Product details

The Raypak AVIA P-R404A-EN-N is a 399,000 BTU natural gas pool and spa heater with low NOx emissions and WiFi built in. Raypak part number 018045.

Built to last on the pad

The AVIA pairs the ProTek Shield with the NiTek advanced heat exchanger and its HD tubing. The point of both is durability: a heater that keeps performing season after season rather than one that needs an exchanger a few years in.

Where it can go

It is rated for 0 to 10,000 ft elevation, so one model covers sea level and mountain installations alike. Natural gas only; this is the N fuel version.

Shipping

Full size pool heaters ship by freight.

Questions and answers

What people ask about this product, answered by our pool techs.

Is the Raypak AVIA 404, P-R404A-EN-N, natural gas or propane?
Natural gas. The propane AVIA is a separate model.
What is NiTek on a Raypak AVIA?
Raypak's nickel coated heat exchanger tubing, fitted to its HD models, the ones whose model number ends in N. Raypak says it resists erosion better than copper or cupronickel, cuts scale formation and matches copper's thermal efficiency.
Is Wi-Fi built into the Raypak AVIA 404?
No. Wi-Fi is built in, and Raypak's Raymote app, which is free, controls and monitors the heater once it is on the home network.
What elevation is the Raypak AVIA 404 rated for?
Raypak's catalog lists the natural gas AVIA for 0 to 10,000 ft with no separate high altitude model. Its manual adds that the heater is CSA certified to 4,500 ft and operable to 10,000 ft on natural gas.
What warranty does Raypak give the AVIA 404?
Three years on the whole heater, which Raypak's catalog gives for all residential replacements and new builds.

Under Downloads on this page. It is Raypak's AVIA Installation and Operation Manual for models 264 and 404, part number 100-10000111.
