$722.00 $840.00


Onga Balboa 23910100 - 2391 Heated w/ Air Switch. Hot Spa Pump 1.25hp with 1.3kW (1300W) heater element. Made in the USA. Comes complete with unions and an in-built air switch. This pump will run approximately 5-8 jets. Originally were under the Onga brand, but now are Balboa. The pumps are the same.

Balboa spa bath pumps are one of the quietest in the industry. They offer maximum energy efficiency for lower operating costs, as well as no water retention for perfect hygiene, water resistant enclosures, and multiple levels of safety for your peace of mind.

The Balboa Pumps provide excellent hydraulic performance in a compact and extremely quiet design. Designed to circulate hot water in (whirlpool) spa baths, not spas, these pumps incorporate a special internal design to ensure the pump self drains eliminating the build up of unhygienic/stale water.

IMPORTANT: We are aware of some unscrupulous places selling bath pumps as standalone spa pumps. This is incorrect, and will lead to disappointment. 

  • These bath pumps are intended to help maintain temperature in a bath to roughly 36-38° and not to heat a bath from cold.
  • Spa bath pumps are designed for spa bathtub operation only and should not be used in chemically-treated water or permanently-filled spas.
  • For standalone permanently-filled spas, click here for retrofit kits.
