Raypak's 337 Digital LowNox Emission units use combustion control to minimize levels of nitrogen oxides (NOx). The units meet emissions standards in all Low NOx areas, from Los Angeles (SCAQMD Rule 1146.2 certified) through the San Joaquin Valley (SJAPCD Rule 4308), and any other areas applying the stringent SCAQMD standard - the "Gold Standard" of emissions regulations - to residential pool heaters


ProTek Shield
New for 2021 Models, ProTek Shield is a cutting-edge module that protects the heat exchanger and extends the life of your Raypak Digital Gas Pool and Spa Heater. Rest, soak or swim knowing that your pool heater investment can be enjoyed even longer thanks to this innovative, patent-pending technology.

Excellent for use in chlorinated and salt water pools
Engineered to take the brunt of the corrosion that naturally occurs over time (erosion of the ProTek Shield means it’s working!)
Utilizes breakthrough patent pending technology
Compact design
Easy to replace, saving you time and money

Available for natural gas only

Digital Controls
provide solid-state reliability and accuracy and clear diagnostics. Setting it for the temperature you want is a snap...push a few buttons and walk away

PolyTuf Textured Powder Coating
The Raypak 337 Digital gas heater has a polyester-coated, non-corrosive cabinet that is more durable than solventborne- and waterborne-coated metal cabinets- Every piece of sheet metal goes through a 7-stage wash system, making certain the powder paint has a perfect bond. Underneath the tough, yet beautiful finish you will find galvanized metal that offers superior rust prevention and years of durable service

Wind-Resistant Design
No need for fans to combat drafting problems. This heater is designed to draft naturally in outdoor installations with its exclusive low-profile design--It is so thoughtfully and carefully designed it actually protects itself from the things that tend to stifle ordinary pool and spa heaters--It delivers uninterrupted heating performance regardless of falling leaves, wind, airborne debris, rain, downdrafts, updrafts, sleet, snow, etc

Polymer Headers
Polymer headers prevent rust stains from harming your pool’s surface, giving you years of trouble-free swimming pleasure

All-Copper-Fin-Tube Heat Exchanger
The fin tubes of the heat exchanger are each made from a single piece of extruded copper. This integral-fin design allows maximum heat transfer to be attained and maintained

Cupro-nickel is also available as an optional upgrade...These headers are specifically designed for the residential market...for commercial installations, use the ASME models.

Stainless Steel Tube Sheet
Stainless steel tube sheets are used on all Raypak gas heaters- This allows for a completely nonferrous waterway, leaving your pool truly rust-free

CPVC 2" Water Connections
Standard with every Raypak is a set of 2" slip-fit CPVC water connections to make your installation secure and effortless

Condensation Protection
The Unitherm Governor inside the header helps reduce condensation from low inlet water temperatures. It automatically regulates the water flow to help keep the water temperature in the heat exchanger above 105°F. Both water temperature and water flow rate are controlled to eliminate condensation, sooting, and scale build-up that can shorten heater life.

High Flow Rates
The Raypak gas heater comes with an automatic bypass built into the header. You'll find that the heater is capable of handling water flow at a rate up to 125 GPM.

Burner Tray
Every burner tray is built to last, from the stainless steel burners to the aluminized metal used in the heat sensitive areas. Innovative design allows for the easy removal of the tray and burners for servicing.

Fire Tile
A ceramic fiber combustion box keeps your heater running efficiently while keeping the outside jacket cool. By using this space-age material the heater won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.

Fuel-Efficient
Energy-smart Raypak heaters consistently achieve the highest efficiency ratings. They exceed all federal and state standards.
