Has anybody used a speed controler such as this

For the heating element you want a 15amp dimmer or variac and by-pass
the thermostat. You will want to put the fan on a separate line to
keep it at full speedhttp://www.coffeegeek.com/forums/coffee/homeroast/329082On Tue, Jan 11, 2011 at 8:15 PM, Bill Chambers  wrote:

Depending on what model top you have you may be able to use a 1200watt
dimmer, if the top is over 1200watts(older galloping gourmet tops) go
with a 1500watt one. Do not use an under-rated one.

And that's just what the HF box is - a 15A (1800W notional) dimmer.  If
anything, it can likely handle more power in an easy resistive load
like a heater - motors tend to stress the triac or SCR more with their
partly reactive load lines).
