adding a second breaker for upgrade to a tankless water heater

hello all, I am upgrading my water heater to a tankless since mine went out yesterday, it requires two 50 amp separate breakers. I currently have a 30 amp already installed for the old one. I figure I could just replace the 30 with the 50 and that's one, how would I run the wire through the wall to the breaker box the way the first one is as the house was built? if someone has a link that would be great also as I haven't been able to find a decent one to go by.

Thanks all,
jeff6146

You need to pull two new cables. The old cable.Is not large enough for 50 amps.

Before you install that water heater you need to see if your existing service can handle the increased load. You may need a larger.service at considerable expense.
