Free Hot Water Receives New OG-300 Certifications with Several Made-in-USA Solar Hot Water Collector Manufacturers

Free Hot Water, a San Jose, California solar thermal distributor and engineering firm, announces new residential solar thermal kits with U.S. solar collectors. The new OG-300 kits include either Sun Earth, Inc, Solene, Alternate Energy Technologies (AET), or Solar Skies OG-100 collectors, depending on the customer’s region.

Shipping costs for solar collectors can significantly raise the final cost of OG-300 kits, decreasing a solar project’s bottom line. By partnering with these four U.S. solar collector manufacturers, Free Hot Water can reduce the shipping costs for its solar installer customers.

Collectively, our new collector manufacturer partners have warehouses that cover the four corners of the U.S., making it very easy to have the panels shipped directly—and sometimes locally—from the manufacturer to the client. At the same time an OG-300 order is placed, the smaller and less bulky “Balance of the System” items are immediately shipped from Free Hot Water’s San Jose, California warehouse. Additionally, complete OG-300 systems are now available for pick up at several locations throughout the country. Between the existing Green OneTec collectors and the four U.S. manufacturers, the Free Hot Water motto “Relax – We’ve Got You Covered” has never been more apparent.

All of Free Hot Water’s new OG-300 systems are certified by Solar Rating and Certification Corporation (SRCC) and qualify for solar thermal rebates in California and many other states.

Kits can be ordered with options for installing on a flat roof or a pitched roof, and all include:

  • Either two or three certified OG-100 solar thermal collectors.
  • An IAPMO-certified storage tank with a solar heat exchanger.
  • A pump station with differential controller.
  • Easy-to-assemble racking for either flat or pitched roofs.
  • Freeze protection via a closed loop glycol system.
  • Braces, bolts, and hardware for installation.
  • Complete set of instructions for installation.
  • Free Hot Water customer care via email or phone.

Free Hot Water OG-300 systems also include a 10-year warranty on the collectors, as well as limited warranties on other components.

For larger commercial applications, Free Hot Water also offers pre-engineered solar kits with up to 64 OG-100 collectors—ideal for apartment buildings, hotels, restaurants, Laundromats, and nursing homes.
