As of 2015, many Raypak boiler parts can be purchased through e-commerce websites such as Parts4heating.com. Some parts may not be available online depending on the boiler's make and model.
For quality assurance purposes, the Raypak master catalog should be consulted. An illustrated parts list can also be found on the Raypak website.
If a necessary replacement part cannot be found online, all parts for current Raypak products can be purchased through independent contractors who represent and install Raypak water heaters, pool and spa products, and boilers. Many old models of boilers have been made obsolete, so the availability of certain parts depends upon which Raypak boiler the user is attempting to fix.
