Before you buy — quick checklist

  • Confirm your existing heater part number matches 26-0814-7S-K before ordering
  • Verify your spa control system uses M7-type sensors — sensor compatibility is critical
  • Confirm your system operates on 230V, not 120V
  • Measure your existing heater tube length to confirm the 40-inch configuration fits your manifold
  • Check that your spa pack is a BP7 series HydroQuip control — this heater is not universal
  • Inspect heater unions and manifold end caps for damage before swapping the element
