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.

  • 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.
