Burl P. Bolle: Customer service was awesome and resolved this issue within days expediting shipment. Liked hot endless water while it lasted. Disliked unit broke after 11 months. Displayed error HH which means output temp is too high. The Manual’s troubleshooting solution is unit do not work. Turns out the output temp sensor went bad. I know a bit about electronics so those of you that do here's some more info. I checked the electrical resistance of the good output and input sensors and they read about 4.6K Ohms the bad one read under 1K if I remember right.

¤♤♡◇♧□○°¤♤♡◇♧□○°: This takes some preparing but when connected to 2x40amp breaker and with the 8 wire it runs amazing and gives instant hot water. This works wonders in my 33ft camper. It keeps constant water for showers or washing dishes or cleaning. It works better then we need in this little camper. It's easy to install but I recommend making sure everything is correct because messing with electricity is dangerous. A must have

Jeffery weston: Will not heat up water stays cold if I can't get it working I am going to send it back ! Well I had a a.c. heating guy come he said everything had power and water but the thermostat was not working to tell the tankless heater to heat the water , so I had to send it back and get a small tank water heater .

PaulPaul: The 18kW Rinkmo heater I purchased for my southern Florida home appears to be well made and well designed.

These are some issues I have with the product and the documentation.

The printed and web documentation has zero mention about external valves that may be required or appropriate for the installation. For my installation I incorporated a 3/4” tankless isolation valve kit w/ a 3/4” over pressure / over temperature valve, per the local requirements.

The copper plumbing for the 3/4” safety valve slopes downhill to the exterior of the structure, w/o any valves, w/o any reduction in size, w/o any trap, ending at the specified height above ground, all per the local code.

The tankless heater parts included four sheetrock wall anchors w/ screws for mounting. There was no way I was going to attach using wall anchors. My installation in the closet next to the unfinished bathroom permitted me to add horizontal 2x4 boards between the vertical studs. Those horizontal boards accepted the right side mounting screws and the vertical stud accepted both left side mounting screws. This is a very solid mounting method. This placement permits the...
