Thanks for the reply. Not sure where I got the impression that PEX 3/4 inch
could be coiled into a loup of 7 inches...Like I said, I never worked with PEX
before and with new technology coming out every day, maybe they have a braded
PEX or some product that can be?

PEX is flexible but only to an arc of maybe 3 feet diameter. In your
situation you might consider a loop or an arc allowing you the extra length
when/if you need it. With a hundred feet though you should be able to replace
it when that occasion arises.

I have never worked with PEX before. Under the impression that PEX was
flexable, I thought I had an application here where PEX would be ideal. Last
year I added a hot water coil to my wood/coal furnace to heat my domestic hot
water. This setup consisted of a stainless steel loup, approximately 24 inches
long and installed into the fire box of my furnace. Being approximately 20 feet
away from my electric water heater I could not utilize a thermo-syphon, so
installed a small circulating pump to move the water from the bottom of the
electric water heater through the loup installed in the wood furnace back to
the top of the electric water heater. I used 3/4 inch soft copper to make the
run from the electric water heater to the wood furnace and back. This setup
worked great last winter, reducing my electric bill considerably.
This summer, my electric water heater had to be replaced and like always, the
inlet, outlet, drain valve, as well as the pop valve are never in the same
location on the new tank as it was on the old. Not wanting to plumb the system
again with copper (knowing a few years down the road) I will have to do it all
over again, I thought I would connect PEX from the copper I have in place
overhead in the floor joyste to the electric water heater, thinking that PEX
would be more flexable and when the next time I have to replace a water heater,
the hook-up would be easier. I bought the crimping tool, copper crimp rings,
the fittings I needed and 100 feet of 3/4 inch PEX tubing. From examining this
PEX tubing I know that it is not as flexable as even soft copper of the same
size.
All that having been said... Did I purchase the wrong type PEX? Without
installing elbows / 90 degree fittings, is there a way to accomplish a
substancial bend in this type PEX (perhaps type C). perhaps using a heat gun?
Or would heating the PEX enough to accomplish my goal diminish the integrity of
the PEX tubing?
Thanks :)
