Rinnai RE199iN Non-Condensing Natural Gas Tankless Water Heater, Up to 9.8 GPM, Indoor Installation, 199,000 BTU

this tank less water heater was installed by Weeks electrical Company and did a good job

We live in a climate that does not get real cold so I can't say how well it would operate in such a location. That said, we love this! Gives you hot water when you need it just like expected. We have wanted to go tankless for years but it was unaffordable in the past. This unit was the price of a high end conventional unit and so far has worked much better than the POS Rheem fancy expensive water heater ever did. We had to modify some stuff in our attic/roof for the right size venting to fit. Worth the time trouble & expense. Looking forward to having on demand hot water for years to come!

This is a larger unit replacing an older unit which has performed very well for 12 years and maybe nearing end of life. I am a believer in early replacement to avoid potential panic if any appliance breaks down.

We replaced a 12 year old, slightly smaller Rinnai model with this unit. It's running well, and more efficient than its predecessor. Completely satisfied.
