Power Vent Water Heater


I am wanting to change out my old water heater and replace it with a new Power vent water heater. I just have one question is it good to run a 14/2 wire with a 15amp breaker with a GFCI or is better to run a 12/2 wire with a 20amp breaker with a GFCI. Thanks in advance for any help or input.

Will you be able to make hot water when the power is off?

In general I like to run 12/2 so you have it if you ever need it.
My water heater is only 2a (iirc) so it doesn't matter what breaker you used with it.

Why do you want a GFCI? Mine isn't, and unless there is a new code requirement I don't know about, I would say it is highly undesirable.

I would ask how the unit is wired and the location of the unit before saying it is undesirable. If it is a cord and plug unit and located in a unfinished basement, then it would be VERY desirable.

Why? Doesn't seem particularly dangerous (especially since no one ever touches a water heater) and I'd rather not have my water heater go off because of a flakey GFCI.

GFCI's are not flakey, and its code for a reason. If you dont understand the code then I suggest not answering in a manner that bypasses important code requirements.

If the receptacle is in an unfinished basement it would require GFI protection.

I specifically said unless it was a new code requirement, and someone pointed out it was new in 2008.

And sure, they are flakey.
I can go a year without touching my waterheater, and floor lamp that I touch several times a day has a much higher potential for being dangerous on a ground fault then a water heater. So it is rather hard to see them as dangerous.

If you don't know how to read then I suggest not answering in any manner.

I would hard say GFI's are flakey. They have proven to be reliable for many years.

Isn't the copper piping connected to the water heater,also connected to grounds and neutrals,which in turn is connected to the floor lamp that is touched every day?

Prior to the change there were a few exceptions for stuff like alarm panels and equipment plugged into single receptacles and ones in a dedicated space like behind a freezer. Otherwise unfinished basement receptacles have needed GFI protection before 2008.

They certainly can be flaky. Try testing `em after a bad lightning storm has blown through.

We get more bad GFI reports after such events.

Is a gas water heater with power vent considered a water source, requiring a gfi?
