The conventional storage tank water heater remains the volume residential water heater across the US — roughly 75% of all installs. A tank water heater stores 30–80 gallons of preheated water in an insulated steel tank, fired by gas atmospheric burner, gas power-vent, gas direct-vent, or electric resistance elements. Compared to tankless, storage tanks have lower upfront cost, simpler install (no gas-line resizing, no PVC venting), and tolerate higher peak demand events without GPM limits. The trade-off is standby losses (continuous reheating to maintain temperature) and a finite reservoir.
