What is the difference between a tank and tankless water heater?

A traditional tank water heater stores 40–80 gallons of pre-heated water and reheats it continuously to keep it ready. A tankless (on-demand) water heater heats water only when you need it — no storage, no standby heat loss, no running out.

Tankless units cost more upfront but last nearly twice as long and use 20–30% less energy. For households that run multiple showers, a dishwasher, and laundry simultaneously, tankless is often a life-quality upgrade.
