How to Select the Right Water Heater: Capacity, Brands & Key Features
Choosing the correct size and type prevents frequent breakdowns and wasted energy. For 1–2 people a 30–40 gallon tank (or tankless unit rated 5–7 GPM) is usually sufficient. Families of 3–4 typically need 50–60 gallons or 8–10 GPM tankless flow. Larger households often require 60–80+ gallons or high-capacity tankless systems. Among the brands most frequently installed and serviced in the Austin area are:
- Rinnai – top choice for reliable, long-lasting tankless performance
- Rheem / Ruud – excellent balance of price, quality and local parts availability
- A.O. Smith – strong traditional tanks and best-in-class hybrid models
- Navien – premium tankless with advanced efficiency and smart controls
- Bradford White – durable tank units especially suited to hard-water regions
The Installation & Replacement Process in the Greater Austin Area
Professional installation is critical for safety, code compliance, and long-term reliability. Our licensed plumbers normally complete a standard tank water heater replacement in 3–5 hours and most tankless conversions in 5–8 hours. The process always includes safe disconnection and removal of the old unit, inspection of gas lines / electrical wiring / venting, installation of required expansion tanks (mandatory in Texas), proper dielectric unions, new shut-off valves, pressure testing for leaks, precise temperature setting (usually 120°F), and a final operation check. We offer same-day emergency service throughout Austin, Round Rock, Cedar Park, Pflugerville, Leander, and surrounding communities whenever you experience a sudden leak or loss of hot water.
Maintenance Tips to Make Your Water Heater Last 12–20 Years
Regular care dramatically extends equipment life in Austin’s challenging water conditions. Annual or bi-annual flushing removes sediment buildup that causes noises, inefficiency, and premature failure. Checking and replacing the sacrificial anode rod every 2–4 years protects the tank from corrosion. Inspecting the temperature & pressure relief valve and drain valve once a year prevents dangerous pressure issues. Keeping the thermostat at 120°F reduces scale formation and saves energy. Installing a whole-house water softener or point-of-use scale inhibitor provides the single biggest longevity boost for tank and tankless units alike. Scheduling a professional tune-up once a year catches small problems before they become expensive emergencies.
