Insulation for boilers - free!

Post by **BobY** » Tue Jul 10, 2007 3:16 pm

Encouraged by a forum post that I read before "the crash", I decided to insulate the boilers on my S1. I'm happy with the result... my boilers cycle much less frequently, and the wiring and electronics are not as exposed to the boiler heat. I used a ceramic blanket insulation -- "Fiberfrax" -- which I purchased from a local distributor. They sold me a couple of cuttings, which is WAY more than I needed. I now have a big box of it that I'm willing to give away, free. There are two batts, 1" thick by 10" wide. One of the batts is 25 feet long, the other is about 2 feet shorter, because that's all I needed. The box is about 19" x 19" x 25". If anyone wants this, and will pay for shipping, they can have it. Local pickup preferred, as that would save me the hassle of shipping and collecting payment.

"CLB" inquired about this just last week. I'll shoot him a PM right now...

I thought you liked the cup warmer?

It's too hot for brandy in the summer. :P

Hey, who told you to store your brandy glasses in the cabinets above the Spaz?!

I usually triple a towel over my cups on the warmer tray, it keeps the cabinets barely lukewarm, they hardly warm up at all. My cups on the other hand will BURN you.

Actually, I still get a fair bit of heat at the cup warmer. This is probably because I didn't go crazy trying to perfectly insulate the very top of the steam boiler (partly because it's kind of difficult with all the wiring and stuff at the top). And the brew boiler is hard to completely insulate because it passes through a metal bulkhead, which makes things awkward.

The steam boiler used to cycle every 3 minutes, and now it's over 9 min between cycles. The improvement in the brew boiler is more modest - it went from 3:30 to 4:40, which is still a 33% improvement, but not as much as I would have hoped. This might be partly because so much of the brew boiler is exposed at the group head. Also because of the tighter temperature control range.

FWIW.

I was just handed a sample sheet of 1" ceramic wool. I will post pix when I mod the machine. It will probably be 1~2 week.

Thanks Niko and Bob for getting me started.
