What people have to say

“The flow of hot water is great. I can adjust the temp as needed. Very happy so far..the unit is mounted outside of my home.”

“Installed a month ago and love it. We have not had any problems. We installed 2 to replace 2 tank heaters that were in old and new section of our home. Installed on the outside and freed up valuable space in our kitchen and in laundry room.”

“When we bought our home, the house had two 55 gallon traditional hot water heaters. One was in a third floor attic. I was obviously concerned that someday the water heater would leak and I would not only have to replace the water heater, but also replace the resultant damage. We replaced these units with two Rinni units ( which not only saved much space) but gave us peace of mind.”

“We recently had company stay with us from our of town for a week. One question they asked was why were we not running out of hot water. We explained and showed them the tankless, on demand Rinnai system to them. They stated they had just replaced their hot water heater this year and wish they had know about the Rinnai before purchasing their tank system. They said they know what they will replace it with now for when the next one goes out.”
