What Is The Difference Between Rheem, Raypak and RUUD?

What Is The Difference Between Rheem, Raypak and RUUD?

Question: We often get asked what is the difference between Raypak, Rheem and RUDD heaters?

Short answer: Raypak is the oldest independent pool heater manufacturer in North America, and is a subsidiary of the Rheem Manufacturing Company. In certain markets, the Raypak pool heaters are labeled and sold as Rheem or Ruud, but are the same exact pool heater.

Long answer: Rheem, RUUD, and Raypak are all well-known brands in the heating, ventilation, and air conditioning (HVAC) industry, but they specialize in different areas and have different product lines. Here are some key differences:


  • Rheem is a manufacturer of a wide range of HVAC products, including air conditioners, furnaces, heat pumps, water heaters, and boilers.
  • They offer products for both residential and commercial use.
  • Rheem is known for its innovation in energy-efficient technologies and environmentally friendly products.
  • Rheem products are widely available through various distribution channels, including wholesale distributors, contractors, and online retailers.



  • RUUD is a subsidiary of Rheem Manufacturing Company, operating as a sister brand under the Rheem umbrella.
  • RUUD primarily focuses on residential and light commercial HVAC products, including air conditioners, furnaces, heat pumps, and water heaters.
  • RUUD products often feature durable construction and reliable performance, catering to the needs of homeowners and small businesses.
  • Like Rheem, RUUD products are distributed through similar channels, including wholesale distributors and contractors.



  • Raypak specializes in heating solutions, particularly in the realm of pool and spa heating systems, as well as commercial boilers and water heaters.
  • Their products are designed to efficiently heat water for swimming pools, spas, and commercial applications.
  • Raypak is known for its durable and high-performance heating systems, which are often favored by pool professionals and commercial building owners.
  • While Raypak is part of Rheem, it maintains a distinct focus on heating solutions for specific applications rather than offering a broad range of HVAC products like Rheem and RUUD.


In summary, while Rheem and RUUD offer a wider range of HVAC products for residential and commercial use, Raypak specializes in heating solutions tailored specifically for pools, spas, and commercial heating applications. However, all three brands operate under the Rheem Manufacturing Company, sharing some aspects of quality, innovation, and distribution channels.
