Review: Tankless Water Heater Saved us Hundreds$$$ in first year, more hot water than you can use! - We had this Rheem Tankless Water Heater (Natural Gas) installed a year ago and it is fabulous. Not to waste precious water, but this thing is amazing, set at 120 degrees Fahrenheit, it never never never runs out of hot water for a nice loooooong shower. It is reliable, very compact and we are saving hundreds of dollars a year on gas costs by getting rid of our old 80-gallon tall cylindrical hot water tank. It leaked. This new tank is solid. We bought the style that is installed outside the back garage wall so we saved even more space in the garage/utility room and we saved a couple of hundred bucks on not having to buy the extra interior venting system and install a new vent hole through the roof. The outdoor style is the best!
Review: Excellent product, excellent service replacing a bad pressure release valve - The valves were super easy to install. I'm actually looking forward to performing the maintenance on this heater next year! I had a problem with the 150lb pressure release valve included in the kit. It was spontaneously opening up about 3-4 times per day, only for a few seconds at a time. The amount of water it was releasing was very small, but it made quite the whistling hum each time. I could hear it from anywhere in our house. I thought giving it a few weeks to "settle" in after the install might resolve it, but no such luck. A quick call to Webstone this morning and a replacement pressure relief valve is on its way. This saved me the hassle of uninstalling the whole kit for a return to desertcart. Great customer service and a well built product.

### ⭐⭐⭐⭐⭐ Tankless Water Heater Saved us Hundreds$$$ in first year, more hot water than you can use!

### ⭐⭐⭐⭐⭐ Excellent product, excellent service replacing a bad pressure release valve
*by T***H on April 25, 2014*

### ⭐⭐⭐⭐⭐ service valves are a must have for tankless water heaters. they make acid flushing easy. See my flush kit details enclosed
*by T***Z on October 17, 2014*

If you bought a tankless water heater you must buy these. It is essential to flush your water heater a few times per year. Most bad reviews on tankless water heaters are due to lime build up, and lack of proper maintenance. This kit makes acid flushing your water heater a very simple task. You also need: Superior Pump 91250 1/4 HP Thermoplastic Submersible Utility Pump Whirlpool 8212546RP 4-Foot Black Rubber Washer Hoses, 2-Pack found here on Amazon, as well as a 5 gallon bucket from your hardware store, and a minimum of 2 gallons of vinegar. The pump above will cavitate if you try to get by with one gallon of vinegar. If you find this review helpful, please click the helpful button below.
