The Raypak 018051 AVIA HD P-R404A-EP-N Propane Pool & Spa Heater upgrades Raypak's AVIA platform with a NiTek heat exchanger for extra protection in demanding water chemistry environments, delivering a 399,000 BTU input for large pools that need fast recovery. Built-in Wi-Fi and onboard digital controls give owners full remote access via the Raymote app, and the unit is rated for elevations up to 4,500 feet. The NiTek exchanger is designed to hold up to saltwater systems and challenging water balance better than standard copper construction.
Even with its high 399,000 BTU output, the AVIA HD installs on a standard 2' x 2' equipment pad and can be rotated on three sides for flexible pad placement. The straight-tube heat exchanger design keeps the unit highly serviceable, and the included ProTek Shield replaceable module adds another layer of protection against galvanic corrosion over the life of the heater.
Digital direct spark ignition eliminates the standing pilot, cutting standby propane use and improving safety. The heater is SCAQMD Low NOx certified, California Title 24 compliant, and design-certified to ANSI Z21.56 / CSA 4.7, the current national standard for gas-fired pool and spa heaters.
