home depot and lowes sells these, models requiring either 2 x 40 amp or 3 x 40 amp
breakers, depending on power

has anyone installed these and what are your observations / recommendations ?

Nope, not those. The Germans make better ones. I have 2.

If you are using electric water heating, now I wouldn't bother. There is not
really any gain in economy.

Your lights may dim and you could overload your electric service, depending
on how modern your wiring / fuse panel is.

I doubt you will have enough hot water supply to supply a shower and a dish
washer at the same time.
My rinnai gas unit runs 185,000 BTU and it can be "just barely enough"
sometimes.

Learn the BTU math and get educated so they can't sell you the "infinite
supply of hot water" BS. If your water comes form the ground at 45F your BTU
cannot produce as much volume due to a limited BTU rating. Do the math.

There is also (in a gas unit moreso) a delay in reecognizing water demand so
if you trun the tap on and off repeatedly you may never get hot water. This
inputs a cold water shot ("sandwich") in your pipes if you did this in the
shower.

My apologies for the multiple postings.

Apologies to all. Damn NNTP is screwing up and doesn't send confirm code.

Now this will probably not go through or repeat a dozen times...LOL


Somebody nudge Josepi. He's stuck.

Been having the same problem the past few days. I am using teranews as well
but wasn't sure of XNews was part of the issue. Since you are using OE,
XNews is probably not a contributor.

Maybe 1 out of 10 works properly.

If you haven't figured it out, just send and if Waiting... persists then
just Stop it. It has been sent and will show up. It will not show up in
your sent folder (Xnews anyway).

Don't do it. A neighbour converted from electric water heat to a normal
gas fired tank. Her monthly electric bill went down by over three
hundred dollars...and that is at 8.3 cents for a kilowatt hour.

Hers was the 2 X 30A version of an 'instant' on water heater setup.



mike

She must have had a short circuit or something wrong with the unit.

$300 at 8.3 cents would be about 3600 kWh. That's on the order of 12
million BTU, enough to heat almost 15000 gallons of water from 40 degf
to 140 degf.

If she really uses that much hot-water in a month, that's one
loooonnnnggg shower :)

ransley you dont know how many teenagers live there.......

neighbor may have converted to other gas appliances too, like stove
dryer and even furnace.....

My plumber friends say don't expect to save any money with a tankless
heater, long term.

any portion of your plumbing system is susceptible to catastrophic

And it ain't just household plumbing that will
eventually fail...

I hope to get my solar hot water up soon and have a tankless electric
that I'll put in after the solar tank. That would seem to be the best
use, to add a little extra heat when I've had some cloudy days.
Otherwise it would seem like a waste of money, although mine was given
to me. Heat losses from tanks can be minimized. No gas here or I'd go
back to a gas tank as natural gas is cheap these days. They gouged me a
few years back and I turned it off. Not an uncommon feeling!

Just replace the anode rod every few years.
