BALBOA Inline Vacuum Whirlpool Heater– 12 Amp 120v 1.5kW

Keep every spa session invitingly warm with the BALBOA Inline Vacuum Whirlpool Heater. Delivering 1.5 kW of heat at 120V and 12 amps, this compact heater is designed to maintain a consistent, soothing temperature as you soak.

Smart, practical design meets reliable performance. Installed on the lower suction side of your pump, it tucks neatly into the spa cabinet while providing immediate warmth the moment you fire up the jets. The result is a spa experience that feels premium from start to finish.

Smart, pump-synced operation ensures the heater starts and stops in perfect harmony with jet activity. No manual tweaking mid-soak—your water stays cozy as you relax.

Precise warmth with a smart thermostat lets you set your ideal temperature and enjoy a stable bath, free from surprising temperature swings that disrupt the mood.

Energy-efficient, on-demand heating is activated by a vacuum switch. The heater powers up only when the tub is in use, delivering warmth when you need it and conserving energy when you don’t.

Durable, all-weather construction features a corrosion-resistant stainless steel housing built to withstand the humidity and chlorination of spa environments, ensuring long-lasting performance.

Hassle-free retrofit and broad compatibility with unions and plumbing fittings included means straightforward installation on compatible tubs. This inline heater can replace many private-labeled water heaters from leading tub manufacturers and OEMs, including Hydro-Quip, NuWhirl, CG AIR SYSTEMS, American Standard, Kohler, and more.

Compact footprint, simple integration with a 1.5" connection size fits standard spa plumbing without sacrificing cabinet space or maintenance access, helping you keep a clean, professional spa setup.
