TL;DR
Tankless gives endless hot water within its rated flow — but only if it's sized to your demand and the gas, electric, venting, and water conditions are right. Resolv measures demand, verifies utilities, and prices the complete tankless installation for Odessa homes.
- Sized by simultaneous fixture flow and the temperature rise for Odessa's incoming water
- May require gas-line, electrical, venting, or condensate work versus a simple tank swap
- Endless within its rated capacity — it cannot exceed the designed output
- Manufacturer maintenance (descaling) matters in hard-water areas

Potential complication
Gas-line, electrical, venting, condensate, or water-quality work may make conversion more involved than a tank replacement.
