Good to know before you buy
- Covers the original buyer only; coverage ends if the heater is sold or transferred.
- Keep your installation date and original receipt; Noritz needs both to start coverage.
- Buying from an unauthorized seller voids coverage.
- Coverage length depends on the model and whether it is used in a single-family home.
