Answer: 
I would advise against using a gas feed less than the requirements of 3/4. This thing needs a strong flow of gas and air to burn hot enough to heat flowing cold water. Any modifications I am sure would impact the units capability and possibly damage it. I would run a 3/4 in gas line if your meter will support it.

Answer: 
Tony, do the gas flow calculation on page 52 of the instructions (available on-line), go to the table on page 54 to get the BTU/Hr vs. pipe size.
I suspect you'll need at least 3/4" for a short pipe run, 1" for an average run (40').

Answer: 
No. It is recommended that you use only the 3/4" minimum. You can check with your gas supplier for their recommendation on the length of pipe sizing in order to accommodate the 199,900 btu natural gas requirement. This may require you to upgrade your current pipe size.

Answer: 
You must have 3/4 inch gas pipe for the entire run feeding to this Rheem tankless water heater. This unit generates 199,000 BTU so 1/2-inch gas pipe is NOT adequate.
In some cases you may need a 1-inch pipe from the gas meter to the point that the gas line starts to split up to feed other gas appliances in your home. This will depend on the number and type of gas devices you have in your home.

Answer: 
The condensate on my unit is a slow drip unless we're filling the bathtub. Then a small but steady stream comes out. It goes into a drain basin that gets pumped up to the septic tank. The volume of water is small but will eventually overflow a bucket.

Answer: 
I didn't install the unit to save money. I am sure there is a cost savings do to the fact I am not heating a 60 gallon tank of water 24/7. Now I am heating only the water I use when I turn on the hot water faucet.
The main reason I installed it is I will not run out of hot water! Run the dishwasher, the clothes washer, showers, bath and etc. everyone has hot water!

Answer: 
Cost savings will vary depending on whether you're replacing an existing electric or gas water heater, how high you set the heater thermostat, your hot water usage, and the electric or gas rates at your location.
Your situation is doubtless quite different than mine.

Rated 4.4 out of 5 by 92 reviewers.
Rated 5.0 out of 5.0 by Great tankless heater This was a DIY project when my tank water heater started to leak. This ended up being a much bigger job than I thought but my house is over 100 years old so that may have something to do with it too. I ended up running new PEX water pipes, upgrading and extending the gas line to 3/4 black pipe and new electrical to the unit. For me the hardest part was installing the venting. I had to drill through the brick to install the venting and since I live in a row home there was no room to feed in through the outside and on the inside there was a lot of wires and pipes in the way. The only other issue I had during the install was trying to figure out what the condensate trap in the pvc vent was. I thought it was something you can buy but apparently its just a section of 4" pvc with 3" adapters and drain you drill into the bottom. Home Depot had no idea what I was talking about but I later found it in the directions (who reads those?) That said, I've only been using it for a few days now but I get plenty of hot water. Oh and one more issue (which may not be a problem) is I noticed the display flashing P1 which means too little water flow for unit to operate but the water was turned off at the time. I reset it and so far so good. October 4, 2016
Rated 5.0 out of 5.0 by Fantastic heater I purchased the Rheem ECOH200DVLN from Home Depot to replace a Bradford White 48 Gallon Powervent tank unit that started leaking. I have a 4 Bedroom/3 bath house and so far this unit delivers consistent hot water as needed. A can have the washer and two showers running simultaneously without issue. The units fan(which turns on when there is a call for hot water) is much quieter than the power vent on my previous hot water heater. Please note that if purchasing this unit ensure you order the service valves as well as these are needed to clean the unit on a periodic basis. As this unit requires a 3/4 inch gas line, movement of all water lines and PVC work to vent and provide fresh air I hired a professional to perform the install. I am glad I did so as he spent a day to remove and install the new unit. In short, this unit works well and is a great value at the price point being offered by Home Depot. Yes, labor to install is more than a standard tank, but endless hot water with a longer warranty and space savings is worth it. May 10, 2016
Rated 5.0 out of 5.0 by Happy Customer My husband installed this in our crawlspace with relative ease. The directions were very clear. We are happy, two showers and laundry at the same time. I very rarely had a hot shower when we all had to leave at the same time in the mornings. We not only have enough hot water, the temperature is a shocking surprise. We were replacing standard hot water heaters every 6-10 years. These heavy monsters are very difficult to move, especially in a crawl space. I am hoping for a long life on this product. September 13, 2016
Rated 5.0 out of 5.0 by Amazing I am a diy type of person, that said I wanted my plumber to do this one. After 2 months of waiting I decided to get it done. No plumbing experience (some common sense) and about 3 hours, the old tanked water heater was out and this tankless was in. Searched online and turned the temp to 140 instead of the default max of 120. Ran it for a week at 140, then turned it back to the 120. Even the 120 comes out the faucet warmer than my old tanked water heater. Cut my gas usage in half during the summer when the furnaces are turned off. And now all 3 showers can run at the same time without running out of hot water in the first 5 minutes. All and all very pleased. August 7, 2016
Rated 5.0 out of 5.0 by Tankless hot water heater Home Depot's Customer Service was EXCELLENT when we reported a missing part and the manufacturer's lack of response. I cannot thank Home Depot enough. Our family is very happy with the end result!! August 16, 2016
Rated 5.0 out of 5.0 by Great Purchase- Efficient and space saving Space saving and energy efficient. Great buy! Price is worth it. July 28, 2016
Rated 5.0 out of 5.0 by Very Happy so far I decided to take this on myself for the installation. I've had plenty of experience with electrical work, PVC, and some iron pipe experience, so I wasn't totally new. But, its very doable for the more experienced do it yourselfer. The instructions were pretty easy to follow and installation went smoothly. Took several days only because I had to gather parts and work a full time job in between. Can easily be accomplished over a weekend if you have everything you need before you start. The unit started working immediately, flawlessly as soon as all the connections were made and it was plugged in. It is capable of delivering very hot showers if desired. Love it so far! April 28, 2015
Rated 5.0 out of 5.0 by Excellent product, great Home Depot shipping The water heater replaced a 13 year old tankless heater. It provides much more hot waterand and is more efficient than the Bosch it replaced. July 13, 2016
