Our Verdict
Both are compact, modulating, Wi-Fi-capable condensing units that suit most Metro Vancouver homes. Navien edges ahead on BC market share, parts availability, and a longer 15-year heat-exchanger warranty, plus it offers a fire-tube heating-only option (NFB). Rinnai counters with its proven tankless heat-exchanger engineering, Control-R app, and an exceptionally compact footprint — a great fit for tight mechanical rooms.

- Larger BC installed base and parts network
- 15-year heat-exchanger warranty (vs 12)
- Fire-tube heating-only NFB option for hydronic systems
- Slightly lower entry installed price

- Control-R Wi-Fi and a very compact wall-mount footprint
- Strong M-Series combi for heat + DHW in one unit
- Field-convertible NG/LP flexibility
- Best for small-to-medium homes and tight spaces
