I recently purchased a Takagi TK1S, I am preparing to have this
installed soon. My question is this: my existing tank (located in my
basement) has 3" exhaust that goes into the chiminey stack, can the
new venting replace this? Does the venting only need to enter the
stack or does it need to be piped all the way to the roof? I hope
this makes sense. I have a couple photos if that will help,
unfortunately I cannot post them here, so I will email if needed.
Thank you.

If it is anything like my installation you are going to need the big vent
all the way to the top. Tankless water heaters crank out a lot of BTU's so
they need a large pipe to vent them. Look at the installation instructions
that came with your unit for the proper size of the vent.

you need LARGE input gas line probably starting at meter and large
vent pipe.

Sadly you will save little energy, no money once you upgrade everthing
so the tankless works./

If your tankless requires a pwer cord, no power cold shower.

with a tank type heater theres still some hot water for a bath or
shower or two

why did you buy a tankless?

I converted from an electric. I was told that they used less energy, but
since I didn't have a gas tank I had nothing to compare. I do really like
the fact that I don't ever run out of hot water, but the maintenance is a
pain. It is also annoying when you are in the shower and someone else uses
water.

Let us know how the installation went/ how things are working.

I'm considering an installtion on a major renovatin. How did you
decide on a Takagi vs. Bosch, etc?

Good luck!

I installed Bosch a few months ago and I just tied into the existing vent
stack with a wye. I'm still using the old water heater for baseboard heat in
my basement and first floor office. Just make sure the pipe is proper sized
and not reduced from heater to existing stack.

Good luck, Rich

I recently installed the Bosch 125 NG tankless heater. This model is
not power vented and can be vented up the chimney. This saved
considerable time and expense.
I was disappointed in the performance of it during the winter when the
incoming cold water here is very cold. I followed some good advice I
got on this ng and used my tank heater to prewarm the water. It is set
on the lowest temperature. The entire system works great.

What area of the US are you located? I live in Pa, and been hearing
not so good things about winter and tankless heaters.

regular gas tanks are 40 gallon 30 thousand BTUs or so.

but high BTU 75,000 BTU 50 and 75 gallon regular tanks are available
and provide wonderful and for us unlimited hot water.

cold incloming water temps near 40 degrees in winter is no problem at
all

remember the energy savings fr a tankless is bogus since during the
winter the lost heat helps warm your home.

unlike tankless regula tanks require nearly no maintence

the energy a tankless saves will likely ever pay back the added cost
of the tankless

This is only true for electric tank heaters inside the thermal
envelope of a house in a heating-only climate zone. Gas tank heaters
lose a lot of heat up the flue when not running--obviously the
flue/tank interface is not insulated.

says...

Backflushing the heat exchanger once a year isn't much maintenance for a
tankless, either. Maybe 20 minutes a year. Hardly something I'd
consider significant in selecting a water heater, but it's the only
regular maintenance my Takagi requires.
