A couple questions
« on: April 22, 2011, 10:12:58 PM »
    I finally pulled the trigger and bought 2 year old cb 6048.  We tried to dig up the logstor pipe and some of it was damaged.  I ended up with @ 100 ft piece that I will attempt to use to run to my shop.  It got nicked a couple times with the backhoe bucket.  There is 3 or 4 spots where the outer casing is split or cracked.  I will try to mend them and maybe stuff it thru a 6 inch tile.  Any advice for helping seal this  is welcome.  I am buying new thermopex to run to the house 120ft, but I figured trying to use the old would be worth a shot since I wont have to dig up my yard if it needs to be replaced(just across a gravel driveway).
    Also, I planned on waiting to get everything hooked up since warm weather is supposed to be right around the corner.  After reading recent posts about an empty boiler I have become worried.  The unit is still sitting on my trailer empty.  I still need to pour a pad and dig trenches and all the other happy horse$h1t that is necessary.  How worried should I be and how big of a hurry should I be in?
    OK, last one.  Indoor pex pipe,  I saw some guys use regular blue and red, and saw a guy that used pexalpex and the small amount that I got with the unit has pretty thick walls, I think he said it was pexflex.  Is an O2 barrier recommended?  What is the preferred type of indoor pex?
    Thanks and I am sure I will have many more questions. I love this site!!!

Unless it is some sort of metric pex, it is the exact same dimensions as any other.
Pex is the same outside diameter as the equivalent copper pipe (1" is 1-1/8" OD) and the wall thickness is 1/9th the diameter. The larger the diameter the thicker the wall is.
If what you got is not this size then fittings are going to be hard to find.

I would pressure test the used pipe after the repair and before I put it in the ground. it

If you can afford it I highly recommend thermopex. I have a 1 degree temp lost betwen the boiler and the HX. That could be inportant in the long run when it comes to wood consupmtion.

 Wondering about a spin-down filter kit?  Is it necessary or will a Y-strainer be sufficient?
