“We have not been able to get this unit working yet. The information did not say that this unit requires a 3/4 in gas line, while the old water heater only needed a 1/2 gas line.
The information did not contain the information that a new large 4" hole needs to be cut into your roof for a larger exhaust.
The information did not contain the fact that you need a new sewer drain for the condensate from this unit.
It will take years to recover the extra cost for all this extra work and plumbing. If you think that installing an instant hot water heater is easy and will save you money.
THnk again.”
I am not sure who is doing your installation, but there seems to be some confusion. First, all Rheem Natural Gas and Propane units will get enough gas pressure off of a 1/2" gas line or larger. It is a 3/4" connection at the unit, but will get enough pressure from a 1/2" line.
In regards to venting I checked your order and you bought a high efficiency condensing unit vented with regular schedule 40 PVC Pipe, either 2" or 3" pipe for both the intake and exhaust depending on the vent run. You ordered the concentric vent kit for 2" PVC pipe, so I am assuming you knew what you were ordering, but the concentric vent is a concentric, so it allows for both intake and exhaust and a single 4" whole out of the sidewall or ceiling. If you were using 3" PVC the concentric vent would be 6" diameter.
In regards to a sewer drain that is also not necessary. All natural gas and propane tankless water heaters will have some condensation. You can use a drip drain, but you can also use a drip line that runs to the dirt or a collection system such as the tankless water hater pan with CPVC connector that can be included with the unit. Lastly, all of this information about venting, gas line and everything else is clearly stated on the product page, and spec sheet. We are also happy to answer any questions someone may have prior to their purchase.
I checked our phone records and we have never received any phone calls from you, not before or after your order; nor have we received any emails with questions, or concerns. I am glad you left this review so that we can help get them resolved. That said it sounds like most of your concerns are misunderstandings. You may need to find a more qualified installer as again a 1/2" gas is OK, you bought the vent kit that requires the size exit whole you have described, and you do not need special drain.
Please call technical support at 1-800-432-8373 if you have any additional questions or need support. We want you to enjoy your water heater and get the benefits of the built in recirculation pump.
“The water heater and optional accessories were delivered on time and without damage. Everything fit together perfectly and completely met my expectations. Great job!”
“I installed my tankless water heater and it's a blessing. Usually with 30-45 seconds I have hot water. Haven't had any problems to date and don't expect any. Thank you for the great hot water heater.”
“This is the best investment I have ever made. Hands down!
The unit is fantastic. Easy installation. Instant hot water on-demand. Never run out. I can have 10 people taking showers and baths always plenty of hot water not like in the past, before I purchased the unit. Thank you Rheem and thank your workers for a great product”
“WE ORDERED A HEATER THAT WAS OUT OF STOCK, SO IT WAS NOT SHIPPED AS PROMISED .
RICHARD EMAILED ME WITH A NICE NOTE TO TELL ME THE HEATER WAS NOT COMING. WE REORDERED WHEN THE UNIT WAS BACK IN STOCK AND GOT THE UNIT QUICKLY. HEATER HAS BEEN PREFORMING WELL.”
“My experience with Tanless Water Heater Depot was excellent. They delivered a superb product, exactly as listed, free of damages & defects. The communication was professional & their customer service was fantastic. I highly recommend them.”
“Only had it running for a short period of time but there are no hiccups so far, I did receive it with a damaged front cover but after 1 phone call I had a new one within a couple of days. I would recommend this product!”
“This thing is awesome....endless hot water is a necessity with two teenage girls.
I've had it for 10 years and it still keeps working, however I bought a second just in case (and because there is a $300 Federal tax credit applicable for 2021).
For those new to this, you will need to also buy valves for input and output so that you can flush the unit to remove any mineral buildup. You will also need a cheap pump (total prob an additional $150). Need to run white vinegar through the unit about twice a year to remove mineral buildup...takes about an hour.
The only complaint here that prevents 5 stars is that the unit will flash a digital code that means you need to flush/clean the unit....but Rheem doesn't give consumers access to clear the code. They want you to spend money on Rheem maintenance I suppose.
There is a way to do it but you have to remove the cover and press some buttons in the right way on the circuit panel. The flash code is an annoyance that never goes away if you don't clear it but the unit will still operate fine.
In hindsight, I would check and see if the manufacturer provides codes AND a way to clear them from the digital panel without having to open the unit.”
Thank you for your review and your business. It sounds like you are saying the unit you have had for 10 years, not the new unit you bought from us, you have had some trouble clearing the code after it has been descaled? I am sorry about that, if that is the case. First and most importantly that will not be an issue with the new unit. The new unit you recently bought will let you know when scale is starting to build up, but once flushed that will no longer flash. Also, there is no such thing as spending money on Rheem maintenance. Rheem technical support is free for anyone that owns a Rheem water heater. You would call technical support at 1-800-432-8373, give them the serial # of the unit, and even if it is no longer under warranty, they will assist you and provide technical support. However, if the unit needed to be flushed or something like that, and the owner did not want to do it, the owner would have to hire their own plumber. There is no such as thing as a Rheem installer, or plumber. Rheem is a manufacture only. They do not work with any plumbers or installers directly when it comes to tankless water heaters.
“Water heater shower up amazingly quick. My particular install was a bit complicated, but once it was up and running it worked great! In use for over a year now with no problems at all. And unlimited hot water!!!”
“Product arrived in a timely manner and was set up by a local handyman. He had to speak directly to the Rheem technicians because something about their set up guide was incorrect. The Rheem techs were easily contacted and very helpful.”
“Super Quick shipment and arrival of Water Heater. Prior to purchase I spent at least 30 minutes on the phone with one of their employees. He went out of his way to answer all of my questions and to ensure I ordered the hot water that best suited my needs. Unless you have some plumbing experience I highly suggest hiring a pro to install a tankless water heater. They are much heavier than you would think and not only require basic pipe work and soldering but also specialized venting. My son in law and I both very experienced in home projects removed the old water heater and installed the new tankless in about 3 hours, which included a trip to the hardware store for plumbing parts. From my personal experience I would highly recommend dealing with this business. Thank you”
“Purchased this unit for my folks house in New Mexico @ 4375’ el. The altitude correction on the main board is exactly what was needed and few others provided. Next item was installation on west outside wall, the old Bosch unit never could operate consistently with the wind. This unit does, never tripped off or faulted in any way. Completely reliable. Last but not least was the service provided by Richard in getting my order processed and shipped the same day. Thank you again.”
