Title: Insulation for 1 inch copper
Post by: DBeleskey on April 04, 2019, 02:59:24 PM

I am running the copper lines in the basement and wondering what is recommended to insulate the one inch copper lines inside the house ? I see the foam based stuff available at Home Depot but not sure whether it would tolerate the high temperatures or not ? I have also seen fiberglass stuff but it seems really expensive..
Any recommendations ?

I just use the foam stuff and metal tape to make it look a little better.

The foam stuff works fine, personally I prefer the rubberized stuff like is on refrigerant linesets. Menards carries it, not sure about HD

That rubberized stuff from Menards melts to the pipe. I prefer the regular foam stuff.

I personally don’t worry about it unless its in an un insulated crawl space. Any heat that radiates of the pipe into the living space isn’t really lost heat anyways.

Any pipe that circulates continuously I insulate to keep from sending excess heat into the house on warm days, a line that only circulates on a call for heat I don't worry about as much.
I burn all summer so I think about "temp creep" in the house more than some.

Thanks everyone for the input. I will wait and see if I really need it before putting it on. But good to know the foam stuff is okay to use if I do need some. I was just thinking about putting it on the pipe where it goes to the first exchanger, the plate for DHW, but maybe don't need it. The pipes are in a heated basement in a furnace room and I really kind of like the look of the copper. I hope to get it done in the next day or two, if I don't get called out. Will post a picture when done..
