Product Description

Therm Products 5.5kW 240V Low-Flow Spa Heater Assembly HTAC32292A

Spa water that will not heat — or a heater that trips its high limit — usually traces back to a failed low-flow heater assembly. This Therm Products unit is the complete replacement: the U-shaped low-flow heater tube with its control box, built-in manual-reset high-limit switch, and pre-wired leads, ready to plumb into a low-flow circulation system and wire to the spa pack.

🚩 PRO TIP: Low-flow heaters only fire when circulation flow is proven — if a new heater still will not heat, check the circ pump and filter first. A clogged filter starves flow and the high limit will keep tripping even with a perfect heater.

FREQUENTLY ASKED QUESTIONS:

  • Is this the complete heater assembly? Yes — the heater tube, control box with high-limit switch, and wiring leads, exactly as shown in the photos. It is not just a bare element.
  • What systems does it fit? Low-flow spa circulation systems designed for this Laing trombone-style assembly — it crosses to the Sundance 6500-402 and 6500-403 and Jacuzzi 6698 heaters. Match the 5.5 kW / 240V rating and the tube configuration against your old heater before ordering.
  • Why does the heater have a reset button? The built-in high-limit switch shuts the heater down if water temperature in the tube runs too high, usually from low flow. Fix the flow problem, then press to reset.
