Just saw your post. I had a similar situation (kinda -- plumber wanted
to charge me $1500 for tankless water heater, which seemed too much).
I found a website called www.Houseneeds.com and not only did they give
me a good deal ($855 for the same heater) but good advice, too.
Hope that helps.
If a guy was going to charge you $1500, why didn't you jump on it??!!! I'm
not questioning your ability on installing one
yourself, but don't you think it's worth paying someone to do it?
What happens if you have a problem with it (while installing or 6 months
down the road)? Are you going to fix it? Can you fix it? Will the
manufacturer honor any warranty parts if YOU install it? Will they just send
you a new part if YOU say it's bad (as opposed to someone
diagnosing that the part is actually bad)?
I just think to pay someone, what, $600.00 (if you do in fact get one for
$855 and that includes all of the required accessories
and parts needed for installation) and then if you have any problems within
the warranty period, you call THEM and have them
make it right.
