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...

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...

However, since the water is heated on demand, it can take much more time for the hot water to get to the faucet than a conventional hot water unit. While the time will vary depending on the distance the water travels, this results in wasting a lot of water waiting for the water to get hot - which adds to utility costs. Also, if you are looking to save on your gas bill with this unit...you won't. I have used this unit for 8 months (same household conditions before and after) and have seen no significant decline in my gas usage. When you consider the cost of installing this unit against a good quality conventional tank water heater, your payback on a tankless unit is quite long...C.R. says 22 years is the average, but I think that is generous. Also consider that tankless units cost far more to install, as special intake and exhaust venting is required. Rinnai uses an innovative 2 in 1 vent system... Read more |
