I did a quick search but didn't see anythign so I figure I'll ask.
I have aprox. 35 ft runs of 2" PVC that go from the spa to the equipment. My pipes are only maybe a foot or so underground which is above the frost line in WI. I've got one 3" suction line and two 2" return lines. That's quite a bit of surface area exposed to the frozen ground. I think this may end up being a signifigant area for heat loss in the winter. Escpecially when Ill probably be running the pump on low almost constantly to protect the equip. from freezing.
So, the question is... Do I need to insulate these pipes? If I do, what kind should I use?
The plan is to use Reflectix wrapped around the pipes. Mainly because I heat it's good at reflecting heat, it's not bulky, and it's waterproof. The thing is, I'm not sure if this will be enough.
Link to their site. I'd be using the normal Insuation(4'x50' roll)
