The Raypak Digital

Built Raypak tough.
Built to last.


Raypak gas heaters will effortlessly raise your pool's temperature well into the 80-90 degree range, and/or your spa to 104 degrees, generate a rapid heat-up, plus ensure a constant temperature regardless of weather conditions.

In addition to warming the water, the swimming season can be extended in cooler climates by as much as 50 percent. Raypak units require little to no maintenance, and typically last 5 to 10 years, or more.



Available in Natural Gas or Liquid Propane

Raypak Digital Standard Features for all models
Wind Resistant

Built-in Wind Resistant Design
The Raypak Digital has the best outdoor design in the market today. With over 50 years in designing and building gas heaters, Raypak has put all that experience into its newest design. No need for fans to combat drafting problems, the Raypak Digital was designed for 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: falling leaves, wind, airborne debris, rain, downdrafts, updrafts, sleet, snow, etc. In fact it is so efficiently designed it ensures uninterrupted heating performance regardless of all but the most extreme weather conditions.


. Smart Design
One look will tell you that the Raypak Digital 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 Raypak Digital operating even in extreme wind conditions and downdrafts.

. Polytuff Powder Coating
The Raypak Digital 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.


Non-Corrosive Waterways

. 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.

. Unitherm Governor
Raypak engineered the Unitherm Governor specifically for pool heater applications, regulating low temperature incoming water, to help reduce condensation. The Unitherm Governor 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 buildup that can shorten heater life.

. Automatic Bypass
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.

. 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.

. 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.

Combustion Chamber

. 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 running efficiently and keeps the outside jacket cool. By using this space-age material the Raypak won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.


. ISO 9001
Raypak is proud to be an ISO 9001 registered manufacturing plant. One more reason why Raypak is number one in the heater industry today.

. End-of-Line Test
Every Raypak gas pool heater is plumbed and test fired before it is put in the carton. This ensures that your heater will fire right out of the box and continue to give you years of trouble-free operation.

. Quality Checkpoints
The Raypak assembly process includes 6 final assembly quality checkpoints that help to ensure that each and every Raypak Digital is built correctly, and built to last.

. CSA Certified
All of Raypaks products are CSA certified. The R series are tested by CSA to the ANSI Z21.56 standard.

. Self Diagnostic
Troubleshooting a gas heater has never been easier. Raypak Digital has on-board diagnostic controls that let the user and the service professional know what is going on with the heater at all times. In the event that you would ever have a problem with the heater, the digital display will show where the problem is in the control circuit. It's like having a service technician built into every heater!

. Remote Compatible
Raypak Digital is compatible with most major pool control and remote systems on the market today. Any two-wire or three-wire remote can connect to the Raypak Digital and be integrated into the pool control system of your choice.

. Electronic Ignition
Raypak Digital heaters come standard with intermittent spark ignition pilot safety controls. What this means is that the pilot only comes on when there is a call for heat. This is a more energy efficient way to control you heaters gas usage by not having a standing pilot. Raypak has been using the same reliable electronic pilot ignition design for over 20 years.


. Use in high wind areas requires a High Wind Stack.
. Indoor installation requires Indoor Draft Hood.

• How to Choose the Right Size Heater:
• Proper heater size is based on the time required to heat pool or spa.
• If water is heated for each intended use, energy-saving rapid
• heating may be appropriate.
• If water is gradually heated to the desired temperature and then
• maintained at that temperature, a smaller heater may be acceptable.

Determine proper heater size using the following formula:
_____ desired water temperature (ºF)
_____ average air temperature (ºF)
_____ required temperature rise (ºF)
_____ req. hrs. to heat pool/spa to desired water temp.
_____ required temperature rise per hour (ºF)
