Robc-
I was brewing a batch of Big Bear Stout today and near the end of the mash, the too cold icon appeared even though I had steadily been applying heat above the optimal line. I brewed out the batch successfully, but when starting the boil I hit the heat kettle 5 times and the heat line never moved off of 0%. I reloaded the page and it sent me back to the sparging step, and when I attempted to continue I got to the boil stage and this time the kettle worked but because of the delay the brew line was all the way up to the top. I aborted brewing and proceeded directly to the forums to notify you of this issue. I am not certain how much I was charged for the ingredients and extra heat applications that did not register, but please let me know if you can refund me for the cost of this batch and look into the problem with the heat button issue.
Thanks,
Stoutman
