I need to insulate my mash tun and was thinking of a hot water heater jacket. Does anyone have suggestions on something better or how to best insulate a mash tun that is a 15.5 keg on a propane burner. I have a RIMS so the burner isn't on too often but I lose so much heat and it just isn't very efficient without insulation. Thoughts and suggestions would be greatly appreciated.
Thanks
