Instead of storing hot water in a tank, a tankless water heater heats water only when you need it. This on-demand heating provides a continuous supply of hot water without the wait or energy loss associated with traditional storage tanks.

Navien’s high-efficiency condensing technology heats water precisely when needed, eliminating standby heat loss. This results in lower energy consumption and reduced utility bills compared to conventional tank water heaters.

No, you will not run out of hot water under typical use. Tankless water heaters provide a continuous supply of hot water by heating it as it flows through the unit, so you don’t have to ration hot water during showers, laundry or dishwashing.

However, the unit’s maximum flow rate limits how much hot water it can deliver at once. If multiple fixtures demand more hot water than the unit’s capacity, the flow may be reduced. For larger households or simultaneous heavy use, multiple units or a properly sized model can ensure adequate hot water supply.

Tankless units are compact and wall-mounted, often about the size of a small suitcase. This design frees up valuable floor space compared to traditional tank heaters.

Yes, regular maintenance is important to keep your tankless water heater operating at peak performance and to help extend its lifespan. This typically includes descaling the unit to prevent mineral buildup, cleaning or replacing filters and checking system components for optimal operation.
