revisited-tankless heater<BR><BR></FONT></DIV>
<DIV><FONT size=+0><FONT face=verdana,sans-serif>All, Our Bosch propane
tankless heater is beginning to fail and we are thinking about replacing it
with another tankless. It is located in a shed next to a cabin that is
not always used, although for the next several years we anticipate a regular
single occupant. The current model has a pilot light; obviously we
prefer one that is electronically ignited which I think they all are
now. Suggestions, thoughts? I've read a number of reviews.
It would not be too difficult to install a passive solar heated system in this
cabin too, an alternative.<BR><SPAN class=296243622-20022012><FONT face=Arial

class=296243622-20022012><FONT face=Arial color=#0000ff size=2>I think all gas
heaters are electric start. I haven't seen a pilot light for years. No
comment on the solar but you are likely to need a booster anyway, and the new
gas heater will suffice for that.</FONT></SPAN></FONT></FONT></DIV><FONT

<DIV><BR>I've used tankless for years now but one aspect of the type I dislike
is the fact a lot of water goes down the drain before the hot water finally
reaches the faucet. In this cabin the shower is within 10 feet, with the
sinks not over 15'-18', but water loss nonetheless is a negative
factor.<BR><BR><SPAN class=296243622-20022012><FONT face=Arial color=#0000ff

more often a solution than the problem, which is more likely to be
down to bad architecture, There is even a possibility that the pipes are too
big, and you might check the insulation while you are at it. My daughter has a
cold water diverter in the hot pipe to a bathroom. It was pretty expensive and
I think it's only for the desperate. </FONT></SPAN></DIV>
