What Size Tankless Do You Need? An Austin GPM Guide
Tankless sizing is about flow rate, gallons per minute (GPM), not tank gallons. Undersizing is the single most common mistake we fix, and it always shows up the same way: the shower goes cold when the dishwasher runs. Here's how we size:
- 1-2 bathrooms, 1-2 people: 6-7 GPM is usually plenty.
- 3 bathrooms, 3-4 people: 8-9 GPM covers two simultaneous showers plus a dishwasher.
- 4+ bathrooms or luxury homes: 10-11 GPM, or two units in parallel for true endless capacity.
| Household | Recommended flow | What it covers |
|---|---|---|
| 1-2 bathrooms, 1-2 people | 6-7 GPM | One shower plus one appliance at a time |
| 3 bathrooms, 3-4 people | 8-9 GPM | Two simultaneous showers plus a dishwasher |
| 4+ bathrooms or luxury homes | 10-11 GPM, or two units in parallel | True endless capacity at peak demand |
The Austin factor: our winter groundwater drops into the mid-40s F, which cuts a unit's effective GPM versus its summer rating. We size for January performance, not July. That's the difference between a unit that works and a unit that works year-round.
Gas Line and Venting: The Work Behind the Unit
The tankless unit on the wall is the visible half of the job. The invisible half, and the part cheap installers botch, is fuel and exhaust. Tankless burners fire at 150,000-199,000 BTU, roughly four times a tank unit, so most Austin homes need their gas line upsized from 1/2-inch to 3/4-inch or 1-inch. Venting must be dedicated Category III stainless or Category IV PVC per the manufacturer's spec, with proper clearances and condensate drainage on high-efficiency condensing models. Every installation is permitted and built to code, because we do this work to the book.
Tankless Water Heater Installation Cost in Austin
Realistic Austin numbers, all-in:
- Tankless unit alone (installed, simple swap): $3,000-$4,500.
- Tank-to-tankless conversion: $3,800-$6,000. The range depends on gas-line upsizing distance and venting runs.
- Premium or dual-unit setups: $6,500-$9,500 for large luxury homes.
| Job | All-in range |
|---|---|
| Tankless unit alone (installed, simple swap) | $3,000-$4,500 |
| Tank-to-tankless conversion | $3,800-$6,000 |
| Premium or dual-unit setups (large luxury homes) | $6,500-$9,500 |
Every quote is written and itemized: unit, gas work, venting, condensate, and haul-away. Federal energy tax credits for high-efficiency (0.95+ UEF) units can offset a meaningful chunk. Ask us what's current this year.
Tankless Brands We Install and Service
We install and warranty-service the brands with the best parts availability and track records in Central Texas: Rinnai (the reliability benchmark), Navien (best value in condensing technology), Rheem and AO Smith (strong local parts networks), and Noritz.

Austin Energy Rebates and Tax Credits: Don't Leave Money on the Table
High-efficiency water heating pays you back twice: lower monthly bills, plus incentives that cut the upfront cost. Here's what's real right now:
- Austin Energy heat-pump rebate: Austin Energy offers a $1,000 rebate on qualifying ENERGY STAR certified heat pump (hybrid) water heaters installed in homes with Austin Energy electric service. Applications must be submitted within 90 days of purchase, and permitting requirements apply. Considering electric? Our hybrid heat-pump page has the details.
- Tankless incentives: utility rebate programs change from year to year, so always confirm what's active before you buy. When we quote your tankless installation, we'll tell you exactly which Austin Energy rebates and federal tax credits your unit qualifies for at that time.
- Federal tax credits: high-efficiency water heaters (including qualifying heat-pump and condensing tankless models) have been eligible for federal energy tax credits. The amounts and rules shift with legislation. Ask us what's current this year and we'll factor it into your quote.
We provide installation documentation and guidance on submitting your rebate application correctly the first time.
