Insulating Monoflo Pipe
I tried posting this on the plumbing forum but didn't get any response so I figured I'd try here. I have a oil heat with a monoflo system that circulates water around the basement of my home and feeds convectors on the 1st and 2nd floor. I would like to insulate the pipe and was curious whether there is a particular insulation that I should use for this, or would any pipe insulation work? The pipe is 1" in diameter and obviously gets pretty hot. It looks like the original owner had used the aircell asbestos insulation around this pipe in parts of the house, but that's now gone. Any thoughts??
