The Raypak P-R266A-MP-C features a classic Millivolt ignition system, which means it requires no external electricity to operate. By using a standing pilot light and a thermopile to generate its own millivolt current, this heater is the perfect solution for remote properties, rural estates, or equipment pads where running electrical conduit is impractical or impossible.

With a robust 266,000 BTU output, the 009201 delivers enough power to heat mid-to-large sized residential pools while maintaining the "set-it-and-forget-it" simplicity that has made Raypak Millivolt heaters legendary.

Features

No Electricity Required: The Millivolt system generates its own power from the heat of the pilot flame. This makes it immune to power outages and surges, ensuring your pool stays warm even if the main power grid goes down.

Simple Analog Dial Control: No complex digital menus or touchscreens to fail. The straightforward mechanical thermostat allows you to set your temperature with a simple turn of a dial—perfect for users who value ease of use.

Standard Copper Heat Exchanger: Built with integral copper fin tubes for maximum heat transfer and efficiency. The single-piece header design ensures smooth water flow and reduces the risk of internal leaks.

Corrosion-Resistant Polymer Headers: Equipped with glass-reinforced polymer headers that resist the corrosive effects of pool chemicals and provide a lightweight, durable alternative to metal headers.

PolyFlo Integrated Bypass: Automatically balances the water flow through the heat exchanger to prevent condensation and scale buildup, protecting the heater's internal components from premature wear.

ProTek Shieldâ„¢ Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from galvanic corrosion (electrolysis), a critical feature for modern pool maintenance.

Wind-Resistant Design: The low-profile cabinet is engineered to protect the pilot light and burner from downdrafts and crosswinds, ensuring reliable performance in exposed outdoor environments.

Equipped with an intelligent control system that can easily be tied into an existing remote system, our heater also features a microprocessor-controlled thermostat for setting the perfect temperature for your pool or spa.

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.
