The Raypak P-R406A-EP-C is the most powerful residential propane heater in the Raypak lineup, designed to provide lightning-fast heat-up times for large inground pools and luxury spa combinations where natural gas is unavailable. With a massive 406,000 BTU output, this heater is the gold standard for homeowners who want their pool ready at a moment's notice, regardless of the body of water's size or the ambient air temperature.

The 009227 model combines commercial-grade heating capacity with a sophisticated digital control system, making it the premier choice for large-scale rural estates, off-grid luxury projects, and high-end backyard retreats.

Features

Unrivaled Propane Heating Speed: With 406,000 BTUs of raw power, this unit can raise pool temperatures significantly faster than smaller models. It is the ideal choice for "on-demand" heating of large attached spas, even in the dead of winter, ensuring you never have to wait long for a soak.

Microprocessor-Controlled Thermostat: The intuitive digital display allows you to set your pool and spa temperatures independently to within one degree. The system also features constant self-diagnostics to alert you to any operational issues, ensuring the heater is always running at peak efficiency.

Fuel-Efficient Electronic Ignition: Features a robust "spark-to-pilot" ignition system that only lights when there is a call for heat. For propane users, this is a critical benefit as it eliminates the gas waste of a standing pilot light and prevents blow-outs in high-wind conditions.

Standard Copper Heat Exchanger: Built with high-quality integral copper fin tubes, this heat exchanger provides maximum heat transfer and 82% thermal efficiency. The single-piece header design ensures smooth water flow and minimizes the risk of internal leaks.

PolyFlo Integrated Bypass: Raypak’s patented bypass design balances the water flow through the heat exchanger automatically. This prevents condensation and scale buildup, protecting the heater's internal components from premature wear.

ProTek Shield Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), which is a leading cause of heater failure in modern chemically treated pools.

Non-Corrosive Cabinet Construction: The heater is housed in a polyester-coated, galvanized steel cabinet built to resist rust and UV fading. Its wind-resistant design ensures the burner stays functional even in exposed or harsh outdoor environments.

Notes

Professional Setup Required: Due to its high BTU rating, this propane heater requires precise gas line sizing and a high-capacity propane tank/regulator setup. It must be installed by a licensed HVAC or pool professional to ensure safety and to validate the manufacturer's warranty.
