Very Nice Wayne!
I wonder about two different things:
What is the intent of the foil wrap on the boiler?
What kind of water are you using in the boiler?
If you are using distilled water, or tap water that is rather soft, you won't get the amount of heating that the boiler is capable of providing. Try putting just the smallest pinch of salt in the boiler next time you run and see if that doesn't make for an improved steaming experience!
