FAQs — Austin Water Heaters
How long should a water heater last in Austin?
Tank units: typically 8–12 years. Tankless: 15–20 years with proper descaling. Hard water shortens life without maintenance.
Is repair or replacement more cost-effective?
If a tank is ~10+ years old or showing corrosion/leaks, replacement usually wins on reliability and long-term cost. For newer systems with simple issues, repair is often best.
What size water heater do I need?
Tanks are sized by family size/usage (40–50–75 gal). Tankless is sized by simultaneous fixtures (GPM) and winter inlet temps.
Why is my tankless shutting off or throwing codes?
Common causes: scale buildup, flow restrictions, venting issues, or gas supply limits. Annual descaling and correct gas/vent sizing are critical in Austin.
Do you install recirculation for faster hot water?
Yes — we design recirculation for both tank and tankless to reduce wait times and water waste.
