Description

The Raypak 407A Low NOx Digital Natural Gas Heater delivers high-performance pool heating with 399,000 BTU output, making it ideal for large residential pools and demanding pool environments.

This model features a cupronickel heat exchanger designed to provide superior corrosion resistance compared to standard copper exchangers. The CuNi material helps protect the heater from aggressive water chemistry, salt exposure, and high-flow conditions.

The #26 bronze header configuration enhances durability and long-term reliability, making the heater well suited for installations where stronger components are preferred.

A digital control interface allows easy temperature adjustments and system monitoring, while the Low NOx combustion system helps meet emissions regulations in controlled air quality regions.

Built with Raypak’s proven atmospheric burner design and rugged cabinet construction, the 407A heater provides dependable heating performance for residential and commercial-style pool systems.

Pro Tip

If your pool uses a salt chlorinator or experiences aggressive water chemistry, a cupronickel heat exchanger offers improved protection against corrosion and premature heat exchanger wear.

Installation Tips

Install on a level equipment pad with proper natural gas supply and ventilation clearances. Ensure plumbing connections match heater flow requirements and confirm electrical and automation compatibility before installation.
