Well worth the money. Excellent unit.
Style: Natural Gas - Indoor - 6.6 GPM
Installed this several months ago. Install is simple if you know what your doing. Works amazing! Now the water heater closet is more storage space. The temperature control is great, you can look up how to override for hotter temps. Saved a lot of space, works excellent. Great unit for the money.

Works great

Year or so in and my dad still says it’s the best showers he’s ever taken. Can run while mom does laundry, and unlike electric it replaced, no “cold water sandwiches”

Rinnai all the way!
Style: Natural Gas - Outdoor - 9.8 GPM
With the proper installation, this unit works like a powerhouse, the appearance is sleek and pleasing, competitively priced, the controller is at the front of the unit. It's heat transfer and capacity is super efficient and you have the option for external pump and timer control. It's simply the best.

Gas Line size is 3/4" needs to be in specs. No customer service.
Style: Propane - Indoor - 5.3 GPM
The unit seems to be well made, BUT, please note, this product needs a 3/4" propane gas line. We couldn't find what size line it took in any of the specs or description. Only until we received it and got it out of the box did we see in the instructions that it took 3/4" line (and that info was hard to find). Now it is non-returnable. Expensive mistake! On such an important component of the the unit, it should be in the description and the specs so you know before you order it. Hindsight, we should of contacted the seller and verified. They will not respond to our messages after we have bought it. Customer service is nonexistent from this seller.

Tankless water heater
Style: Natural Gas - Indoor - 9.8 GPM
Purchased this Rinnai model to replace an older Rinnai unit that was nearing its useful life. Installed by a licensed plumber with no difficulties. In fact, the supply lines for hot/cold water and natural gas were in the exact configuration as the replaced unit. It has worked as expected in the week since installation, excellent water flow, consistent temperature, and quiet operation. Hoping for 20 years of service!
