Can black ABS plastic pipe be used to pipe between a wood and oil boiler? My two boilers are about 25ft apart and require about 60ft of piping. To save a little money, I'm piecing together the run using black iron pipe which is about 50-60% cheaper than copper but I will have to run to Home Depot about 10-15 times to make the various cuts and threads on the pipe. Black ABS pipe could be extremely easy to assemble and is around the same price as black iron pipe.

Please let me know. Thanks.
 
Short answer NO. You need O2 barrier pipe, I met a fellow that used black plastic pipe and 2 years later he needed a new boiler.
 
I think the heat limit for ABS is about 180F, I wouldn't risk it
 
Where do you guys source 1-1/4" PEX tubing? My local home depot and lowes only sell 1-1/4" SIL-O-FLEX which I believe isn't rated for hot water. All the hot water PEX tubing is only sold up to 1" diameter.
 
Try Ebay, or you can double up the runs with smaller pex just figure your x-sectional area's. I was going to run 2 -1" pex instead of 1.25 pex then I got a good deal on black iron pipe and fittings. If i had to do it over I would do pex. Watch out on heat ratings and 02 barrier, some pex is not a barrier pipe and I have heard of some pex letting go on high heat situations.

Gotta be careful here, two pipes with the same cross-sectional as one larger pipe do not have the same resistance.

Check this table:

http://www.alliedpex.com/LITERATURES/PEX_Pressure_Drop_Table.pdf

1.5" pipe at 16 gpm is 0.025 psi per foot pressure drop, whereas two 1" pipes at 8 gpm is 0.041 psi per foot pressure drop, a factor of 1.64 higher.

I received a 100' roll of PEX tubing last night. How do you unravel it??? It was very frustrating trying to unwind the roll by myself. I let the roll sit in the 85 degree boiler room over night and I have a helper coming over later so hopefully it's a little more plyable. I'm also thinking about capping one end and filling it with 180 degree boiler water.
 
Grab the outside end and secure it, then roll it out. Do not pull the inner end out horizontally or you will have troubles. It definately helps to have an extra hand.

Or one can guy can grab the outer end and pull it while the other guy picks up the roll and rotates it. Its very awkward to work with it has a good memory.
 
I have an uncoiler, works great.

the warmer the better. For wintertime installation I would warm it in front of the LP salamander heater for a few minutes.

Large diameter pex is easy to un-roll only when the weather warms to 80F or so.
