Hey all,  I have a question about my shop set up and the amount of elbows I want to use.  I have a hanging heating unit in my shop and my stove is about 20-25 ft. from my shop and about 80 ft. from my house.  My water lines come into my shop(just above the floor) and run about 40 ft. to my heating unit(along the walls).  I would like to run them along the wall a little more "neater" for lack of better words.  This would require me to install 4 elbows in the lines to tuck them in tight to the walls.  Is this going to be ok?  If not what is the better way or what do I have to do to use these elbows?  thanks all.

metal or pex ..I guess metal ...if u insulate the chit out of it ...it will put more heat where u want it  ...the 90's will slow it down  we will need all distance /pipe dia/and pump info

On a run that short, a few more elbows shouldn't make that much difference. You need to be careful to allow for the expansion of the pex though. If it is cold when you connect it, it may push out away from the wall when it gets hot. If the pex is hot then you install the elbows and you put tight against the wall, the pex could retract and possibly pull apart or do some other damage.

This is plastic pex pipe and metal elbows.  I thought I could build some kind of insulated soffit cavity along the wall and run my lines inside that.  Thanks.

If it were me, I would use a good quality pex such as Fosta pex by Vega or pex al pex, it has an aluminum barrier that does not allow the pipe to expand or contract and is rigid enough that the 90 could be done pretty tight using a pipe bender without the 90s, typically pex can expand as much as 18 inches for every 100 feet, this can make a pretty sloppy install!

So I take it the metal elbows are real short?

A few options is to get a long radius elbow and use copper inside, or sweat a barb into each end of the long radius ninety.
