Good for 1.5 to 2 baths in moderate climates or 2 to 2.5 baths in warm climates

The N-180 tankless water heater from Titan is capable of producing enough hot water to service homes with up to two baths in moderate climates. If you have a home with 2 baths where the incoming water temperature is about 65 degrees, this is the heater for you. Alternatively if you life further south in warm climates, this heater will produce hot water for 2.5 baths.

The space saving benefits are also undeniable. At 50 gallons, the standard 3 bedroom 2 bath conventional tank heater takes up about 20 cubic feet of space and weighs about 130lbs. The Titan N-180 tankless water heater takes up about .29 cubic feet and weighs only 9.8 pounds making it 80 times smaller than a conventional heater and making delivery, installation and service, a breeze.

Ask a Question
  • Can you replace the heating elements if they ever go out?

    Yes you can but unlike conventional tanks these heating elements are proprietary and very durable very hard for them to go out on you.

  • You say that #8wire will work but #8 is not good for 75 amps

    You're not reading the specs properly. The N180 is wired with 2) 40 amp double pole breakers and 8 gauge wire. Thats a total of 80 amp circuit divided by 2. Hope this clears it up for you. If it was a one (1) line heater it would be wired with 1) 80 amp double pole and 4 gauge THHN wire.

  • Are the fittings 3/4 compression or 3/4 NPT?

    3/4 compression.

  • What's the distance between pipes connections?

    7 inch on center

  • Where does it vent from/what direction

    Its electric no vent required.

  • Do the a.c. disconnect boxes take the place of changing out the breakers at the main box? I have a 40 gallon hotpoint that I need to replace. In general am I going to have to run new wire from main box to power this or will the existing wires for the heater be sufficient. Thank you.

    The existing wires for your current heater will not work. The disconnect(2) are installed right under the heater. But they do not eliminate the breakers. You will need 2- double 40 amp breaker with number 8/2 AWG wire to install this unit properly. To recap you will need 2 electrical circuits rate at 40 amp/ 220VAC each.

  • Does this type of heater can be used in Argentina?. The electricity is 220.

    Absolutely. Yes you may. We sell plenty of these to Argentina.

  • We live in a cold environment, NW Wyoming, on city water. I see warm or moderate climates mentioned. Would this unit work in cold environment for only supplying a single shower bathroom?

  • What is the hottest setting

  • So the unit does not need a neutral? Both black and white go into the same breaker and it just uses the ground to protect it?
