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: 
NO! If the electricity goes out the intake and exhaust fans will not work. So regardless of the fact it is fueled by natural gas, it will not come on. Also the gas lighter is electronic so it won't fire either. This is the major downside of this type of unit over a typical tank hot water heater! However, never running out of hot water has it's benefits!! I love the unit !

Answer: 
Jack: The tankless hot water heater does need electricity to run, about 2 amps at 115 VAC. It's full of control electronics, mixing valves, blowers, and other electrical parts. It should run off a small generator, maybe even a good quality inverter.

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: 
Yes. In power vent, you are referring to a water tank with power vent exhaust pipe coming out the top and exhaust outside. That is exactly what I had and changed to this tank less model. This unit vents with pvc piping just like your power vent tank.

You will have to install a venting system for a gas operated indoor tankless water heater. It's not a big deal if the unit is close to an exterior wall. It uses PVC pipe so you don't need a chimney.

Answer: 
Depends on what you mean by "power vented". This is a direct vented unit, meaning it vents out the side wall of your house. If the one you have currently vents out a chimney (likely does) you will need to run the venting for it. Also power makes it sound like your previous one was electric, note this is a natural gas unit, not electric.

Rated 4.4 out of 5 by 87 reviewers.
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 Great Water heater, but not for space heating. I'm not a plumber, but pretty handy when it comes to DIY projects. I've installed this unit in my home now for about a month and it works great. It's very quiet. The unit only gets louder (fan speed gets higher) the more water you pull through it. It's rare that all three bathrooms in my home are pulling max water at the same time, so for me this unit is very very quiet. It's very fast and accurate. The hot water comes out at its desired temperature only a few seconds after water starts running through it, and the temperature stats pretty constant. I was abled to bump up the max temperature up to 140 F by following the instructions on a YouTube video. I was planning on using two more of these units to replace my boiler used for space heating, but being that I'm no plumber, I didn't realize that a "boiler" is different than a "water heater." This unit CANNOT be used as a "dedicated" space heater, and can only be used in combination as a water heater and space heater. I cannot tell you if the unit is good in combination set-up since I'm only using it as a water heater, but their tech support mentioned that if water entering the unit is above 120 F, the warranty is ruined and that the heat exchanger will most likely fail. So after doing a bit of research I purchased a tankless boiler for space heating and will continue using this unit as a dedicated water heater. One minor problem that I encountered (not the fault of the unit, but myself) is that the unit kept turning on and off very rapidly, and intermittently without any water demand. This was due to my improper installation of a portable water expansion tank that didn't have enough pressure. Make sure to provide the same amount of water pressure as the pressure on the supply side. My pressure gage was faulty wify led me to put only 40 psi instead of 60 psi. I guess causing the expansion tank to expand and contract, pulling and pushing water through the unit at a rate close to the trigger rate. Venting was easy. Pvc schedule 40 all the way to the side of the house through the ceiling in between two joists. July 12, 2016
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
Rated 3.0 out of 5.0 by Not sold on it as of yet. I have a week of use with this unit. My mind might change after seeing my utility bill at this point I'm not happy. It's a pretty expensive so so product. For The size of water heater I needed this was close in price. I did the install as well. For the extra parts it ran around 350$. So far I have had plenty of hot water. It was fairly easy to install. Just a bit time consuming. It did free up a lot of room. The down side: 1 it's not very hot. I tried reprogramming it several times you can see how on youtube, Didn't work I can't get it to go over 120 degrees. 2 it's loud I'm going to try some things to quiet it down some today. I can hear it up stairs and feel it vibrate too. Its Not horrible but not great either. 3 it takes a long time to get hot water to any place in the house, especial first thing in the morning. At first I didn't think it would bother me but it is starting to. Its a bit of a hassle to have to wait 45-60 seconds for warm water just to wash your hands plus you are wasting water so I end up washing them cold. I like to conserve that was part of the reason I got the tankless water heater in the first place. I will try and update after more time. July 6, 2016
Rated 4.0 out of 5.0 by Product Great - Overall Experience Disappointing The water heater arrived with a dented front panel and a loose bracket inside. The dent isn't a show stopper simply a disappointment given the amount of money spent on unit and not having the ability to drive it to the nearest store for another one in better condition (not sure about other HD but ours didn't stock this unit and it had to be ordered online delivered to our home.) The loose bracket inside was luckily nothing more than just that. Again, disappointing given the money spent and inconvenience of exchanging for another. Called the number provided by HD for install info and was quoted $4,800. Then she said $3.800 since I already bought the unit!?!?! I questioned if I was hearing her correctly. That's a ridiculous amount of money to spend on installation. My boyfriend was able to install by himself. It was smooth but time consuming. Haven't had any problems with the unit since we started it and so far very pleased with it's functionality. June 22, 2016
Rated 5.0 out of 5.0 by not a diy project Endless supply of hot water but installation involved making a couple of new holes in walls as we could not use the exhaust from the old hot water heater. It's pretty quiet and only heats the water that you use. I'm waiting on the first gas and water bills to compare to what I have been paying. June 24, 2016
Rated 1.0 out of 5.0 by Debockle Right on the box it states "same day installation". That's nonsense, would not happen. What does happen is a contractor will call to set up and appointment to SELL you a unit and the install it for 6,500.00 to 7,500.00 dollars. I paid 1300.00 for the unit and expected Home Depot to set up an installation. Uninformed sales rep's have no idea that Home Depot does not set up and "installation only", after you purchase the unit. Went to Sears paid 1,300.0 dollars there and that was with installation. June 7, 2016
Rated 3.0 out of 5.0 by Works but is slow to supply hot water This is a good system for someone who has a recirculating hot water system or who wants to use it for heating a space with hot water. When the unit is activated is blows air for about 5 seconds then ignites gas, it takes another 5-8 seconds for the heat exchanger to warm up, then since the outlets are at the base and not at the top, it takes a few more seconds for the hot water to transfer the extra distance (compared to a top discharge tank). So when I had a tank it would take about 10 seconds for hot water to reach shower, now it takes about 30. For sink, used to take 20 sec, now takes 50 seconds. So what I did was install a small 2.5 gallon point of use tank just downstream from this heater. Now I get the hot water more quickly, and by the time the 2.5 gallon tank is depleted, the big heater is filling it with hot water so there is no interruption. Best of both worlds. Recommend they design this feature in somehow. And put the pipe discharge on the top!!! Also, unit is a little noisy. I can hear it upstairs through the floor. I surrounded it within a drywall panel box to cut the noise down. June 4, 2016
