0.5.6p3 updated the heat mechanism, a new item is needed to make the heater emit a signal (heat detection cover plate). If you don't have it, you can ignore this item.
First type (new version 370K - suitable for coal slurry formulation)
Simple control that only needs one redstone dust and one piston, temperature around 370-380.
Second type (extreme temperature control - suitable for liquid polyethylene)
The temperatures of both devices are controlled around 765-769

Just stick the cover plate here.
What to do if the boiler heats up slowly? Add more machines!
Normal heat pipes need to be connected to the top of the heater, while the alchemy pot needs a heat pipe at the bottom.
This device can keep the alchemy cauldron at a temperature of 700-759. (If you think it's not enough, you can add more yourself.)
Third type (Magic Heater - suitable for 1400K temperature recipe)

New Version (Redstone Line)
New (Redstone Alloy Wire)
Heat Transfer (New Edition) (Extra Content)
Electric heaters can only export heat from the top. Attach a heat transfer interface to one side of the chemical reaction vessel and connect it with ordinary heat pipes. (The alchemy pot does not need a heat transfer interface; just attach it directly.)
You can connect freely, but it is not recommended to connect too many. If too dispersed, you won't be able to achieve high temperature.
