Raypak Avia 018051 P-R404A-EP-N Model R404A Pool & Spa Heater Propane 399 MBTUH 120/240V with NiTek Heat Exchanger
Industry-First Technology
Managing your pool heater has never been easier or smarter. AVIA is built with an innovative Wi-Fi enabled control system that allows you to manage your pool heater with one accessory through the Raymote app – so no need for a separate control panel to manage your pool heater.
With Raypak’s industry-first technology, NiTek, this AVIA HD is 300% more erosion resistant than copper, and 200% more than cupronickel.
Overview
The Raypak Avia series is positioned as a modern, digitally controlled pool and spa heater that integrates smart controls and durable materials for residential use. The Avia platform emphasizes Wi‑Fi enabled control through Remote and a touchscreen interface, allowing remote management of temperature and system settings from a single accessory.

Features and Technology
NiTek Heat Exchanger: The Avia R404A uses Raypak’s NiTek heat‑exchanger technology, which is designed to reduce scale formation and increase corrosion resistance by using higher nickel content compared with traditional cupronickel exchangers; Raypak cites improved longevity and modest efficiency gains from this material choice. Digital Controls and Connectivity: The heater includes an integrated digital control system with Wi‑Fi capability (Remote app compatibility) and a touchscreen interface, removing the need for separate control panels and enabling ecosystem management from the heater itself.
Performance and Efficiency
Raypak markets the Avia line as energy efficient and compliant with certain regional standards (e.g., California Title 24 guidance for pool heating when configured appropriately). The NiTek exchanger contributes to reduced scaling and stable thermal transfer, which supports consistent performance over time and can lower maintenance frequency. Dealer listings note the model is suitable for residential pools and spas requiring high‑output heating up to the 399k BTU range
