Technical Data
Simple Controls • Mechanical Thermostat The RP2100 Millivolt gas heater comes with one mechanical thermostat. This control allows you to set your pool or spa temperature precisely at your favorite setting. Just set it, and forget it! Truly simple.
Wind Resistant • Built-in Wind Resistant Design The RP2100 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 RP2100 design. No need for fans to combat drafting problems, the RP2100 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. Built Raypak tough. Built to last.

Cabinet • Smart Design One look will tell you that the Raypak RP2100 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 RP2100 operating even in extreme wind conditions and downdrafts.
• Polytuff Powder Coating The Raypak RP2100 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 RP2100 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 RP2100 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 RP2100 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 RP2100 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 RP2100 is a set of 2" slip fit CPVC water connections to make your installation secure and effortless.
• Condensation Protection Standard on all RP2100 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°. 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 RP2100 comes with an automatic bypass built into the header. You'll find that the RP2100 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 RP2100 is no exception. It exceeds all federal and state standards.
Combustion Chamber • Burner Tray Every RP2100 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 RP2100 is made to take the work load year after year.
• Fire Tile A ceramic fiber combustion box keeps your RP2100 running efficiently and keeps the outside jacket cool. By using this space-age material the RP2100 won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.
Quality • ISO 9001 Raypak is proud to be a 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 RP2100 is built correctly, and built to last.
• CSA Certified All of Raypak products are CSA certified. The RP2100 is tested by CSA to the ANSI Z21.56 standard.
