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 Ruud on duty.Basic Data

PolyTuf Textured Powder Coating
The Ruud 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
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.
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. Ruud also uses thick stainless steel tube sheets for robust construction and rust free operation.
The 156 is available standard with Ruud’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 Ruud 156 heater is a set of 2" flange connections to make your installation secure and effortless.
The Ruud 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.
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.
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.
