Overview of the Ultra

The Rinnai Ultra is a wall-mounted, condensing tankless water heater with an energy factor of up to .96. The Ultra is Energy Star qualified and available in five sizes: 130,000, 152,000, 160,000, 180,000 and 199,000 BTU. Its two heat exchanger design increases efficiency and durability while reducing maintenance, and an integrated recirculation pump helps keep a steady supply of hot water in the supply line, which reduces water usage while creating a faster supply of heated water. The unit provides flexible venting by allowing for either concentric polypropylene or dual-pipe PVC/CPVC venting.

"Greatest change I have ever made"
I just recently changed my water heater. About 4 months ago I got fed up with running out of hot water when we were all getting ready in the morning, so I started to look into alternatives and found out about the tankless water heater. I immediately got my bills to get my usage rate and find something that could supply enough hot water for my family. The last water heater was getting rusted, and instead of fixing it we went with this better option. The operating costs are cheaper, and it does a better job. Also, it is not much more expensive than the tank model. I do recommend this to everyone, I can't believe it is not our default water heater system. I can't say I dislike anything about it, and all of its features are way better. It is less bulky, and better looking than the older one, and it does a better job.

"Not dependable"
If like most of us you grew up with a tank of hot water that was continuously hot, then the heat as you go "sounded" good. Not so. I have this unit, commercial grade since I have four bathrooms, in a new house. I rent this as a premium vacation rental. I have constant and continual problems with renters - in a premium property remind you- that have no hot water. Always a new problem. The engineering on this is terrible. Pay attention to these reviews. Get a tank.

"Nobody will work on them"
Dealers love to install them, but nobody will repair them. The Rinnai reps will keep you on hold hoping you get frustrated and hang up. They will give you absolutely no helpful information. They will string you along till you get tired and frustrated and just hang up and go to a tanked system.

2 weeks now with no hot water! Parts are being thrown at the unit. Only a four year old unit, parts are warrantied but at the cost of two kids, a newborn and a very unhappy wife that have to take showers and baths at a hotel, as family lives far away. If the owner of the company went without hot water for his family for that long, I'm sure there would be a new unit on the wall. Run away from this company. It's not worth the money, and the twenty year service life is a joke. I need to heat water on the stove now to do my dishes. Thanks.
