Our Verdict
For a straightforward combi swap at the best price with the longest heat-exchanger warranty, Navien is the value pick and our most-installed brand. If you want a boiler engineered and built in Burnaby — with the fastest local parts access in the province and a slightly higher peak efficiency on the V-Series — IBC is the homegrown choice, especially for heating-only and hydronic systems.
Choose Navien if:
- Lowest entry installed price of the two
- Widest combi lineup (NCB-E and high-output NCB-H)
- Industry-leading 15-year heat-exchanger warranty
- Same-day parts from multiple Metro Vancouver distributors
- Best for a standard combi heat-and-hot-water replacement
Choose IBC if:
- Designed and manufactured in Burnaby, BC — fastest local parts
- Up to 96% AFUE on the V-Series (highest of the two)
- BC-climate-tested engineering and V-10 touchscreen control
- Strong heating-only and commercial (HC) cascade lineup
- Best if you want Canadian-made and a hydronic / radiant system
