The Raypak Avia HD 404 Low NOx Pool and Spa Heater (Model 018045) is a powerful natural gas unit built to provide efficient, high-capacity heating for residential and commercial pool systems alike. Outputting 399,000 BTU/h at 84% thermal efficiency, it brings water to temperature quickly and holds it there reliably. The cutting-edge NiTek heat exchanger technology delivers 300% greater erosion resistance than copper and 200% more than cupronickel, dramatically extending component life. Suitable for both indoor and outdoor setups with Category I & III venting compatibility, this heater offers true installation versatility. Wi-Fi connectivity through the Raymote platform enables remote monitoring and control, while its 135 lb chassis handles flows up to 125 GPM on standard 120/240VAC power.

Pool heater control has reached a new level of simplicity and intelligence. The AVIA features a groundbreaking Wi-Fi enabled control platform that lets you operate your heater through a single accessory via the Raymote app—eliminating the need for a dedicated external control panel.

Thanks to Raypak's pioneering NiTek technology, the AVIA HD delivers 300% more erosion resistance than copper, and 200% more than cupronickel.
