About this heater

This HydroQuip Rite Fit 3.0KW 230V flow-through heater assembly delivers reliable heating performance for residential spas and hot tubs. The 27-J0413-4S-K model features a durable Incoloy heating element rated at 3000 watts and 230 volts, designed to provide consistent water temperature control in standard spa circulation systems. This genuine HydroQuip OEM replacement part ensures proper fit and performance when your existing heater fails due to element burnout or housing damage.

At Bubbles Supply, we guarantee this heater assembly will fit exactly as your original equipment, backed by our comprehensive 1-year warranty and same-day shipping on in-stock orders. The flow-through design integrates seamlessly with most HydroQuip control systems, making this an ideal solution for restoring your spa's heating capability. Verify your existing heater's part number and electrical specifications before installation to ensure compatibility with your spa's electrical system and plumbing configuration.

Before you buy — quick checklist

  • Confirm your existing heater's part number matches 27-J0413-4S-K before ordering
  • Verify your spa is wired for 230V — do not install on a 120V system
  • Check that your HydroQuip control system is compatible with a 3.0KW heater element
  • Inspect union connections and plumbing fittings on your existing heater before disassembly — confirm this unit's unions match your plumbing
  • Test your hi-limit sensor and pressure switch before replacing the heater — a failed sensor is often the actual cause of heater faults
  • Shut off power at the breaker and verify zero voltage before touching any wiring

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
