Raypak Millivolt 266K BTU Natural Gas Pool Heater - Copper - P-R266A-MN-C | 009193

The Raypak P-R266A-MN-C features a classic Millivolt ignition system, meaning it requires no external electricity to operate. By using a standing pilot light and a thermopile to generate its own small electrical current, this heater is the perfect solution for remote equipment pads, areas with frequent power outages, or simple installations where running electrical conduit is impractical.

With a robust 266,000 BTU output, the 009193 provides the heating power needed for mid-to-large sized residential pools, combining old-school reliability with modern materials.

Features

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

Simple Analog Dial Control: Features a straightforward mechanical thermostat. There are no digital screens to fail or complex menus to navigate—just turn the dial to your desired temperature for a "set-it-and-forget-it" experience.

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 pilot and burner stay functional even in exposed or rural outdoor environments.

Reliable Standing Pilot: While it uses a small amount of gas to keep the pilot lit, the standing pilot design is legendary for its simplicity and ease of service compared to complex electronic ignition boards.

Notes

Professional Setup Required: Because this unit utilizes a standing pilot and gas valves, it must be installed by a licensed HVAC or pool professional. Proper gas line sizing and adequate venting are critical for safe operation.
