Burying hot water heating pipe

Member Posts: 14
I have about 12 feet total of copper pipe buried to supply hot water to some fin tube. I'm quite sure some of it has deteriorated as my my wet return did.... would you wrap some copper with insulation? If so, which would you recommend?
Or should I use pex with insualted. It looks like they only sell the insualted pex in 100 foot rolls

Yes you need to use armorflex to cover the pipe .Not as much of a insulation but to protect the pipe from wear of expansion against the cement ....

Hi @Timmmy , Earth can be a tremendous heat sink, and it will probably never be completely dry, so it will steal heat and corrode metal pipe. I'd be tempted to put in a large grey PVC conduit with long sweeps and pull insulated PEX through it to supply your fin tube. That would give you a dry and repairable piping run. Also PEX does come in shorter rolls, or sticks.
Yours, Larry
