Protect the Environment as You Heat Your Home

 
Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers 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.
