“I'm at a quandry of what to do?? About once a month or about every 15 showers the hot water stops... there is Nothing I've done to prompt it.... like about 5 minutes into the Normal Regular, Nothing Different Shower, the Hot water stops and cold water starts!!! The next time I use the shower, there is nothing amiss in it's function. I've only showered in one location that its happened in... ie. don't shower much in the other shower in the house and it never happened there.
Also it takes it near 2 minutes for the water to get hot it the very beginning, but I've had that explained that there is alot of pipe footage to travel and it takes a long time.... However, the distance is not 5 foot longer than using the hot water heaters of the past that Ive ever had in this house and I've lived in for 37 years.
Thanks for an explanation, or suggested action I might take to improve my experience with the Tankless Water Heater.”
Hi Debbie, The issue with the hot water stopping in the one shower from time to time sounds like a classic cold water sandwich. This and the other issue with it taking longer than you would like to get hot water your main shower would be solved by adding a recirculation pump. Recirculation pumps recirculate water through the system so that there is not cold water in the line that has sat and cooled after previous use. This will prevent cold water sandwiches and allow you to have instant hot water. The Rheem recirculation pump kits can be found here: https://www.tanklesswaterheaterdepot.com/tankless-water-heater-recirculation-pump-kits-and-accessories
“I am new to tankless water heaters. I've always had "well" water and was afraid of mineral build-up, and I have to add, a skeptic that this unit could supply 2 showers with adequate pressure.
I recently added a new Springwell water system, including a Spin-down filter, iron and Magnesium filter, and a salt-based water softener. Mineral problems were eliminated. We all have been thrilled with the performance of this unit! No noticeable change in water pressure at the shower, even with two running. Installation was easy, hiring a plumber to hook up the gas and water lines. Venting it myself.
Rheem's helpline was horrible, my unit kept shutting down with an error code, and no one would listen to me about my venting being correct. They would just parrot back what was already in the manual. Turns out we found a loose wire on a sensor, plugged it in and it's run perfectly since. I am glad I got rid of my two, 40-gallon tank-style heaters. No flu pipe, no water being heated while we are away, and a huge space saver in the basement! Water Heater Depot was quick with delivery and helpful with extra parts.”
“I had a great customer service experience when I asked questions about which tankless water heater to purchase. The one I purchased ended up being the perfect size for our house.”
“Thank you for the opportunity to review Recirculation Pump.
In a word, I failed.
That's why I'm not using Recirculation pump.
The reason is that the water pressure from hot water drops when the recirculation pump is operated, making it uncomfortable.
I would like to know if there is a way that the water pressure of hot water does not drop when the recirculation pump is activated.
Thank you.”
Recirculation pumps recirculate the hot water prior to hot water being used, so that when you wash your hands or take a shower you have instant hot water. Once the cold water from the previous use has recirculated it would not need to activate again while hot water was being used. However, I may not being understanding the issue. I have checked our records this is the first we have heard of this from you. That said you can check the other reviews of the recirculation pumps and see people really like them. The review requests go out automatically to all of our customers about 90 days after their purchase, and this is not something other people using a recirculation pump have reported, so whatever is going on with your pump it is due to some sort of installation or other issue that can be resolved. Please contact TACO technical support at 401-942-8000 and work with them to get the pump working properly. If it is deflective and needs to be replaced it will be.
“Richard, who runs tankless water heater depot, was great. He helped me confirm the product I was purchasing, what is available and responsive, both by phone and email, and shipping no product properly. When there was a small issue with one of the accessories he helps to process the warranty immediately. Can’t recommended service enough!”
“Came in dented and ridiculous looking on the exterior…I was told I could purchase another cover and pay shipping. Not happening for a brand new unit that the distributor or carrier damaged.
My Response to an email regarding my review. They clearly didn’t like the negative review, but won’t allow me to respond back easily.
The box came in that way. I even told you that the box was damaged. If you are in fact, the person I emailed back-and-forth you totally disregarded everything I had to say about it. You are more than welcome to post to reply to my review, but my review stands. I currently have a dented hot water heater, on the side of my house. And no, I had no reason to open it up when it first came in, as I was not installing it for a while. Perhaps you guys should be better with your packaging.”
Hi Tiffany, I just looked up your order and read all of the emails. You sent an email after the unit was installed, and you had the unit for more than 30 days already, saying there was a minor dent to the replaceable front cover. I told you I was sorry to hear that, because the unit has been installed and you had in your possession for more than 30 days we could not file a UPS claim, but that we did have replacement available. Even though you did not opt to pay the extra $15 to have the unit double boxed and padded, the unit had been installed, and you had it for more than 30 days I offered to provide the replacement cover at our cost which is $48, and split the cost of its shipping with you. There was some back forth, but end with you saying you were sorry for being rude, that your renovations were stressful, that you had some other issues with other appliances you had ordered, and you would not be needing the replacement cover. I am sorry for the difficulties you faced while renovating. I am glad to hear the unit is working well for you, and if you change your mind as I told you back in September if you change your mind the replacement covers are available and that is an open offer on the cover and splitting its cost of shipping with you.
“So far, so good. Winter will be the test, when the unit will be sending hot water to the HVAC air handler that heats the small apartment in which it is installed.”
Hi Charles, thank you for your review. This was actually a company of review of our online stores performance as far as your experience shopping with us, it looks like you also left a product review, which is the same review. That said we need to let people reading this know the unit you bought the RTGH-84DLN-2 is a standards tankless water heater for domestic hot water only. It is not a boiler, and it is not a combi tankless water heater boiler. It is not made to provide hydronic radiant heat. Doing so voids the warranty. It is for showers, baths, sinks and so on only. There are combination tankless water heater boilers that provide both domestic hot water and radiant heat. These units from Rheem start RCBH and can be found in the Combi Water Heater Boilers section of our website. Standard tankless water heaters are not boilers, and they are not made or warrantied to be boilers.
“I purchased this hot water heater to supply hot water to a cabin sink and an outdoor shower in a semi remote property in Alaska. Our well is 220’ deep and the water is very cold. It is installed in a space that is protected from rain but still outdoors. This heater has worked flawlessly. A bit on the expensive side but we’ll worth the investment. It’s only downside for real remote areas is that it requires 110v power (instead of batteries). I’d recommend it to anyone.”
“Love my Rheem tankless water heater. For the first 4months of use in a 3 bath home with 3 people we used 17.7 pounds of propane! At this rate it will save over half of what the electric tank type cost us!”
“Works perfect for our double sink upstairs vanity. We save a lot of water as we do not have to let it run to get hot water. We've had it in use for about a month and it has worked great!”
