Raypak Above Ground Pool and 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.
Model Number Full BTU Input Indoor Stack Dia.
PR-R156A 105,000 6"
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.

Can this unit be installed and left outside?
A shopper on May 31, 2016
BEST ANSWER: Ours is installed and outside.
What currency?
A shopper on Mar 31, 2019
BEST ANSWER: Do not buy this heater for SPA!!! Heat exchanger can't tolerate SPA chemical and Raypak refuse to replace the exchanger even it is still under warantee.
I live in the Nevada High Desert...will the 156 propane heater work efficiently heating my 8000 gallon saltwater pool. The Penair one I purchased a year and a half ago has proven to be a HUGE disappointment?
Marie N on Jun 13, 2017
BEST ANSWER: Probably, do the math.

At sea level, It takes 1BTU to heat 1 pound of H2o 1 degree C . If your pool is 8000 gal your 156,000 btu/hr heater will take 20 BTU/hr to raise the temperature of 1 gallon 1 degree C. That means with a 156,000 btu heater, you can fill the pool and it will take about 3 days to heat the pool, add surface temperature losses and you have a heater size. Assume heaters are 80% efficient.

See the pool de-rate chart in the manual for losses due to elevation. Note, there are approx. 8 pounds/gallon water

The question you shud be asking is; What is your pool base line temp and how many hours are you willing to wait to heat the pool? Derate for elevation, assume reasonable surface and efficiency losses and that number will tell you how big a heater you need. I'll bet it's a whole lot more than 156,000 btu/hr.
Can I use raypak 156a with a salt water system?
Meomarg on Apr 7, 2018
BEST ANSWER: You can but remember to check Ph daily until pool stabilizes. High level of dissolved solids will eventually lodge in the heating tubes limiting the flow and shutting down the heater.
Is this hard to install on your own without a professional?
A shopper on Jul 1, 2017
BEST ANSWER: This heater is easy to install as long as the propane source is ready to be connected. Some experience with gas piping and pvc pipe is necessary.
