The Raypak 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.
The millivolt ignition system does not require external power. It generates its' own current internally, with a small thermo couple driven by the constant pilot. The millivolt ignition system is not available in California for natural gas units.
PolyTuf Textured Powder Coating
The Raypak gas heater has a polyester-coated,non-corrosive cabinet that is more durable than solvent-borne and water-borne coated metal cabinets. Every piece of sheet metal goes through a 7-stage wash system. making certain the power paint has a perfect bond. Underneath the tough, yet beautiful finish you will galvanized metal that offers superior rust prevention and years of durable service.
No need for fans to combat drafting problems under normal conditions. 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.
ASME Pool Heaters
Raypak offers its complete line of residential gas heaters in an ASME version. You can select the Millivolt, Digital Electronic or Digital to be factory equipped with ASME waterways. Raypak has state inspectors on-site daily performing certifications for our pool and commercial boiler production that may require ASME. Being in the boiler business for over 50 years truly makes Raypak the leader for your commercial needs.
Some local codes require that public pools, pools that are in a condominium and apartment or other commercial application be ASME certified. ASME stands for American Society of Mechanical Engineers. They are a non-profit group which sets many industrial and manufacturing standards. A pool heater that is made to ASME standards will perform to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the appliance can handle. Each and every ASME heat exchanger that goes into a Raypak heater is certified by a state inspector to make sure it complies with the ASME code for that particular product.
Cast Iron Glass-lined Header
Raypak applies its years of commercial boiler experience to the design of its cast iron glass-lined headers. A metal header design allows for the higher working pressures required by ASME. All ASME headers are inspected upon arrival at Raypak and each lot (pour date) tested by an independent laboratory. Only after the material passes stress analysis and metal composition tests is it approved for use in an ASME unit.
All Copper Fin Tube Heat Exchanger
All Raypak ASME gas heaters come standard with .065" wall integral copper finned tubes. This tubing is over 50% thicker in wall thickness than standard tubing. Since the fins are integral to the tube, maximum heat transfer is attained. The fin tubing is made from one piece of extruded copper tube, not from separate fins attached to the copper tubes. Every RP2100 has the same robust design tube bundle that is used in Raypak's large gas commercial boilers. Built to last, built Raypak tough.
Optional Cupro-Nickel Fin Tube
Raypak Digital heaters can be ordered with cupro-nickel fin tube heat exchangers for added protection against aggressive water chemistry. Although rare, there are certain applications, like health club spa's, where copper is just not the best choice. Cupro-nickel offers superior tolerance to bad and fluctuating water chemistry, thanks to a harder surface and thicker walled fin tube.
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. These couplings screw into the 2" flanged header. You can also direct plumb your copper pipe into the flanged header.
Standard on all models is Raypak's Unitherm Governor, which is like an automatic bypass. The Unitherm Governor automatically regulates the water flow to help keep the water temperature in the heat exchanger above 105F.
Hi Flow Rates
No need to worry about large pumps or high flow systems. The RP2100 comes with an automatic bypass built into the header. The RP2100 can handle up to 125 GPM.
Raypak is proud to be a ISO 9001 registered manufacturing plant. One more reason why Raypak is number onein the heater industry today.
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.
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.
