That link pulled up generators. I have a Bosch 117000 btu battery
ignition. It is great and has a 4 yr payback over electric tank for me.
If you run the water to slowly it may not come on but other than that it
is fine. For several uses or a family look at a 180000 btu unit, look
at Rinnai, and Takagi with remote thermostats. You need alot of gas and
may need to resize the gas line inside, plan it out before you buy.
Energy saving depend on use, for a single family or infrequent use it
will be greatest , perhaps 25%, for a family maybe 15%. There are units
by Takagi and Rinnai that have much higher efficiencies than regular
tanks, cost is high but gas is also up so payback and savings are much
greater now. I replaced a highly insulated electric tank and verifyibly
have a 4 yr payback on a 700$-US unit, Chgo area rates, im very happy.
Also no sediment builds up so efficiency does not go down as gas tanks
do. Apx 1/3 of your gas bill can be HW, tanlkess do make a large impact.
and are largely missunderstood and overlooked.
JM You state, "the jury is not stll out". You may not be convinced,
but myself and 99% of others I have read see the savings. As an example
my summer gas bill is 5-6 therm now with cooking all food on gas and 1-2
loads in a gas dryer each week . Yes I transfered from electric tank,
but my electric bill dropped 30$ a month with a 5 yr old Rheem with foam
insulation and fiberglass blanket . The electric was set to its lowest
setting, apx 105f, if it was set 20-30f higher as many do my verified
savings would have been much greater. I save apx 200 a year as I figure
it, at that savings I can afford a repair when it occurs.
Without a tank to rot out in 10-15 years, or build sediment and
reduce efficiency the tankless life of 20-30 years becomes an even more
atractive option . I just pulled out an 18 year old tank at a different
location on Chicago water it had apx 12" -14" of rock hard sediment in
it, that heater was probably running at 50% efficiency, where that won`t
happen on tankless, how much efficiency robbing sediment is in your
Ahhh mr. Meehan. why do you insist on giving answers to things you
know nothing about? I have worked on quite a few of these and they are
not that much more complex. they are noisy though as they need a power

You must be talking about tankles water heaters, something i have no
experience with. Tankles water heaters apparently need something
called a power vent. Perhaps having something to do with the
atmospheric pressure on alternate planets?
Just a quick not to the OP, I did notice, one time when i took a bunch
of drugs, that the whoosh of the gas burner on my tankless water
heater was louder than the whoosh on a tanked water heater. Different
colours to the sound too. Suprisingly, the next day there was no
evident difference in sound or colour. Go figure.
They must suck since most of Europe and EastAsia use them, and you
know how backward those people are. I have one hanging off the
exterior wall of my house and aside from providing steady instant hot
water it is of no use. I often wonder how i will fare in the event of
the Apocalypse without 50 gallons of hotwater stored in my basement.
Fortunately I have many pet bottles filled with water surrounding my
garden to keep cats from peeing on the flowers.
