Rheem Water Heater Parts

When a Rheem tank or tankless water heater stops working properly, the fix is often a single part rather than a new heater. This collection gathers Rheem-brand replacement parts listed under Rheem part numbers, many of them in the SP series, so you can match the number on the old part or in the unit's parts list.

For gas tank heaters you will find gas control thermostats, combination gas control kits, burner assemblies, pilot and igniter assemblies, hot surface igniters, ignition controls and vent hoods. Electric models are covered with screw-in heating elements in several voltages and wattages, electric water heater thermostats and conversion kit assemblies. Dip tubes and anode rods are listed for tank maintenance, and tankless owners will find flame rods, controller kits, cable kits, inlet water filters, recirculation pump kits and concentric vent components for RTG and RTGH models.

Always confirm the model and serial number on the rating plate before ordering, because elements, controls and vent parts are model-specific, and leave gas control and burner work to a qualified technician. Browse the full Rheem lineup, or narrow it down to elements and conversion kits or dip tubes and anode rods.
