  1. 5 Stars - 5.0 out of 5 stars Excellent tankless water heater, May 12, 2010

    I did a lot of research before buying this and having my licensed plumber install it to replace a very old 40 gallon gas water heater. I am very pleased with it, and its price here was better than anything we could find locally. So particularly with the tax credit available this year, I know that I will have paid for this (including installation) within 7 years based on our usage and current gas prices in our area. My plumber liked it too.

    If you're thinking about a tankless water heater, however, you must realize that by definition it will take slightly longer to get hot water at your faucets. Right now hot water starts flowing from your big tank as soon as you open that faucet. With a tankless, the computer kicks in when you open the faucet, the gas flows to the burners, the electronic ignition creates flame, and the water is heated as it passes through the heater.

    This heater seems to come on instantaneously when a faucet is opened (with a satisfying whoosh) and hot water reaches our faucets almost as fast as it used to. It may be fractionally slower to get there, but it's endless hot water, at a precise temperature, and those are the two things we didn't have before.

    My other suggestion is to make sure you size your tankless properly for your use - this one is perfect for our 2.5 bathroom home. There is a larger one available if you need the extra capacity.

  2. 5 Stars - 5.0 out of 5 stars Hot, Hot, Hot!, February 14, 2010

    While doing a major remodeling which involved relocating our water heater, we decided to go tankless. Since we were upgrading our shower and installing a garden whirlpool tub, we knew hot water demand would soar. Also, we knew both showers would be running at the same time and the old water heater just would not be able to keep up. Our plumber/HVAC contractor is a specialist in energy efficiency, having previously been an executive with a large national energy efficiency company prior to the bust. His recommendation: the Rinnai NG Tankless Water Heater.

    It takes longer to get one installed properly, with the extra venting and the materials required. Don't be part of the learning curve for your installer. Make SURE your installer has experience with tankless installations and ASK FOR REFERENCES. It is a different technology and the installation techniques are different from a traditional water heater.

    It is a space saving unit, and extremely quiet. And it can flat crank out the hot water! No lags, no lukewarm spaces, no waiting, just all the hot water you want when you want it! Our gas bill dropped about 15% in a much colder winter - no more water heater constantly running to keep hot water hot, no more shortened showers, and a very happy family.

  3. 5.0 out of 5 stars It Gets the Job Done, September 28, 2010

    I have owned this unit for one year. It has performred flawlessly. I installed it myself but, I had a plumber look over my plans. The most important part of the installation is the gas supply. I ran a three quarter line teed off right from the meter. This insured that the unit would get enough gas. I also ran a copper line from the heater to a six gallon electric tank. This eliminates the wait for hot water and the "sandwich" effect. My electric bill went up by about three dollars a month and my gas bill went down by twelve dollars. It might seem like it would take forever for this unit to pay for itself but, in my circumstance I have to use a direct vent or powervent water heater. These units cost about seven hundred dollars and carry only a five or six year warranty. We need to use a water softener so the tanks usually would only last about six years. This unit has a twelve year warranty so it will pay for itself after six years because it will last twice as long. We have four people living in the house and frequently have two showers running at the same time.

    The Rinnai provides more than enough hot water even during our cold Ohio winters. Plus, there's always enough hot water for the dishwasher or another shower immediatly following those two showers. The Rinnai water heater has exceeded my expectations.I highly recommend it.
