I live in Dallas, TX - if I purchase the hot tub I'm looking at (it requires
a 220 connection), I've been told that I'll probably need a new electrical
service panel - my existing panel is about 25 years old - there are no
remaining breaker slots available on the existing panel, and adding a
sub-panel appears out of the question for some reason - I'm going on what an
electrician told me that I had in to install lines for three external
I'm not anticipating any other electrical major renovation or remodeling
aside from the hot tub.
The existing panel is on the interior wall directly on the other side of the
exterior wall where the electric meter is located.
I know it varies, but what would be a reasonable price range to expect when
I get estimates for this work to be done - assuming I do need a new panel,
and assuming that I still have any money left for the hot tub.
I hope my description of the above electrical stuff makes sense - I'm a
software guy - electricity baffles me - I pay the bill, and I pay someone to
come in and do the work - that's the extent of my expertise..
Aluminum wouldn't matter for a subpanel. Subpanels are still often wired
with aluminum feeders.
I'm thinking more along the lines of the main panel is very small already
(in ampacity and breakers), and trying to put a subpanel with a spa heater
on it would overload the main, or leave very little left.
Ie: a 60A main panel, and then considering adding a 30A 220V spa. That's
half the whole house!
Replacing the panel itself, given no hidden gotchas (liking having to
relocate it) isn't that bad. $200-$500 seems a good estimate depending
on how many circuits to move etc.
Question then becomes do you have to upgrade the service to take advantage?
That could cost anywhere from almost nothing to a _lot_.
We could comment on an itemized estimate, but without seeing it, can't
really tell what's involved beyond the panel replacement itself (and
we don't know how many circuits there are to move, what kind of wire
it is, etc).
Do note that in some unusual circumstances, just _finding_ a big
dual breaker for a very old panel to supply a subpanel might cost more
than a whole new main panel.

It's not just anyone who gets a Starship Cruiser class named after them.
Chicago area. upgrade from 80 amp service to 200 Amp. $1200. $200 of that
was I wouldn't let them trench under a tree and they had to use a "thumper".
Don't forget to upgrade the wire coming from the pole. The previous
homeowner didn't do that and I melted a wire with my stuff cause I thought I
had 100 amp service.
