My gas water heater went out and I was flipping out because to replace the tank style water heater was outrageous right here at Christmas! I ordered this thinking it will do until we can afford a new one. I will never spend money on another tank water heater again. We ordered this tankless for around $175 and boy was it worth the money.. a top quality water heater! Even if it only lasts a year I cannot complain! It is worth every penny and more. It doesn’t have to be hard wired for the electric parts which was a plus for us. We already had the venting hole in the wall so that made it easy… I would say if you don’t have the exhaust hole already that would be the only hard step for install. The rest was a breeze to hook up! And since I am getting older not having to get in the floor to figure out what’s going on with a tank water heater is another plus! It automatically turns on when you turn on the hot water. Super hot water.. we have it set on 120 and you can turn it up higher than that but it is not needed. Our water pressure is weird and sometimes low but we haven’t had any issues with not getting hot water so far. Would definitely recommend this water heater.

Water flow is great. Has a hard time heating from 73 degrees to 140. Had a leak inside but i was able to fix it the fittings are not what i expected.

This unit will not handle multiple faucets. It can barely keep up with one shower and the hot water comes out very slow and takes 23 minutes to fill a average size bathtub with 115° water and when you hardly move the handle on the shower for temperature control it drops from 115 down to low 80s and 70° water temperature because the water heater is shutting off and then firing back up. Don’t waste your money by a namebrand.

Was able to get this connected with no issues. I had pex b plumbing prior so I just used that to connect the water. This replaced a 10 gal electric water heater because its now winter and solar energy is scarce. So far so good. Ill check back in on its performance in a few months. Badically hot water is pretty much instant and im happy with this heater. Was able to mount it with no issues. I used a wall thimble i had for a previous off grid project that I never used. One thing I will add. When we first purchased this heater, it stated it was amazon returnable within.39 days. When we checked back, the return status changed so keep an eye on return options at the time your purchase if you think you may have issues or this isn't the right unit for you.

This was a great purchase. I wish I would’ve gotten one years ago. It was easy to set up and program. It delivers quick hot heat to everywhere in my house. Can’t wait to see how much my gas bill will go down. This is definitely a great purchase.

I purchased this tankless water heater to add to my outdoor shower and it has been such a great upgrade. I really love that this Portable water heater runs off of propane, It was perfect for the campsite shower. The installation and setup of this heater was so easy. The hot and cold water are easily adjusted with the simple turn of a knob on the front of the heater. I was really impressed that this portable heater came with multiple shower heads. We're able to just hook up the shower head for the shower and get right to using it. The pet head will also come in so handy come spring time an Fido is playing in the mud at the campground!

I've used this for a week in an off grid cabin. It will raise the water temp from 32 f to 116 f and not all instant hot water heater can do that... It lights every single time consistently. The water temp stays absolutely stable......Seems extremely reliable!!!!! 5 stars!!!!
