This unit is amazing! The HD price was hard to beat anywhere, and even the installer was impressed. I went with this unit as the low end of the Top of the Line RUCS condensing units. The Rinnai quality is amazing and with a certified installer I found the replacement of the boiler to be the single best home improvement I've done. Hot water does take 30 secs to 1 minute to show at the faucet depending on where in the house I need it, but once it starts flowing there is nothing quite like it! The Rinnai unit is attic mounted and I hear no mechanism noise and haven't seen any undesirable side effects. This 7.5 unit can run both showers and the kitchen sink and my HE washing machine a the same time. I literally cat imagine going back to a tank heater now, and its only been installed for a week. If you have natural gas already heating your water this is the ONLY way to go. And with the special pricing it will show a much earlier return on investment for me!

Great unit
I purchased the RUCS65IN 3/21 and installed it myself. The unit is very well designed and it takes up a very small amount of space. The warranty is outstanding. The No clearance spacing for unit mounting was a plus and I chose the condensing design for better flame use. By going with condensing allowed for venting without concern of spacing as well. My install is on a basement wall and direct vents through the joist spacing above the concrete foundation. The heater has provided gray service for the past 6 months since installing.

    Great product....Get professional advice and insta
    The tankless models come in many variations, I selected and bought my own without getting expert advice. The unit I purchased does great throughout the (Circa 1900) house except for two faucets that have always suffered from low flow...one being the kitchen sink...which now take even longer to get hot. No complaints about the Rinnai unit but I think I should have spent more for a unit that supports the re-circulation feature.

        Consistent Hot Water
        We have only had our Rinnai for about 7 months and we have had no issues with it. It consistently provides the hot water we need.
