The perfect choice for aboveground pools and spas, Raypak is the only manufacturer of this size heater to use all the engineering and components utilized in their bigger gas heaters. The unit is fully serviceable and built for years of operation. This may be Raypak's smallest pool and spa heater, but its built to the same exacting standards as the rest of their products. Extend your swim season, open your pool earlier and close it later. Your pool is always ready when you have a Raypak on duty.
Please note the Raypak model 156 is not designed to meet the emissions regulations in areas requiring Low NOx levels.
