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. Most of Spicewood lives on wells and septic — pressure tanks, iron and sediment in the water, and aerobic systems that need real maintenance, not a city-water playbook. 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.
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.
