I have a pool heater that is a mini max purex model #400. Will the R336a be a compatible replacement.
Can the heat exchanger be repaired or it has to be replaced what is the warranty on this
My pool is salt water, can I run a heater with salt water? I only need it for a month in spring to heat up, because in texas the air goes to 90 by march, but the water takes a month as it lags
Hi Michael, when using a heater on a saltwater swimming pool you will want to use a cupro-nickel model so the exchanger does not fail prematurely due to the corrosiveness of the salt. Here is a guide that we put together called "Sizing Your Pool Heater" that may also assist.
We currently have a Lorrs 325,000 BTU Natural gas heater that is 18 years old and does not work. We are looking to replace it with the Raypak 336000 btu is this compatIble and an easy switch ?
Hi Christine, Yes these would be compatible heaters. You will have a little bit of re-plumbing as the plumbing ports are not in the exact same location.
I have a Raypak 2100 unit now, how do I determine what size it is? I want to replace the unit, if I purchase another Raypak will the plumbing line up?
Hi, Roy. You will have to locate the unit's service tag to determine the model and or the size of your unit. The plumbing will line up if your unit was manufactured between 11/01/04-Current.
Is this a commercial natural gas heater?
Is this the proper size (BTU) for a 50,000 gallon pool?
No, the Raypak RP2100 Heater 336,000 BTU NG ELE - PR336AEN is not a commercial unit.
We live in South Jersey and had a Raypak 336A that lasted 12 years before the bottom rusted out. We are looking at a Raypak RP2100, 336,000 BTU unit. Will the RP2100 be remote compatible just like our 336A was.
Also what is the manufatcure's warranty on the RP2100?
Dave, yes, the Raypak RP2100 Heater 336,000 BTU NG ELE - PR336AEN should still be compatible with the existing remote control system. There is a 1-year warranty from the date of purchase from the manufacturer. The warranty will cover you for parts but not labor.
When buying a replacement swimming pool heater, do you go by the BTU input or the BTU output?
Hi. The heaters are sized using the BTU Input/output rating. The output rating determines the performance of the heater and the heating time.
I have a 33 foot round above ground pool. I currently have a rp2100 model P-R265 A which needs to be replaced. What model Rapak heater would be the correct size for my pool?
Hi. The P-R266A model will be the correct drop-in replacement to the unit you have. If you want to go with a higher BTU unit which will heat your pool faster you can. This P-R336A or the P-R406A model will be sufficient, you will also have to increase your gas line too.
Can the electrical wiring be switched to the other side as well?
The current heater I have has all of the pipe connections on the left side of the unit and all of these have the connectors on the right. Am I able to get one with the connectors on the left so it lines up with the pipes coming from my motor and filter?
Hi, Sherry. All of these units come with the water connections on the right. They can be changed to the left, this will have to be done by an authorized technician.
how far does the pool heater have to be from the house - huntington ny
For U.S. installations, the point from where the flue products exit the heater must be a minimum of 4 ft below, 4 ft horizontally from, or 1 ft above any door, window or gravity inlet into any building. The top surface of the heater shall be at least 3 ft above any forced air inlet, or intake ducts located within 10 ft horizontally
Just bought (from you)received and installed PR336AEN in my 10 x 12 shed (replaced a laars) I have an indoor 8" stack from old unit, but see I need the Stack adapter and outer stack adapter for this unit. My question is, being its in a shed with ventilation Do I really need to use the chiminy at all ? Tell me why I would need this.
Hi, Ron. You would need the Raypak R366A/R367 Indoor Stack Kit - 009840 to get rid of the toxic fumes that the unit releases. You do not want to have the fumes trapped in an enclosed area, Although it may be ventilated it may not be adequate.
I am considering your 336 BTU heater. My pool heater sits to the right of my pump as you face. All your pictures show the hook ups on the right side of heater. Are they available with the hook ups on the left side of heater as you face?
Yes, the heat exchange can be flipped from the right side to the left side. Check out page 24 of the owner's manual for details. http://cdn.globalimageserver.com/fetchDocument.aspx?id=9858dad5-021a-4216-b0d5-1e29edd2f913
I have an old Raypak RP 2100 that I am looking to replace. Is this a drop in replacement?
What is delivery time to MA?
Hi, Pat. This unit is the same as the Raypak RP2100 series units. Delivery to MA can take 3-5 business days.
What type of electric does the raypak 336000 run of off? Also, if I read correctly 3/4" gass feed under 20' should be enough gass to run it correctly? I am eager to make this purchase so can you please let me know asap
Hi, Rob. This unit can be wired for 120 or 240 volts. A 3/4" gas line can be used for a run that is under 20 feet.
Do you carry the CR336EN version also and if so what is the cost and lead time for shipping,thanks David.
For the RayPak heaters we carry the standard, cupro-nickel, high altitude, low nox, and commerical models all of which are usually in stock and usually ship out a day or two after the order is placed.
I have a Raypak Model P-R336A-EN-X and I am looking for a simple remote to control the pool heater and adjust the pool water temp from inside the house. Can you recommend a simple remote that I can use just for the pool heater? Thanks
how loud is the raypak 330,00 btu heater,my pool pump,old heater is about 15ft from my pool spa, i'm,worried about noise ,thanks
What size heater for 30,000 gal inground concrete pool 20x40 and what is average aprox cost to heat with natural gas in northern NJ
will this heat a spa and pool. Does it need a remote module to control from the spa
My current pool heater is 265k BTU (Raypak P-R265A-EN), is 15 years old and didn't work all last season, so I'd rather replace than repair. I was thinking of going up one model because I don't have a cover and it can be hard to get the pool temp above 80 degrees when the nights are cool in May and September. Will I use a lot more gas heating my pool if I replace it with the 336K BTU model instead of the 266K BTU model? Thank you.
Hi John, Yes you would consume more gas with larger size unit. The 336 unit will also heat the pool faster than the 265. I would highly recommend using a Solar Cover or Liquid Cover to prevent water evaporation and heat lost which will save you money when it comes to heating your pool.
I just purchased a your Raypak 336000 BTU NG ELE heater. I live in New Jersey and my question is: should I place a cover over the heater during the winter months? If so, do you know where I can purchase one that will fit this heater. I thank you in advance for your assistance in this matter...... Len
MY RAYPAK HEATER CLICKS BUT IT WON'T IGNITE. THE WATER FILTER IS CLEAN AND RUNNING AT THE APPROPRIATE PRESSURE. WHAT COULD BE THE PROBLEM?
Hello Vic, It could be a few different problems. To properly troubleshoot the issue I would contact Raypac at 805-278-5300 or have a pool company come out to look at the heater.
What is the difference between the Raypak 336000 NG ELE and the Raypak 406000 NG ELE other then the price and BTU? Thanks... Len
Hi Len, The Raypak 406000 NG ELE unit will heater your pool or spa faster than the Raypak 336000 NG ELE unit because it has a higher BTU output.
Do you sell the Raypak 399,000 BTU NG ELE and if so, what is the cost for this model? Thank you in advance..... Len
My heater is about 85' from the gas supply and my existing line is 1", the pool holds about 38,000 gallons, which heater could I use and not have to dig up the old line, it's under the concrete pool deck!
What is involved with electrical hookup?
We can get you the instructions for the installation, but to keep the heater under warranty you would have to have it installed by a licensed electrician.
What is the difference between an Electronic and Millivolt ignition?
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?
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.

actually my success story is that I did my own reaseach then called a close friend who buys from INYO and highly recommended them. So, after talking at lenghth with the INYO rep, he answered all my questions and educated me about other fact concerning these products I was buying. He was thorough, informative, extremely polite and personable! The process was easy! The delivery was sooner than I expected and came off without a hitch! Will definatly use INYO pools for all my pool needs! Thank you guys, you are awesome!

I spent $100 here and there on replacement parts for my Jandy LXi400. It started firing up but cut out. I could not find the issue. I was not about to spend hundreds on a service call.
I read about heaters. I was impressed by Raypak reviews and standards. I am a little annoyed about there being no warranty for a self install - I mean why unless any fault is caused by the install!
Anyway. The delivery driver, although curbside delivery, helped me take it to the pool shed. Next day, I simply attached the half inch gas pipe (I had to buy a 2 foot piece since the gas valve is set farther back than Jandy) and wired TWO wires into the power of my Jandy aqualink power unit - its a dream.
It took about an hour. SOOO much better. Water heats great. Works with my Jandy remote. No issues at all. I love it. I have, and will continue to recommend both Raypak and Inyo.

Don't know. My son installed it
I called customer service and ordered a replacement. Customer service rep was courteous and the transaction was quick. You can't beat their prices with free shipping it was $700 cheaper than a quote from a local pool store! Shipping was quick too. Hook it right up with minimal effort and we're good to go. Thank you INYOPools!!!

Ordered the same sized raypack from inyo pools at a great price. The size and hookups were the same as the old one so no new plumbing was necessary. My biggest concern was that the company warranty would not be allowed unless installation was done by a licensed contractor. Since the heaters were basically identical, I decided to do it myself. Out with the old, in with the new. Took pictures of the old electrical hookups and installation was easy. New O- rings and the plumbing was done. Everything matched up perfectly. Opened the pool the next day and crossed my fingers when I turned on the heater. Two sparks and it kicked right in.
The price was 300.00 less than any other pool stores for the same unit and installation by a dealer would have been an additional 300.00 or more. I just opened my pool this year (2nd for the heater) and it kicked in after cleaning out the gas tube. It seems spiders build webs over the winter and sometimes prevent gas from flowing. Cleaned the line and heater kicked in. Very happy.
(5 out of 5 stars) Great value

Pros: quick ignition, quick heating, easy controls
Cons: only 82 fuel efficiency
After 20 years, the burner supports for by old millivolt Raypak finally rusted out. Our primary use for the heater is to heat the spa so we upgraded from a 220,000 to this 336,000 BTU and it really speeds up the time to get the water to 100 deg. The old millivolt required removing all the wiring and cleaning the connections about every 7 years. The new spark ignition is great. Inyopools shipped the heater the same day that I ordered it. Great service, easy installation. Hope this one lasts as long as the old one!
(5 out of 5 stars) Great pool heater for a great price from INYOPools

I had always been familiar with Hayward products. I had not been familiar with Raypak until I needed to replace my Hayward heater (300k BTU). Through my search for a heater with a similar hookup to the old Hayward heater (gas input on the left and electric on the right), I ran across Raypak. I am familiar with Rheem, so I thought I would give it a try, especially since the INYOPools price was very reasonable. The heater arrived on time and in perfect condition. Since I am fairly handy, so I decided to hook the electric and water up myself (I don't touch gas because I don't want to blow anything up). The electric was very easy to hookup. The line connects directly on the outside of the heater rather than being hooked up to a junction box inside the heater like my Hayward heater. The wire were clearly mark. So it was easy to wire the electric. The water hookup took a little longer. This unit is rather tall compared to other heaters. Check the dimensions to make sure you have enough headroom for the heater. The water input and output was at the same height as the output from my filter. So, I had to completely rerun the PVC. Thank goodness that PVC is easy to run. It took a few more 90's that I usually like to have. I had a professional hook up the gas last. Once it was hooked up, we turned it on. It fires up with no problem. In fact, I couldn't even tell it fired up until I felt the heat above the heater. This unit is very, very quiet. Also, it heated my pool in less than half the time of the 300k BTU Hayward heater I had. I have a 21,000 gal pool. The 300 BTU Hayward heater heated my pool about 1 degrees per hour. This unit heats my pool between 2 and 2.5 degrees per hour. It seems like a very efficient heater. I am very happy with this product. It looks well constructed and it does not seem like it will rust. I am a new Raypak convert and will consider their products whenever I need to replace this heater and recommend them to my friends. I would recommend their products to anyone who needs a new pool heater.

Very reliable heater. My original raypack heater lasted 17 yrs. With very few problems. I replaced it last year with the new identical 336000 raypack. Hook-up was a snap and have no problems to date. Looking forward to another 17 years.

Pros: Pricing and Shipping
Well built heater, received in the timeframe promised, well wrapped for shipping. Great pricing too; love that shipping is included. Only downside is that the heater was advertised as high efficiency, but when it was unwrapped, the yellow EPA tag described it as the lowest efficiency among it's competitors. I called to complain, and everyone points fingers at everyone else ("that's what the manufacturer told us....") Nobody stepped up and that's unfortunate.
