    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 SE+ Series. The RU98eN and all of the SE+ Series models offer Rinnai's incredibly efficient condensing design line of tankless heaters. Rinnai's SE+ Series models utilize two premium heat exchangers to provide optimal reliability and durability. With a 0.92 Uniform Energy Factor and a sleek, innovative design, the RU98eN is the ultimate option, and is easily maintained thanks to included isolation valves.
  • Compact design saves space.
  • The RU98eN 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.
  • Energy-efficient promise that saves you money.
  • Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves energy by only heating water when you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.
  • Continuous Water for Multiple Applications
  • 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.
  • Product Includes
  • (1) Cold Isolation Valve (Color coded: Blue)

Review Posted 08/08/2018 
replacing a old 100 gallon water heater that was an energy hog. Very happy with the speed of the hot water to the faucet and never running out of hot water. Can't wait to see the savings on our electric bill.

Very Happy with the upgrade
By Marcus A.

Review Posted 08/07/2018 
This thing exceeded my expectations, i have a 2 bathroom home and we would regularly run out of hot water with a 40gal tank heater. When my tank was showing signs of leaking i started researching tankless and found this heater great price and better performance. I was skeptical that i was going to have to use a higher water temp setting being on a well in michigan, but we are only on the second settings at 125deg F, and the water is plenty hot and produces tons of hot water. This heater is amazing. Just do your home work on what you need if you are doing the install yourself.

Very good water heater
By Tim S

Purchased 07/08/2018 | 
Review Posted 07/30/2018 
I read a lot of complaints about how long it took to get hot water. The only thing I can think of is that people have really long lines because I notice almost no difference between this and my standard hot water tank. about 30 seconds and my water is hot.

Two weeks and all is well. Too early to really pass judgment on how well it works in all conditions such as freezing weather and mud daubers. Beautifully made and very quiet.
