Noritz Replacement Heater Dec 14, 2016

i installed two of these in 2008. had to replace one after 6 years the other after 8 years. the only reason i replaced with Noritz was the supposed ease of replacement with the same heater i.e. all piping was supposed to line up...NOT SO! I had to redo piping which cost me an additional $200 because the piping did not line up with original heater. Also i should have been able to get a longer life with original heaters.

It Does Not Work Apr 20, 2016

Installed the unit, turned the power on, getting flashing on/off light. Remote cannot find out the problem.

Great Unit, Love It Jun 09, 2016

Installed it in a 16ft x 20ft building. Works extremely well. Keeps the building at 50 degrees when unoccupied, then heats it up to 70 degrees fast when occupied.
