The Raypak 156A (014784, P-R156A-EN-C) is a 150,000 BTU natural gas pool heater for above-ground and in-ground pools at elevations from sea level to 4,999 feet. It uses Raypak's AFT digital controls, a copper fin-tube heat exchanger, polymer headers, and a PolyTuf powder-coated galvanized steel cabinet. This is the natural gas version rated for 0–4,999 ft.
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 156A 014784 - Pool Size by Climate
| Climate | Recommended Pool Size |
|---|---|
| Warm climate (moderate heat loss) | Up to 10,000 gallons |
| Cooler climate or high heat-loss pool | 6,000–8,000 gallons |
These figures reflect heat-up speed from a cold pool, not steady-state maintenance load. Above-ground and in-ground pools both supported. A solar cover significantly reduces heat loss and fuel use.
Raypak 156A 014784 - Key Features
The 156A uses Raypak's AFT digital control board with a microprocessor thermostat, LCD display, plain-text self-diagnostics, flame strength indicator, and run-time and cycle meter. Ignition is intermittent spark-to-pilot: the pilot fires only when the thermostat calls for heat, conserving gas between cycles.
The copper integral-fin-tube heat exchanger uses single-piece extruded copper construction with stainless steel tube sheets. Polymer (Capron resin) headers prevent rust staining on pool surfaces. The Unitherm Governor keeps inlet water above 105°F to prevent condensation and scale. An automatic internal bypass valve manages flow across varying pump speeds. The ProTek Shield module provides replaceable sacrificial corrosion protection at the exchanger inlet.
The low-profile pagoda-top cabinet drafts naturally without a fan. The unit ships factory test-fired with a 3-foot, 3-prong 120V power cord.

Frequently Asked Questions - Raypak 156A Natural Gas Pool Heater 014784
What pool size is the Raypak 156A 014784 designed for?
In warm climates, up to approximately 10,000 gallons. In cooler climates or pools with high evaporation, shade, or wind exposure, size down to 6,000 to 8,000 gallons for comfortable recovery times. Compatible with both above-ground and in-ground pools and spas.
What are the electrical requirements?
The 014784 ships factory-wired for 120 VAC with a 3-foot, 3-prong cord on a dedicated 15-amp circuit. The internal transformer can be field-rewired to 240V without additional parts. All electrical work must be performed by a licensed electrician per local code.
Is this a heat-only model?
Yes. The 156A cannot cool pool water. Gas heaters excel at 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 natural gas 014784 compare to the propane 014786?
Both deliver 150,000 BTU/hr at 82% efficiency with identical AFT controls, copper heat exchanger, and warranty terms. The natural gas 014784 is rated for 0 to 4,999 ft; the propane 014786 is rated for 0 to 1,999 ft only. Natural gas connects directly to a gas line; propane requires a stationary tank, two-stage regulator, and licensed gas contractor. Choose based on which fuel is available at your site.
How does the 156A compare to the R206A (009216)?
The 156A produces 150,000 BTU/hr and suits pools up to 10,000 gallons. The R206A (009216) produces 199,500 BTU/hr — roughly 33% more output — and suits pools up to 20,000 to 25,000 gallons. They are different cabinet platforms. If your pool is above 10,000 gallons, the R206A is the right step up.
What are the warranty terms?
Professional installation by a licensed contractor is required. Standard residential with registration and receipt: 2 years parts. New construction registered within 90 days with receipt: 3 years parts. Without registration: 1 year. Labor is not covered under residential warranty.
