    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 Raypak Digital 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.

    built raypak tough

    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 connections

    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 Digital running efficiently and keeps the outside jacket cool. By using this space-age material the Raypak Digital 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 Raypak Digital is tested by CSA to the ANSI Z21.56 standard.

    Digital Controls

    Microprocessor Controlled Thermostat
    The Rapak Digital gas heater comes with a microprocessor based thermostat control. This control allows you to set your pool or spa temperature precisely at your favorite setting just by pressing an up or down temperature control button. The Digital display gives you a constant read out of your pool water temperature. Just set it, and forget it! Truly simple.

    digital controls

    Self Diagnostic
    Troubleshooting a gas heater has never been easier. The 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
    The 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.

    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)
