    • Great small heater, but learn from my mistakes
Review Image by T. Parry T. Parry
Great little water heater. I'm using it for a small studio apt. It's powering a shower, bathroom sink, and a kitchen sink. Word of warning: We thought there was a ghost in the wall because it would heat the water perfectly until the shower came on. Then it went to nothing. We did a ton of problem solving on this unit and were about to bust down the wall to make sure the shower was piped properly. Turned out that turning the output valve down to about half fixed all of our problems. You can either use a flow limiter OR just turn the output valve down. Note: the 8w unit is BARELY enough to keep the shower going. It works, but can not heat water for anything else at the same time as the shower. If you can go for the slightly larger unit, I would highly suggest if you're doing much more than just powering a sink. I would have in retrospect, but would have to re-do the electric. ... show more

    • My RTE 9 has been working for over 6 years

I got this to replace my RTE 9 that has been working fine for over 6 years since I installed it back on 11-1-2013 when I got rid of my propane tank. So I decided to just have this new water heater on hand whenever the RTE 9 quits working. Who knows, I might even get 10 years out of it. It will be very easy to just swap in this new one when the time comes. So I got rid of my propane water heater shown in the first photo. In the second photo the green double breaker in the upper right is a 30 amp 240 volt breaker for the electric dryer plug. I don't have an electric dryer so I removed this breaker and just tied it out of the way. I replaced it with a 240 volt 40 amp breaker in order to run the tankless hot water heater. There was a knockout in the upper right. The water closet is right behind this electric panel. There is only a sheet of drywall behind the electric panel. Only three wires to connect. Two wires to the breaker and a bare copper ground wire to the panel on the right. So the three feet of electric wire already attached to the water heater itself is all that I needed. The third photo shows the RTE 9 connected. I used SharkBite push to connect plumbing connectors. The work with both PEX and copper. I adjust the water temp all the way up in the winter when I'm taking a shower. Otherwise I have the temp dialed back a little. So I only run my hot water faucet almost all of the time without running both hot and cold at the same time. I live in a 14 foot by 52 foot singlewide by myself so this is a whole house water heater for me. I am really pleased. Consumer Reports said that tankless hot water heaters can clog but after more than 6 years I'm pleased with how this tankless water heater is working for me. Once it passed the 6 years mark I decided to just get another one and have it ready to go when the time inevitably comes and the old one quits working. ... show more

    • Pay for what you use and nothing more.
This warms the water for me very quickly and I don't have a big tank to worry about. Easy to adjust water temperature and when I am not using hot water this unit turns off. So you don't waste anything you don't use.

    • This worked fine for my parents in KY
This worked fine for my parents in KY. They have zero degree temps right now. Just the two of them. The unit cannot bring water up to 140 when it is this cold outside, but I will be honest with you, it was so easy for me to install for them, and "just works."

The product works fine. Be sure to review the electrical needs to choose the right power source for your needs.
