I'm putting a thermostat on my landlord's solar hot water heater. It has
about one foot of exposed copper pipe at the top of the unit. I'd like to
put the sensor there. It sits out in the south Florida sun and salt air.

What insulating material would hold up to this environment?

Foamed glass, but it's a bit archaic. The air conditioning guys down
that way should have an idea of plastics that hold up, if any do.
Fiberglass works if you can keep it dry, but that's a big if there.

How about "Great Stuff"?

The black foam that HVAC tubing uses, should work. For a
while.

Do you mean the insulation on the sensor's lead wires? Teflon has good
UV resistance.

I thought you were joking. It looks like just the thing to use.

Thanks

i'd think great stuff is very vulnerable to UV (i've seen it here turn brown
and erode as a result of what i assume is UV attack). i'm wondering about
putting a covering of aluminum foil scrunched over it, tie it on with
stainless safety wire?

b.w.

That should work. I used to live in Tucson and we used heavy duty Al foil
to cover all kinds of stuff to keep the UV off. Plastic pipes & wire were
just wrapped and no additional securing wires were needed. Then again
we never had hurricanes to deal with. Beware of the woodpeckers. If
it sounds hollow they'll peck it to pieces looking for bugs.

My reputation is THAT bad, eh?

(side note)

My new .38 cast 148 gr. wadcutter with 3.0 gr. of 700X are making one raged
hole at 25'. That's the best of six loads I tried. The same load works as
well in my S&W 442 as it does in my S&W Model 19 and no leading in either.
I can cast 36 pieces per minute easily and tumble-lubed with diluted liquid
Alox. I think I have the "magic" load for this powder and bullet. How's
the .308 and the Dillon? I have a bunch of 124 gr. 9mm Truncated Cone
bullets cast if you want to try some.

My reputation is THAT bad, eh?

Its worse.

That would be a big Roger on the 9mm bullets. "The Kid" and I have found a
great new hobby to spend together - loadin' one evening then shootin' the
next day. Just a couple months ago, I thought 1000 rounds was a lot of ammo.
Guess I'm wrong.

The standard thing done in industry is to use pre-formed fibreglass have
pipes ,which are held together by wrapping with duct tape. The entire lagged
pipe is then covered with Colourbond steel sheet metal, rolled into a shape
that can be slipped over the insulation. The linear joint is held together
with pop rivets or self tapping screws.

Cool! This is the bullet:
http://www.midwayusa.com/viewProduct...tNumber=340779

E-mail your ship-to address and I will send you some. They will be lubed
with the diluted liquid Alox. It's hardly noticeable and looks like a
varnish but it seems to work well at less than hot loads. They cycle in my
XD-9 just fine. What pistol powder are you using? I fell into 16# of IMR
700X, so that's my pistol powder for a while, a bit slower than Bullseye.

You can get black spray foam which is supposed to be more UV durable.
The pond folks seem to use a lot of it. Or you put on enough of the tan
stuff that what turns dark brown serves the same purpose. Nothing much
is permanent.
