The ultimate in energy efficiency

Navien condensing technology provides up to 0.99 Energy Factor. These extremely efficient and eco-friendly units provide extra energy savings over traditional tank and non-condensing tankless water heaters.

A cooler way to save energy

Navien’s primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless heaters. That keeps exhaust temperatures very low—so low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.

Navien condensing tankless water heaters are ideal for replacement of less efficient tank systems as well as for new construction.
