  • Flawless operation.
Style: Propane, Indoor Installation Size: 7 GPM
Replaced my Camplux with Rinnai in my Airbnb. No more bad reviews because the heater failed to ignite. Works like a charm.

  • I installed similar unit over 20 years ago ( after taking Rinnai class ). Excellent product.

  • Much cheaper than the local gas company's price.
Style: Propane, Indoor Installation Size: 11 GPM
I didn't rate technical support or ease of installation, because the gas company was paid to install it. Also, the temperature is defaulted at a max of 120 degrees Fahrenheit, but you can adjust it to 140 degrees Fahrenheit after following a YouTube video.

  • Not worth it
Style: Natural Gas, Outdoor Installation Size: 5.3 GPM
Update. Plumber has been here again and can't clear an error code 12 from a brand new system. This is ridiculous! We'll be reg this overpriced hunk of junk Had it installed and it didn't get the water hot. Paid an extra $450 for another plumber to come fix it. Still doesn't get the water hot. Don't waste your money ... show more
