Don’t know how reliable this is for I just installed it. It work awesome easy to use. Was an easy install. Heats and holds the temperature well. Was just what I needed for my camper. Would recommend for ease of use and installation. Was a perfect fit for me also make sure you measure hole before ordering

Will never be purchasing anything like this or anything similar to this ever again as apparently this is not a warranty item, but you can charge a lot of money for a non-warranty item even though the box was handed over to us we had it professionally installed. They still will not warranty something that’s not working so it came defective. I spent a lot of money on a defective item that I now have to figure out how to probably spend a lot more money to either a get it fixed or be replaced with somebody else’s product that will warranty it. Trust me when I say I will never purchase this product or anything from this company and possibly Amazon again.

I am using it on my overland F250, it works like no other! the bets one I used to date

I purposely held off on writing this review until I had used it for a while. I live full time in my RV and my only issue was never being able to take a real shower. I purchased this water heater approximately a year ago, I was a little hesitant when installing it because I've not had much experience dealing with propane accessories but all in all it was fairly simple. For a year now, as long as there is propane in the tank I can take as long and as hot of a shower as I want. Why tankless water heaters aren't a standard item in every home is beyond comprehension.

Yes, the fit was perfect and it works great thank you

Do not buy this unit. Did not work right out of the box. It gets better. No customer support service from the company. No phone number no website support. Amazon did take care of me though. Garbage unit.

I recently purchased this because I liked the idea of unlimited hot water. When I took my trailer down to the dealership to have it installed, I was informed that I was better off with a regular water heater. I live in Montana, where sometimes during the winter it will get down to -50° F. Admittedly, this is only for a few days, but it is enough to destroy one of these tankless water heaters. If you are unaware, the concept is rapid heat exchange. The water flows through very small copper tubing and absorbs heat from either electric, or propane quickly. When not in use, there is no heat applied to this copper tubing. While it does absorb heat rapidly, it also absorbs cold rapidly. In extreme temperatures, below freezing, the water inside the tubing will freeze, expand, and burst the copper tubing. If you live in a milder climate, or do not use your rig during winter, and have it properly winterized, this will not be a problem. But, if you do use your rig in the winter time, or live in it year round, one good freeze and you're going to be replacing this heater. Not just this particular heater, but all tankless water heaters. Some of the higher end models do have an automatic purging system that drains the water when not in use, the 'bargain' models do not. I tried to return the item, and it said I had 30 days to do so. I had the item for 36 hours and I tried to return it. I was informed that it was ineligible for returns. Through a lot of tooth pulling, arm twisting and temper tantrums, I convinced Amazon to refund my money. I threw this heater into a dumpster because nobody in my area wanted a free, brand new tankless water heater. The young woman, from India, that I was speaking with kept insisting for me to take a picture of the issue. How do you take a picture of 'I cannot use it?!?!?' The item looked well constructed, nice design, and it came well packaged. I just didn't have a use for it. If I lived in southern Texas, or Florida I might consider buying it again. Anything north of San Antonio, I would not. I am not telling you to not buy this item, I am suggesting that you do some further research before you commit. I hope this helps.

Had a small issue when it first arrived but they did everything and more to resolve the problem after it was resolved I love my unit works amazing and provides nice hot showers
