I have a kitchen and 2 bathrooms. Would going from a hot water tank to
"tankless" hot water in each spot be any kind of a good deal? Seems to me
like it wouldn't be good.

You are pressed on space, the tankless is the way to go. Otherwise I
prefer the water heater tank.

Stick with the tank. Also, I put in a point of use 10gallon electric next
to the front load washer, cause it's 50 or 60 plumbing feet from the
ho****er. They use so little water, the hot didn't have time to get there.
So i plumbed my hot line into the ten gallon unit next to the washer and it
has instant 140 + degree water. costs next to nothing to run.

if you heat with electric just forget it.

you will need 200 amps just for heating water, and more if you
installed 2 units........

electrical upgrade so expensive its unreal, 5 grand estimate

For electric I dought it, if 2 baths are used at the same time it will
take the expensive Ng tankless, one unit. here that can cost you alot
in retrofit.

You could put a small tank less booster for hot water.Frankly, If I
build a new home it will be a tank less system, zoned and piped for
the gas....

Don't try to retrofit now.

We just replaced a direct vent tank with a tankless. I did it because
replacement direct vents run an unbelievable $1500 with labor and a 6 year
guarantee tank. The tankless should last 15 years at least. It cost $3k.

I had it done by gas company expecting a perfect job. It was perfect....
the second time they did it after I bitched.

Tons of things can go wrong. Gas pipes have to be big enuf. So does meter.
Then the plastic pipes they used had smaller internal diameter than CPVC I
had before. They replaced with copper the second time. Then the exhaust
should be slanted down unless they is a condensation collector. Mine was
pitched up the first time.

After it was reinstalled correctly, I can say it is decent but not as good
as a tank. It is slightly slower. Also my basement is much cooler now in
the winter (an advantage in the summer) but cold water is now much colder
and that makes hot water seem to take a long time to flow.

Overall stick with a tank.

For some reason, there is a myth that the "tank" systems are horribly
inefficient and wasteful and that the "instant tankless" systems are
green and more economical in the long run.

For most tankless installations, by the time you get through paying
and solving all the problems, the payback period is going to be a long
way off in the distant future.

Last time I thought about my gas heater tank (I think that it's a
great thing that I don't have to think about it much), the pilot light
has never had to be relit in 10 years. It's like the eternal flame!

In the United States, the "tank" systems are a tried-and-tested
commodity item (in most cases) and can usually be replaced in the same
day at low cost. They last for years and the lifetime can be usuallly
be extended if you take care to flush it and replace the electrode at
periodic intervals.

Yep. Inevitably every couple of months someone discovers this incredible new hot
water heating system that's going to save them thousands of dollars a year and
thinks it's the solution to world hunger.

People don't look at the total cost of a system, only their monthly out of
pocket expenses. That's why leasing vehicles is so popular.

A former AOSmith engineer wrote a great whitepaper on tankless heaters. There
are a few circumstances where it makes sense to use them, but in most
residential applications a standard storage heater is the best solution.
