Tankless specialists

Endless hot water. Sized right, installed to code.

Tankless water heater installation, repair, and descaling across Austin and Marble Falls — sized to your household's real demand, vented and gas-supplied correctly, and maintained against Central Texas hard water.


What we do

Complete tankless care

From your first tankless conversion to the tenth annual descale — if it's on-demand hot water, we handle it.

Installation

Tank-to-tankless conversions and new installs, sized by flow rate and temperature rise — not guesswork. Gas line sizing, stainless venting, condensate handling, and permits done right the first time.

Repair

Error codes, ignition failures, flow sensor faults, and scale-choked heat exchangers — we diagnose to the part and repair when the unit has real life left. Honest call, every time.

Descaling & maintenance

Annual flushing that strips the hard-water scale killing your efficiency, plus burner inspection, filter cleaning, and a full performance check. The visit that keeps a 20-year unit on track.

The honest part

Tankless isn't for everyone

We'll tell you straight when a high-efficiency tank is the smarter buy — smaller households, tight budgets, or homes where the gas and venting upgrades would cost more than the unit itself. Tankless shines for larger households, simultaneous hot-water demand, and tight spaces. Our job is the right fit, not the most expensive option.

FAQ

Tankless questions, answered

Is a tankless water heater worth it in Central Texas?
For the right household, yes. Tankless units deliver endless hot water, mount on a wall to free up floor space, and run more efficiently than tanks — a real plus with our hard water, since there's no tank of water sitting and building sediment. The tradeoff is a higher upfront cost and often gas line or venting upgrades. We size the unit to your actual simultaneous demand so you're not paying for capacity you'll never use.
How do I know what size tankless unit I need?
Tankless sizing is about flow rate and temperature rise, not gallons. We look at your peak simultaneous demand — showers, dishwasher, laundry running at once — plus our winter groundwater temperature, and spec a unit that covers it. An undersized unit goes cold when two showers run; we make sure that doesn't happen.
Do tankless water heaters need maintenance?
Yes — annual descaling is the big one. Central Texas hard water leaves mineral scale on the heat exchanger, which quietly kills efficiency and shortens the unit's life. A yearly flush keeps it running like new. We offer maintenance visits, and we'll show you the warning signs (longer waits for hot water, fluctuating temperatures, error codes) that mean service is overdue.
Can you repair my tankless unit, or does it need replacement?
Most tankless problems are repairable: error codes, ignition failures, flow sensor issues, and scale buildup all have fixes. Tankless units last around 20 years with maintenance — roughly double a tank — so repair usually makes sense well into the unit's life. We'll diagnose honestly and tell you when replacement is the smarter call.
How long does a tankless installation take?
A straightforward replacement of an existing tankless unit is usually done in a day. Converting from a tank to tankless takes longer — new gas line sizing, venting, and sometimes electrical work for the condensate drain and controls. We'll walk the job first and give you a clear scope and timeline before any work starts.
