A traditional tank costs less upfront — about $600–$2,500 installed — and is simple to service. A tankless costs more ($1,800–$5,500) but delivers endless hot water and lasts 15–20 years versus 8–12 for a tank. In Fort Worth’s hard water, tankless needs annual flushing. For most homeowners staying put, tankless wins long-term.
| Factor | Tank | Tankless |
|---|---|---|
| Installed cost (2026) | $600 – $2,500 | $1,800 – $5,500 |
| Lifespan | 8 – 12 years | 15 – 20 years |
| Hot water | Limited by tank size | Endless, on demand |
| Space | Bulky tank | Compact, wall-mounted |
| Energy use | Standby loss | Lower (heats on demand) |
| Hard-water care | Periodic flush | Annual flush essential |
Fort Worth’s hard water scales up any water heater, but tankless units are especially sensitive — without annual flushing, scale steals efficiency and shortens lifespan. Pairing tankless with a water softener, or staying on a maintenance plan, protects your investment and keeps it efficient.
Astar installs both. Compare a tankless water heater against a tank water heater, or ask us for a straight recommendation. Call (817) 290-3373.
For many homes, yes — endless hot water and a 15–20 year lifespan offset the higher upfront cost, especially if you’ll stay put. The key local caveat is hard water: tankless needs annual flushing (or a softener) to stay efficient here.
Tankless typically runs $1,800–$5,500 installed versus $600–$2,500 for a tank — often roughly double upfront. Tankless installs may also need gas-line or electrical upgrades, which we’d quote before any work.
Around 15–20 years with proper maintenance, compared to 8–12 for a traditional tank. In hard-water areas like Fort Worth, annual flushing is essential to reach that lifespan.
