    • I don't understand all the bad reviews for this tank
I don't understand all the bad reviews for this tank. It works perfectly for me! I have a feeling most of them are because of misunderstanding how a tankless works. The best thing to do is run hot water full blast in your shower and adjust the temp on the unit to whatever you like. Another words don't mix any cold just hot. I like the remote because you can adjust the temp right there in your bathroom, or where ever you install it. ... show more

    • Garbage!!!
Do Not Buy this garbage! This item doesn’t work, it gets the water hot, then it sends error codes and immediately gets cold! Avoid this particular tankless water heater, definitely not worth it! Buy a Rhem. Seller would not refund my money for this item, had to contact Amazon direct for a refund. Avoid this item like the plague. ... show more

    • Install was easy, heats up water like its supposed to
Install was easy, heats up water like its supposed to. Been using it for about 3-4 months now with no issues. I do not have the 'flow' issues that other reviewers have mentioned. I would absolutely get this again. The idea is to have the temp maybe a little hotter than you would use. not 130-140 like a tank water heater. That saves water and gas. Why have it at 140, just to cool it back down to 110. ... show more

    • Stay away from this company
This tankless hot water heater has been constant problems for me, very low quality. Ended up replacing it with a reputable brand. Just trust me on this, you do not want a tankless hot water heater or any appliance that you can not easily find parts for locally. I struggled to get tech support for their products, plumbers have told me they are basically useless. The first repair you do (which happens quickly) will either leave you without hot water for a week+ or you will spend more than the cost of the hot water heater overnighting parts that will arrive late anyway. Just save yourself the headache and money and buy a local big box brand. ... show more

    • thankless tankless
This was my 1st attempt at installing a tankless water heater. Man, did i have a lot to learn! I have both electrical and electronics backgrounds with construction experience. 1st: Tankless heaters are flow dominate. They come on and operate based on water flow. Mine did not operate correctly because of low water flow. I had allowed pipe dope to get in the system which restricted flow. I also had several faucets with clogged diffusers which limited flow. At first it would provide hot water then get cold, if it came on at all. After cleaning the heater filter and making sure there were no other flow obstructions, it works fine. 2nd Traditionally we heat water and add cold water to obtain the temp we want. This causes a problem with tankless because as you add cold or back off the hot you reduce flow which can shut off the heater. Select the lowest temp that suits you and you'll need less cold and won't have to reduce the flow. Overall easy to install if you follow instructions. Get the valve kit to flush it as you'll need it later. Venting has unique requirements, follow the instructions! Will not handle multiple showers or large activities at the same time, get a larger unit if you need more. 3rd: It uses water like a leaky sieve! It takes about 30 seconds to get hot water each time and will have a cold water sandwich often after shut down and start up a few minutes later. So you let it run untill you are sure you have hot water (using more water). Support for this brand (live) is non existent from the manufacturer. They dont even have this model in their support section. Conclusion, it works. Shop around for the more advanced brands if you are going to have more activity than I (one person) ... show more
