Why not use an insulated duct.

Well they are in place now ? they are about 30cm below ground and probably OK to not even insulated them.. But just wanted to give it a Spray, I was talking to a lad at a plastics manufacturer and he said the polyurethane pipes are unlikely to react with most things.... Pvc would be a different story
