12-year mark. Around Rough Hollow, Serene Hills, The Hills, and Flintrock Falls, installers in our network size flow rate and temperature rise for that reality, and will say honestly when a big household is better served by two units or a recirculation loop for far-end bathrooms.
Most companies make you call, hold, and explain everything twice. We flipped it — you tell us once, we do the matching.
The form above takes two minutes — no account, no phone tree. More detail means a faster, better match.

Your pro diagnoses, quotes, and waits for your yes. No invoice roulette, no pressure — that's the network rule.
Gas tankless installs typically run mid four figures — more than a tank swap, reflecting venting, gas line, and valve work. Against a 20-year service life and two avoided tank replacements, the math is closer than the sticker suggests.
Annual descaling keeps the warranty comfortable in local water — a quick service when isolation valves were installed with the unit. Pair it with a softener and both the maintenance interval and the fine print relax. Your quote comes before any work; your call after.
