What Is a Tankless Water Heater?
A tankless water heater is an on-demand water heater that heats water as it flows through the unit, rather than storing it in a tank.
These systems are designed to:
- Provide hot water instantly when needed.
- Reduce energy waste by eliminating standby heating.
- Operate efficiently in smaller or off-grid environments.
- Fit into compact installation spaces.
Because they only heat water during use, tankless water heaters are often used in cabins, small homes, and supplemental hot water applications. For help comparing models and sizing your system, you can review our Tankless Water Heater Selection Guide.
