Meet the NuWhirl HWTP120-1500N Tee Water Heater—an intentional upgrade crafted to elevate your Whirlpool bath with consistent warmth you can feel from the first dip. Engineered to integrate with NuWhirl systems and compatible third‑party whirlpools, this 1500‑watt heater smooths out temperature swings and adds thoughtful safety features, so you can soak longer without fiddling with controls.

Where it shines

• Steady heat from start to finish—no more hot-cold fluctuations. The HWTP120-1500N maintains a comfortable, constant bath temperature for relaxed, extended soaks.

• Flexible installation—choose between a T-shape or inline setup to fit your plumbing layout and space constraints.
• Built-in safety you can trust—a thermostat caps temperature at 104°F, with an automatic thermal cutoff at 118°F to protect both you and your tub components.
• Customizable power for your soak—adjustable from 650 to 1500 watts to match your preferred soak length and heat delivery.
• Easy wiring with a piggy-back cable—the included NEMA‑compliant piggy-back cable simplifies connections when adding additional electrical loads.
• Broad compatibility—works seamlessly with NuWhirl systems and compatible third‑party whirlpool setups, expanding options for upgrades or new builds.
• Proven reliability—cURus certified and engineered for robust performance, NuWhirl Mojave products are trusted for long-term value.

The HWTP120-1500N resolves this with automatic activation tied to your pump cycle, ensuring warmth kicks in exactly when you’re ready for a soak. The thermostat limit and thermal cutoff add peace of mind in everyday use, while the tee/inline options and included adapters remove installation guesswork, reducing setup time and compatibility headaches.

Practical tips for best results

• Pair with a tub pump that reliably cycles on with heat expectations to maximize automatic activation benefits.
• Position the heater to promote even heat distribution; the Tee connection is designed to streamline routing.
• Verify downstream wiring meets local codes and electrical requirements to ensure safe operation.
