Navien's primary condensing stainless steel heat exchangers are able to recover extra heat that would be lost in traditional tankless water heaters. Since all Navien's tankless water heaters are condensing tankless gas water heaters the exhaust temperature is very low. In fact the exhaust temperature is so low you are able to use PVC schedule 40 to vent the units in almost all applications. The use of PVC allows for significant installation cost savings compared to traditional tankless water heaters.
Navien's Condensing tankless water heaters are ideal for tank replacement providing an exceptional amount of cost savings during operation compared to traditional tank water heaters.
Unfortunately, old-fashioned tank heaters, as well as conventional tankless water heaters, emit harmful Nitrogen (NOx) and Carbon dioxide(CO2) directly into the air at a whopping 245°F-450°F! These harmful emissions damage both us and the environment in which we live.
With proven condensing tankless technology, Navien Tankless offers improved efficiency, reliable quality and durability,
together with the added assurance of a warranty. Just make the most of your energy.
