Please --is there a recognized given amount of headroom required in the methanol heating vestle. I'm just in the process of making one in Stainless that will process about 20 gall of glycerol but can size this in height to cope with the required headroom to the vent (meth vapours outlet). I realise there may well be some bubbling and with circulation -splashing and of course the glycerol will expand but how much?????. The diameter of the vesstle will be about 20 inches. Here's looking forward to yet more good advice -Thanks

I always allow 20 percent headspace...just in case.

I use a 48Lt rated water heater, but never put more than 32Lt's glycerine in it.

I use a 120 gallon tank and put 110 to 115 gallons in it at a time.

No pump, no circulation. Just a simple atmospheric still, hence no splashing.
