Opinions on insulating exposed pex in a basement?
« on: December 29, 2013, 04:40:35 PM »

Just curious where others are on this topic involving insulate or don't insulate exposed pex in basement. I insulated mine with some self seal foam wrap and noticed my wood usage went down from it. I can't say I ever noticed warmer floors when it was exposed in the basement so I figured insulating it wont catch all the heat rise.

My basement stayed at 45 to 50 in the winter before I got my boiler and now it's 65 to 70

I have 4 lines of 1" Pex exposed for about 25' in my garage and they are not insulated. When the outside temps are in the teens, my garage stays in the 50's! If I ever install an exchanger in there, I will insulate them in order to be more precise in my heat delivery.

I have my lines in my basement and garage insulated. Before I insulated them, my floors were very warm above them, but it wasn't in a good spot to be warm. The lines run right below my thermostat, and it would radiate through the floors and the hallway where the thermostat was running about 3 degrees above rest of the house. Not a huge difference, but enough to make my kitchen not pleasant on the very cold days. I also insulated the lines in my garage that runs to my garage hanging heater to reduce heat loss. I gained about 2 degrees on my return temps after insulating them. Once again, not a huge difference, but enough that it might help just that little bit.

I insulated mine last year.   I would like to think I noticed a difference in my wood consumption but I really don't know.   I guess it's not really lost heat if it's going into your house.  I just wanted to retain as much heat as I could in the water lines so the air from my vents would be warmer.

Insulate - help push the heat where you want it, I have a small mechanical room (PACKED under a stair well in Garage) before insulation it would get super hot; after insulation still above average but considerably warmer than rest of building.

P.S. In same cramped space is Hot water heater and pressure tank for well, so in winter time "Cold" water is 70F or warmer

For short runs insulation probably won't save any wood, but it will keep you from saying "darn thats hot" should you accidently touch the bare piping.
