Raypak Digital Propane Pool Heaters

Raypak Digital Propane Pool Heaters
Raypak Digital propane gas pool heaters are made by Rheem, one of the leaders in heater and boiler technology, since 1925. Unlike other LPG pool heaters available on the market, Raypak is the only brand which exclusively focuses on pool heaters; and does not also manufacture pumps, filters, cleaners and other pool equipment or accessories.

Raypak Digital pool heaters are well built and solidly constructed for ease of use, durability and service ease. Available for Propane or Natural gas fuels, with Atmospheric or Low Nox combustion. Also available in Digital or Millivolt models - Digital models have an LED screen with status and diagnostic controls, electronic ignition and thermostat. Millivolt heaters have a mechanical thermostat, on/off switch, and no digital interface.

Raypak Digital Natural Gas-Fired pool and spa heaters, models 206A-406A are not for use in Texas or California, or other areas which have mandated the use of Low emission gas pool heaters. Low Nox heaters such as Raypak Low NOx models 207A-407A, use fan assisted combustion and exhaust with fewer burners, to meet reduced emissions standards. Raypak Digital Millivolt models are also restricted for California installations.

    Energy-smart Raypak heaters consistently achieve the highest efficiency ratings. They exceed all federal and state standards.

    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.

    PolyTuf Textured Powder Coating

    The Raypak Natural gas pool 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 powder paint has a perfect bond. Underneath the tough, yet beautiful finish you will find galvanized metal that offers superior rust prevention and years of durable service.

    Polymer Headers

    Polymer headers prevent rust stains from harming your pool’s surface, giving you years of trouble-free swimming pleasure.

    CPVC 2" Water Connections

    Standard with every Raypak is a set of 2" slip-fit CPVC water connections to make your installation secure and effortless.

    High Flow Rates

    The Raypak gas heater comes with an automatic bypass built into the header. You'll find that the heater is capable of handling water flow at a rate up to 125 gpm.

    Heat Exchanger

    Condensation Protection

    The Unitherm Governor helps reduce condensation from low inlet water temperatures. It 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 build-up that can shorten heater life.

    Rust-Free Waterways

    The Raypak Digital Swimming Pool Heater, with polymer headers, is equipped with an integral copper finned-tube heat exchanger and stainless steel tube sheets. This unique construction guarantees rust-free operation, especially important when heating spas and smaller swimming pools. Even the smallest details such as the studs and nuts are made out of stainless steel. The Payoff? A swimming pool heater that will last year after year and can easily be serviced if the need should ever arise.


    Stainless Steel Burners

    Burner design is a critical component in any gas swimming pool heater. The stainless steel burner system used in the Raypak Digital is inherently forgiving and extremely robust. The burner is self-adjusting to compensate for gas pressure fluctuations, allowing the heater to always burn clean and safe.

    Burner Tray

    Every burner tray is built to last, from the stainless steel burners to the aluminized metal used in the heat sensitive areas. Innovative design allows for the easy removal of the tray and burners for servicing.

    Fire Tile

    A ceramic fiber combustion box keeps your heater running efficiently while keeping 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.

    Fan-Assisted Combustion

    Not all swimming pool heaters are made the same. The Raypak design uses a fan to provide cool, controlled combustion air to the burners. Other brands use a fan to pull hot flue gases through the heater. The Raypak design allows the heater to outperform all others during cold starts and provide longer component life.

    Pilot Ignition

    Raypak Digital swimming pool 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 your swimming pool heater's gas usage by not having a standard pilot. This is the most reliable and robust ignition system available, an industry-proven standard for over 20 years.

    The Difference is the Heat Exchangers.

    Stainless Steel Tube Sheet

    Stainless steel tube sheets are used on all Raypak heaters with the polymer headers. This allows for a completely nonferrous waterway, leaving your pool truly rust-free.

    All-Copper-Fin-Tube Heat Exchanger

    The fin tubes of the heat exchanger are each made from a single piece of extruded copper. This integral-fin design allows maximum heat transfer to be attained and maintained. Cupro-nickel is also available as an optional upgrade.

    Cupro-Nickel Fin Tube - (Optional)

    Raypak heaters are available with an optional cupro-nickel fin tube heat exchanger for added protection against aggressive water chemistry, which has been known to attack copper heat exchangers and cause premature failure. Cupro-nickel offers superior tolerance to bad water chemistry and increases erosion protection, thanks to a harder surface and wall that is approximately 50% thicker than our standard copper fin tube. When you're unsure of your ability to maintain the pool or spa water chemistry, a cupro-nickel heat exchanger is a cost-effective way to protect against premature failure.

    ASME Copper Fin tube - (Optional - Commercial)

    ASME stands for American Society of Mechanical Engineers, a non-profit group which sets many industrial and manufacturing standards. A pool heater that is made to ASME standard must perform to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the application can handle. Each and every ASME heat exchanger that goes into Raypak heater is certified by a state inspector to make sure it complies with ASME codes for pool heaters. Why ASME? Most local codes require that public pools, pools that are in condominiums, apartments, or other commercial applications, be ASME certified.

    The Raypak Digital ASME gas heater is equipped with .062" wall integral copper finned tubes. This tubing is approximately 50% larger in wall thickness than standard tubing, providing additional resistance to wear from chemical corrosion. Raypak also has an ASME version which incorporates a Cupro-Nickel heat exchanger for pool applications subject to more aggressive chemical treatment, such as you would find in a health club spa. Raypak has inspectors on-site daily performing certifications for our pool heater and commercial boiler production that may require ASME.

    Digital models only:

    Microprocessor-Controlled Thermostat

    The Raypak Digital gas heater features a microprocessor-based control center. This control allows you to set your pool or spa temperature precisely at your favorite setting just by pressing the up or down temperature control buttons.


    On-board diagnostic controls 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 indicate the source.


    Compatible with most major pool control and remote systems on the market today. Any two-wire or three-wire remote can connect to the heater 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 provides an energy-efficient way to control your natural gas usage by eliminating the need for a continuous pilot.

    Millivolt models only:

    Mechanical Thermostat

    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.

    Millivolt Controls

    No power source is required for the Raypak Millivolt heater. All operating electricity is supplied by the pilot thermocouple.

    Quality assurance:

    ISO 9001

    We are proud to be an ISO 9001 registered manufacturing plant. It’s one more reason why Raypak is number one in the gas heater industry today.

    End-of-Line Test

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

    Quality Check Points

    The Raypak assembly process includes six final assembly quality check points that help to ensure that every Raypak gas heater is built correctly, and built to last.


    All of Raypak’s natural gas pool heaters are CSA-certified and are tested by CSA to the ANSI Z21.56/CSA 4.7 standard.
