best ways to pipe hot water between two buildings?

Hi,

Looking for ideas on what piping to use to pipe between two buildings. Based on the distance of the run (about 150'), I've been recommended 1 1/4" pex wrapped in the foam insulation, and this is going to run $14 a foot.
Any other options, for piping or for dealers who sell this stuff?

Thanks.

Make sure it's Pex-al-Pex not "regular" Pex. They should be seperatly insulated. On a short run it might be OK to run them together and insulate, but on a run as long as yours you'll be making a long narrow heat exchanger if they are not seperated. By the time the hot water got there it would be cooled by the return line if they ran together.

If you find any pex-al-pex in 1 1/4 please post the source or send me a pm.
