Balboa 26-0071-DS-5S-K 15″ Universal Dual Sensor Flow Thru Heater Assembly 4.0kW

26‑0071‑DS‑5S‑K is a 15″ universal 4.0 kW dual‑sensor flow‑thru heater assembly used on Balboa and HydroQuip spa packs.

This heater is a universal retrofit for many Balboa and HydroQuip packs that use dual M7 sensors. Key characteristics:

• 4.0 kW @ 240V

• 15″ stainless flow‑thru tube

• Dual M7 sensor ports (temp + hi‑limit)

• 2″ unions (≈3″ OD)

• Straight‑through plumbing

• Works with BP‑series, VS/EL‑series, and HydroQuip packs that accept external M7 heaters

This is the correct heater when replacing a failed Balboa /HydroQuip 4.0 kW tube with dual sensors.
