Yes — tankless water heaters are typically 20% to 35% more energy-efficient than traditional tank water heaters because they eliminate standby heat loss. A tank water heater spends most of its life maintaining temperature on stored water you’re not using; a tankless unit only fires up when you need hot water.
Where the savings come from
- No standby losses — no hot water sitting in a tank
- Condensing models capture additional flue energy
- Modulating burners match output to demand
- Lower minimum fuel use during low-demand cycles
- Longer lifespan reduces equipment replacement cost
