When you install an electric tankless water heater, do you have the
electrician hook up the wiring first or do you have the plumber hook up the
supply lines first?

I am thinking the electrical should be hooked up first but not sure.

Thanks,

Mine is gas and everything done by gas company at same time but if I had a
small electric one I would have electician do his job first since it should
be a no brainer as long as you give him specs for the heater.

If possible, you install the most "disruptive" systems first and then work
the other stuff around.

For example, duct work and waste lines go in first. Then other plumbing
"works around" the ducts and pipes. It's "nice" for fixed appliances
including HVAC and water heaters to be connected to duct work and plumbing.
At this point, the wiring can be neatly connected to the appliance. It's
easy to run wires around pipes and ducts but the reverse ain't so each. I

If you have good plans the electrician can wire leaving coils of wire
hanging where he things it should be able to reach wherever the appliance
needs the juice. With the price of copper today, this might not be such a
great idea.

Let the plumber do his job first. The electrician has more flexibility in
locating the wiring. You could have the electrician prewire the unit with a
plug and cord or if it is a really big unit have it prewired with flex. It
could make wiring easier later if the unit is located in a confined space.

First you hang the tank, then whoever shows up first

From a logical standpoint, working with plumbing is more restrictive
than wiring, even using PEX. The nature of piping is that it is always
a compromise with the space available, the fittings that can be
obtained, and access to the input source. Wiring, OTOH, can be run
over, under, around and through obstacles. Some say this is why so
many plumbers have ornery dispositions, a truism I can't verify.

We just had one of these installed. The electrician came out and put
in the wiring first, then the plumber did the pipes, then the
electrician returned after it was plumbed and turned it on.

It's usually easier to route electrical lines than plumbing lines, so
my preferred order is plumbing first. If both are easily routed/
accessible, it doesn't matter as much.

STOP!whole house electric tankless tend to not work well, likely need
200 amps for just heating water if you live in northern area where it
gets cold.

cold winter water temperatures a ery likely disappointment.

In my case it is ok. I am using it only to heat the kitchen dishwasher and
laundry washer in the east wing of the house, the west wing is heater by
another independent tank heater. I am in Miami so the rise I need is not as
high as the northern states. Electric service is ok, it will need 3
independent double pole breakers 240V 3x39 amps. I am getting the Eemax
series 3, with a 5gpm demand I will get 40 degree rise out of 29kw.

Thanks,

MC
