The Raypak P-R336A-EN-X is a professional-grade heating solution designed for large residential pools and commercial-scale spas. This 336,000 BTU natural gas model is upgraded with a high-performance Cupro-Nickel heat exchanger, providing the highest level of durability against the damaging effects of saltwater systems, poor water chemistry, and high-velocity water flow.

The 014940 model ensures your large body of water reaches the perfect temperature quickly while providing the peace of mind that comes with premium, salt-ready internal components.

Features

Corrosion-Resistant Cupro-Nickel Heat Exchanger: Constructed from a robust copper-nickel alloy, this heat exchanger is specifically engineered to outlast standard copper versions. It offers superior resistance to erosion and chemical corrosion, making it the essential choice for pools equipped with salt-chlorine generators.

Large Capacity Heating Performance: With 336,000 BTUs of power, this heater provides the thermal lift necessary to warm large inground pools rapidly. It is the ideal "bridge" model for owners who want near-flagship performance with a slightly smaller footprint than 400K BTU units.

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 fast and simple.

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 on gas costs and preventing common pilot blow-outs in windy conditions.

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 thermal efficiency and protecting the heater's internal components.

ProTek Shield Technology: This innovative, replaceable module is designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), providing a critical second layer of defense for the unit's most vital parts.

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 coastal outdoor environments.

Flexible Installation

Whether upgrading your existing system or adding a new pool or spa to your home, the Raypak Digital Gas Pool and Spa Heater offers you flexible installation solutions.

Bonus: The self-adjusting burner compensates for gas pressure fluctuations, ensuring that the heater will always burn clean and safe.

What will it cost to heat your pool?

Fuel and electricity prices vary a lot by region, so put in your own rate from your last bill and get a number that's actually yours.

1 · Your pool
Water now 68°F
Temperature you want 84°F

You need to raise the water 16 degrees

2 · Your heater & rate
Set at the factory — you buy the version matching the fuel you have.

And what about month to month?

Warming the pool up is a one-off. Most of what you'll actually spend is holding that temperature — replacing the heat your pool loses to the air, day and night.

Keeping a solar cover on saves roughly $0.00 a month here — most of a heated pool's heat leaves by evaporation off an open surface, so a cover is the cheapest thing you can do to bring this figure down.

Warm-up figures are the physics with no heat loss. Your pool loses heat to evaporation, wind and cool air the whole time the heater runs, so those numbers are a floor, not a forecast. The real-world line adds a typical 25–50%.

Monthly figures are an estimate, and a rough one. They assume you hold your target around the clock for 30 days. Real heat loss swings a long way with wind, humidity and how much sun your pool gets — an exposed, windy yard can run well above these numbers and a sheltered sunny one below. Treat them as a ballpark for comparing options, not a quote.

Warm-up uses gallons × 8.34 × degrees of rise. Monthly uses an estimated heat loss across your pool's surface area against the temperature difference with the air, at 82% thermal efficiency for gas. Pool presets assume 4 ft of water in a 52" wall and 3.5 ft in a 48" wall. Estimates only. Not sure of your pool volume or which heater fits? Get in touch.
