Boiler Insulation Where To Buy
While looking at some internal pictures of the new Brewtus III on HB yesterday, i noticed the insulated boiler material.
Where can i obtain a similar ( or recommend a better ) SAFE easy to find insulation, do it yourself material for an Isomac TEA .
Thanks, WS

From the FAQs, see More on boiler insulation. Ian did a particularly neat job:

$151.00 for a 24"X24" sheet?? I'd pay a visit to Lowes & check out the foil backed pipe insulation.

The melamine is inexpensive and easy to work with. Someone commented that the stuff is used in the Mr.Clean Magic eraser.
Here is a thread with Elektra examples.

richard penney LMWDP #090,
Think i am going to use the Melamine Foam McCaster Part 86145K21. Looks like a good compromise.

My search was to insulate a steam boiler. After looking at various hard to acquire foam and foil combination materials that would handle the temperatures, I found polyester batting at the local fabric store in various thicknesses, as well as a inner foil laminated thin version that was used to make hot mitts. This material is good to >300deg F per McMaster and other references, and is VERY inexpensive, albeit a bit fluffy, and had very good insulative properties. There are no toxic particles or debris from it. The first time I used it, there was a little heating smell (some volatiles boiled off), but since works great no odors, etc. Heating duty cycle of the boiler was considerably reduced. I used a combo of the mitt insulation and 1/4" layered material. The lifetime supply (you have to buy it in wide widths) cost about $5 for about 10X as much as needed.
Anyway, it ended up being a very simple solution, and was able to conform to various shapes due to the plumbing irregularities.

Anyone tried radiant barriers for insulating the boiler? Reflectix is one brand that is carried by big box stores. I'm assuming the instructions they have on their site for insulating water heaters can be easily modified for boiler application.

I've used it for tests and it stands up well enough.
I'm just not comfortable with loose bits of conductive material inside a box with lots of exposed high current capable connectors.
