Titan Tankless Water Heater Installation help! [Merged threads]
Let me start by saying I am a novice with this installation and I appreciate any help. I purchased a Titan N-160 from TitanTankless.com and am in the installation process. The Titan unit has 1/2 inch threaded inlet and outlet and with my old tank I have what looks like 3/4 inlet and outlet. I want to put in a sediment filter that is 3/4 to keep sediment out of my new Titan. I also want to put in a ball valve on both sides of the Titan as well as a pressure relief valve on the cold side to protect the filter and plumbing. My question is what is the best way to install. Do I put a compression fitting at both the inlet and outlet to adapt the size for the Titan to 1/2? I have not yet bought the pressure relief valve but do I need 1/2 or 3/4? Should I place the filter on the incoming 3/4 line then place a compression fitting to change to 1/2 then put a 1/2 pressure relief valve in front of that and than put another fitting on the output line of the Titan to run the 1/2 to the 3/4 line that goes into my home? I am out of work and can't afford a plumber. My buddy will do the electrical so I am set there but can someone please tell me the best and most efficient way to do this? A 12 pack of heineken to anyone who can figure this one out. Thanks for any advice to get this right! Hi, Let me start asking you before you hook this unit up that you researched all avenues? Just a note, that unit looks like it shows a 70 amp breaker. Is your panal large enough to handle that? The electricians will chime in on that one. Geez you know what size wire you will need $$$$$. The breaker itself $$$$??????? The good thing is you are in FL, so the temp of the incoming water is warmer, then say the average in NJ which is about 55F. Now at a 2.5 GPM shower the unit will heat to a 44F temp rise. Add that on to your incoming water temp, say mine at 55F. 44 + 55 = 99F. Who takes a shower at 99F?? No one, so what do you do? You need to turn the temp up at the unit, right? Then when you turn the temp up your gpm go down to say 1.5 gpm just to get hot water. The unit trys to compensate and reduces flow. And God forbid someone uses a sink while your in the shower. ( Not trying to offer religion on this statement....) Just trying to show you what can, and probably will occur after you install this unit. I have seen so many unhappy customers with gas units let alone electric. The only electric unit I saw that somewhat worked well had three elements in it and had three seperate 40 amp breakers. ( Just a comparison ) I dont even recommend gas units let alone electric. If after you read this you still want to hook up , yes your below install sound about right. Just dont have the relief valve in a position where the valves you install will isolate it. The correct thing to do for your saftey is to get a permit. I am sure its the law in your state, and too many people try to circumvent this little detail of the installation process. OK done rambling........ The unit specs for reference. They dont tell you much info here. SCR3 N-160 Titan Tankless Water Heater, Tankless Water Heaters Mike NJ Would suggest you make a separate post over in Electrical - A/C D/C as Mike suggested. If you currently have a 100 amp main panel there is a good chance you will need to upgrade to a 200 amp panel even if you have gas for your other main appliances. Even a 200 amp panel might need upgrading if you have an all electric home with no gas appliances. You may also need to inform the electric company about the load increase. Are you having a real electrician not a handyman install it or will it be DIY? Already have installed the electrical on my 200 AMP panel and no issues with that. My home has a 3/4 incoming water line and the outgoing line to the hot water in the house is also 3/4 and I want to put in a Titan Tankless N-120 with a filter, two ball valves, and a pressure relief valve. I wanted to know the perfect and best way to install the unit! Almost all filters I see are 3/4 so would you first put the filter on the 3/4 line, then put a reducer to go from 3/4 to 1/2?? Which reducer is used and is it just soldered in the pipe? I would like to see some examples. Ok after the filter on the cold side would I use 1/2 inch for the pressure relief and the ball valve after the reducer or would I go with 3/4 on those and then put the reducer?? Again come someone could show me examples online it would be great. Would that be soldered on the pipe as well? The reason I ask is they have a million of these kind of parts and I don't want to get the wrong one. Some are threaded, brass, non lead, so I am confused. On the hot water side of the Titan would I put 36 of copper pipe at 1/2 inch and the put and then connect that to the 3/4 line to the house? What do you use for that? Another reducer type thing? Again can someone show me the part? Also if I put another ball valve on the hot water side would I just use a 1/2 and put it a few inches from the unit on that line? Anyone that can lead me to the proper parts and best installation method would be much appreciated as I can not afford to hire anyone. Thank you to anyone that can guide me in the right direction as I want to do this project myself. Come right out of the units unions ( Which are 1/2 from your last post if I remember ) and use 3/4 x 1/2 male adapter. Then you pipe all 3/4 from there. Cold line 3/4-- valve--filter-- valve--then to unit hot line from unit 3/4--tee with relief valve 3/4-- expansion tank with 3/4 tee-- Then to fixtures. Page 18 here. Ignore all other stuff. http://www.noritz.com/u/manuals/inst...l_nr111_sv.pdf Fired up, you scaring me......Not sure if I should offer advice here. I think the electricians have stated you may have an issue with 80 amp unit on a 200 amp panel. Have you even taken a permit out and checked with your POCO as other suggested? It seems dangerous to me. I would feel bad if your house caught fire from electrical issues, and I am guiding you on the plumbing end. But it seems your determined and will end up hooking it up anyway. Sorry but I always want people and thier homes to be safe, and I feel you should follow all codes and regulations regarding this install. Mike NJ
