<DIV><FONT face=Arial size=2>Holt and Travis have really hit the nail on the
head re: problems with these types of configurations. However
there is a successful way of doing it. I initially learned many years ago
what NOT to do, and how to provide protection against Flashing of the
liquid. I'd agree, the heat exchanger shoud be exterior. The ones i
built were made with the extruded aluminum used to make thermal solar panels
that allow the friction fit cup to receive a 1/2" copper pipe. A
combination of series or parallel sections would be fixed to the outside of the
firebox. This loop has to be pumped! the pump control should be activated
through a low-voltage relay through a paralleled set of snap-disks (for
redundant safety) located at the heat exchanger. There are a veriety of
fixed/adjustable snap-disks with setpoint ranging in the low to high temperature
ranges. I liked using the fixed 110F on/90F off, they are cheap.

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Assuming you’re
talking about the units that actually installed in the fire box; I’ve actually
disconnected a few over the years because they overheated the water to point
of regularly blowing the pop off valve of the domestic hot water heater.
It’s pretty spooky to rely on the P&T valve in that manner. These
were retired folks that didn’t use much hot water and plenty of time to keep
the wood stove stoked. Hyrdo Coils (etc) would probably work OK for an
installation that didn’t keep the wood stove going 24hrs/day, used plenty of
hot water and had a very attentive owner.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">But to answer Todd’s
question. I haven’t seen a new one for long time. Seems like I’ve
seen a few NOS ones on Ebay and in the dusty corners of wood stove
dealers. There was a product that actually installed on the outside of
the firebox in such a manner that the heat was conducted to it. I don’t
remember who made it and it’s been years since I’ve seen it. Of course
it wouldn’t be near as efficient but that would be a good thing in this case
plus it didn’t void the stoves warranty because you didn’t have to drill any
holes into the stove.<o:p></o:p></SPAN></FONT></P>
