I will go with the thermopex . Thanks everyone for your help

Kinda ironic you said that in the thermopex failure thread. 

If your wanting foam filled, may I ask why you would rather have thermopex than logstor??  The outer shell of logstor is way thicker, the foam is of higher quality, the lines are bigger in diameter!? 

Just wondering?

The thermopex is getting worse as winter is progressing...

Check this out where it passes under the road, keep in mind it's doing this other places as well.

 People pay a lot of money for heated driveways.

The only bend I will have is coming up at the back of the pad and down the side of the pad, I will manually slide the 90's over it so I'm not having to pull it through them, I'll just slide the 10' sticks over the pipe from there onto the house

Having had a system with a lot of heat loss with uninsulated lines,
I am paranoid.  I bought z-supply line, ran it inside of 6" pvc pipe.
I used 45's everywhere and had no problem at all pulling it through.
I ran it about 45 feet.
I am having very liitle heat loss, or so I believe, since I seem to be burning a lot less wood

Then 6" of closed cell foam?

Not sure what you was referring to but sounds like he simply pulled the entire wrapped line package through a 6" tile.  To me that's probably the ultimate way of doing this

If you are referring to my post. No.

I bought z-supply 4 line insulated pex.  Then I taped thermostat and electric wire to the outside of the ribbed tile and then i pulled  with a rope  and the brother -in -law guided it into 6" sewer and drain pipe. Was not hard at all.  My thoughts were if I ever have a problem I can pull it all back out without digging up the yard.


And it does real well...

That's supposed to be one of my summer projects, to buy new 5 wrap and pull the entire thing through a 6" PVC tile, hopefully I get to it

Z-supply doesn't make 4 line insulated pex.

They did until last summer, he said he was quitting because it was too hard to work with. I bought part of his last roll.
I was kind of hoping he would change his mind because I think my brother in law and son in law both should switch to it.

Heres mine - Hmmmm

Pic taken 3/18 in Northern IL
Had just rained for couple days with warmer weather and then turned cold and light snow.
I freaked out, ran tape in pipe end to end, found Zero water.
Gauges show 3deg loss in round trip with no load - 250' round trip

Installed in Oct last year.
Badger 3 wrap in 4" Black corregated pipe as supplied
2' buried with about 1' sand above and below pipe for protection from rocks and then covered with dirt / gravel.
No snow melt all year except a small amount near unit where all there lines come into Furnace on warmer days and small amount where it enters house 4" below grade.

Interesting that it did this only on rare occasion. Not sure i oculd ahve done any better on the install except the PVC and maybe 5wrap.
Wonder how much Im actually losing to the ground or is this a freak thoing based on weather / ground moisture since the pipe is dry.

Wet soil wicks away heat much faster, thats likely why you seen it after the rain.  They all seem to do this a bit when the ground is near freezing or extremely wet.
