Digital Controls

  • 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.

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 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.

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

  • Cupro-Nickel Fin Tube

This Raypak Digital heater has 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.

Im trying to replace a Rheem/Raypack model # P-M336A-EN-C. Is this the model? This is for a salt pool, natural gas.

Hi, Andy. This Raypak P-R336A-EN-X unit can be used as a saltwater friendly replacement for the P-M336A-EN-C model. This is a natural gas heater.

We are looking into replacing our existing STA-Rite 333 with another heater. We have a salt water pool. Is this Raypak product equal or better than STA-Rite and designed for salt water? Thank you.

A     Answered on 5/2/2017 by InyoPools Product Specialist Scott W.

Yes, the 336,000 BTU RayPak with the cupro-nickel heat exchanger is made for saltwater pools to hold up against corrosion.

Do you have a draft hood kit available for the R336A so i can install it indoors. If not, what about using the power vent kit and what is the cost for that?

A     Answered on 7/13/2016 by InyoPools Product Specialist Joe S.

The item you will need will be the Indoor Stack Kit, R336A, R367A - 009840 our part number  6238-122

Is there any harm in over sizing your heater to your pool size?

A     Answered on 6/1/2016 by InyoPools Product Specialist Alan M.

Hi, Bob. No there is no harm in oversizing the hearer on your pool. The larger the unit, the faster it will heat your pool, the less it will run. That translates into energy savings for you.

I will need to run about 250 feet of a natural gas line for this installation. Are there any recommendations and/or limitation to consider? Size of line, etc.

HI Bernie, Please refer to the Raypak RP2100 Installation and Instruction Manual for all installation requirement. You will also need to contact your gas company and a authorized Raypak installer for installation recommendations.

I have a spa only and a raypak spa/pool unit. Can I heat the spa when it is on the pool mode and will the spa heat any faster on the pool mode vs. the spa mode?

A     Answered on 2/23/2016 by InyoPools Product Specialist Lennox H.

Hi, Since you only have a spa it does not matter what mode it's in. The heater will not heat faster in a specific mode. The Pool/Spa mode is for applications that has a pool/spa and wants each body of water heated to a different temperature.

I'm looking for a pool heater and I see one at kijiji but is already 4 years old is it worth to buy it?

A     Answered on 5/1/2015 by InyoPools Product Specialist Lennox H.

Mario, I'm not sure what kind of Heater you saw at Kijiji and what price but with it being 4 years old it's not coming with any warranty, so that's a call only you can make.

What is the efficiency rating on this heater?

A     Answered on 4/10/2015 by InyoPools Product Specialist Brian M.

The Raypak 2100 unit I currently have, has a "pool" and a "spa" switch. Is this the same type of deal on Raypak model 010104, but digital? Can you heat both together, or only separately, or both?

A     Answered on 5/10/2013 by InyoPools Product Specialist Patrick P.

Yes, this heater will do the same job as your existing heater. Instead of two dials for spa and pool, the digital board will control both. You can set one temperature for the spa and one for the pool. You can also keep both bodies at the same temperature.

What is the difference between an Electronic and Millivolt ignition?

A     Answered on 10/10/2012 by InyoPools Product Specialist Patrick P.

The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.

Will a gas heater operate at the low speed of a dual speed motor?

A     Answered on 1/16/2012 by InyoPools Product Specialist Patrick P.

Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.
