Product details

The Raypak AVIA P-R404A-EP-N is a 399,000 BTU propane gas pool and spa heater with low NOx emissions, built-in WiFi and Raypak's NiTek heat exchanger. It is the largest AVIA and the model to choose for a big pool or a pool and spa combination where the spa has to be hot quickly.

Built to last on the pad

The NiTek advanced heat exchanger uses HD NiTek tubing, and the ProTek Shield adds a further layer of protection for the exchanger. Together they are what Raypak points to for the AVIA's durability and long service life in pool and spa water.

Connected

WiFi is built in, so the heater joins your home network and can be monitored and adjusted from the Raypak app rather than at the pad.

Before you order

This is the propane model rated for 0 to 4,500 ft elevation; higher sites need the high altitude version, and natural gas sites need the NG model. Gas heaters must be installed by a qualified professional to local code, and this unit ships by freight on a pallet.

Questions and answers

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

Is the Raypak AVIA P-R404A-EP-N, 018051, natural gas or propane?
Propane. Raypak builds the AVIA for one fuel and sells the other as a separate model.
Does the Raypak AVIA 018051 have Wi-Fi built in?
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 018051 rated for?
Raypak's catalog lists the propane AVIA for 0 to 4,500 ft, and sells a high elevation kit, 018762F, for propane above that.
What is the heat exchanger on the AVIA P-R404A-EP-N?
Raypak's NiTek, nickel coated HD tubing, which is what the N at the end of the model number means. Raypak says it resists erosion better than copper or cupronickel, cuts scale formation and matches copper's thermal efficiency.
What warranty does Raypak give the AVIA 018051?
Three years on the whole heater, which Raypak's catalog gives for all residential replacements and new builds.
Where is the manual for the Raypak AVIA 018051?
