    MY N-120 TITAN TANKLESS QUIT MAKING HOT WATER AT 15 MONTHS OF AGE. IT MADE A "SNAP" SOUND THEN NO MORE HOT WATER. IT IS NOT THE BREAKER. THE UNIT HAS POWER, BUT DOES NOT PRODUCE HOT WATER.

    Mine is also about the same age, and has quit working. I opened it up and one of the wires that goes to an element burnt/melted. You can order replacement parts, but i think it'll just end up breaking again.

    Does anyone have the wiring diagram for one of these N-120's.
    Need the wiring diagram for a Titan N-120 tankless water heater. I had to take mine apart to clean deposits out of it. I need to know which wires go where on the control board and which wires go where on the heating elements.

    It sounds like the thermostat, Niagara has a tech line that you can call. Mine is over 8 years without problems. It also sometimes depend if you get a pro to put them in.

Pressed,
I agree, Niagara needs to solve this problem. I ended up sending my unit back to them to have all the electronic components replaced for $50. When it gets returned to me I'm going to open it up and make sure they replaced everything. I'll probably also replace the wire with a larger gauge as you suggested. When i emailed the company my concerns about this problem, the rep that answered my email stated he had never heard of a fire or anything of that nature occurring with a Titan, in the 7 years he's been working with the company. And "it sounds like a fluke and am confident it will be repaired properly". Here's the phone number he gave 305-876-9010 for me to discuss my concerns personally with someone. I think i'll email him back and referr him to this site as well as others i have come across while researching this problem. Seems like 3 years of regular use is about the lifetime of the heater.

Same thing happened to me. I'm replacing the element and upgrading from 12 gauge wire to 10 gauge. If you do this make sure you get wire with 105C rating. I'm still waiting on the element so I don't know if this is a long term solution. Sounds like a flaw that needs to be fixed by Niagara.

Incidentally I bought mine over 3 years ago. I have another that I will inspect shortly to see if it has similar problems.

Niagara has a tech line that you can call, it sounds like just a matter of reseting the thermostat. I have had mine for 7 years, it also depends a lot if you get a pro to put it in.

I have had mine 3.5 years and worked great until then. Lost all lights yet had power going to unit. Trying to get schematic. I suspect the SCR's. They are cheap to buy from their parts list. Thanks for phone number. I will ask them what give the power lights to the Green light and the red SCR lights. I had bought a spare just for this. Didn't want to have to be without hot water.

Same thing here..only got a year and two months out of mine...if you are reading this and considering this unit...dont mess with it...u wont get 2 years out of the unit..please read everything about it on the net..u will see only about 15-20 percent of the people have anything good to say about it. the company has pitiful to no service, the heaters electronics are warrantied a year and that seems to be about the life of it..they say a 10 year warranty on the case..i would give a 10 year warranty on a piece of tin, too- wouldn't you? i read a lot of negative stuff about it, shortly after i installed mine. I didn't want to send it back because the wife and kids were so happy with the endless hot water and it took 75 extra dollars to change over from the tan. after it took two weeks to convince the wife this was the way to go, I didn't want to admit- I was having my doubts a few weeks into it, after reading some blogs on the net.I finally forgot about the negative and convinced MYSELF,"we would get better service than everyone else if we took extra good care of it and did'nt crank it up".. well a year and two months to the day- here it is- I am without hot water and searching the forums for a clue how to fix this POS. these people here that got three years out of theirs are doing great compared to everyone else.

I JUST INSTALLED A TITAN N-120 TANKLESS HOT WATER HEATER AND IT WORKS FINE FOR ALL THE SINKS BUT IT IS NOT PROVIDING HOT WATER TO THE SHOWER AND THE WATER FLOW HAS DIMINISHED IN THE SHOWER AS WELL.


It's doubtful your water heater unit is the problem. There is simply no reason for it to only work on sinks unless some how the pipe size was drastically reduced coming out of the unit so sinks got plenty of hot water but the shower does not. Take a second look at the installation. The pipe should not be less than 1/2" coming out. If that's OK then consider a clog or valve problem.
