Do any of these manufacturers that make a wrapped product offer it without the tile? I just need the insulated line, not the cover for use in the shop. When I visited Natures Comfort in Shipshewana they offered it, but only in one inch pex, not in pex-al-pex or 1 1/4. I might get away with their smaller stuff on my water to air heat exchangers, but I think I should have the larger line set for my plate HX.

Far as the water to air heat exchangers in the shop, more than a few people suggest placing them low as possible to the floor while my original ideal was to mount them in the rafters and let the fans pull warm air off the ceiling. Any real advantage to mounting them low? If I move a few things around I might be able to get them down low then just install a couple of cheap ceiling fans in the rafters. One advantage, maybe, would be with mounting them low it wouldn't mess with the gas so much with the wire welder, or if it was a problem I could always try to stand and weld with my back to the HX'ers. I've also thought about mounting them right above the shelves on the walls which would be about 7' off the floor then installing some louvers and angling them down.

They don't usually offer it without the tile because it doesn't save much after getting it properly protected for shipping.

I can try finding it for you. If you are interested, send me a PM.

I think one reason people try to keep the water to air exchangers low, is that if they are above the top of on open system boiler, you will have problems with air entrapment and not being able to purge lines of air

Even with an Autovent at the highest point of the lines?

...an autovent above the top of your open boiler is a bad idea  , besides the fact that I think that autovents only work in pressurized systems.  Also you would not be able to keep water in the pipe that fed the heat excahnger because everytime the pump was off and an air bubble hit the auto vent, the vent would open and all the water level would normalize, and drop back into the OWB.

I'll have to ask the guy in town what he did, he has one modine heater in his garage overhead and two in his shop up in the rafters, maybe he just used a bigger higher flow pump to brute force the air out. Not sure he even handles them anymore but he used to be a wood master dealer.

Unless I start cutting cement out, no matter what I do, gonna have lines higher than the boiler water level no matter what.
