Title: Outside insulation
Post by: Bluegrass Wood Burner on January 10, 2016, 08:33:41 AM
This is my first post. Been reading your posts for year or so and have really gained a wealth of knowledge. My question is what type of insulation do you use to wrap from the ground up to the boiler. I know that the swimming pool noodles are good as well as the plumbers version of that type. What im looking for is wrapping all the pipes with something that would keep the cold wing from penetrating to the pump, pex pipe. Thanks for opportunity to join. :thumbup:

What I did was use regular pipe insulation around the 4 lines. Then I took 6 inch drain tile and cut it in half the long way. I cut that into to pieces. Wrapped the first piece around the lines and then put the second piece around the lines with the cut on the opposite side if that makes any sense. The pipes don't fit inside the 6 inch drain tile which leaves the drain tile open an inch or two on the cut side. That is the purpose of the other drain tile is to wrap that exposed section.

What honda said.

Or if you want it water right do something similar then wrap some of that self sticking butyl rubber around it as well.

What kind of pipe is it?

My lines come up into an insulated compartment on my heatmor.  Once the Logstor penetrates the concrete pad, the insulation is stripped off and connected to the boiler.  Everything in that compartment is insulated from the outside elements.

Same here, but sometimes you have to work with what you have.

It's 1"pex. I have it wrapped in the plumbers type rubber 4 ft. sections cut to length and zip tied. I then wrapped it all in regular house insulation but it's rotten and looks bad and not really doing the job I want. There is a silver colored wrap I have seen and wandered if anyone has had any experience using it. I like the idea of cutting drain pipe in sections. Any other ideas would be considered

What brand was it to start with or was it home made?


If home made you might be loosing a lot of heat to the ground, more so than whats exposed between the ground and the stove.

I used the silver wrap on my install 2 years ago. I wraped each pipe from my logstor to the boiler than I wraped them again joining the two pipes in one if possible. I bought it from Lowes and it was made with denim and easy to install and seems to work great and hold up well. I taped the seams with aluminum tape used on ducts.

The pipe from about a foot above ground down is in the original insulation filled drain pipe. When it was installed we put sections of pipe insulation down in it as far as we could up to where it goes in the boiler. It's not a homemade, it's a Ozzark Biomass from Dobbs brothers. Just wanted to wrap all those pipes up together in something

That's the product I was wandering about UP Doug. Does it come in a roll? Is it durable in wet weather and outside conditions. I'm hoping not to have to re wrap these pipes every year. Just installed a year ago and already looking kinda ratty

Yes, it comes in a roll, found it at Lowes here. They have fiberglass and denim types, I used the denim and was very happy with it seems to be holding up very well, going on three years here. I did tape the seams where needed with the aluminum tape. Happy with mine, it looks good.

I'm not sure the distance you're talking about insulating but I wanted to better insulate my lines from the ground to the bottom of my boiler. I took the foundation wrap (grey fiberglass type coil stock) you use to cover foam insulation on the outside of a homes foundation making a tube about 9 to 10 inches in diameter coiling it around my existing lines and drilled some holes to be able to zip tie it together. I then sprayed in minimal expanding great stuff foam insulation to fill the bigger outer tube. Let it set for 2 days and cut off any extra foam that oozed out. Won't ever have to redo it but may be a booger to get off when I have to. Attached a photo hopefully, may need to blow it up to see it.

I really like the way that looks. It's only about 4 feet total from top of ground up to where it goes in to boiler.
