Noritz is heavily searched for combination (combi) boilers that supply both domestic hot water and space heating, and replacement parts need to match the exact model to work correctly. The fastest way to avoid ordering the wrong gasket, sensor, ignitor, or control component is to start with the model information from the unit label.

SupplyHouse stocks Noritz replacement parts for supported models, including common service items like ignition components, sensors, filters, and heat exchanger gaskets.

Enter the model number exactly as printed on the manufacturer label. Matching the complete model number is the quickest way to narrow parts lists and avoid ordering the wrong gasket, filter, ignitor, or sensor.

Yes. Noritz parts are frequently model-specific, especially gaskets and heat exchanger-related components, so matching by model number matters before checkout.

Recheck the label for the exact model number format (including hyphens and suffixes). If results still don't populate, use the part request form on the page so the team can research the correct parts list.
