Tankless Water Heater on 150 amp House?

So I'm doing a rush rush rush job at reasearching whether or not to do a tankless or a tanked water heater... (garage flooded this morning).

I'm looking at purchasing a Titan N-180 Tankless water heater which calls for (I guess) two 220 lines for a maximum of 77amps.

specs from titantankless.com: N-180 * 18KW * 220/240volts * 77amp

Is this going to be okay for my house which only has 150amp service? There's a good change I will run hotwater, dryer, AC and possibly stove at same time... maybe.

Replace the WH and include a Redytemp with the installation which will allow you to have hot water instantly during regular ussage times using the onboard timer and use the push-button on-demand operation during other times. Doing so minimized our hot water waiting no matter what time of day it was.:huh:

Final project

Fun DIY project...

I wanted to use the braided flex for both connections but it just didn't work out on the cold side. The bend would have been too hard.

I had to replace the shut-off valve along with the water heater. Pretty bad when the valve failed as well as the tank... it made the interim time a bit of a pain.
