Raypak Digital 336K BTU Propane Pool Heater - Copper - P-R336A-EP-C | 009226

The Raypak P-R336A-EP-C is engineered to deliver serious thermal power to large residential pools and expansive pool/spa combinations where natural gas is not available. With a robust 336,000 BTU output, this liquid propane unit provides the rapid heat-up times necessary to overcome cold snaps and maintain a perfect swimming temperature year-round.

The 009226 model is the preferred choice for rural estates and luxury off-grid properties, combining a massive heating lift with the precise control of a modern digital interface.

Features

Rapid Heating Performance: Designed for larger bodies of water, the 336 model provides significantly more thermal power than standard mid-sized heaters. It is ideal for homeowners who want to heat a large pool quickly for weekend use or maintain a large attached spa at high temperatures.

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 your heater runs 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 eliminates the fuel waste associated with a standing pilot light and prevents common pilot blow-outs in windy 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 and maintaining high performance.

ProTek Shield Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), a critical feature for extending the life of the unit in modern pool environments.

Non-Corrosive Cabinet Construction: The unit 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 specific gas line sizing and a high-capacity propane tank/regulator configuration. It must be installed by a licensed HVAC or pool professional to ensure safety and to validate the manufacturer's warranty.
