heat pipes in cold crawl space

KRiley

We have baseboard hot water heat. For one zone the pipes run through an unheated crawl space and have lost the ability to maintain heat in the area beyond. Can we insulate those pipes with some product to protect them from the cold and help our heating problem? What type of product do we look for to do this.
thank you

Home Depot or Lowes sells the foam pipe insulation with one side cut so it just slips over the pipe. Comes in 1/2, 3/4, and 1". You would be better off finding out why that area is so cold and fix that issue at the same time.

make sure of the temperature

the insulation is designed for. Some of the home center stuff melts into goo at hydronic temperatures.

Armaflex is a brand I like. It is also available in pre-slit versions. They also make a HT version for solar temperatures. Plumbing and HVAC suppliers generally have the high temperature pipe insulation.
