What warranty coverage does the Bosch ZWB 42-3 include if I register it?

If you register within 90 days of installation, the ZWB 42-3 receives a five-year limited warranty covering defects in workmanship or materials, with labor included in the first year. From years 6-10, the heat exchanger is covered against leaks, and from year 11 onwards, a pro-rated warranty applies based on the percentage table in the warranty document.
