Protect the environment as you add value
Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless heaters to reduce energy consumption and CO2 emissions. That keeps exhaust temperatures very low — so low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.
