Raypak 016066 Hi Delta P-1262C Commercial Natural Gas Pool Heater, 1,260,000 BTU
Commercial heat. Cupro-Nickel core. Built tough.
The Raypak Hi Delta P-1262C (SKU PST-016066, MPN 016066) is a fan-assisted commercial pool and spa heater that delivers 1,260,000 BTU/hr of natural gas heat at 83.1% thermal efficiency. You get a Cupro-Nickel finned-tube heat exchanger paired with bronze headers, a patented sealed-combustion burner, and indoor/outdoor certification with multiple vertical and sidewall vent options. PST ships this heater factory-fresh from Raypak with the full manufacturer commercial warranty intact, ready for aquatic centers, hotels, apartment complexes, and large commercial pool and spa systems.
Sealed Burner, Complete Combustion
The Hi Delta P-1262C runs Raypak's patented sealed-combustion burner with an optimized air-gas pathway, so you get clean staged combustion and Low NOx compliance without sacrificing output. The fan-assisted design eliminates pilot outages from wind and downdrafts, and the staged firing pattern protects burner metal from thermal fatigue over thousands of heating cycles. You spend less on service calls and more time keeping a commercial pool at swim temperature, even on the coldest, windiest equipment-room days.
Cupro-Nickel Heat Exchanger
Raypak pairs a Cupro-Nickel finned-tube heat exchanger with bronze headers, so the high-flow water path resists the chloride pitting and galvanic corrosion that destroy copper-only cores on commercial salt and high-bather-load pools. The result is a heat exchanger built to ride out aggressive water chemistry at aquatic centers, hotels, and municipal pools. Combined with 83.1% thermal efficiency, the P-1262C drops gas bills versus older 78% commercial units while extending service life well past the typical copper-tube heater.
Versa IC Diagnostics
The on-board digital touch panel surfaces full diagnostics, fault history, and run-time data so your service tech finds problems in minutes instead of pulling panels. You get clear flame, ignition, and sensor codes plus venting guidance for vertical Category I and sidewall Category III installs up to 70 feet on room air with no extractor required. Cascade capability links up to eight units for staged commercial load, and ASME certification covers code-required commercial inspections out of the box.
Who It's For
Commercial Aquatic Centers
Sized for high-bather-load municipal and school aquatic centers that need 1.26M BTU of reliable, code-compliant heat with ASME certification and Low NOx compliance built in.
Hotels and Resort Pools
Cupro-Nickel construction stands up to chlorinated and salt-treated resort pools where heavy bather counts and aggressive water chemistry chew through copper-only heaters.
HOA and Apartment Complexes
Cascade up to eight Hi Delta units to scale total output for large multifamily pool and spa decks, and stage units to match seasonal demand without overshooting fuel cost.
Gyms, Schools, and Therapy Pools
Versa IC controls and full fault diagnostics keep maintenance staff on top of uptime in facilities where a cold therapy pool or lap pool means lost program revenue.

Cupro-Nickel finned tubes with bronze headers resist chloride pitting and galvanic corrosion in commercial water chemistry.
Versa IC Diagnostics
Digital touch panel surfaces fault history, run time, and ignition diagnostics for fast commercial service calls.
Low NOx Compliant
Meets all Low NOx air-quality regulations, including SCAQMD jurisdictions, with no field modifications required.
Indoor and Outdoor Rated
Category I vertical and Category III sidewall venting up to 70 ft on room air with no extractor required.
Cascade Up To 8 Units
Stage multiple Hi Delta heaters for large commercial loads without oversizing a single unit.
Installation Notice
This is a commercial gas-fired appliance. Gas piping, venting, and electrical hookup must be performed by a licensed gas technician and licensed electrician per NFPA 54 (National Fuel Gas Code), ANSI Z223.1, and local commercial mechanical code. Pool equipment bonding must follow NEC Article 680. Improper venting clearance, undersized gas supply, or missing bonding can cause carbon monoxide buildup, heater shutdowns, and will void Raypak's commercial warranty. ASME-certified units may require state or local boiler inspection at startup. Confirm jurisdictional requirements before installation.

Frequently Asked Questions
What is the difference between the P-1262C natural gas 016066 and the propane 016079, Cold Run 016089, or CSD-1 016066-K2?
All four are 1,260,000 BTU Hi Delta P-1262C heaters. The 016066 is the standard natural gas Low NOx model. The 016079 is the same heater factory-built for liquid propane. The 016089 adds Cold Run protection and Versa Control for cold-climate startups. The 016066-K1 adds the California (CAL) code package and the 016066-K2 adds the CSD-1 commercial boiler safety package required by some insurance carriers and jurisdictions. Pick the 016066 for standard commercial natural gas installs without CSD-1 or Cold Run requirements.
What pool size and bather load is the Hi Delta P-1262C rated for?
At 1,260,000 BTU input and 83.1% efficiency, the P-1262C delivers roughly 1,047,000 BTU/hr of useful heat. That is sized for large commercial pools in the 100,000 to 250,000 gallon range depending on temperature rise requirements, climate, and cover use. For higher loads, cascade up to eight Hi Delta units for staged output. Sizing should always be verified by a commercial pool design engineer using ASHRAE or industry heat-loss calculations.
What gas supply, venting, and clearances does this heater need?
The P-1262C is a Category I vertical-vent and Category III sidewall-vent appliance with up to 70 feet of sidewall venting on room air without an extractor. Gas supply must be sized to deliver full 1.26M BTU input at the required manifold pressure (verify on the data plate against your local pressure). Required clearances to combustibles, vent termination distances, and combustion air sizing must follow Raypak's installation manual and NFPA 54. A licensed commercial gas contractor should size the gas line and vent run for your specific install.
Why does this model use a Cupro-Nickel heat exchanger?
Commercial pools see high bather loads, heavy chemical demand, and often salt-chlorinated water, all of which create aggressive water chemistry that pits and corrodes pure copper. The Cupro-Nickel alloy resists chloride attack and galvanic corrosion far better than copper, dramatically extending heat-exchanger life in commercial duty. It is the right choice for any high-flow commercial pool, therapy pool, or salt-chlorinated installation.
Is the P-1262C ASME certified and do I need a boiler inspection?
Yes, the Hi Delta P-1262C heat exchanger is ASME H-stamped. Many states and municipalities require ASME-certified pool heaters at this BTU level for commercial pool installations, and some jurisdictions require state or local boiler inspection at startup. Check your local mechanical and boiler code before installation. PST can confirm the heater ships with the ASME documentation needed for inspection.
Can I install this heater myself?
No. This is a 1.26M BTU commercial gas-fired appliance and must be installed by a licensed commercial gas contractor per NFPA 54, with electrical and pool bonding per NEC Article 680. Many jurisdictions also require a mechanical permit and ASME boiler inspection. Self-installation voids Raypak's commercial warranty and creates real carbon-monoxide and combustion-air risks at this BTU level. PST recommends a licensed commercial pool mechanical contractor familiar with Raypak Hi Delta heaters.
Is the Raypak commercial warranty intact when I buy from PST Pool Supplies?
Yes. PST Pool Supplies is an authorized Raypak dealer, and every Hi Delta ships factory-sealed with the full Raypak commercial limited warranty. Keep your purchase documentation and have your licensed installer complete Raypak's commercial startup paperwork to lock in coverage. Commercial warranty terms differ from residential terms, review the owner's manual for parts and labor coverage windows.

Does what a small weed- eater would do it minutes versus an hour
Great product does exactly what was advertised to do.
I ordered the wrong part. Customer service was very helpful. I returned it and within the week my credit card was credited back. Excellent customer service policy.
There was a delay in shipping due to postal service. They sent another part right away.
New model 59303 works great, but too bad the last generation Balboa WiFi module 50350 became un-useable.
Exactly as advertised and super fast shipping and delivery
