Does or had anyone used an stc 1000 to control their biab boiler. Is there any reason why this wouldn't work. Mac control temp of stc is 99.9°c so is that near enough for a rolling boil. When mashing it should keep it nice and stay I would think.
stc to control biab boiler?

Once the boiler has reached a god steady rolling boil all you can do is occasionally spray water on the froth if there is a danger of the brew boiling out of the vessel. The temperature is not going to materially increase beyond 100*C.
I use temperature control but for much lower temperatures. When Fermenting its important that temperatures do not fluctuate much around the best temperature for fermenting Ales (around 16 - 20*C) or lagers (around 10*C during first fermentation then around 2*C when Lagering for up to 6 weeks)

For a boiler there isn't much need for automation other than switching on the element. It will boil away just fine without the need for a STC or pid. The only thing against a stc is that is relay controlled rather than ssr which is better suited to heating an element within a narrow band.
i use a WH7016M (30amp version) to drive a economy kettle element for about 2 years - http://www.ebay.co.uk/itm/WH7016M-AC-22 ... 2a2a895f63
to control my BIAB bucket - with the probe in a theromwell, it works very well.
fill bucket, put in bag, set mash in temp, comes up to temp, mash in, reduce temp to desired mash temp, then mash for desired length (or step mash etc), then set to mash out temp, bring up to temp, pull the bag then set to 102c and leave it to come up to boil and beyond.
personally i love it and would have it no other way.

Your a life saver mate Ihave bought one to control my hlt. And cannot find anywhere or aany one that knows what the settings are on these. As they are different from the normal 10a stc I have.

Is your boiler insulated?
I have used insulation on mine its material rather like bubble wrap which has been silvered then over the top of that I've also applied an old Yoga mat. Doing this has enabled me to switch off my boiler at around 70*c to allow for the steep at 66*C. As its a new boiler I'm still learning its characteristics but it does not loose much temp in a 90 min mash, maybe 1.5 - 2*C.
Certainly doing the insulation work is much cheaper than using an STC to control the process.
