  • Wow!

    All I can say is, "Wow!"... This water heater is great. I purchased my house in 2008 and the old water heater has been in this home since 1990. About 4 weeks ago, I needed to replace a faucet in the laundry room. I turned off the old water heater and shut off the water supply to the house. When I replaced the faucet and turned the water back on, the 21 year old beast sprung a leak.... dripping water at a moderate rate into the drain pan beneath it (thankfully, there was a pan installed!). After doing a decent amount of research online, I found out that my gas company has a rebate program for customers who upgrade their water heater to a more efficient model. The more efficient the heater, the bigger the rebate (up to $450). I began hunting around my local big-box home improvement stores (**** and ****) to see what they had to offer. To my dismay, their cheapest models were not efficient enough to qualify for a rebate (I needed an "energy factor" of at least .63). And the models with the higher efficiencies cost over $1000!! Needless to say, I hightailed it back home to see what the various internet retailers had to offer. The prices online were certainly easier to stomach, but the shipping from a lot of them was exhorbitant (especially the tank-style monstrosities). I found a few sellers on **** selling some strange chinese-brand of tankless heater for around $400, but I was concerned about using **** for such an important purchase. What if the water heater was defective? Or sprung a leak? No... I wanted a reputable vendor selling a decent brand. That's when I saw the Eccotemp on Overstock. At first, I thought it was too good to be true. A price under ***, with $3 shipping?? After reading a bunch of review, I decided to pull the trigger. Overstock only had a few left, and I really wanted to take a hot shower! After paying for the water heater, I expected to wait AT LEAST a week for it to arrive... but lo and behold, it came in THREE DAYS! Talk about fast service! I was absolutely thrilled! I've never installed a water heater, and after a lot of planning, trips to **** for parts, screaming and bruised knuckles, I managed to get the old water heater out and the Eccotemp plumbed up to the old piping. It works great! On demand, endless hot water. No wasted energy heating 40 gallons of water just sitting in a tank! It has an energy factor of .80! I can easily change the temperature of the water using the digital controls. It's so small, I have more room in my utility closet for my lawn and garden tools! And to top it all off, my gas company sent me a check fours days later for the FULL AMOUNT of my purchase... so basically, it was "FREE"! (I still had to pay for all the parts, including the gas line, pressure relief valve, copper pipes, flexible water lines, exhaust pipe, etc). Mind you, installation is not for the meek. But, with the right prep, any homeowner comfortable with hand tools and some basic plumbing can install one. I didn't even use solder, instead opting to use a special "copper epoxy" specially made for plumbing copper.

  • NOT RATED

    Seems to work just fine. However, they are not rated by any professional plumbing association and/or not rated ENERGY STAR. Therefore, after buying 4 of them for an apartment building i own in Los Angeles they would not pass inspection and i was forced to remove them. When they get some certifications i think this will be a good product.

  • Updating a tank-type heater.

    I think this may be helpful for those who are considering replacing an existing tank-type heater, The heater arrived exactly when it was supposed to; the thing that got me was how small it was, even though I'd checked the dimensions before purchase. We have very old and internally rusted 1/2" galvanized pipes, but are planning to finish a copper replacement project soon. Since I didn't want to do things twice, I used copper for the neccesary repiping; as I didn't want to clog the heater, I elected to install a water filter on the inlet side which lowered the water pressure even more, near to the bottom end of acceptable. A pressure safety valve of 150 PSI or less must be installed on the outlet side and is not included; I pulled the one from the old heater, which worked fine after I built a T extension to accomodate it. The heater should be mounted to a stud and as close as posible to the old vent system; you may be able to grandfather the old system if it's in good shape, the heater is located in an unheated area with good ventillation. and the vent pipe has several inches of clearance (particularly on the top) Another important thing is the temperature setting; I found with the gas in 1/2" pipes that the max temperature was just under 115` F. The important thing to remember is the hot water flow is endless, so it is not neccesary to mix with colder water to extend the usable time; consequently I set mine to 114`. This worked perfectly and I could shower as long as I liked, while allowing a slight mix with cold water for a comfortable starting temperature. You'll probably need an extension cord for the electronics; although the length is given as 10', it is actually 6'. I think this heater is a HUGE bargain. It cost less than replacing the old one with the same model, has a longer warranty and should save a lot of money over it's lifespan, Although I had initial concerns over whether it would work for my situation, I found it did with a little tweeking and was very pleased with almost everything about it.

  • Good at first... Now is going to the trash.

    Initially, I loved this unit. I told everyone and referred several people. Now, three years later, I have a unit that is unusable and am going to buy a more reputable and solid rheem product. The flow sensor failed and after getting the replacement one and paying $54 for overnight shipping, the flange it goes into fractured and failed, spewing water and flooding my basement. All the while, I'm told by "service" that it was my fault and it is not their problem. Nice! Don't waste your time or money unless you plan to replace it in 3 years and/or like for your house to be flooded.

  • Check your gas service and venting location first

    This thing MIGHT run like a champ but I never found out. Why? because there was not a suitable location to vent the water heater in my inside-of-group rowhome. It can't be vented into an existing chimney like the old tank heater that only drew 30,000 BTU's of gas. The vent has to be 4' from a door or window and the basement windows and first floor rear door didn't have the clearance. Also, check your gas service if you are using NG to be sure your service and meter will support the 140,000 BTU gas load. Mine would not. The gas company would do the upgrade free of charge but it would entail digging up the front yard and replacing the gas meter. Installing this thing unless you live in the boonies is a job for a licensed plumber/gas fitter.

  • Gas Indoor Tankless Water Heater

    Replaced my mother's old water heater with this unit. After removing the old water heater you will need to buy some new fittings, relief valve, shutoff valves, and relocate the water pipes toward the wall where you will hang the unit. You will also need some vent pipe and some connectors and angles for the vent. Expect to spend about $160 more on these parts to complete the installation but it is well worth it in unlimited hot water, as long as you don't have too much demand on the system at once. Also much more economical to heat the water only on demand and not all the time. Installed for almost a whole year now with zero problems.

  • very pleased

    I am very pleased with my experience with OVERSTOCK.COM, and most certainly will make future purchases from them. My tankless water heater arrived in 5 days. (I had allowed 7 to 10) It was in perfect shape! The price was just a few dollars more then I would have paid for a tank water heater. Now every time I think about making a purchase, I always check out OVERSTOCK.COM first. W. C. Snow

Can this unit be used in a no-vent home? needndc on Nov 26, 2012
Subscribe to Answers
Answer This Question

Unfortunately, this item requires vents. According to ANSI code, gas tankless water heaters normally require stainless steel, category II/III vent pipe. This is due to the fact that gas tankless water heaters actually burn at a higher BTU rating. As such, the gas is extremely hot when it leaves the water heater, but cools quickly. This cooling process results in condensation which could eat through regular galvanized pipe. For our tankless water heaters, we utilize Z-Flex single walled 3” diameter stainless steel venting. overstockcustomercare1 on Nov 27, 2012

Is there an elevation limit to this water heater? I know that it may sound like a silly question - but many tankless water heaters I have seen are rated up to 4500 ft (I live at 4700) and I wanted to know if there was an altitude rating. Thanks joesurf on Oct 9, 2012
