How It Works
Get an Endless Supply of Hot Water for Less
Conventional hot water heaters heat and store hot water 24/7. That constant heating and re-heating of water is an enormous waste of energy and money. A tankless water heating system is the energy-efficient way to meet all your hot water needs. Once a hot water faucet is turned on, cold water enters the tankless water heater system. It is then heated. When finished, your tankless systems returns to a ‘stand-by’ mode. You save energy by using it only when you need it.
Why We Use the Navien Condensing 98% Water Heater:
Built-In Circulation Pump & Buffer Tank
These two parts save precious water by recirculating water that would otherwise be lost. Together, they also eliminate the minimum-flow requirements of other systems, as well as the dreaded “cold-water sandwich!”
Automatic Water Leak Detection
Special software detects leaks, preventing damage to the water heater—or worse, a home or business!
What is “Condensing Technology?”
Imagine the condensation on a glass of ice water. This condensation is created from the incoming cold water cooling the hot gases inside the unit. Navien’s state-of-the-art, stainless-steel condensing heat exchanger then traps this condensation and uses it, making the whole process incredibly efficient and economical.
This condensation would normally escape through the vents in a conventional tankless water heater. With Navien’s cutting-edge technology, the condensation is put to work, providing you with the most efficient and economical hot water heater on the market today.
