Above Ground Pool/Spa Heater - 156A
The Raypak 156A is the perfect choice for larger above-ground pools, spas and inground pools. The 156 has up to 50% more BTU's than the competitors' above-ground pool heaters. More BTU's means quicker heat-up. Extend your swim season, open your pool earlier and close it later. Your pool is always ready when you have a Raypak on duty. 
Basic Data
Model NumberFull BTU InputIndoor Stack dia.
PolyTuf Textured Powder Coating
The Raypak gas heater has a polyester-coated, non-corrosive cabinet that is more durable than solvent-borne and waterborne-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.
Wind-Resistant Design
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.
Polymer Headers
Prevent rust stains from harming your pool or spa’s surface, giving you years of trouble-free swimming pleasure.
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. Raypak also uses thick stainless steel tube sheets for robust construction and rust free operation.
The 156 is available standard with Raypak’s propriety AFT digital control. This control handles all the safety functions of the heater as well as the electronic ignition and flame supervision. State of the art diagnostic reporting and fault recording. This is the same control we use in our bigger gas pool heaters. Only the best will do for the model 156. The electronic ignition system requires external power (120VAC or 240VAC) and generates a pilot only when there is a call for heat. Units come with a 3 foot, 3 prong power cord.
2” Water Connections
Supplied with every Raypak 156 heater is a set of 2" flange connections to make your installation secure and effortless.
Automatic Bypass
The Raypak 156 comes standard with a built in water bypass so it can handle different GPM’s without having to adjust your flow rates manually. The bypass also helps keep a constant engineered flow through the tubes to help reduce condensation caused by cold water.
Burner Tray
Every burner tray is built to last, from the stainless steel burner deck to the aluminized metals used in the heat sensitive areas. Innovative design allows for the easy removal of the tray 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.
Energy-smart Raypak heaters consistently achieve the highest efficiency ratings. They meet or exceed all federal and state standards.
Available for natural gas or propane.
Please note the Raypak model 156 is not designed to meet the emissions regulations in areas requiring Low NOx levels.
Reduce input 4% for each 1000 feet above sea level when installed above 2000 feet elevation.

will this heater handle 15,000 gallons?
Mike B on May 20, 2016
BEST ANSWER: I've been using this heater for two seasons now and I'm very happy with it. My pool is 18,000 gallons. Water temp raises about 1.5 degrees per hour, depending on outside temp.
Gas pipe size ?
A shopper on Mar 5, 2017
rollout sw open ?
paul k on Sep 6, 2015
BEST ANSWER: raise the flue vent high enough to get draft
how do start up the heater???
phil m on May 12, 2017
BEST ANSWER: Turn the switch on, set it to pool or spa mode and use arrows to set temperature. It should fire up if demand is needed (pool needs warming up).
Is this (156K) appropriate for a 9 x 16 Endless Pool? Or is (106K) a better choice?
David C on Aug 26, 2016
BEST ANSWER: I will say depending on the outside temp makes the biggest difference. With my 15x30 above ground pool it rasied it about 4 degrees in about 1.5 hours with temps in the middle 70's. I oversized mine actually because it works my pool and my hot tub, I beit not at the same time. It has saved me a lot of money keeeping my hot tub at temp at anytime, rather than the electric heater which just sucked the juice
Is this heater suitable for salt water?
A shopper on May 21, 2018
BEST ANSWER: Yes but like any salt water pool if you let the scaling of the water build up it will endanger the heater.
can you reduce the water connections to 1.5" ?
A shopper on May 29, 2017
BEST ANSWER: My entire pool piping assembly is 1-1/2" and I connected my heater using 6' 1-1/2" flexible hoses and it works fine.
Which Raypak model would be equivalent to the Pentair Master Temp 250?
P J on May 1, 2018
BEST ANSWER: P-R266A-EN-C 009217 P-M266A-EN-C 009963 it has a 266K Btu rating and should be comparable to the Pentair. However the heat exchanger on the 156K model i installed did not hold up well and i had to replace it for the customer after 18 months
Late December thru mid February we have freezing temps here. Will this heater keep me from having to drain my above ground 15 foot pool?
G S on Jul 18, 2016
BEST ANSWER: Easily. Attach an Intermatic timer between the electrical power supply, and the pump plus the heater. Set the heater temp as desired and the pump to run whenever the circuit is energized Set the timer to 2 minutes on and 118 minutes off every 2 hours - 12 cycles per day- your pool will stay hot and ready to go whenever you would like. It will not freeze. It only uses 24 minutes of gas and electricity per day. You can shorten the time to-one minute on-if your pool is insulated enough.
How do you change temp or turn on and off?
Diane C on Jun 11, 2018
BEST ANSWER: Mine is digital. On front of heater is on/off switch.
On front is also display window. Open it and it shows
Temp and arrow buttons to turn up or down. Wish
I could send u a picture. Mine is a Ruud by raypack.
Does the heat exchanger fins come in any metal other than tin, I was told that there is a nickle type??
A shopper on Apr 29, 2017
BEST ANSWER: We have a model 155 and our paperwork indicates it is a Copper fin tube heat exchanger. We havebeen more then satisfied with this heater. Hope this helps with your question

flawless, simple and very easy to set up and use. Following installation recommendations with a timer controlling both the Raypak Above Ground Natural Gas Pool Heater and the pump, we set the timer for 2 minutes every 2 hours. The outside pool is ready to use anytime while using a tiny minimum of gas and electricity through the winter.

Great Heater
We are very happy with this heater. We have been looking around for a while for an above-ground heater, and definitely found this one to be the best price. Its actually a very nice-looking heater and is very efficient. Heats the pool quickly. I would recommend it!
