Raypak Digital 336K BTU Natural Gas Pool Heater - Copper - P-R336A-EN-C | 009218

The Raypak P-R336A-EN-C is engineered to deliver serious heating power, making it the ideal choice for large inground pools or pool/spa combinations that require rapid temperature gains. With a massive 336,000 BTU output, this heater ensures you spend less time waiting for the water to warm up and more time enjoying it, even when the ambient air temperature drops.

The 009218 model combines Raypak’s legendary "built-to-last" construction with a sophisticated digital control system and a high-efficiency copper heat exchanger, providing a reliable and user-friendly experience for the demanding pool owner.

Features

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, making troubleshooting simple and fast.

Reliable Electronic Ignition: Features a robust "spark-to-pilot" ignition system that only lights when there is a call for heat. This eliminates the need for a standing pilot light, saving you money on gas and preventing 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 efficiency. The single-piece header design ensures smooth water flow and minimizes the chance of leaks.

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

ProTek Shield Technology: This innovative, replaceable module is designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), which is a common cause of heater failure in modern pool environments.

Non-Corrosive Cabinet Design: The heater is housed in a polyester-coated, galvanized steel cabinet that is built to resist rust and UV damage. This wind-resistant design ensures the burner flame stays protected and functional even in harsh outdoor conditions.

Large Capacity Performance: Designed specifically for larger bodies of water, the 336 model provides the thermal lift necessary to maintain comfortable swimming temperatures in pools that smaller heaters would struggle to service.

Notes

Professional Setup Required: For safety and to maintain the manufacturer’s warranty, this gas heater must be installed by a licensed HVAC or pool professional. Proper gas line sizing (typically 1.25" or larger for this BTU rating) and adequate venting are critical for the safe and efficient operation of the 336 model.
