Default Hot Water Heater

I need to move an electric water heater about 10 feet into another room. I need to extend the existing wire cables to the new location. What would be the best way to splice the needed additional cable length to the existing cable?

Using the box currently installed in the wall for the water heater, extend a 10-2 from there. Splice the #10's with appropriate sized wire nuts. Your box must be 12.5 cubic inches or more.

At one time water heaters if not in sight of service panel, needed a disconnect(D/P) at heaters location. If still in code may want to keep in mind if locating out of sight.
See if someone verifies this??? Out of date here.

Still does. Either need a disconnect, a breaker in sight of the heater, or a breaker lock out device.

The panel currently at the water heat is the service panel/disconnect. If understand correctly I will need to move the service panel to the new location, and add another box in the wall that is 12.5 cubic inches to house the splice. Also, the splice can be done with typical electrical nuts that are the corrrect size?

If by Service panel, you mean for the whole house, no that doesn't have to move unless there are other reasons forcing the move. If that box is a disconnect only for the heater, then I'd move it to the new location.

The splice box doesn't need to be added unless there is no box there now, or the one there is too small. 12.5 cubic inches is the minimum. I'd go larger if you can.

If you install a box by the new heater so you can run a flex metal conduit whip to the heater then it would also need to be 12.5 cu in or larger. You could also run the 10-2 cable to a 30A airconditioning disconnect at the new heater location. Then connect the water heater to that.

I can't tell exactly what you have and what you are moving by your terms. If you are using accurate terms, I would not move a service panel (a panel with a bunch of circuit breakers) when I just wanted to move a water heater. Is it easier to originate the new wire to the water heater from this panel, or from its old wall box location?

with out seeing? if your present electrical conn to your water heater is junctioned in a Junc box at the heater, poss on ceiling joist with a piece of conduit run down to the heater.(could be numerous ways)(whats there now?)
If j box on ceiling, then just extend circuit 10/2wground or conduit and #10 wires to new location. You could add a 30amp rated, 2 pole toggle sw as your disconnnect. Existing breaker in main panel would still remain as O/C Device.

There is a disconnect box mounted on the bathroom wall next to the water heater. I assumed this would get moved with the water heater. I think, I would need to put some kind of box inside the wall that would contain the spliced wires? This is the part I am not sure of.... What is the best way to join the wire that is needed to run from the old water heater location to the new location. I needs to be put inside the wall...

Use an "old work" device box. Put the old and new wires through two knockouts in the box and then push it into the wall. These have little ears you screw out behind the sheetrock to hold the box in place. Put a blank cover over it when you're done splicing.

The junction box is extremely easy to install and really is helpful for safely connecting wires. I just installed one for another project (recessed lighting) and I was very happy with using it with the covered plate. I think there are some great comments, but I would take the first post seriously, because you are going to have to extend the wires. If I was you, I would replicate the exact set-up by simply moving the wires, which should keep you within code. Good luck!
