{"title":"Rinnai Parts","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eA tankless water heater that suddenly produces lukewarm showers is rarely the boiler itself. More often, it is a fan motor that has lost speed, a vent screen blocked by debris, a flame sensor reading dirty, or a control board that stopped registering inputs. Rinnai parts handle every one of these scenarios at the component level, which is the difference between a 90-minute repair and a $3,000 replacement quote. We stock genuine Rinnai tankless parts, Rinnai water heater parts, and Rinnai heater parts across the full SENSEI series, RU and RUR cover assemblies, V series furnaces, and the venting and isolation hardware most installers run through routinely.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis collection covers Rinnai water heater parts in three broad categories. Combustion and airflow components include fan motor assemblies for RL94e, RL75e, and VC indoor tankless heaters, vent screens for both intake and 3-inch combustion air, and air inlet assemblies. Venting and termination hardware covers non-condensing roof termination kits, concentric vertical termination kits, starter adapters, and pipe cover enclosures for SENSEI SE+ models. Service and conversion components include LP-to-NG conversion kits for SENSEI RU160e tankless units, Matsui isolation valve kits, retrofit door replacement kits for V53De units, and a recirculation pump kit that enables Rinnai Circ-Logic technology (WiFi and app control require a separately sold wireless module).
