The Raypak R266A (009225, P-R266A-EP-C) is a 266,000 BTU liquid propane pool heater for residential in-ground and above-ground pools at elevations from sea level to 2,000 feet. It is part of Raypak's full-size Digital series, rated at 82% thermal efficiency with the complete Digital control platform — LCD display, on-board diagnostics, flame strength indicator, on-board voltmeter, and run-time tracking. A stationary propane tank, two-stage regulator, and licensed gas contractor are required.
Gas heater sizing reflects recovery speed — how fast the heater raises pool temperature from cold — not steady-state energy demand. Cooler climates, shaded pools, or pools without a solar cover should size conservatively.
Raypak R266A 009225 - Pool Size by Climate
| Climate | Sizing Guidance |
|---|---|
| Warm climate (moderate heat loss) | Sizing depends on pool heat loss and recovery goals |
| Cooler climate or high heat-loss pool | Sizing depends on pool heat loss and recovery goals |
Sizing estimates should account for heat-up speed from a cold pool as well as steady-state heat loss. A solar cover between swims reduces heat loss and propane consumption at any pool size.
Raypak R266A 009225 - Key Features
The Digital control board provides a plain-English LCD readout of water temperature and target setpoint, on-board self-diagnostics in readable text, a flame strength indicator on every ignition event, a run-time and cycle counter for service scheduling, and an on-board voltmeter that confirms correct wiring at installation and monitors supply voltage during operation.
Ignition is intermittent spark-to-pilot: the pilot fires only when the thermostat calls for heat, conserving propane between cycles. A soft-opening gas valve prevents hard-start surges. The self-adjusting stainless steel burner compensates for propane supply pressure variation to maintain a stable, clean flame. Minimum propane supply pressure at the heater inlet is 11" W.C. dynamic; a two-stage regulator is required.
The copper integral-fin-tube heat exchanger uses single-piece extruded copper with stainless steel tube sheets. Capron resin polymer headers create a fully nonferrous waterway, preventing rust staining. The Unitherm Governor keeps inlet water above 105°F to suppress condensation and scale. The automatic internal bypass valve manages flow across varying pump speeds. The ProTek Shield module provides replaceable sacrificial corrosion protection at the exchanger inlet, compatible with chlorinated and salt water pools. Every unit ships factory test-fired.
Propane Supply Requirements
Standard 20-lb portable cylinders cannot sustain the inlet pressure or flow for a 266,000 BTU/hr load. A licensed propane contractor must determine the appropriate stationary tank size based on required flow, ambient temperature, and other appliances. The contractor must also size the regulator and supply line for the site. Gas connection is 3/4" NPT.

Frequently Asked Questions - Raypak R266A Propane Pool Heater 009225
What pool size is the R266A 009225 right for?
The R266A delivers 266,000 BTU/hr input. Pool volume alone does not determine heater size: surface area, climate, wind, cover use, and desired heat-up time also matter. Ask a qualified pool professional for a site-specific recommendation.
What propane tank and supply do I need?
Standard 20-lb portable cylinders cannot sustain the pressure or flow required for a 266,000 BTU/hr load. A licensed propane contractor must determine the appropriate stationary tank size. The heater requires a minimum dynamic supply pressure of 11" W.C. at the inlet and a two-stage regulator. Your licensed propane contractor must size the tank, regulator, and supply line for your site and seasonal conditions.
What are the electrical requirements?
The 009225 ships configured for 120 VAC, single-phase, and can be field-converted to 240 VAC without additional components. It operates on a standard 15-amp dedicated circuit. Conduit can enter from either the left or right side of the cabinet. All electrical work must be performed by a licensed electrician per local code.
Is this a heat-only model?
Yes. The R266A cannot cool pool water. Gas heaters deliver fast, on-demand heating regardless of ambient air temperature. If cooling is also needed, a heat pump with an integrated cooling mode is the appropriate addition.
How does the R266A compare to the smaller R206A (009224)?
The R266A provides 266,000 BTU/hr of input, approximately 33% more than the R206A at 199,500 BTU/hr. Both feature Raypak Digital controls and copper heat exchangers, but the R266A has a wider cabinet (23 inches versus 20 inches). A qualified installer should confirm pad clearance, gas supply capacity and plumbing before upgrading.
What are the warranty terms?
Professional installation by a licensed contractor is required. Standard residential with registration and receipt: consult Raypak's current written warranty for coverage, registration deadlines, labor exclusions and other requirements. Installation must follow local codes and manufacturer instructions.
