The Raypak 156A (014786) is a 150,000 BTU liquid propane pool gas heater for above-ground and in-ground pools at elevations from sea level to 1,999 feet. It uses Raypak's AFT digital controls, a copper fin-tube heat exchanger, and a PolyTuf powder-coated galvanized steel cabinet. A stationary propane tank and licensed gas contractor are required for installation.
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 014786 - 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 to 8,000 gallons |
A solar cover when the pool is not in use substantially reduces heat loss and propane consumption.
Raypak 156A 014786 - 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, eliminating standing-pilot propane waste between cycles.
The copper integral-fin-tube heat exchanger uses single-piece extruded copper construction with stainless steel tube sheets. Polymer headers prevent rust staining on pool surfaces. The Unitherm Governor keeps heat exchanger 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 adds replaceable sacrificial corrosion protection at the exchanger inlet, rated for chlorinated and salt water pools.
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. Small BBQ-size cylinders cannot power this heater — a stationary tank of 100 gallons or larger (250 gallons commonly recommended) and a two-stage regulator are required.

Frequently Asked Questions - Raypak 156A Propane Pool Gas Heater 014786
What pool size is the Raypak 156A 014786 right for?
In warm climates, up to approximately 10,000 gallons. In cooler climates or pools with high evaporation, shade, or wind exposure, 6,000 to 8,000 gallons for comfortable recovery times. Both above-ground and in-ground installations are supported.
What propane tank do I need?
Standard 20-lb BBQ cylinders cannot sustain the pressure or flow required. A stationary tank of at least 100 gallons is needed; 250 gallons is commonly recommended when the pool heater is the primary propane load. A two-stage regulator between tank and heater is required. Your licensed propane contractor must size the tank, regulator, and supply line for your site.
What are the electrical requirements?
The 014786 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 heater?
Yes. The 156A cannot cool pool water. Gas heaters deliver fast, on-demand heating regardless of ambient air temperature, making them well suited to climates or seasons where heat pumps lose efficiency.
How does the propane 014786 compare to the natural gas 014784?
Both produce 150,000 BTU/hr at 82% efficiency with identical AFT digital 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. Choose based on which fuel is available at your site. For propane above 1,999 ft, see the 014787 (2,000–3,999 ft) or 014788 (4,000–6,999 ft).
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.
