Rinnai has been delivering nothing but the best for almost 100 years and that award-winning dedication can't help but be noticed in its Ultra Series. The RU90eN and all of the Ultra Series Models offer Rinnai's incredibly efficient condensing design line of tankless heaters. Rinnai's Ultra Series Models utilize two premium heat exchangers to provide optimal reliability and durability. With a 0.96 Energy Factor and a sleek, innovative design, the RU98eN is the ultimate option, and is easily maintained thanks to included isolation valves.

Product Features

Compact design saves space.
What Rinnai has done to consolidate and concentrate its tankless units into barely the size of a suitcase is really remarkable. The RU90eN is designed to be able to be installed inconspicuously on any exterior wall or compact space, hiding your unit and freeing up valuable space in your home. Rinnai tankless water heaters are perfect for any home, including manufactured and modular homes.

Energy-efficient promise that saves you money.
Rinnai has almost a century of experience producing some of the most efficient, and highest quality, water heaters, and the RU90eN is no exception, using up to 40% less energy than traditional tank heaters. Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves precious natural resources by only heating water when you need it, as you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.

Continuous Water for Multiple Applications
You may not know it, but you're probably scheduling your life around your hot water supply. Stop waiting to turn on the dishwasher or flush the toilet, take control of your hot water supply. You should be able to have two people shower at once or do the laundry while the dishwasher is running. Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you're the last one in line for the shower.
