Eccotemp 45H-LP 6.8 GPM Outdoor Propane Tankless Water Heater, White

For the money, this thing is awesome. Thanks to an Amazon screw up I bought this in crunch time because they sent me a Rennai for natural gas instead of propane. Honestly this was the only propane tankless heater that would ship quickly so I bought it despite all the rotten reviews. Lo and behold I installed it in about an hour and it worked great right out of the gate. It dials up to 140 degrees and takes about 1 minute to get hot water to the nearby faucets. Water temp is every bit as hot as a standard hot water heater. With a cost difference between this and a Rennai of about $300 bucks, only time will tell but for now, I'm completely happy with nothing bad to say!

I got this for my 1000 sq ft house about 3 months ago. The plumbing had to installed and then the inside of the house finished. I didn't get to run or test it until about 3 weeks ago. I was excited to test it, though nervous about the Chinese made heater.At first run, it came on when we turned on the kitchen sink. It ran as advertised heating the water right to 120. Then we tried the shower and and it no longer turned on. I tried the bathroom sink and it came on, but only on nearly full power. After a few hours, the kitchen sink no longer turned on the heater.There is a flow meter inside the opening to the heater that controls when the heater is turned on. The manual with the heater states the heater will come on at .75 gallons per minute flow. I was pulling 1.4 gallons per minute out of my kitchen sink and that was not turning on the heater. I called customer service and explained the problem. The service agent said she had “just had a call about the same model” and she advised that person to replace all their fixtures for flow problem. I was told my plumbing was the culprit. I explained that it should have come on over the .75 flow minimum but she disagreed. I explained that new faucets are only allowed 1.5 gallons max and how could I obtain this flow.By that afternoon the heater was no longer even working. I had all three faucets turned on the same time and the heater did not turn on. I submitted a ticket online since they no longer answered the phone. That started two weeks of hassles. If you are not technically inclined or have to pay plumbers or electricians to install, I recommend you never buy this equipment. Here is an excerpt from their troubleshooting email.If there is no error code and the unit does not come on when the HOT water is turned on. This means that the flow meter is not sending a signal to the computer which starts the machine. 1st to fix this you want to locate the flow meter at the bottom right on the inside of your heater. The flow meter sensor will have a white, plastic piece attached to the front of it, with a set of different colored wires coming from the computer board attached to the top of it. The flow meter sensor has red black and yellow wires coming out of a black sensor that is screwed to the flow meter.2nd check the wire connections; follow the wires to where it connects to the computer board. If both were connected you will want to remove the flow meter. Then, you will need to remove your water inlet on the outside of your heater, at the bottom right side. There is a metal clip that holds the flow meter sensor in place inside the heater. Remove this metal clip, and blow through the meter- it should make a zing sound when the little fan inside spins. Reinsert the flow meter sensor, re-attach your water inlet, and turn hot water on to see if this resolves the issue.If the display shows two squares rotating up and down. This pertains to the 45H only. 1st push the power button. 2nd If the unit has been in operation for a while and all of the sudden the squares begin rotating. This means power was lost somehow while unit was running. 3rd The flow meter wire is loose on the computer, or the connector where the two wires connect between the computer and the flow meter are loose. 4th The remote itself may have a short, or the power cord going to the computer one of the prongs may not be making a good connection threw the connector or the computer.Regardless of what the error code is; take the two front screws out of the computer board and it will slide out. Pull the inserts that are lined up along the front of that board and put them back in one by one. Plug the unit back in and see if this solves any issues.This went on for 4 emails. At one point I had to have all the plumbing removed from it and then turn it on to test. Each of these emails cost time and money. Finally they called me and asked me to connect all my plumbing to the pressure relief valve. I finally told them no way was I going to connect my plumbing to the safety devise required by law to have nothing plugging it. I was put on hold and eventually hung up on.The whole time I had been begging for a part to try to fix it. As many times as they had me take it apart, I could have tried some new part like a flow meter or circuit board. Instead they gave me a laundry list of suggestions that in no way fixed my problem. I even told them the flow meter did not make a consistent zing as reference in the email above.Finally they sent me and email telling me to remove the heater and send it in for service. If it was within the 30 days of purchase, they would do this for free. I guarantee it no one will ever fall within this 30 days with all the run around they give you with diagnostic emails.I finally called it quits. After all the time and money wasted troubleshooting this heater, I had to give up. In no way was I going to invest any more time on this heater.If all you're going to do is heat a swimming pool, this might be a good heater for you. Don't bother plumbing anything larger than ½ inch since all the piping inside the unit is 3/8 copper or smaller.

Purchased this new model to replace one that froze and ruptured when it got down to 22 degrees. It is 23 degrees here right now and I just had to unthaw the unit. Luckily I don't think it was damage. Do not trust the built-in anti freeze protection. I have had trouble with the control panel intermittently working and the unit is pretty flow rate sensitive.

I have had this for one month now and it has worked flawlessly. I am super impressed and with temps down in the teens and no freezing of the water heater and its mounted unprotected outside and just plugged in.

excellent product. does not freeze and tells you when propane is too low to work. flashes an error code easier to set temperatures and love the internal heaters. so far I have bought three different tanks and this one is by far the best

Works very well as a swimming pool heater for 1800 gallons. From 70 degrees, it will heat about 9 degrees in one hour and then 6 to 7 degrees the second hour.Allows us to use our small pool many more times throughout the season.

I bought this unit in 2016 to install on my Alaska Cabin utilizing LP which I only use for 3 weeks out of the year. Didn’t get to install it until summer of 2017. Seems like it would fire up and work for a little while but then came the E1 errors (ignition system failure). Because the E1 error comes and goes, I don’t know what the issue is. It would work through one shower, then stop working and get an E1. Sometime it would come back on and work through an entire shower and other times the E1 error would prevent firing up again. If I tried the next day, it would work for a shower or two but then the E1 would creep back in.I’ve got the right regulator, 11’ WC, 160,000 BTU, changed the hose from 3/8” to 5/8”, changed the tank, all without getting it to work consistently. I’ve even tried to soak the tank in water to warm it during use.I’m starting to think that the other ratings are from the China factory pumping up their products as noting can have ratings so diverse. 36% 5 star and 46% 1 star?It’s now the summer of 2019: whatever the case, I cannot get this unit to work effectively when needed and will need to turn it into a shooting target, if it’s not resolved soon.

Works Great!!!
