The recirculation pump consideration
For installs that benefit from hot water recirculation (large homes with long runs to distant fixtures), Navien\'s built-in Comfort Flow pump saves the $200-400 separate pump install. Westinghouse WGRGH supports external recirculation but doesn\'t include the pump. Factor this into total install cost.
NaviLink vs no Wi-Fi
NaviLink lets you adjust setpoint, see fault history, and monitor operation from a mobile app. Some homeowners use this daily; others install once and never look at it again. If smart-control matters, Navien wins; if you don\'t care, Westinghouse value advantage applies.
Which to choose
- Value priority, basic install: Westinghouse WGRGH
- Want built-in recirculation + Wi-Fi: Navien NPE-A2
- Highest residential flow rate needed: Navien NPE-240A2 (11.2 GPM)
- Contractor prefers Navien: Navien
- Standard 2-3 bathroom install, cost matters: Westinghouse
Bottom line
Navien wins on built-in recirculation and Wi-Fi; Westinghouse wins on price. For installs that don\'t need recirculation or Wi-Fi, Westinghouse delivers comparable spec at $200-400 savings. For premium installs with recirculation and smart control desired, Navien is worth the premium.
