Rinnai Pro Dealer

Rini Pro Dealer

Your local Rinnai Pro in New Hampshire

At GSMS, we have been installing and servicing Rinnai systems for New Hampshire homeowners since the early 2000s, before many companies in the area had even heard of the brand. Rinnai brought tankless water heating to North America in 1999 and is the first major tankless brand to manufacture here in the United States, so when you choose GSMS, you are pairing a trusted, innovative brand with a team that knows it inside and out. As a Rinnai Pro, we offer the full lineup of Rinnai products, backing up heating and plumbing systems built to last.

Why choose GSMS for Rinnai?

  • Decades of Rinnai experience: We have been installing Rinnai since the early 2000s and have been a Rinnai Pro since the program began. That kind of history means our Specialists have seen it all and know how to match the right Rinnai system to your home.
  • Factory-trained Specialists: Every year, Rinnai comes to us for full, in-depth training. They bring actual units into our conference room so our team can stay sharp on installation and service. Rinnai systems are even engineered so that every component can be removed with a single Phillips screwdriver, which means faster, cleaner service for you.
  • Extended warranty protection: Because we are a Rinnai Pro, we register your qualifying Rinnai tankless water heater in the Rinnai PRO Portal, which extends your service plan coverage well beyond a standard installation. It is one more way we protect your investment for the long haul.
  • The full Rinnai product line: As a Rinnai Pro, we install and service all of the Rinnai products we carry with no limitations, from their tankless water heaters to their heaters and boilers.
  • Natural gas and propane: We install and service Rinnai systems on both natural gas and propane, so we can fit the right solution to your home's setup.
