most hot plates cycle that is they turn off and on.this is not good when distilling.its something like trying to drive you car when the cruise control kicking in and out.most that try hot plates
disable the thermostat and use a type of controller,use a heavy steel plate or abandon the idea all together.

As stated above most folks that use one disable or overide the temperature control. Most hotplates are only about 1.5kW. Mine is, and I use it just for my reflux still which has a small 30 litre keg for a boiler. I wouldn't use one on a pot still.

You CAN get 3kW hotplates but round here they are expensive. If you are using electric power you need a good reason to use a hotplate instead of an immersion heater. Invariably the immersion heater is a better option, however the hotplate does mean that you don't need to modify your boiler. They have good and bad points.

Let's take a step back before proceeding... Explain the boiler you are questioning heating with a hot plate... Is this a flat bottomed stock pot or a round bottomed keg...???

From an efficiency standpoint a hot plate should have total contact with the vessel it is heating because they are intended for heat transfer via direct contact rather than radiant transfer... But there are newer models which are solely intended for inductive radiant energy transfer...

Consistent heat input is the most important aspect and eliminating cycling is the only way to achieve that goal...

we gave you the info now its your choice..dont come back asking how to"fix it"
in my opinion the fix for a hot plate is to use it to cook your eggs on.

Perhaps I was a bit misleading with my previous post... It was meant more to mean that hot plates, even if the thermostat is bypassed, are not the best choice for a keg... It was prompted more by the reply by myles than by any input from the OP... I was merely tossing the information out there for any novices who may stumble across this topic... Unfortunately, I got interrupted while posting and ended up condensing what would have been a clearer post if I had elaborated further...

If your pot is from brewhaus (ie., the older tall/thin one) you have the option to use an induction hot plate. They are more expensive than regular hotplates...but they are much faster heatup, and have more control. You can get them up to 1800 (120v) to 3500 (220v) watts. Bottom diameter is about 8.5" so if you have one of the larger pots...this doesn't work well.

I bought a 1800 Wat induction hot plate.and it works great i was a little worried when i read not to put more than 25 lbs. on it :cry: .But i gave it a try and put a 5 gallon wash in the still i filled it rite on the hot plate so i would not drop all the weight on it at one time :thumbup: it work great ran to batches this weekend in it.
