Premium Performance Meets Rugged Reliability

The Rheem P-M266A-EN-X CuNi Digital Heater delivers exceptional heating performance for in-ground pools and spas, engineered with cutting-edge features and long-lasting materials. Designed for durability and smart operation, this model features a cupronickel heat exchanger, polymer headers, and advanced digital controls – making it the ideal choice for both residential and commercial environments.

Key Features:

✅ Electronic Ignition System
Intermittent spark ignition only activates the pilot when there’s a call for heat—maximizing gas efficiency and safety.

✅ Microprocessor-Based Thermostat
Set your desired pool or spa temperature at the push of a button, with a bright digital display showing real-time readings.

✅ Built-in Diagnostics
Troubleshoot instantly with an integrated diagnostic system that pinpoints issues directly on the digital screen.

✅ Remote-Ready
Easily integrates with most major pool automation systems using standard two- or three-wire remotes.

✅ All-Weather Design
A wind-resistant, low-profile design keeps performance consistent in harsh outdoor conditions, from rain to snow.

✅ Corrosion-Resistant Cabinet
The Polytuff powder-coated metal housing undergoes a 7-stage wash system for superior adhesion, and uses galvanized metal underneath for long-term rust protection.

✅ Cupronickel Heat Exchanger
Engineered for harsh water conditions—cupronickel resists corrosion and scale buildup better than copper, ensuring long-term efficiency and reliability.

✅ Stainless Steel Tube Sheet + Polymer Headers
A fully non-ferrous waterway protects against internal rust and staining, extending life and keeping water clean.

✅ High Flow Compatibility
An internal automatic bypass allows up to 125 GPM water flow with minimal pressure drop—perfect for high-performance systems.

✅ CPVC 2" Slip-Fit Connections
Standard plumbing connections simplify installation and ensure a tight, secure fit.

✅ Fire Tile Combustion Chamber
The ceramic fiber chamber optimizes heat transfer while keeping the cabinet cool—no external heat sinks needed.

✅ Fuel-Efficient Performance
Exceeds federal and state energy efficiency standards, lowering utility costs while delivering maximum BTU output.

Perfect For:

• In-ground pools and spas

• Residential or commercial installations
