What is a Navien Tankless Water Heater?

A Navien tankless water heater is a high-efficiency on-demand system that heats water only when you need it—unlike traditional hot water tanks that constantly store and reheat water. This smart technology helps homeowners save on energy bills, maximize space, and never run out of hot water.

Navien is a market leader in condensing tankless water heaters. Their most popular models include the NPE-240A2 (condensing), the NPN-199U (non-condensing), and newer combi units that provide both space heating and hot water.

Whether you're renovating or replacing an old tank, a Navien tankless hot water heater is a reliable upgrade with long-term energy savings.

How Do Navien Tankless Systems Work?

Instead of storing hot water in a tank, Navien systems use a heat exchanger to instantly warm up water as it flows through the unit. This "on-demand" approach:

• Reduces standby energy losses

• Delivers a continuous stream of hot water

• Makes your hot water system more compact and efficient

Most homes in Edmonton that install a Navien tankless water heater also benefit from rebates due to the unit’s high UEF (Uniform Energy Factor) rating.
