Natural Gas Tankless Water Heater - ORBEK 100,000 BTU Up to 4.3 GPM Indoor Installation - CSA Certified On-Demand Instant Hot Water Heater 3/4" NPT Connector Size

So far working great, and one of the best things about it is that it turns on with minimal flow that my prior heaters of this gpm would not operate at. So we no longer need to have faucets at full blast just to get the heater to turn on. Also like that it had 3/4 sized water connections where as other heaters only do 1/2" size which limits flow especially when using plumbing like pex. The only negative is that it does take about a second longer to actually cut on once it detects flow compared to other heaters I have had, just makes it a bit longer to wait for hot water to start coming out. Otherwise, seems like a high quality heater, hopefully it will last without throwing error codes like I have had with these style heaters in the past.Keep in mind, these style of water heater do not need to mix with cold water like a traditional heater. You want to set the temperature to the hottest setting that you need out of the tap without mixing with cold water. then use the cold water to adjust down as needed. You do NOT need to set it to some high temp to then mix with cold water like you normally do with a tank in order to not run out of cold water in the shower. these are on demand so you will never run out. I see alot of reviews saying it cuts off when they mix it with cold water. likely they are having the temp up too high and mixing too much cold water with it causing the flow to drop down too much and causing it to cut off. this will happen with ANY of these tankless style water heaters. Especially in an RV where flow is often lower to begin with.

Well I surprised by the size and the amount of hot water I get. It is very easy to install. And for the price it fit my budget and gave me the hot water that is needed. I have had it for 6 months now and it works great. The quality looks good and it's very easy to change the temperature at anytime with a click of a button. Haven't had any problem yet. Very durable and looks great.

I’m excited this is my first tankless water heater. Was fairly straightforward to install. I had it done since I wasn’t the most experienced with plumbing lines. Got a feeling this propane heater is going to work wonders on my electric bill. Something’s I’ve found so far , system heats really fast but takes the lines about a minute to reach my outlet where I’m using the water shower, kitchen sink etc. once it’s there very hot. Did try reducing flow of water in shower and notice if you slow the gpm to much it does indeed shutdown and water gets cold. I’ve taken fairly long showers for me and water stays constantly hot. So far very happy. This will also keep me from having to use my 220 heater and it’s great for my supplemental/ backup solar which supports only 120v.

I’ve been on Amazon since 1998 and this is the best 3rd party seller I have ever encountered. After buying the water heater there was an issue with the igniter. I emailed this seller and got an immediate response on what to test and how to test it. If it failed they said send it back and we will swap asap.I did not have to buy their water heater again when I return this one. I chose to buy it because prior to purchasing the first one. I did some research and it seemed to be a very good in-line water heater for that price range. I felt good about my purchase. When there was a minor issue, I was not deterred so I thought I would purchase it again. Throughout the way, they remain in constant contact with me even when I didn’t. This water heater was installed in a home and while I was returning it, there was no hot water. I emailed them my situation and they received the water heater at 10 AM on a Tuesday. They credited my account by 11 AM that same day. I ordered the replacement that same day, and they shipped the replacement all in the same day. The new unit arrived two days later. I installed it and it has been operating now flawlessly for over a month. It’s a very good machine. I highly recommend this water heater and the seller. They really stand behind their product and their communication skills are excellent.

After installation, with all directions followed and all connections verified correct and without leaks. The unit was started following the step by step instructions. The water temperature was set and the water flowed, but the burner wouldn't start. We checked and rechecked every step of the setup and verified everything to be correct, but the burner still wouldn't start.I finally decided to return it and get a replacement in case it was damaged in shipment or something. Now the problem is, they didn't give me the option of getting a replacement while the unit is shipping back. I have to wait 2 weeks for it to be shipped before they will give me a credit to get another one. While I'm waiting my old water heater is leaking all over the floor and damaging the carpet and floor underneath. I'm not happy with this company at all.

It works great, exactly what it should do, easy to install, and a great price. What's not to love?

Just right for what I needed, pay attention to gallons per minute when purchasing. I use this for a shower and wet bar. It works very well I'm impressed. Installation was super easy.
