Raypak Avia 399K BTU Natural Gas Pool Heater - NiTek Heat Exchanger - P-R404A-EN-N | 018033

The AVIA 400 is a total reimagining of pool heating technology. Delivering a massive 399,000 BTU output, this unit provides lightning-fast heat-up times for the largest residential pools and luxury spa combinations.

The 018033 model features the revolutionary NiTek™ heat exchanger, which offers 300% more corrosion resistance than standard copper. Combined with integrated Wi-Fi and the ability to control your entire equipment pad from a smartphone, the AVIA is the ultimate "set-it-and-forget-it" heating solution.

Feaures

NiTek™ Shield Technology: The AVIA comes standard with a nickel-plated heat exchanger that is significantly more durable than traditional copper. It is specifically engineered to resist the corrosive effects of salt-chlorine generators and fluctuating water chemistry, extending the life of the heater.

Integrated Smart Automation: The AVIA features built-in Wi-Fi and the Raymote™ Mobile App. Not only can you control your pool temperature from anywhere in the world, but the AVIA can also manage your pool pump and lights, acting as a mini-automation hub for your backyard.

Unrivaled 399,000 BTU Power: This is the highest-capacity model in the AVIA series, designed for rapid temperature gains. It can heat a large spa in minutes and maintain a massive pool at a perfect temperature even in the dead of winter.

ProTek Shield™ Module: Features a replaceable module that protects the heat exchanger from the damaging effects of galvanic corrosion (electrolysis). This is a critical second layer of defense for saltwater pool owners.

Compact & Lightweight Design: Despite its massive power, the AVIA weighs under 140 lbs and features a small, square footprint. It is roughly half the weight of traditional 400K BTU heaters, making installation on tight equipment pads a breeze.

Intelligent Flow Monitoring: The AVIA is the only heater in its class with built-in "Protection Mode" that monitors water flow. If it detects a flow issue that could damage the unit, it will alert you via the app to prevent a costly repair.

High-Resolution Touchscreen: Features a large, intuitive digital display that works even with wet fingers. The "swing-out" control box allows for easy service access to all internal components.

Notes

Professional Setup Required: Due to its 399K BTU rating, this heater requires high-capacity gas line sizing (typically 1.25" to 1.5") and precise venting. To enable the smart automation features (controlling your pump/lights), additional sensors or wiring may be required during the initial professional installation.
