## Description

Ranein Tankless Water Heater, Outdoor Max 5.3 GPM, 130,000 BTU Instant Hot Water Heater - desertcart.com

Review: A bargain, but size the heater for your household usage. - My twenty year old 40 gallon (traditional) hot water heater finally sprung a massive leak, leading me to research LPG heaters that were available. My recollection is that the heater cost around $300 in 2005. The local big box hardware chains had heaters that began around 800 and seemed to accelerate from there. Since I live by myself, this seemed to be overkill, when I had the bright idea to look at tankless heaters. The chains had some that were even more expensive. Then, I checked desertcart. I found this 3.8 gpm / 80000 BTU heater on a black Friday price of $239, with a minor delay in delivery. For the price difference, I thought I would give it a try. I also ordered a HYDRO MASTER Tankless Water Heater Service Valve Kit (62.46) to provide fittings for the water connections. I waited a couple more days for my friend (Thank you, Andrew) to assist me in mounting and plumbing the unit in. His expertise, while not absolutely necessary, allowed me a two hour installation, with no leaks. He helped me determine additional parts necessary (PEX fittings, PEX hose, exhaust pipe and couplings available locally (around $120). (One caveat: when attaching the water valves to the unit, use teflon tape and teflon paste to seal. Do not apply too much torque when installing, it can be difficult to counter hold the connection.) All plumbed up, turned on the cold and hot water valves, plugged in the electric, turned on the LPG, no leaks. turned on the hot water spigot and the unit fired right up, I could not have asked for a better outcome. I noted on the outside of the cover, the date of purchase and the 1 year warranty. We'll see how long it lasts.
Review: Great quality water heater - The water heater works very well. It is small enough it does not take up very much space in our tiny home. We have hot hot water most of the year but once the coldest days of winter get here you have to slow the water down coming in so it can heat it sufficiently. The heater is very durable offers excellent water heating quality. We only have to slow down the incoming water for showers, sinks work fine full flow and I haven’t checked the washer but we have had it a year with no issues and we do have 11 people in our house.

## Features

- Fans Placed Underneath: It will be more secure in terms of safety, and no smoke backflow will occur. The blower has large power and can automatically adjust the rotating speed according to the change of external wind pressure and the change of water temperature to provide sufficient oxygen for gas combustion, ensuring full combustion and safer use. Low noise and longer service life.
- No Waiting Required: Unlike traditional tank water heaters, tankless water heaters eliminate the need for a 30-minute preheating wait time, allowing you to have unlimited hot water on demand.
- Easy to Assemble and Use: Uses standard 1/2" NPT water inlet fittings and 3/4" NPT air inlets for quick installation. Its compact size of 23.2"L x 14.2" W x 5.9"H takes up almost no space. If you have any questions about installation and operation, please do not hesitate to contact us and we will serve you wholeheartedly.
- Wide Application: 130,000 BTU high heating capacity and maximum 5.3 GPM. It is suitable for 3-5 outlet points, which can satisfy whole family. Equipped with Anti-Freeze Protection: Prevents the water heater from freezing and cracking internally.
- Note: If you encounter any issues, please contact us. In cold weather, if the water heater is not used for a long time, the pressure relief valve needs to be opened to drain the remaining water in the water heater. Not recommended for areas over 2,000 feet.

### ⭐⭐⭐⭐⭐ I love this water heater!!
*by J***S on August 23, 2024*

2nd edit!—— it’s been almost a year and want to say through the winter I was almost certain it was going to be broken with the water frozen even inside the house, we had issues with the gas company (propane) blot being able to come fill so we went without heat off and on all winter, we ended up just filling a 100lb cylinder every 2 days 😳 it was expensive. But during the times we didn’t have heat and inside froze my fridge broke, (water and ice don’t work) all shut offs busted when we got heat and water thawed. But the shut offs to this didn’t! And it didn’t break! We’re still going strong and still working properly 🙌🏻 Editing to update, it’s now been about 3 months and I love this so much! Bills went down about 100$ and it’s just perfect! I got this about 3/4 weeks ago it’s been installed 3 weeks or so. My dad installed and I was helping. It was easy to install and hook up. The packaging comes with everything basically, you need to hook up. I’m pretty sure we had to buy the shut offs. But either way it’s cheap and works great. I have 5 kids almost 6-11 years old plus 3 adults. So far no problems with it heating and keeping temperatures. It’s quiet and definitely space saving!!! So now I can use the bathroom closet instead of having a big tank taking up all the space. This is the propane not natural gas. Sorry for the long video review but wanted to let people to know some details cause I was hesitant my own self after reading some of the reviews. Questions for will it work or not work cause I was told by Lowe’s a few years ago I need a 9-11gpm for the people I have in household. It’s actually by faucets and the rating they have and how many you have and want running at the same time. So I bought all my fancy faucets (waterfall, rain shower head) etc from Amazon as well and they do take a good bit of water output so I just checked the output and f it, let’s give this a try. My main concerns was the reviews like “I got propane but it won’t work it’s only for natural gas” or “it leaks upon installation or after a few days” I’ve had it for almost 3 weeks and it’s been good to us no leaks nothing. I’d definitely recommend this tankless heater
