The sleek and stylish Raypak Digital Gas Pool and Spa Heater features innovative technology designed to keep your pool or spa at the perfect temperature for your enjoyment. Built to withstand various weather conditions, this modern pool and spa heater is the perfect solution for environments requiring efficiency, convenience and versatility.
Thanks to a brilliant low-profile design, corrosion resistant cabinet made of galvanized metal, copper fin tube heat exchanger, and a bevy of advanced-engineered materials, enjoying your heater year round is a breeze.
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.
Microprocessor Controlled Thermostat
The Raypak 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.
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.
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 heater 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. Built Raypak tough. Built to last.
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 heater 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.
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.
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.
Condensation Protection
Standard on all Raypak Digital 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 Degree F. 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 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.
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.
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 heater won't retain residual heat after it is turned off, allowing it to be installed without the use of costly metal heat sinks.

what size of pool will this heat ?
A shopper on Sep 18, 2017
Can I place this heater on wood, concrete, aluminum, or
metal surface?
A shopper on Dec 20, 2017
How big of a pool is this good for?
A shopper on Nov 1, 2021
BEST ANSWER: I installed this particular heater in my 24 x 48 pool with a deep end (diving well). The pool holds 45,000 gallons of water. From cold it takes between 1-2 hours to raise temp 1 degree. When up to temp it has no problem holding constant temperature. Hope this helps.
Is this have to be hard wired or can you attach a plug?
A shopper on Apr 2, 2022
BEST ANSWER: Hard wired with a fireman’s switch on the timer so the heater shuts off and cools down before timer shuts off the filter
Does it come with propane tank??
Susan S on Jun 28, 2017
Is this Above ground pool compatable?
A shopper on Apr 2, 2022
BEST ANSWER: Absolutely! We bought this for our 15 X 30 above ground, oval pool last summer, and it quickly heated the water. Another amazing feature is how quiet it is! Once it ignites, you almost forget it is running!
How long can this heater run on a 100lb propane tank? The 100lb tanks hold 23 gallon of propane
Ernest S on May 23, 2021
BEST ANSWER: It takes 1 tank to bring pool up to 84 degrees and 1 tank to maintain over most of the summer and maybe 1/2 tank into September we have a 20/ 40 but we use the solar cover all the time unless it gets to hot in july other than that the cover is on unless we are in the pool
How can I tell what kind of heat exchanger is in it?
Rick B on Jun 8, 2018
BEST ANSWER: This heater has a copper heater exchange. On our website, if the title does not specify that it has a cupro nickel heat exchanger, it will be copper.
Can this be used for salt water pools too?
A shopper on Feb 6, 2018
BEST ANSWER: Yes it can be but it is recommended that you get the heater with a cupro nickel heat exchanger. Also, be sure that you have a check valve that will go after the heater.

does this heater match up to LLG175?
A shopper on May 7, 2021
Is there a list of options for trouble shooting unit (Raypak P-M336A-EPC) if there is no ignition? It has been dormant for approximately 5-6 years, pool was recently renovated. I fired it up twice last week, worked fine, but now, it will not light? The 500 gallon propane tank reads 30% full, pressure 15%. Any insight would be great. Thank you.
