OVERVIEW
The sleek and stylish Raypak Digital Gas Low NOx Pool and Spa Heater features innovative technology designed to keep your pool or spa at the perfect temperature for your enjoyment. Built to withstand various weather conditions, this modern pool and spa heater is the perfect solution for environments requiring efficiency, convenience and versatility. Whether upgrading your existing system or adding a new pool or spa to your home, our heater offers you flexible installation solutions. Thanks to a brilliant low-profile design, corrosion resistant cabinet made of galvanized metal, copper fin tube heat exchanger, and a bevy of advanced-engineered materials, enjoying your heater year round is a breeze.
 
Digital Controls
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.
 
Smart Design
One look will tell you that the Raypak is different! The look is contemporary. The design is advanced. And inside and out it's engineered to last. The attractive forest green and charcoal gray panels complement the latest pool and spa equipment designs. Raypak's original "pagoda top" design will keep the heater operating even in extreme wind conditions and downdrafts.
 
Polytuff Powder Coating
The Raypak 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 that gets powder coated goes through a 7-stage wash system making certain the powder paint has a perfect bond. Underneath the tough and 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 Header
The Raypak Digital incorporates the latest in header design technology. Raypak's state-of-the-art engineering department utilized the latest in 3-D computer aided design to engineer the part for optimal performance. Polymer resin headers prevent rust stains from harming your pools surface giving you years of trouble-free swimming pleasure
 
All Copper Fin Tube Heat Exchanger
All Raypak Digital gas heaters come standard with integral copper finned tube. This means that the fin tubing is made from one piece of extruded copper tube. Since the fins are integral to the tube, maximum heat transfer is attained. Every Raypak Digital has the same robust design tube bundle that we use in our large gas commercial boilers.
 
Stainless Steel Tube Sheet
Stainless steel tube sheets are used on all Raypak Digital heaters that use the Polymer resin headers. This allows for a completely nonferrous waterway leaving your pool truly rust-free.
 
CPVC 2" Water Connections
Standard with every Raypak Digital is a set of 2" slip fit CPVC water connections to make your installation secure and effortless.
 
Condensation Protection
Standard on all Raypak Digital models is Raypak's Unitherm Governor, which helps reduce condensation from low inlet water temperatures. The Unitherm Governor automatically regulates the water flow to help keep the water temperature in the heat exchanger above 105 Degree F. Both water temperature and water flow rate are controlled to eliminate condensation, sooting, and scale buildup that can shorten heater life.
 
High Flow Rates
No need to worry about large pumps or high flow systems. The Raypak Digital comes with an automatic bypass built into the header. You'll find that the Raypak Digital delivers the industry's lowest pressure drop and highest water flow rate - up to 125 gallons per minute - exceeding the maximum recommended for 2" plumbing systems. More hot water moves through faster and more efficiently.
 
Fuel Efficient
Efficient? You bet. Energy-smart Raypak heaters consistently achieve the highest efficiency ratings and the Raypak Digital is no exception. It exceeds all federal and state standards.
 
Burner Tray
Every Raypak Digital burner tray is built to last. From the stainless steel burners to the aluminized metal used in the heat sensitive areas. In the event that anything should happen to your burners they can be quickly and easily serviced. One more reason why the Raypak Digital is made to take the work load year after year.
 
Fire Tile
A ceramic fiber combustion box keeps your Raypak Digital running efficiently and keeps 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.

Love this heater so far.
Went through 2 Pentair 400k btu heaters in 10 years so I thought I would try a Raypak. It's twice the size of a Pentair so make sure it will fit. So far I love it. It's very quiet and seams efficient.

Last one lasted 13 years.
Purchased this to replace a 13 year old unit that was done-in by hurricane Harvey. Lots of DIY after the flood, this was no different, everything fit perfectly, and it started up without issue. BTW, it was delivered to Texas in less than a week.

THIS IS THE SH.T!
I love my Raypac Heater. I had the original version in 1989/. She finally died on me and I bought this version, I am so happy with how fast this mother works.

I am only giving four stars at this time, since we’ve only used it once since we installed it. So far so good
