Their Customer Service is horrible. Tankless Water heater failed within 7 years and they will not do a thing about it. Throw your money out the window. It's more entertaining

I was advised by Rinnai the wireless component (remote and controller) have no warranty, The remote control when "exposed to moisture" will not work. The system needs to be initiated "warm up the water," up to 10 minutes prior to use This is to ensure the hot water lines are hot; this is problematic. In the kitchen, for example, you may use up to 5 to 7 gallons of water before getting hot water. I live in a 3,200 square foot home and have 4 remotes. One remote would not be sufficient. Not happy with the system, it's not ready for prime time and Rinnai customer service is not helpful.

Petro Home Services installed my direct propane hot water heater. It lasted 3 years. Rinnai would not replace the unit, but only the parts. It took Petro the whole day to try and fix the unit before I told them to replace the whole unit; they didn't have a clue. Rinnai doesn't stand by their unit.either After spending $2,500.00 in a new unit and labor, I have a new unit at my expense. Both companies are terrible. If the unit goes again I will replace it with an electric hot water tank. So much for tryig to install something that I thought would be efficient. I tried to ask the plumbing board in my state for advice and he just laughed. Thanks, Chuck Chepachet.

This product is the most terrible hot water heater. When our traditional hot water heater broke down after 15 years, we bought this lemon. It will give cold showers intermittently and take up to 10 minutes to warm water in the kitchen. Please do not buy!

We have been having problems with our Rinnai instant hot water heater since it was installed. We were talked into it by the company that we hired to install our hot water heater. It quit working a month after it was installed and they replaced it. The new unit quit working two months after it was installed. The product is junk! Rinnai won't replace it or give us our money back. The company that talked us into it is going to eat the cost and not sell the Rinnai brand anymore.
