HydroQuip and Therm Products heater elements: Therm Products is a division of HydroQuip and supplies heating components for spa, hot tub, and hydrotherapy equipment. The line includes flow-through elements, titanium versions, epoxy-encapsulated configurations, and specialty flange and coil designs for servicing compatible heater assemblies. A replacement heating element is chosen by its actual electrical and mechanical specification—not by the brand of the spa alone. Before ordering, compare the original heater part number, power rating, voltage, element shape, mounting hardware, housing dimensions, and terminal arrangement with the replacement. That careful comparison helps avoid ordering an element that looks similar but cannot be installed or operated correctly.

The HydroQuip 3.0kW Epoxycast Flo-Thru Heater Element (12-E0104-K) is a 3.0kW replacement component in the 10-inch epoxycast flow-through family. The selected power rating represents a 3.0kW rating that needs to match the original equipment, including the heater control configuration and thermal safeguards. Epoxycast identifies a specific encapsulated element design within the flow-through family. Confirm that the original heater uses this construction and compare the mounting interface and available housing clearance; an ordinary flow-through item should not be assumed to substitute automatically. Its manufacturer reference is 12-E0104-K, which is the most reliable identifier when comparing the listing to service paperwork, a parts diagram, or the original heater assembly.

Material and electrical match: The supplier identifies Incoloy as the element material for this configuration. The alloy designation helps distinguish it from titanium versions that may share a similar power rating but have separate manufacturer part numbers. The structured supplier specification lists 230V, but the supplier headline also references 240V; verify the exact required voltage from the original element and current manufacturer documentation before publication or installation. Heating element replacement involves both the electrical system and a water-containing heater housing. The correct part must be installed with sound seals, suitable water-flow protection, and the mounting hardware required by the original equipment manufacturer. Do not select an element solely because its nominal output matches another product in the HydroQuip catalog.

Key Features and Replacement Considerations

  • Power-rating match: This part is identified as 3.0kW; a 3.0kW rating that needs to match the original equipment, including the heater control configuration and thermal safeguards.
  • Element form and fit: Epoxycast construction with 10-inch flow-through format. Measure the removed assembly and confirm mounting, bends, and terminal clearance.
  • Material and construction: Incoloy element construction according to the supplied product information. Evaluate material suitability together with the original heater design and exact replacement number.
  • Electrical and control checks: Supplier structured voltage is 230V; compare the heater/controller requirements and note any 230V-versus-240V labeling discrepancy in the source data.
  • Replacement identification: Order by HydroQuip part 12-E0104-K; no additional cross-reference supplied. Confirm the corresponding equipment model before completing a purchase.
